Encoding problem-high speed video

suckafreemc · Post by **suckafreemc** » Mon Oct 31, 2005 1:25 am

Ok, I've been ripping dvd's with VicBond's guide and creating trailers and the like. These are mainstream dvd's like matrix, equilibrium, boondock saints, etc. In the past three that I've tried I created some of the same basic scripts following the guide as usual, but now when I encode it to avi; the avi seems to be at about 115% speed of the normal dvd footage. Anyone know a fix for this? Is it possible that another codec might be interfering with the encoding process to make the video speed up? Any help would be appreciated, thanks.

What info does DVD2AVI/DGIndex give about the video stream? (Framerate, FILM/NTSC/PAL, etc.?)

What AVISynth filters, if any, are you using? (Post your whole script.)

DVD2AVI for Amityville Horror

16:9
29.970 framerate
FILM-Progressive
FPS 49-50, but that might just be the preview I don't know.

and this would be my script

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\MPEG2Dec3.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll")
MPEG2Source("c:\amityville.d2v", idct=5, CPU=4, iPP=true)
Telecide(order=0)

There is something wrong with this:

29.970 framerate
FILM-Progressive

It's contradicting itself. Either it has 29.97 fps or it is FILM, which means 23.976 fps.
Since you say it's speed up, I think 23.976 fps is right. So add AssumeFPS(23.976) at the end of your script.

Actually, I don't think that's a contradiction; I think DVD2AVI applies 3:2 pulldown on the fly to 23.976 progressive streams by default (I'm going by my experiences with the the R2 End of Evangelion DVD, which was in fact 23.976 progressive (and totally gorgeous); popping open the <i>Hellboy</i> trailers confirms it).

Try saving the D2V file with "Force FILM" enabled (this turns off the pulldown) and commenting out the Telecide line in your script.

Oops, I overlooked telecide(). Of course, if it is FILM, you don't need it. Otherwise it'll mess up your footage. That "Force FILM" I had in my mind too, but I didn't remember where to set it.

Thx for the help, I'll try to make a new avi when I go to bed tonight with these changes.
