What's a good freeware program to convert AVS to video?

[jk318]

Is there a good freeware program that will convert AviSynth scripts to video?

I have created an script to play (or frameserve?) flash video as a DirectShow source:
DirectShowSource("C:\Documents and Settings\HP_Administrator\My Documents\Downloaded FLV\genesis_noreplyatall.flv",fps=29.97000002997,audio=true)

It plays fine in Windows Media Player.

I have tried MeGUI but it will not let me use the audio from the video. It makes me choose a seperate audio file.

Hi,
WinFF will do what you want. www.biggmatt.com

Thanks, that works great, although it's quite slow.

Is there a fast program that will convert directly from AVS to AVI?

VirtualDub. Speed will depend on the video encoder settings.

[jk318]

Thanks, both programs work great.

I figured out how to save the file as an AVI encoded with x264, so is there a fast way to convert that avi to mp4, since its already encoded?

I tried putting the AVI file in an empty file with mp4ui, but I got an error message:
Exception: MPEG-4 Internal
Reason: video compressor H264 not recognized

VirtualDub:

Video -> Fast Recompress
Video -> Compression... -> select codec and configure

For example, select the Divx codec, set Rate Control Mode to 1-pass Quality Based, Fixed Quantizer = 3. A bigger quantizer will get you a smaller file with less quality. A smaller quantizer will get you a bigger file with higher quality.

AviSynth will also give you uncompressed audio so you'll want to compress that too:

Audio -> Compression... -> select codec and settings

Say, MP3 at 192 kbps.

Thanks. (sorry I edited my post while you posted)

Is there a way to encode to AAC with VirtualDub or AviSynth? I could not find AAC in the list of audio compressions. I tried installing CoreAAC.

This script will convert avs to flv @ 320x240 (or whatever -change script to suit yourself.)

Requires Mencoder http://oss.netfarm.it/mplayer/builds/mencoder-p4-svn-23404.7z


(Right Click to Save)
avs-flv_mencoder_script.cmd

DaudioK will convert AVS files to AAC

I'm not sure if Nero Recode accepts AVS scripts but it's fast and can create MP4 files with h.264 (AVC) video and AAC audio.

It does the same thing when I choose other mpeg4 encoders (like MS mpeg4 v3)


Another question: Is there a way to register codecs (or whatever they are) so that they appear in the list under Audio > Compression... in VirtualDub? I tried downloading and registering coreaac.ax

Hi,
WinFF will go directly to H.264 with AAC Audio from your AVS, just pick either the H.264 *iPodLinux* or H.264 HQ, There currently isn't an H.264 HQ Widescreen preset but I could easily make one and post it on the WinFF forum if needed. Also regarding encoding speed, if you run a dual core processor you can enable multithread in the WinFF preferences and speed up encoding by about 30%.

Thanks GMaq, its much faster now.

Where can I find a list of commands for ffmpeg?

Hi Again,

This is where I started, like anything it's not too difficult once you get the hang of it, Here's the link:

Here is another specific to H.264: http://rob.opendot.cl/index.php/useful-stuff/x264-qualityspeed-guide/

Thanks again
