Stupid question: you guys do force film the video in DGIndex before using the script, don't you?
Yes, force film is a must.
I think I would rather IVTC in AVS then use DGIndex's Force Film since its very hit n miss. Although I have never tried it on the GOUT so it could work well in that instance.
Any thoughts on that g-spot?
CompMovieGuy: What? I know you've done a lot of great conversions, but this doesn't make any sense. I'm assuming I'm misunderstand you, but for others who might not know...
DGIndex's force film doesn't inverse telecine video!
DGIndex INDEXES mpeg video so a frame based program like avisynth can work with it frame accurately and non-linearly as it would AVI content.
Force film or honor pulldown flags just determines if avisynth (or whatever program) will soft interlace progressive content whenever a pulldown flag is present.
I.e., add pulldown & interlacing where it isn't present in progressive material.
The only reason to use "honor pulldown flags" instead of "force film" is if your source is not 100% progressive (less than 95% is the rule of thumb, DGIndex will give you this number). I have seen films/tv shows that have patches of hard telecining within progressive content. (Anime is notorious for variable frame rate).
This is a problem because mpeg can have variable frame rate, AVI content must have a constant frame rate.
Using honor pulldown flags will make avisynth (or whatever) generate 29.97 interlaced video adding soft telecining in progressive areas and leaving hard telecined areas alone.
From 100% telecined you can then use an IVTC filter like telecide/decimate which will restore progressive frames from material that is soft telecined during playback.
Mind you, that still assumes that the interlaced portions are film sourced. They can just as well be true video (59.94 unique fields) in which case you will need to deinterlace to 29.97p or use something like AnimeIVTC().
Or to rip off Doom9: FORCE FILM WHEN YOU CAN, IVTC WHEN YOU CAN'T FORCE FILM, AND DEINTERLACE WHEN YOU CAN'T DO EITHER.
http://www.doom9.org/ivtc-tut.htm has more info for those looking to read up. It refers to DVD2AVI but that's pretty much the same as DGIndex (which is build from it).
