It is common to skew the clock rates to achieve frame rate changes.
+/- 0.4% for going between 24 and 25 fps. +/- 0.1% for changing between 1000 and 1001 frame base. See the front panel of this sync generator under the audio sample rate settings as an example: http://www.rosendahl-studiotechnik.de/nanosyncs.html -Reuben _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
