Avisynth/vdub - how to set a video codec for encoding

[pinkshiro]

Hi,

I'm slowly making my way through Avisynth, using vdub.exe (virtual dub) at a command line level to execute my script and generate a video.

However, I am stuck at how to select a codec to encode the video with during this process. Not sure if I am supposed to set it inside AviSynth or with a vdub command.

This is the command line code I am using for vdub at the moment:

vdub.exe /p example.avs example.avi

vdub.exe /r

If you want a command line- use a mencoder.

encoder_lagarith.cmd:
X:\System\Video\megui\tools\mencoder\mencoder.exe %1.avs -o %1.avi -nosound -ovc vfw -xvfwopts codec=lagarith.dll

run as: encoder_lagarith.cmd you_file

You can't normally select the codec in your Avisynth script (the only exception known to me is QTSource.dll, which can output to .mov while frameserving).
Your .avs will simply create a videostream and frameserve it to a requesting application.

I found to be the easiest way to batch encode with virtualdub is to use its "processing settings":

1.) Open VDub and load your .avs. Choose the settings you want (codec, filter, etc.).
Save these with [CRTL]+S or in the menu "File\Save processing settings".
This will give you a .vcf file.

2.) Use the commandline version of VDub with this .vcf file.
Example: "vdub.exe" /min /s "vdub_settings.vcf" /c /p "input.avs" "output.avi" /r /x

Good luck.

:thanks:

dr.schanker: That did the trick, thank you! I have a rudimentary VCF file setup and I see it is encoding with the set codec. Good one.

Vitaliy Gorbatenko: Thanks alot for that information. May be a better alternative to vdub if I run into any more brick walls.
