AVISynth script question

[8th-ShichinintaiDEL]

I have an .avi file exported from Adobe Premiere Pro 7, and am trying to compress by converting to .mpg with AVISynth and TMPGEnc as explained in the "mpegforcons" guide.

I'm having problems with the AVISynth, written in notepad, titled "MyFirstAttempt.avs". I've narrowed it down to this line:

AVISource(C:\AMV\testing.avi)

I get the error, "Script error: expected a , or ) (C;\AMV\MyFirstAttempt.avs, line 1, column 12)

Did I install AVISynth wrong, or do I have some blaringly obvious typo?

you need to surround the filepath in double quotes
AVISource("C:\AMV\testing.avi")
^like that

When I put quotes, it gives me the error:
"AVISource: couldn't locate a decompressor for fourcc"

Very common errror, the solution is dont use avisource.

Use:
DirectShowSource("footage")

^ that works for almost any file you throw at it XD, avisource is very selective. (In my tests, both have equal quality... anyone wanna say why avisource exists?)

It means you're missing a VFW codec. What FourCC did it tell you?

When I use DirectShowSource("footage"), most of the video works, except the first 15 seconds. My video's first 15 seconds are similar to a slide show, and the media player speeds through it in about 3 seconds (i.e. as if someone were running through a slide show without waiting to read any one slide). The rest of the video and audio are thus out of sinc by ~12 seconds, but besides that, it appears to be okay.

Do I need a leader to fix this?

I do not know what a VFW codec is, and all it told me was what I wrote.
Is a VFW codec a codec for AVISynth?


Thx for the help btw, I appreciate it.

DirectShowSource is known to cause improper synch sometimes.

Since you say you exported from APP (What's 7.0? The most recent version is 2.0!), the chances are high that you did export it as DV-AVI. That's bad, since it is an additional compression step. Go back, change the export settings and export is as uncompressed AVI. Then you will have no problems with AviSource, and the quality is kept. But be prepared, the file will be as 10 times as large. Or export is as HuffYUV or Lagarith, if you have any of this codecs installed. So the files become smaller.

VFW just stands for <s>Veterans of Foreign Wars</s> Video for Windows, and it's the kind of codec that VirtualDub(/Mod) requires in order to open a video file. Most codecs install as VFW, but some install as DirectShow only, which means VirtualDub(/Mod) can't use them (but your media players still can).

What codec did you use for <b>testing.avi</b>?

Adobe Premier Pro 7 = Adobe Premier Pro 1.0 (7); my computer can't handle 2.0.

I checked, and I exported as DV (NTSC), default for APP. I will look into getting APP 1 to export as HuffYUV or Lagarith and get back to you guys.

Adobe Premier Pro 7 = the name the people who pirated Adobe Premier Pro 1.0 used before realizing Adobe changed the naming scheme.

fixed.
