Question What codec should I use?

I just encoded the Star Wars Gangsta Rap to an AVI, using Ulead. It is uncompressed - about 3GB. In VirtualDub, I used MS-MP4 and it was HORRIBLE quality. XviD leaves really grainy video and that awful DivX logo. What codec should I use to get the video less than 20 MB? (Audio isn't a problem, I can always do MP3 audio, not that big.)

i think somebody's told you at least once, there is no logo on the actual video-- its just there because divx decodes the video & you've left the option to display it enabled. turn it of in start-->program files-->divx-->decoder configuration-->toolbar-->"show watermark", the logo won't show up anymore. or better yet, just install ffdshow

encode to xvid, get latest stable build (1.1) from http://www.koepi.org

use the settings outlined in this post http://forum.digital-digest.com/show...702#post343702

use the built-in bitrate calculator to get it to 20mb, and make sure the resolution is decent for the bitrate

Thanks, and no I was not told that before. I will try that out and see what happens. As far as FFDSHOW, I didn't install it because I had all the codecs necessary to play the files on my hard drive, and I do not encode much, this is one of the few times that I am. (Normally I use WMV and Ulead takes care of that)

make sure that in the first & second pass the directory to the stats file is the same. eg c:\pass.stats

click the 'more' button next to 'encoding type' to pick the directory.

Default is to save to the root of the drive. Sounds like maybe you are trying to run the 2nd pass without running the 1st first.

Yes. I said 2-pass (pass 2). Why, do I need to do 1 pass than do it again?

i assumed you knew what 2-pass encoding is

single-pass encoding is where the video is encoded immediately, at a constant bitrate. the quality sucks, unless your bitrate is very high

2-pass encoding (vbr) is much better. the first pass just analyzes the video, much like dvdshrink's deep analysis. vdub will not output any video, just a STATS file which will be used in the second pass. the second pass reads the stats file, and tells vdub/xvid where to apply higher bitrate. the second pass outputs the video.

do the first pass, then second pass. do not change any xvid codec settings between passes.

You want to know why 2 pass requires 2 passes?

Actually 1 pass using a fixed quant will give you perfect quality given a suitably low quant. No filesize prediction though. When targeting a certain size though, 2 pass is the way to go.

There are some settings you can change, like VHQ = 1 for the 1st pass and VHQ = 4 for the second.

If only there were a one-click app like Auto Gordian Knot for VDub

Pretty sure that AutoGK uses VirtualDubMod for encoding. So AutoGK is a one-click app like AutoGK for VDub.

Does it work?

Would it be as good as if I did it manually?
