I'm in the process of making several DVD's from various tv/hd captures, and one thing I am stumbling with is setting precise chapter points for various video clips in Scenarist. I know how to force an I-Fram in CCE by editing the .ecl and adding the frame numbers, but this doesn't translate well into scenarist.
What I have been doing is finding the frame that I want to set as a chapter by opening the avisynth script in virtualdub, and then write down the time code and frame number.
Then I add the avs to CCE, save the .ecl and edit that to manually add the chapter points using the frame numbers I wrote down. After encoding I use pulldown.exe on the mpv to enable 2:3 Pulldown and the Drop-frame flag. After that, I rename the video to a .m2v and pull it into Scenarist.
Then to set the chapters, Scenarist wants a time code, so I enter the time code I wrote down and hit enter to jump to that spot in the video asset. When I click the "New Scene" button it sets a new scene at what I assume is the nearest i-frame, but it never seems to line up with the exact same time code.
Now, I understand that is because when I apply the 2:3 Pulldown, it alters the frame rate, so the number of frames increases, and the time codes will be sightly different, however I am wondering if there is a way to be sure I am in fact hitting the I-Frame I manually set in CCE. I noticed that when I open the VIDEO_TS in WinDVD for testing, I can jump to the next or previous chapters, but there is often times a blip of audio from the prevous chapter that plays. I'd like to avoid that since the frame numbers I wrote down are precisly at the beginning/end of the segments. Perhaps it because the AC3 needs a sort of "I-Frame" at the same time?
Actually, I am kind of hopeing that there is a much easier way to set these chapter points (secenes) in Sceanrist without using the mouse to pull the scene edge to one side or the other. Is there some way to frame-by-frame through the video? My chapter points are in a pretty small window of 10 to 15 frames of blackness (the commercial cuts of a tv show) and there are over 80 episodes I am doing this on over several discs, so faster is better...
Here are some of the chapter points for the videos I am putting on one disc, just to get an idea of what I am looking at. I have these saved in my .avs scripts which is why they are commented. It's got the Timecode according to Virtualdub and the frame number. Remember, this is from a 23.976 video clip that will later get a 2:3 Pulldown to 29.97.
