Free Music Video Downloads – But Are They Illegal

Reviewer — Sat, 25 Apr 2009 13:32:47 +0000

From: Ben Levanger

The internet is the best and easily accessible resource for free music video downloads. Indeed, it has become a hot favorite with the younger generation to search for and play music videos. Some of the popular video viewing websites which offer free music video content are YouTube, Yahoo, and Metacafe. You can effortlessly enjoy music videos released worldwide with a high speed internet connection in your home.

Free music video downloads are being made available in plenty because the primary purpose of these music videos is to increase the popularity of their audio music recordings. Many of these free videos will have completed their premiere on major music television stations and hence are made available for download. Like audio websites categorizing their mp3 collections, music videos available for downloading are also arranged in various categories such as Hip-hop, R&B, Rock, Pop and more.

Currently a number of software tools are available for easy searching and downloading of streaming music videos from social music video websites such as YouTube. One such tool made available online for downloading videos from YouTube is the online YouTube video download tool. The tool requires the user to paste the URL of their favorite YouTube music video, and the tool instantly downloads the video into your computer.

Websites offering free music video downloads give users the option to find their favorite videos by simply typing the names of their favorite artist, and the website can then list videos of that artist for either viewing or download. With mobile phones also being used for video viewing, some websites are providing videos in formats such as 3GP which can be played on all 3G mobile phones. Other popular music video formats available for mobile phone downloads are MPEG-4, RTSP and Flash Lite.

Music videos are also available for portable video playback devices such as Apple iPod, Sony PSP, and Microsofts Zune player. If the video format of downloaded music video is not compatible with your music player, a video converter can do the job of converting video for your portable device.

Whichever website you are choosing for free music video downloads; always check the quality of videos they are offering along with the bandwidth requirements of the website, for faster downloading of videos. To match quality and bandwidth means music lovers are getting a totally new video viewing and downloading experience in a cost effective manner, using the high tech medium of communication called internet.

Video Cable Comparison

Reviewer — Thu, 23 Apr 2009 11:50:54 +0000

From: Andrew Dansby

Video cables used to be simple, there was only one type. However with new television technologies coming out constantly these days video cables are growing ever more complex. I hope to explain the differences between various cables and what they may provide for you. A final note, even though most of these video cables are used world wide, I will be covering the American Television Standard, NTSC (National Television System Committee).

A Brief History

At the start of Television, there was no video cables, there was an antenna that connected to your TV via a spade lug that connected to screw terminals to the back of your TV. Depending on how close you were to the TV station, you may receive a nice sharp picture or a grainy picture.

In the 70’s came Cable, not only could you get a sharper picture when compared to antenna, you could get many different channels, and the quality was consistent. The signal came from a coaxial cable that screwed into the back of your TV. If you had a home made Coax cable, the picture could bleed or cut out all together. Professionally made cables provided a better signal, though a good home made cable could certainly hold its own against a professionally manufactured cable. The better cables had gold plated connectors to provide protection against corrosion.

The late 70’s and early 80’s produced in mass market a device that would change how your TV was viewed, the VCR. Even though the technology had been out for a while, it did not make it to mass production until the 70’s and 80’s. The first VCR’s just used a standard Coax cable that feed the coax used for cable into the VCR and another coax feed out from the VCR to your TV.. Consumers wanted something easier to use, so then came the advent of Composite cables.

A composite cable is a Video cable that has RCA connector jack at both ends. The cable is easy to plug in since there is no screwing as with the Coax. The user simply pushed the composite cable into a connector on the back (or sometimes front) of the TV. No more having to pull your TV out and unscrew a coax cable every time you wanted to switch to a different video device.

In the 90’s there was a demand to have better video quality than a composite cable could provide. A engineer realized that if you separate the various types of video signal instead of feeding the entire signal through a single connector, you could get a better quality video, thus came the advent of the S-Video connector. S-Video provides through a single cable, 4 signals that when separated give a better quality video. The cable was simply plugged into a TV with a S-Video connector and Video quality was improved.

