.MOV is the file extension used to identify an Apple Quicktime Movie. .MOV is an extremely common sharing format, especially among Mac users. It is considered one of the best looking file formats. While MOV files do look great,  the files sizes are extremely big. Due to the fact that QuickTime hasn’t been a Mac-only program for quite some time, QuickTime versions and players exist on almost all PCs. The vast majority of the videos we personally upload to the web are QuickTime format, followed by MPEG4.

MPEG was developed by the Motion Picture Experts Group. This international group was established in 1988 to develop standards for digital audio and video formats. However, they’re just one of many groups looking to standardize and develop new technologies for digital video.

A .WMV file indicates a windows media video file. Windows Media Video is used for both streaming and downloading content via the Internet. Microsoft’s Windows Media Player, an application bundled with Windows operating systems, is built for WMV files. WMV files are of a pretty small file size, actually one of the smallest. As a result of the low file sizes, the videos are compressed so much they start to lose their quality in a hurry. In fact, I’d say the resolution is pretty crummy in comparison to modern codecs. But a tiny file size can be a real advantage in some situations. If you get an email with an actual video attached instead of just a link to a video, it is probably a wmv file. They are the only ones small enough to attach to an email.

MPEG-4 is another great sharing format for the internet. It’s a small file size, but looks fairly clean in comparison with other video codecs of the same file size. It’s the video format employed by a growing number of camcorders and cameras and it is highly recommended this day and age.

In fact, YouTube actually recommends that users upload using MP4  format. YouTube accepts multiple formats and then converts them all to .flv or .mp4 in their back-end for distribution.

As mentioned earlier, more and more online video publishers are moving to MP4 (with H.264 as the video compression codec) as the standard internet sharing format with use within both Flash players as well as HTML5 and most mobile devices. This is the format that we recommend for online delivery of your media.

AVI format is a long-time standard developed by Microsoft and has been around as long as digital video has. AVI files (particularly when uncompressed) tend to be HUGE, way too big for the internet or uploading to someone. AVI is more for the beginning of a video project using it as something to edit off of, not the end. In that sense, it is not really a sharing format. They’ll slide into just about any video editing program and the quality is still high enough to be a master clip.

AVI is windows-based and is virtually universal. The problem is, not all AVIs are created equally and you can still run into compatibility issues due to different codecs on the videos. The important thing to know is that whatever streams inside the container (AVI) is not necessarily the same from one AVI video to the next because the codecs used for compression can vary from file to file. This is because AVI is what’s known as a “container format”, which basically means it contains multiple streams of different type data, including a control track and separate video and audio streams.

Flash video (FLV) is the single most common sharing format on the web today. You’ll see the .FLV file extension on videos encoded by Adobe Flash software to play within the Adobe Flash Player. Virtually everyone (99%) has the adobe player installed in their browser and so this has fast become the most common online video viewing platform. Almost all the video sharing sites stream video in flash. You can upload formats other than flash, and those sites will convert it into flash for streaming to the end user. Notable users of the Flash Video format include YouTube, Yahoo! Video, MySpace, and many others.
