Interlaced with XviD

[Jan Marijniszoon]

When I encode interlaced material with MPEG-2 or DivX 5 everything is OK.

But when I enable interlaced-mode in XviD and play back the clip later on, I get all strange kinds of artifacts.
I tried to leave out fancy options like VHQ; that helps a little.
But still some artifacts are remaining.

While decoding I tried both xvid and ffdshow.

How come?

when encoding with DivX, are you using a "1 click software" or AviSynth ?

with AviSynth, you should use a IVTC/deinterlacing filter, like Decomb.

I think "interlaced mode" in XviD is only worth without vertical resizing.

Sometimes there are good reasons to simply keep the stuff interlaced, e.g. pure video content for viewing on TV only.

From my experience, interlaced encoding together with B-frames is broken in the recent builds :(

Try without B-frames, and it should work correctly.

Yes the reason you bring up is exactly my reason too :-)

You are right! Without b-frames it works perfectly (even with VHQ-4).
Too bad that b-frames won't work in interlaced mode.
Any change that this issue will be fixed in the near future?

I sure hope so because most of my DVD's are interlaced (unfortunately) and I wanted to use XviD to do a HQ backup so I used VHQ4, B-Frames, Chroma, the lot... but ended up with a movie that was full of artifacts. It was kind of cool... IF I wanted to make the movie look like an MTV video clip! :p

So I had gone back to DivX5 but I'll give XviD another go then.