Digital TV came in mass production in the late 90’s. Along with it came a host of differing cables, that gave an extremely sharp picture. The cables varied greatly and do give a slight difference in Video quality, that is measurable even if slight.

A simple guide to video cable quality

Video cables from worst to best

Composite

S-Video

Component

HDMI / DVI

Simple as that, you see the same on many different displays in stores. Let’s go into detail why though.

Composite

Identification. Composite is a Video cable often identified by a yellow colored boot over and a RCA jack at both ends. Sometimes this cable is binded together with a red and a white boot and RCA jacks at both ends.

This video cable sends the video all through one connector, the red and white connectors are used for audio.

Advantage: It is easy to plug into your television and most televisions support this type of connector.

Disadvantage: Out of the four commonly used Video cables provides the worst signal.

Notes: Composite video combines the 3 types of video signal used for an analog video. These signals are commonly known as Y/U/V. Y represents the brightness or luminance of the video and the video, it is also used to send the synchronizing pulse. U and V are used to carry the color information also called chrominance.. The signals are all combined or modulated at the video device (DVD, VCR etc) and sent over the single composite cable. When the signal reaches the Television, it will separate theses signals and apply them to show video. Having to combine and then separate the signals again, means that there is a loss of video signal quality.

S-Video

Identification: S-Video is a Video cable often identified by a dark gray or black boot, covering over a miniature DIN (barrel style connector with recessed pins) at both ends.

S-Video has 4 pins used for video. Each one of these four pins separate out one part of a video signal.

Advantage: A better video quality than provided by composite.

Disadvantage: more difficult to plug in and remove. Connectors can break easily. Not quite as good as component video.

Notes: S-Video was developed to improve some of the problems encountered with Composite Video. By separating out the various video signals and combining them into one connector, the video signal is improved considerably. One of the pins is used to carry luminance (Y) which includes brightness and the video. A second pin is used for grounding the luminance signal. A third pin carries the color signal, a modulated chrominance (UV) signal. The fourth pin is used for grounding the chrominance signal.

With two of the three signals separated a considerably improved video signal is readily seen,.

Component

Identification: Component video is three separate Video cable that has RCA jacks at both ends. The cables are usually separate, but not always so. The boot at the end of each RCA connector are colored Red, Green and Blue.

Advantage: By separating out each of the video signals onto a different cable, video quality is improved over S-Video.

Disadvantage: Not quite as good as HDMI, though it is close. Three separate connectors to plug in.

Notes: Component video separates out the colors as opposed to S-Video which separates out the signals. Component Video cables are associated with HD-TV. When you look at the ends of a component video cables, you would assume that the colors are carried in Red/Green/Blue signals. However the signals are known as Y (luma) , Pb(blue difference and luma) and Pr(red difference and luma). Y,Pb,Pr are for analog signals. It also may be known as Y (luma), Cb (blue difference and chroma) and Cr (red difference and chroma) for digital.

A bit of explanation is needed for Luma. Luma is brightness just like Luminance, however the brightness described with luma is colorless. Luminance describes the brightness of the colors.

Y is the luma signal. Pb is a luma signal plus the blue difference from the rest of the signal. Pr is a luma signal plus the red difference from the rest of the signal.

For a digital signal, the connectors are known as Y (luma), Cb (chroma plus blue difference) and Cr.(chroma plus Red difference). A bit of explanation is needed for chroma. Chroma describes the difference from gray at a given hue and lightness

Y is the Luma signal. Cb is a luma signal plus the blue difference from the rest of the signal. Cr is the luma signal plus the red difference from the rest of the signal.

DVI

Identification: DVI connectors are small rectangular connectors

Advantage: A pure digital signal provides the best video quality.

Disadvantage: More expensive than other video cables.

Notes: DVI cables and connectors are for a digital signal, thus provide the best video quality. They are found on an increasing number of high end televisions and mid level televisions. The signal carried on a DVI cable is associated with HD-TV and provides the best picture to a HD-TV. DVI connectors are found on cable receiver, computer video cards, DVD players and Televisions. However, sometimes one may find that the device may have a different connector than the television. I.e. Your cable receiver may have a DVI and your television may have a HDMI. No problem, converters are available to change the connector.

