List of command-line and batch utilities for AVISynth (and a few discussions)

I collated this for my own purposes but it might prove useful to someone else...

Thanks very much. I much prefer command line apps

Here is yet another thread about generating multiple AVS files from a directory list:
http://forum.doom9.org/showthread.php?p=520674

[Wilbert]

Thx for the list! I will clean it up one day, and perhaps merge it into one of the other stickies.

[mg262]

I'm flattered but if I had thought it might become a sticky I would have taken a lot more care over it! Please do feel free to change/move it however you like. I don't want to fiddle with it now that it sticky, but there are couple of things worth noting:

- The one I unhhelpfully labelled "(notes on command prompt)" is the one @stickboy refers to, and it's about using the command prompt to generate multiple .AVSs.

- In thread number 73709 someone asks about batch encoding .AVS files to .MP2, but it's really a TMpgEnc answer rather than a AVISynth one, so I'm not sure how relevant it is to this list.

OTOH there are some batch/commandline operations that aren't to do with AVISynth but would be used repeatedly with it. I have just looked up/got to work the command line syntax for getting VirtualDub to run AVS->AVI. (It allows you to run a batch job with each instance loading a new copy of VirtualDub, which is useful for filters which don't like VirtualDub's own batch mode.) So I might dump something on that into a separate thread if it sounds useful...

I've updated the batch page at http://www.blainehelmick.com/AVS2DVD/ to include the newst version 0.61 of QuENC and subsequently removed several apps that QuENC now replaces.

[Yuri Khan]

Why don’t you include the thread on xvid_encraw_avs?

[Moitah]

How about AVSAmp?

[Fizick]

Recently I found (rather old) AVS2AVI Wrapper v0.3, by HMage.
http://hmd.c58.ru/files.html
It creates fake avi like VFAPI, MakeAvis.
The name is the the same as AVS2AVI by Moitah, but it is other program

It is probably off-topic here, but where to i must post it?

[mg262]

You could ask Wilbert to assimilate it into the appropriate FAQ?

[Wilbert]

I will do that one day

Avi2swf.exe from SWFTools will convert avs files into flash swf files. Everything works well as long as the avs files are with out sound, but with sound it generates a working file(with sound), but produces an error in the end of the file and hangs. I dunno what is causing this?

Get avi2swf from here:www.swftools.org

On avi2swf.exe: avi2swf

WAVI - save WAV from AVI/AVS
http://sourceforge.net/projects/wavi-avi2wav

(Different from AVS2WAV)

I use a batch file with this to make AC3 at 128kb:

@echo avs2ac3 avsfile.avs
@echo audio from avs files and convert to AC3
@echo uses wavi and ffmpeg

@if %1X==X goto ALL

:LOOP
for %%I in (%1) do (
wavi %%I %%~nI.wav
p:\ffmpeggui\ffmpeg -i %%~nI.wav  -ab 128 -ar 48000 -ac 2 -acodec ac3 -y %%~nI.ac3
del %%~nI.wav
)

SHIFT
@if %1X==X goto END
@goto LOOP

:ALL
for %%I in (*.avs) do (
wavi %%I %%~nI.wav
p:\ffmpeggui\ffmpeg -i %%~nI.wav  -ab 128 -ar 48000 -ac 2 -acodec ac3 -y %%~nI.ac3
del %%~nI.wav
)

:END

Note the options for ffmpeg depend on which version you use.
The version I use came with ffmpeggui.

You don't need intermediate wav files if you 'pipe' the wavi stdout to stdin aften encoder:

wavi x.avs - | aften - x.ac3

Thanks, obviously much simpler.

I looked at the docs for ffmpeg and couldn't see if it accepted std input, though there probably is a way.

And fast, you don't need write to disk the big wav files.

To encode ac3 Aften, by Justin Ruggles (Justin also maintain the ac3 part in ffmpeg), is more optimized and versatile (accept many more parameters).

Also ffmpeg problems solved with Aften:

- The multichannel encode (5.1) is wrong mapped with ffmpeg.
- The 32-float samples (a common format after audio process with AviSynth) are not supported by ffmpeg.

There are also many ffmpeg versions with different behaviour about STDIN and input parameters (-ab 192 / -ab 192000).

Hi all!
I have problem with wavi. My avi file is analog capture in VirtualDub 1.8.1 video huffyuv, audio PCM 48 kHz. I get error

F:\Video\Jakob>wavi film.avi film.wav
Found PCM audio: 2 channels, 48000 Hz, 16 bits, 5343.840000 seconds.
Writing WAV file "film.wav"...
Error: Could not read audio data from "film.avi".

In VirtualDub I can save wav file without problem.
Please advice.
yup.

Wavi only understands simple wave audio.

Most AVIs have some kind of compressed audio.

Normally use WAVI on an AVS script, then Avisynth will convert to wave audio which wavi can output or stream.

Assuming you have Avisynth installed,
Make an AVS, eg film.avs, in the same folder as film.avi, with one line:
AVISource("film.avi")

then run:
wavi film.avs film.wav

[yup]

AlanHK!

If using avs scrip all work fine.
yup.

Hi everybody, I'm new to this board.

I see the avs2avi wrapper has been mentioned in this thread, could anybody here please suggest how to modify the installation procedure (maybe the .inf) in order to have the codec successfully registered in Win x64 (XP or Vista)?

I found on the web quite simple instructions for installing VFAPI in Win x64 and they worked just fine.

I tried doing something similar for the avs2avi wrapper with no success (ok the contextual menu and wrapper avi generation, but apparently the codec doesn't get registered so no decompressor appears to be available).

Thanks a lot for any advice.
