best compression for full screen video
on Oct 19, 2007 at 7:50:58 pm

I have a client who wants to post videos over the internet but wants something full screen and really good quality
I created a 640x480 flv file for him using the on2VP6 compression
http://www.egeefay.com/espublic/Test/FullScreenTest.html
The movie seems to play in realtime...and looks good to me
But the client isn't happy with it. He says he's seen internet videos that play full screen and look sharp as a tack
Anyone have any suggestions on a better compression format than
flv?

What format was it shot on and were you given that source file or when that was further compressed?

What was your data rate?

What software are you using to compress it so we might make specific suggestions?

Was this shot with a pro mist filter or equivalent? It has that Barbara Walters look if you know what a mean.

Well for starters you're using just about the worst program to compress your video.

Render out of AE uncompressed, and then use an advanced compression program like Sorenson Squeeze or On2 Flix Pro - it will improve your quality greatly.

AE, while able to compress is not designed to compress and has no tools for quality upkeep.

Watch this video for a basic understanding of the problem - it's just an intro, but it makes the point:

Without advanced compression software, your video will never look as good as it can.

But that said, if you don;t have the option of using/buying squeeze or flix, try increasing your data rate a bit. It can only go so far, but maybe it will help. It will also make your file a lot larger. Squeeze (for example) can keep the file size lower with drastic improvements in quality.

You've got a problem there - Flash simply doesn't offer good scaling quality to full screen. Even if your encode @ 640x480 is perfect, it won't look good on larger screens.

Although I agree that you should be using a dedicated encoding application and that Flash does not scale well (up or down), it is possible however to achieve 'great results' at full screen.

let me add that it depends what full screen is. Full screen at 800x600 will look better than full screen at 1024x768 and on up. My display is 1600x1200, anything short of Quicktime HD does not look great full screen.
I have seen some good full screen video using DIVX, however most people do not have DIVX player.
Quicktime MP4 or H.264 can give very good results, but fewer people have Quicktime than you might think.
The new Flash Player 9+ supposedly plays MP4, so we are eagerly waiting for that to equalize the playing field for online video, and allow us to use MP4.