HDMI

Identification: HDMI connectors are small rectangular connector that taper at an angle on both ends for polarity purposes. The connectors are smaller than a DVI connector.

Advantage: A pure digital signal provides the best video quality.

Disadvantage: More expensive than other video cables.:

Notes: HDMI cables and connectors are for a digital signal, thus provide the best video quality. They are found on an increasing number of high end televisions and mid level televisions. The signal carried on a HDMI cable is associated with HD-TV and provides the best picture to a HD-TV. HDMI connectors are found on cable receiver, computer video cards, DVD players and Televisions. However, sometimes one may find that the device may have a different connector than the television. I.e. Your cable receiver may have a DVI and your television may have a HDMI. No problem, converters are available to change the connector.

As you may see, DVI and HDMI have the exact description in the notes section. There are not many differences between the two that effect the video quality that one can perceive visually. If your cable receiver has a DVI, but your Television has a HDMI, don’t fret, just purchase a converter.

The difference between a component video cable and HDMI/DVI cable is small, but it is still there. If you are viewing the television from up close, you may see a difference, from a standard viewing position, you will probably not notice a difference between the two.

Display Capacity Of Various Video Cables

Composite Video – Capable of 480i, maximum resolution of Standard Definition TV (SDTV). 480i means 480 lines of resolution in an interlaced format.

S-Video – Capable of 480p, maximum resolution of Enhanced Definition TV (EDTV) and 480p (SDTV). 480p means 480 lines of resolution in a progressive format.

Component Video – Capable of High Definition TV (HDTV) at 720p, 1080p and 1080i, EDTV at 480p and SDTV at 480i.

HDMI and DVI – Capable of High Definition TV (HDTV) at 720p, 1080p and 1080i, EDTV at 480p and SDTV at 480i. Resolution is sharper than component video.

I hope that this article helps you with the selection of your video cable. One final word of warning, be wary of ultra – premium cables. Sometimes the only thing you are purchasing is the name brand of the cable. Be way of no-name cables as well, you may get an inferior cable

Video Content in Cell Phones and Other Mobile Devices

Reviewer — Tue, 21 Apr 2009 02:43:43 +0000

From: Daniel

Mobile internet costs

Take a look at US telecommunications giant – Verizon.

Verizon Wireless and other big mobile operators like Sprint Nextel have spent billions of dollars building 3G multimedia networks, and now they have to generate revenue through new services such as paid video. Certainly, these

3G networks are also ideal for carrying other data services such as mobile e-mail and different mobile applications. But using them to deliver music and video content wirelessly is a much easier concept to sell to consumers.

According to IDC, only 6.9 million, or 3 percent, out of 230 million mobile-phone subscribers in the U.S. are expected to view video on a mobile device by the end of 2006. And even though that number is expected to grow, analysts don’t believe mobile TV watching will hit the mainstream anytime soon.

By 2010, IDC predicts that only 9 percent of cell phone subscribers in the U.S. will tune in to TV on their mobile phones.

( posted by news.com )

Verizon take additional $15 per month for its mobile-video services and I think that for the most people it is still expensive. May be in the future this mobile video services could be based on Mobile Advertising platform and mobile Ads revenues can close investments and other costs.

As a matter of fact, in February had launched the first mobile Ads for the iPhone.

Ad Infuse is serving up ads from Esurance and the Partnership for a Drug-Free America on several sites, including Health & Fitness Mobile for Men and MondoMedia.com. (posted by news.com).

The Ads effect in iPhone was not good, because the tester had to wait 5 min Ads downloading process. The main problem was a slow internet connection in iPhone. It could be better, if mobile infrastructure can tune mobile connections and mobile video stuff.

Mobile video content quality

The other basic aspect to win new customers in mobile multimedia niche – the quality of mobile video content.

Sure, that all people would like to watch videos only in good quality, they are all take care of eyes!

We are talking about DVD length movies for iPhone or cell phones.

Good quality video content take a lot of time for encode-decode video in appropriate mobile video format with the best video / audio options for different cell phone models.

