Technical question concerning VOB's

Sarcastic Assassin · Post by **Sarcastic Assassin** » Thu Mar 18, 2004 10:50 pm

Specifically, what are VOB's? (those voluminous and strange files produced by DVDDecrypter in IFO mode) If need be, could one simply rip the VOB's from a DVD, and use them as source footage? (as opposed to using the DVD)

The only reason I ask is because I have a fairly ardent anime fan for a friend, who I frequently borrow anime DVD's from.

VOBs are an acronym for Video OBject. They are a container for MPEG-2 video streams, audio streams in various formats (usually Dolby AC3, DTS, or linear PCM) and subtitle streams.

VOBs can be used for AMV creation and in fact are probably the dominant medium that AMV creators use for sources. Look here.

Maybe so, but if you do then you're most likely importing it interlaced, which is very very bad...

Absolutely. Temporal Softening is a lifesaver!

On the topic of interlaced, whats a good AVS command to deinterlace PAL footage, that wont change the framerate as IVTCing does to NTSC footage?

Would just Telecide() do it? That worked for a pure 29.97 HuffYUV for me...

PAL is at 25fps. He doesn't want to change the framerate so IVTC won't work in this case. I don't work with PAL so I have no idea. Check the Doom9 forums. They will probally be much more help than we will here.

I know, that's why I said Telecide() without Decimate().

I ran a Telecide() only on a pure 29.97 clip, and it deinterlaced it without changing the frame rate, is what I meant to say.
