Using vfr Causes Video To Be Weirdly Jumpy

Post by Blairboy »

I've tried this with the latest svn build and 0.92. Using the --vfr flag causes some weird results. If I play the resultant video (I tried special features from Shaun Of The Dead and an episode of Friends) in totem-xine or mplayer, the sound is in sync, but the video is all jumpy and whatnot. If I play it in vlc, the video is fine, but the audio is jumpy at parts. I wanted to use the vfr to get rid the interlacing on these videos, but its being all kinds of strange. Anybody know something I don't?

Also, here's what a partial encode gave me using vfr in the svn compile

Code: Select all

$ ./HandBrakeCLI -i /dev/hdc -E ac3 -a1 -t6 -e x264 -T -b 2000 -x bframes=6:me=umh:subme=7:b-rdo:cabac:analyse=all:8x8dct:b-pyramid -V -o /home/munkduckpup/Desktop/Friends\ s01e01.mkv -P -v

Re: Using vfr Causes Video To Be Weirdly Jumpy

Post by jbrjake »

To isolate the problem, see if anything changes if you get rid of b-pyramid, and then if that doesn't work try getting rid of b-frames. If that doesn't work, try using MP4 instead of MKV. I do most of my testing with MP4. But if I turn off b-frames, I get good playback with VFR in MKV, too, using MPlayer and VLC.

So I'm not so sure it's VFR causing your video to be jumpy.

You're a lifesaver. It was the pyramidal b frames option that was mucking it up. As a side note, I detest telecined crap. Barg.