Any way, it’s a lot of work (time and money) for companies, which deliver this ready video content to mobile carriers.

Another alternative for mobile fun is YouTube mobile service. It’s free for use, like YouTube web site version, but they are only amateur videos and other video stuff, but also here exist a lot of limits, e.g. your cell phone need to support RSTP data streaming protocol, your mobile carrier must provide RSTP internet connection and so on. I am talking now only about US and Canada for other world this service is too expensive and now a day not supported from mobile operators.

So, a good quality mobile video content is additional investment for mobile operators, who want to take a big part of pie in this mobile niche, but it’s still in development process!

——————————————————————————————————————————————————————-

We have also other alternative to watch videos in cell phones, this aspect we discuss here.

In Internet you can find a huge of software and online video solutions.

I am convinced, that today this method (for watch video content in cell phone) use 90 % of people in the world, inclusive USA and Canada.

If you use software solutions, it takes a lot of time to find your favorite video, convert it in appropriate mobile video format (e.g. 3gp video format) and than transfer converted video to cell phone (via Bluetooth or USB cable). Well done! After all this steps you can watch this video in cell phone.

Basically, software solutions are difficult for normal internet user and you have to purchase it.

The main difficult position, using software video convert solutions is to know all video / audio options for converting video (video bit rate, audio bit rate, video size etc.). For example, for 60 min DVD movie you will spend 25-30 min of time if you know the right video convert options plus memory in your cell phone.

Other negative aspect is available memory in your cell phone for store converted videos content.

Sure, that memory in cell phone is limited factor and therefore it is disadvantage for most of us.

It’s not a secret, that everyone would prefer to use mobile video content in cell phones and iPhone, saving the time and money at the same time!

Now this perfect solution for mobile video content search many companies!!!

In the next time, we will discuss the great aspect, how to watch videos in cell phones, iPhones without spending much time for convert videos to cell phone and store it in mobile phones, do not thinking about memory space!

Stay tuned – we will write new reports!

Make Money With Online Videos: How to Use Online Videos to Boost Your Income!

Reviewer — Mon, 13 Apr 2009 08:23:51 +0000

From: Jeremy Gislason

ow to make money with online videos gives you a massive edge over the regular marketer. If you know how to create videos using some of the tools readily (and oftentimes cheaply) available at your disposal, you should be able to outdo many of your competitors using video marketing.

Videos are just an excellent way for you to create immediate traffic and build credibility. Thousands of visitors may go to your site if your video becomes viral. By just creating an interesting 3-minute clip, and uploading it to video-sharing sites, you could get instant exposure and make money with online videos.

How do you make money with online videos the right way?

First of all, know that marketing videos isn’t one of the loved practices by marketers because it involves more effort, video know-how, and perhaps a likeable personality.

All of these qualities can be learned and developed, but some marketers are too lazy. Video creation can be outsourced to freelancers, but it may cost a lot, and it won’t have the same personal touch as when you’re the one talking.

Nonetheless, the advantages of using video presentation are good from the side of building credibility and gaining trust from your viewers. With that as a fact, don’t be afraid to make videos from scratch in order to gain market territory, even if it’s your first time. You’ll find it exciting to do once you’ve got the momentum going.

One of the steps for effective video creation so you can make money with online videos is to make a script. A video script is nothing else than a piece of paper that has everything written from start to finish of your video.

You start the video and put your written script either below or on top of the camera, you read the script and you speak every word that you wrote on it.

The key when taking such action is reading the script very closely to the camera, so your eyes are glued in front of the camcorder lens. Usually the great majority of those who see you on video won’t even notice you are actually reading a script.

The ultimate key for the successful creation and finish of your video depends on having a clear voice and tone, and the way you communicate the message. Make sure you impart your message in an interesting, curiosity-arousing, or controversial way.

If the tone and the way you say things on your video are effective to your targeted audience, you should have a video that creates great credibility and opens trust from the recipient’s end.

So could you make money with online videos immediately? Most likely yes, if you already have an established website with a powerful marketing system in place!

