If you don't know what AVISynth is, you haven't read the guides properly. Go read them again, they explain all this.

I'v read up on Footage Preparation & AVIsynth in your sig along with the whole rest of the thing and now that Quote: "my large intestine has leaped straight up through my neck and throttled my brain in an attempt to save my own sanity" I don't see how that sloved my instalation problem.

I learned a hell of alot about AVISynth though ^_^

Just get Windows Media 9 Encoder

Now when you final export your project, use a lossless like HuffYUV.

Make sure you've got the Directshow for huffy.

Encode to Windows Media 9 Professional using the Encoder.
If it doesn't take, use AVISynth to do "DirectShowSource" it. Changing to uncompressed AVI doesn't give any loss and allows you to encode it realtime without reencoding to AVI first.

Doing this the AVISynth way? Prepare for a long wait.

Do this before watering the lawn, washing the dishes, lunch, end of the world, ragnarok, etc.

The last one is preferable, it takes on average 15-20 years*
*On my 38Mhz 16MB RAM IBM Aptiva computer; I DO use it all the time! For controlling the Christmas lights :)

I'm not saying I support using WMV for AMVs, but how do you get WME9 to even take AVISynth scripts? Is there some kind of plug-in you need?, 'cause I tried it before and it didn't work.

I'm sorry to keep bringing this up, but how come I can't open AVISynth at all? All I need to know is what type of file to download and how to install.

Thx for your help ^_^

I don't know if this was explicitly stated before, but: <i>you don't "open" AVISynth.</i>

You write scripts in Notepad, give them the file extension .AVS, and open those scripts in other programs. AVISynth is what turns those scripts into something those programs can work with; it does all its work behind the scenes, if you will.

Hey,

Ok, thats easy as hell but those are just scripts. When I export my vid can I give an AVS extantion?

No no, you export the video with an AVI extention like you usually would, then you write an AVISynth script for it and put the AVS extension on <i>that</i>... here's an example from my own hard drive:

AVISource("C:\Adobe Premiere 5.1\Projects\<a href="http://www.animemusicvideos.org/members ... Maudio.avi")
BilinearResize(320,240)
AssumeFPS(23.976,true)

The first line calls up the video I exported from Premiere, with (as the name implies) HuffYUV video and PCM (uncompressed) audio.
The second line resizes the video down to 320x240.
The third decreases the frame rate from 24 to 23.976 and changes the audio's sample rate so that it syncs.

So the video I exported from Premiere 5.1 was 640x480 at 24 FPS.
When I feed this script into VirtualDubMod, what VirtualDubMod sees is a video that's 320x240 at 23.976 FPS.

Get it?

Yea I think I do. So in notepad, on the first line, I write the source it's comin from, a lossless codec (huffyuv), and it's location. Second line I resize the vid. And third line I decrease the frame rate. Then I give it an AVS extention, and open it in Vdub. Right?
