I'm using HC 19 with the pulldown feature enabled when processing a 23.976 FPS video. On the initial configuration screen HC reports the movie length (and encoding length) as 137617 frames and 5739.78 sec or 1:35:40 hms, which is correct.
After encoding, the resulting M2V file has all of the frames, but the duration is 5733.83 or 1:35:34 hms. What's happened to 6 seconds of the video? If I mux the audio with the video, it is grossly out of synch! I can fix the problem by using DGPullDown and doing a 23.976 -> 29.97 conversion on it, but I thought the pulldown feature of HC was supposed to make this unnecessary.
If you divide the number of frames by 24 you get 5734.04 seconds which is approximately the duration of the M2V file. It seems HC is calculating the duration based upon 24 rather than the real frame rate of 23.976.
Am I doing something wrong, or is this a bug in HC?
