| importing a quicktime file that was exported from FCP using h.264. I'm trying to export to flash. I press encode and i get a ding, a file, but zero kb in size. Any suggestions? Heres the codes i get:

| OK i have answered my own question!
If you click on Invert mapping which is under the audio tab. It fixes the issue!! I can export to flv! But i have a new problem. When it exports it only exports 10-13 seconds of footage and the footage is missing a lot of frames. Its very very choppy. any suggsetions people? | ||

I don't know about "only 10-13 seconds", but the missing frames seems to be related to ffmpeg's stream mapping. For conversions without inverted mapping, the output is smooth, but whenever the mapping is inverted, you'll see the stuttering like it is only doing 2 frames per second. | ||

| I had the zero KB issue as well converting a .mov to .flv, and I think I've narrowed it down either to using an exported self-contained movie from Final Cut Pro rather than exporting it to a quicktime, or from not having and using the flv progress bar plugin that's now available on the ffmpegx site. I'm still getting out-of-sync audio and video, with only about half the video encoded, but that's another thread. ;) |
