    We are re-purposing older video into a web app for training purposes. The source video isn’t an option, unfortunately.

    Thanks! I was using FCP to convert and see the error of my ways. I used MPEG Streamclip to make an uncompressed file and the red flashing is gone.

    The older computer is a first-generation Intel macbook pro, and it’s in a custom Flash player in Firefox. It’s been reported that there are still problems with the new video, but it definitely seems more stable from here.

    In your experience, is uncompressed the best option? Should I be trying something else? I’m actually changing the frame rate to 30 rather than 29.97 since we ultimately want it at that rate for multi-media navigation purposes. Does that have an effect?

    I’m a little out of my league at this point and really appreciate the help.

    I gave up on this and didn’t see your reply until just now.

    The answer to your “why” question is both. It’s a highly specialized situation and there are folks here trying to get it perfect. It would be great if it all worked out that way, but I remain completely out of ideas. Thankfully, this problem was solved through the magic of the programmers.

    So, that solution worked beautifully, except the key frame for every 8th second is off. We’re speculating it’s because 1/15 = 6.666666666666, repeating and there’s some crazy math that throws it off on the 8th second, but that’s just a guess. We found a way to work around it in our player, but we’re still wondering what’s going on. Any ideas?

    Thank you! I had read that NTSC was offset from 30fps by 1/1000, but I didn’t know what to do with that information. That explanation is just what I was hoping for!

    We tried exporting through Compressor, but I was not successful inserting keyframes every second in an h.264 file. Do you know how to do that?

    Did you bring it into Photoshop and run it through Filter>Video>De-Interlace?
