Check it out here.

Links are good for 7 days.

The audio is from the laserdisc and the ld video is on the left with bd on the right.

Can anybody make heads or tails of what’s happened here? The opening credits also don’t match up very well although they are very close. The criterion ld also has cue marks here and there btw.

EDIT: I can’t tell for sure yet but I popped in the blu-ray and it isn’t sped up so it seems dgavcindex did some funky stuff while parsing? I believe I had honor pulldown flags checked. Maybe I should just use force film or something?

EDIT2: Well, it’s got to be directshowsource or dgavcindex messing it up or something. I can get it to slow down to the right speed but the frames are duplicates instead of progressive like on the LD. I guess the BD is maybe encoded with vfr for some scenes. In any case those frames should be progressive and not duplicates so I still haven’t quite figured out what I’m doing wrong. Or there is still a chance that the BD is messed up and missing those frames. Is there a bulletproof way to take the vc-1 file from the bd and import it into avisynth with the correct frame structure? Right now I ripped the BD with makemkv then converted the vc-1 to huffyuv/avi with avidemux and then load it with avisource in avisynth. I first tried directshowsource with convertfps=true but this was the method used in the video posted up above. I’m tired of messing with it today so I’ll do some googling and try it again tomorrow perhaps.

EDIT 3: Bam! I think I solved my problem. Sorry for all of the updates. I don’t often rip BD’s and this is the first vfr/vc-1 disc I’ve had to deal with. The problem is that you have to tell directshowsource how many fps and to convertfps so the line to load the file would be like this:

DirectShowSource(“X:\Movies\2001 ASO-BD\2001-ASO-BD.mkv”,fps=23.976,audio=false,convertfps=true)

Everything seems to be progressive now although the criterion LD does still have a few extra frames here and there. It should be a bit easier to sync things up now. I’ll post the sync’ed LD to the spleen when I’m finished.
