new bug or how it always worked? 'same as source' framerate.
Posted: Fri Jan 12, 2007 8:10 pm
I was just compressing some interlaced source (Robert Plant Sound Stage DVD) and had selected 'same as source' for framerate. When watching the compressed file (using 2 pass 1250bitrate H.264 baseline iPod, the Jan 1 UB 7.1a4 build) I notied the ending credits were jumpy. So I recompressed it choosing framerate of 29.97. The resulting file didn't have duplicate frames, so the source must have been 29.97 as well.
Is this a known longstanding issue with HandBrake, or is this something new?

Known issue. I'm working on writing something up on it, but in short, it isn't a HandBrake problem...it's a DVD mastering problem, or more correctly, an issue with the way the DVD IFO definition was created.

gotcha, well, it's not too hard to check it to make sure.... interlaced source is *usually* 30fps, so that should have been a tip for me (:

Do not forget PAL DVDs...

So, if I get some jerky pans in movies where ffmpegx reports the original VIDEO_TS as 29fps, I should set Handbrake's fps to 29 too? My first attempt using 'same as source' produced a 23.9fps avi, and I noticed one pan in particular was pretty jerky.
How about where ffmpegx reports the original as '23.9 w/3:2'? What Handbrake fps setting should I use?

why does handbreak use the IFO information to decide on the FPS? is it possible to have it "test" or look at the actual video?
this way it would not fall to the knees of bad dvd authoring.
