Video File Compression Like The Broadcasters Do It

Video file compression is a very mysterious topic and something that confounds many people especially when you want to deliver your video in different formats to play over many platforms. You may know that you should export your videos to MPEG 4 to play on the web or MPEG 2 for DVDs, but may not really know just what the heck that is.

So what exactly does MPEG mean?

MPEG is a compression of your video files that eliminates redundant and non-essential image information from the file. However once the video is compressed, it can never be restored exactly to its original form. So why would we want to do that to our video footage?

With discarding this data, MPEG compression dramatically decreases the amount of storage space required to record, store and edit your video. The great thing about MPEG encoding is it will eliminate those parts of the original video data that will not be noticed by the viewer. The end result are video files that can be transferred more quickly to a format – DVD, Blu-Ray or online video player – for high quality playback.

There is now an explosive demand for MPEG compression software, especially for the video-on-demand industry. Software, like PixelTools, can creatively store and recall any data that it processed.

I stopped by the booth and had Mark Conover, PixelTools, chief technology officer, explain this to you in this 3 minute video. He also introduces you to their popular QuickTime Plug-In HDProQT that plugs into popular editing programs and provides reliable export of broadcast and upload ready video directly from the time line.

(If you’re unable to watch the video on this page, go to YouTube to view it.)

Although this encoder is a bit pricey,$1,495.00, you see in the video how if you are working with HD files, the investment would quickly pay for itself in time savings. This is why broadcasters and companies such as Netflix rely on it for their video file compression.

    Excuse my ignorance, but I must be missing something here. Handbrake does this conversion/compression extremely well for free.

      Brian,

      Thanks for letting us know about Handbrake. PixelTools plug-in was more designed for the broadcast market and as Mark shared in the video, it does this very quickly. I would suspect there’s a lot of other benefits that the open source program doesn’t do but I’ve not worked with either.