Should you use video marketing as part of your promotional efforts to look for more clients? Definitely! If your purpose is to build your credibility, earn more trust, and connect with your audience, then video marketing is an excellent option.

Is there an easy way to upload your videos to a variety of video-sharing sites? Fortunately, there is. It’s called Tubemogul. Simply sign up for an account at tubemogul.com. At first, you have to register for each video sites if you haven’t done yet. But after you’ve signed up, you can save their login details in tubemogul, so you can easily upload them simultaneously from then on.

Another important tip to make money with online videos is to put them on your own site or blog. Video makes you more “real” to people. Use the embed code provided by youtube on your site, because every visitor that watches your video (using the embed code) would add to your view counts. You’re probably already aware of the law of social proof – The more views your video has, the more people will watch it because they tend to follow the crowd.

Is video necessary for your business? No, there are many other methods you can use to promote your sites. However, video marketing is one of the most effective tools to use. So if you want to get the upper hand on this competitive marketplace, you should consider video marketing. It’s time to make money with online videos!

Getting the Best From Your Video Productions

Reviewer — Sun, 12 Apr 2009 07:14:23 +0000

If you are producing videos for the purpose of getting traffic and conversions to your website, you’re not alone. Thousands of people are doing the same thing, so it’s very easy to get lost in the millions and millions of videos that are available on the various video sharing websites.

Often it’s hard to get lots of views to your videos, because it’s the videos with the most views and comments that typically show up at the top in the search results on the video sharing sites, and those are also the videos that get promoted in the related results when someone watches a video. So how do they get those views in the first place?

The most common way videos get a large number of views is through word of mouth. Viral marketing is alive and well in the video sharing world. When people see a video they like, they tend to tell their friends about it. If the video is really good, it gets passed around and around and it goes viral.

Unfortunately this viral feeding frenzy usually only happens to videos that are really off-the-wall. A celebrity doing something shocking, someone being humiliated in public, or a really stupid criminal could have their videos go viral pretty easily. A video about trout fishing or about making money online has less chance of going viral.

In this case, you have to find a way to inflate the views yourself. No, I’m not saying you should use some kind of bot to artificially inflate your views! That’s a great way to get banned. Luckily, there are loads of ways to get views to your videos without being dishonest.

First of all, you should get everyone you know to visit your videos. Post a link to every video that you create on your own blog. Send a link to your email list. Put a link in your forum signature. Use social bookmarking to drive traffic.

On most networks, like YouTube, you can post responses to video’s. If you find a video in your niche that is already popular, you can post your video as a response to their video. This will mean you get a link from their video’s page. Keep in mind that some networks require these responses to be approved by the original poster.

In the description of every video you post, you should ask viewers to subscribe to your channel if they enjoyed your video. Most video sharing sites have a way for people to subscribe to see more of your videos so don’t forget to ask people to sign up. The more people you have subscribed to your channel, the more people you’ll potentially have visit every video you make later.

Comments are also a vital element to popularity on many sites. Comments are especially important on YouTube, for example. Always ask people to comment in your description, and at the end of the video itself, if it is possible.

The wonderful thing is that the effort you put in will be rewarded many times over. As the number of views of your video increases the more likely it will be to appear in the search results and other listings, which in turn means yet more people will stumble upon it, and that will give another boost to the number of views and who knows, before you know it, your trout fishing video might just end up going viral.

Web Video – Is Video Advertising Expensive For Your Business, or Well Worth It?

Reviewer — Sun, 12 Apr 2009 00:30:11 +0000

From: Sam Stevens

If you are already advertising on the internet, you know the costs of having banners or pop up ads. Video advertising is not that much more and is twice as effective. If you do not believe this check it out. You can try this for a month and see if you get more stats on the video ads or the banner ads. Most advertising engines agree that their customers get many more views on their video advertising than plain text or even photo advertising.

Cost will depend on how you wish to use the video to market your business. If for example you simply want to use a video on your website, it will not cost anything, besides the uploading of the video into the website. If you want a more professional looking video for your website, there are plenty of companies out there that provide this service for much less than text advertising. You can have a slick ad or you can have one that is home made. Sometimes, the home made videos tend to stand out more.

