We use it all the time at work using Cinema Tools. I'm sure this is a very specific feature only possible in the quicktime mov wrapper. It is controlled by changing metadata or header info. One has to consider also the change in audio sample rate by the same ratio. Anyway if it helps I can provide the same sample movie at different fps, conversion made with Cinema Tools. BTW, in Cinema Tools, this process (understandably) only works with intra-frame codecs (prores...) and PCM audio. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
