I have two copies of my video. One is the DVD clone (TS_VIDEO folder). The other is an h264/mp4 transcode made using handbrake of the entire TS_VIDEO folder. The total running length (according to VLC) is different by about 6 seconds. The video is approx 1.5 hrs. When I get to the same frame on both videos, the elapsed time is different. The elapsed time difference between the videos is different at various points in the movie. At one point the difference is 31 seconds. At first I didn't tweak any video encode settings, I used the defaults for "high profile". Then I re-encoded with "constant framerate" option. I've tried various settings, but the end result is the same: all hand-brake encoded vids have identical timestamps throughout the movie, but they all differ from the ones in the TS_VIDEO version of the vid. What's going on? Is this normal?
