View Full Version : Advanced options not showing up in Vdub?

I've been using Xvid to do video encoding for a while, and it always works great. I usually use the ones from Koepi.org but now there's something wrong.

Not sure what happened... I had installed a new pack here that a friend recommended http://www.animemusicvideos.org/guides/avtech/amvapp.html but they screwed up and I had to uninstall- but it had the unfortunate side effect of uninstalling ALL my video codecs. So I had to reinstall Xvid, no biggie... I got the latest stable binary from Koepi and also reinstalled that pack and everything works now except...

But for some reason the 'Advanced Options' for Xvid in Virtualdub is gone. The button's just... not there anymore. I can't change Quantatization or anything, so I think it's stuck on the highest settings for everything and makes my encodes go twice as slow as they usually do. (Normally saving a 20 min AVI only takes 30-40 minutes on the first pass. Now it's taking over an hour.) I've uninstalled and reinstalled several times, with no luck.

Any idea what could be wrong? I just know it's never happened before...

Hehe, the reason is that the XviD interface has changed since the time you had your previous build. There is no Advanced Options button anymore. To get the Motion & Quantization tabs, click on more... next to the Quality Preset dropdown box near the bottom of the main dialog box. It will flash you a message about copying the preset values, press Yes and continue.

Oh thank you! I had no idea...

Hm, is Motion Search Precision normally set to 6? I'm doing cartoon stuff, do I need it that high? I set that lower and the encode is still going really slow... Is that because it's a new version of Xvid too? I mean my computer is still the same as always so...

Leave it at 6, cartoon or no cartoon. Your quality will degrade if you go lower, but most importantly, it shouldn't affect your elapsed time much. What is the VHQ mode? VHQ=4 is the slowest and VHQ=1 is the fastest, so if you have it at 4, then that would explain the slowness. Infact, VHQ is the single most thing which you can change, which will significantly influence the speed of encoding.

Well I always had it at 4 before, but the first pass (video only, no audio) still only took like 30 minutes, not an hour and 30.

I have all my settings exactly like I had before, so I can't figure out why it's taking nearly 3 times as long.

you probably had turbo enabled for the first pass.

Kindly please don't add extra confusion between "turbo" and "fast 1st pass".

In fact, there's already so much confusion about it that I'll need to rename BOTH, as soon as I feel like doing something :/

So your slowness is on the first pass? Then forget VHQ, because VHQ is disabled for the first pass. Neither is it Turbo, because Turbo has no effect on the first pass. First pass is already on a "kinda" Turbo mode because of faster ME calculations and whether you check or uncheck Turbo has no added effect.

My guess is that it could be the material, resolution chosen, filters used (if any) or something like that. Post your settings if you want, we can take a look to see if anything sticks out (but I doubt it, since your issue is with first pass; was it second pass, we'd have more to go with).

Well here's the AVISynth script I'm using, same as always...

Mpeg2Source("kirbyep27.d2v")
AC3Source("kirbyep27.ac3")

Telecide(order=1,guide=1,post=4,vthresh=50)
Decimate()

LanczosResize(640, 480)
Crop(4, 4, 632, 476)

Convolution3d(preset="animeHQ")
WarpSharp(30,60)

TextSub("lovelysub.ssa")


The source is DVD. I have all my settings exactly the same as I ever had them, so it makes no sense for it to be faster then and slower now. Turbo is off.

I don't know if it's because of the newer version of AVISynth I got (2.5 instead of 2.0) or the newer version of Xvid, or something...
