I have received .mov files from my wedding videographer that was shot on a Nikon with a 1920x1080 and 25 frame rate. Originally I had tested his clip and it was viewable on my mac osx 10.8.4
I tried to view his new shot clips that were shot at a 1920x1080 frame rate of 59.9 h.264 compressor and although I can open and view them, quicktime doesn't play them smoothly just very choppy. The clips however are perfectly viewable on a pc.
I tried importing into FCP 7 and same thing- very choppy and not continuous playback.
How do I find out what codec I need to download for playback and most importantly use in FCP?
Also it is a nightmare to mix frame rates like this. If the 59.94 shots are meant to be slow mo then that is OK. You use Cinema Tools to change the frame rate to 25. If they are not slo mo then you will have to convert them to 25 to match the other shots before you can edit in an FCP7 timeline.
Are you in a PAL country or NTSC becasue maybe there is a double problem with the 25 fps footage. You need to know what the final frame rate is going to be to work out the best path. In the end what do you need to produce as the final format
