Hey thanks! Compression markers did the trick. Your post lead me to Ken Stone’s page where he explains a bunch of stuff.

[Craig Seeman] “You may need Flash Cue Points as Navigation points. I’m not sure if this is implemented in H.264 Flash spec yet.

If I can only convince Compressor to insert an i-frame at the location of each Chapter Marker then I’ll be able to seek to those locations in flash. So I don’t really need any special Adobe stuff, just garden variety i-frames at the location I specify.

Thanks for the response! More details on what I’m trying to accomplish.

I’m using FCP to encode an MP4 using the H.264 codec. I’ll be playing it back later in flash and I want to be able to seek to a particular frame in the video. So I want to insure that that frame is an i-frame. I trued to do this using Chapter markers but that didn’t create i-frames that matched the chapter markers.

As a test I set the keyframe interval to be 300 so that there was an i-frame pretty much every 10 seconds. However, I had chapter markers every 3 seconds or so. When I tried to seek in flash I could only land on the 10 second intervals. If possible, I’d like to have i-frames every 10 seconds in addition to forcing each chapter marker to also be an i-frame.

I believe the codec supports this, but do the tools?
