Slow, slow(!) render rate in VirtualDubMod

Postby manpurse » Fri May 11, 2007 9:09 am

OK, I've ripped my DVD, the footage looks pretty good, and I'm ready to edit. But first, I have to change my .avs file to an .avi file. No problem!

...

Well, actually, there's a problem. No matter what codec I use, I can't get VirtualDub to render faster than 0.0-1.0 frames per second. I've never had this problem before. I tried an MJPEG codec, Huffy, Laga, "FastCodec"--even DivX and XviD! I <i>know</i> that I've done episode-length DivX conversions in about an hour before.

My current screen says that it will take about 48 days or so. Which, uh, is bad. I kind of wanted to whip something up in, say, the next week. (More specifically, by the 15th.)

Is there any way to get my video to render faster? What's the hold up? It's the hour-long FAKE OAV, if that helps.

I'm horribly confused.

what virtualdub and/or avs filters are you using?

Let's see...

I'm using deen, mtoon(?), and Tweak (I upped the saturation a tad). I also fiddled with the interlacing with Telecide and Decimate. I'm not sure if I kept in the "rainbow" filter.

I <i>think</i> that's everything.

Now my status box says it will take three days to render. Which is better, but any suggestions are welcome.

(I'm trying out FastCodec right now.)

you might also want to look into some alternatives to what your doing like just saving parts of the vid you want as oposed to the whole thing or frameserving/bait and switch method.

Dude, it was so mftoon's fault.

Thank you very much! :) The video quality's a tad less awesome, but now it will only take four hours to render.

It's amazing how much only little filter can wreak so much havoc.

I find vdub to be off in its estimation, too. I had one project say 30 days and it was done in 2.

/me can't wait for EADFAG mk III to become standard so that people won't see mfToon/vmToon as the first recommendation for sharpening and line enhancement and maybe so many people won't keep having this problem.

I think he means it being the main guide that is posted in the How-to Guides section, since the previous version is still the one up there

Not until the "beta" is gone from its URL, it's not. :P

I've dumped mftoon and never looked back. The results I get with FastLineDarken() and aWarpSharp() or LimitedSharpenFaster() are very similar (and if I take the time to tweak settings, almost indistinguishable), but the rendering speed is much faster.

If you use FastLineDarken() and aWarpSharp() together you'll probably want to set FastLineDarken's thinning parameter to 0.
Code: Select all
FastLineDarken(strength=90, thinning=0)
aWarpSharp()


Using FastLineDarken(strength=50, thinning=0) with aWarpSharp(depth=8) may give you better results since aWarpSharp() at the default settings (depth=16) can make some lines look weird.
