I've got some helpful info on some stuff I'm doing with this so far from other users, and now I've come into another set of problems.
Currently I have two video streams, one progressive and one interlaced. Both streams have been checked and flags are set correctly for both streams. (ie, progressive has the RFF and TFF and progressive flags set correctly. The interlaced stream has not RFF and TFF always True and progressive flags always false)
The source was a laser disc with interlaced and progressive telecide source. Did I say that right? 30fps and 24fps sources (yes 24fps it's film)
Now both streams are in the same VTS inside scenarist. The progressive stream was set with pulldown to 29.97 frame rate, drop frames set to true, progressive frames true, progressive sequence false (haven't found a reason to set this yet).
Interlaced stream is standard no messing with the flags.
Inside scenarist I've got the progressive streams, audio and video, as drop frame type drop frame. The interlaced stream is set to no drop frames. I've read conflicting things on mixing and matching these settings. I don't see how I could do this any other way...
The interlaced playback seems jerky.
I checked the VOBs and the first VOB contains both the iterlaced and progressive streams. This is what I'd suspect, it's suppose to be all flag driven. The flags appear to be set correctly. The first VOB is 26 minutes long and the first 22 minutes is flagged for interlaced, the last 4 is flagged for 3:2 pulldown. All the other VOBs are flagged for 3:2 pulldown.
So, any ideas on what I'm doing wrong and how to get the video segment to play smooth? Should interlaced be set drop frames to true? In the video stream and/or in scenarist?
Thanks for reading the whole thing, I'm really confused as to where I went wrong....