It will cost you slightly more to have your videos featured on other websites where you advertise. More than a banner ad or a line ad. But again, how much is your business worth to you? If you want to see how effective this medium is, test it out.

If you have a small business and want to advertise for free, there are plenty of places on the internet where you can post your videos. They will also give you stats on how many people have viewed your video. On some websites, the videos are rated.

There are many professional companies that can help you out with video advertising. They can offer everything from creating the video, uploading onto the proper websites to even using it in e-mails to your clients. Many businesses keep a data base of their clients. If they don’t, they should. From time to time, they have sales or promotions and wish to contact their clients by e-mail. E-mail is very inexpensive. Actually, it is free. You can either hire a professional to e-mail your clients your advertising video or do it yourself to save even more money.

Writers are gaining publicity for themselves by using videos on writing websites. They upload a video of themselves and talk about their work. This is an excellent way to get people to read your work, particularly if you are on a site that pays you for page views. You can do this in an interview format, or simply have someone film you talking about yourself. This is free.

You can also promote yourself or your business on YouTube for free. Or MySpace. Camcorders have come down significantly in price. Many are around $100 or even cheaper. Each year the price goes down and the quality goes up. They are easy to use and the contents can be uploaded to your computer with ease. Then all you have to do is decide where you want to “advertise.” If you are advertising a small business, your art, or even a political cause, you can put it on a site that offers free video uploading. When you compare the cost of video advertising on the internet to an actual commercial on television, you are talking apples and oranges. Video advertising is much cheaper and even small businesses can afford a professional agency that can take care of this for them.

How many of you get e-mails from businesses with which you have previously had a relationship? Most of you do, I would suspect. Even if you clicked on their ad by some mistake, they will contact you via e-mail. As said previously in this chapter, e-mail is free.

Now imagine that you get an advertisement from a business that has a very funny video attached to it? You will be entertained and not forget about that business. It may even prompt you to take a look at their sale or new promotion.

I saw one of the most effective and clever uses of advertising on the web recently. I was taking a look at shower filters. Instead of just a website, like most of them, that featured shower filters and explained the advantages of having one of these gadgets, this one had a scene from the movie “Psycho.” Yes, the shower scene. The caption was “Remember when the only thing you had to fear about the shower was….” and then it stopped. We saw the familiar scene of Janet Leigh in the shower and “Mother” coming through the door with the knife. It was clever, entertaining and certainly caught my attention. In fact, this was the company that I decided to purchase the shower filter from.

How much did this ad cost them? A little more than a regular video ad. The film “Psycho” is not in the public domain so they had to pay synchronization rights to the producer to use this on their website. But synchronization rights on film even for the internet are based upon seconds. They did not have to pay for the rights for the entire film, just a brief portion of the shower scene.

If you have a clever imagination, you can film your own video that will attract attention to your project in the way that this shower filter company did. You can purchase synchronization rights from film producers if you want, or you can simply make up your own video. Also, be aware that many films made prior to 1962 lie within the public domain. This means that they are free to use. Clips can be obtained from all over the internet, or can be downloaded from your television or DVD player. You must make sure that the film is in the public domain, however. The way to do this is to check with the United States Copyright Office. There is also much information about which films lie within the public domain on the internet.

No, it is not expensive to advertise using video on the internet, particularly if you are advertising on your own website or e-mailing your customers video advertisements. Just make sure that the advertisements are not too long or it may bore the customer, no matter how entertaining it may be. You do not want to go more than 30 seconds.

If you decide to use an internet advertising agency, they can keep track of the amount of customers who view your video and make sure that they are placed in the proper venues.

The cost is not that much more than banner ads and may be well worth it. Banner ads are sometimes clicked on by accident, giving false stats. A video ad, however, can be managed where the person has to click on to the “play” button to view it. Once they begin viewing, chances are that they will continue to do so. Either way, at least you will have an honest count of viewers when it comes time to pay Google or whoever you are using for your internet advertising. In a way, the difference in the quality of the views more than makes up for the price difference in advertising.
