The film was shot HD 1920 x 1080. All the files (with the exception of one that is HDV 1080i 60 and another that is a slightly smaller size 1440 x 1080) are Apple ProRes 422, 48. KHz, 29.97 fps.
When I go to file–> export–> quicktime movie, I get options to change settings (the codec), to include audio and video, markers, recompress all frames, and make movie self-contained. I’ve been choosing the Apple ProRes 422 option, audio and video, and make movie self-contained.
The second thing I’ve tried to do was file–> export –> quicktime conversion. I adjusted the settings here as well according to my files (Apple ProRes 422 and so forth). The last time I did this, it told me the file was too big halfway through exporting. Previously though, it would export along with two reference files that are probably referencing the video because the audio always works.
