Boils down to this:

There’s a new profile for the On2 VP6 codec, called VP6-S, that will be available in the Flash Player 9 update 3 (”MovieStar”) release, currently in beta.

VP6-S is a new profile designed to utilize LESS processor cycles for bitrates above 500Kbps (read between the lines: high-res SD, or near HD resolutions or higher).

So, moving forward, we’ll have four options for standard Flash Video delivery:

  • Sorenson Spark for Flash Player 6/7 or higher compatibility (and/or slow device processor speeds)
  • On2 VP6-E for Flash Player 8 or higher compatibility
  • On2 VP6-S for Flash Player 9 update 3 or higher compatibility (and > 500Kbps bitrates)
  • AVC/H.264 (MPEG-4 Part 10) and AAC audio for Flash Player 9 update 3 or higher compatibility

If you’re making the decision in the next few months to push the envelope with Flash Video and Flash Player 9 update 3 technology, how do you know whether to use On2 VP6-S (or -E) or AVC/H.264?

  • If the client needs to repurpose video assets in other non-Flash platform environments, H.264 is probably the best bet. Be sure to communicate commercial licensing concerns for H.264 delivery to the client.
  • If you want to avoid licensing concerns and have high-resolution (high SD or near-HD resolutions), use On2 VP6-S.
  • If you need to perform custom effects with Flash Video (embedded cue points, alpha channel transparency), use On2 VP6-E/S.

Those are my thoughts for now. I’m sure I’ll have more to report after next week’s Adobe MAX conference.

In my new Adobe Press book, Adobe Flash CS3 Professional Video Studio Techniques, I provide an Excel spreadsheet (.xls file) to help readers compute video and audio bitrates for Flash Video (FLV) files. I finally had enough spare time to build a Flash version (.swf file) that runs in Flash Player 9.0.45 or higher.

I’ve also built Windows and Mac projector versions of the FLV Bitrate Calculator. Enjoy!

UPDATE:

You can find an updated AIR application version of the bitrate calculator, featuring improved calculations for AVC/H.264, here:
