I give you: Offline AVS Renderer (Beta)

So, I don't know if this will be useful to anyone right now, but here it is anyway.

http://code.google.com/p/offline-avs/

So, basically, you can render giant 1080p and up AVS videos. Jheriko and I wrote it, with help from PAK-9 and grandchild.

This is a Windows command line app that runs AVS without Winamp. Slowly. Give it a render size, a source wave file, and a preset file, and Offline AVS will spit out a png for every frame.

But here's the difference: normally winamp keeps playing audio while AVS renders in its own thread. This syncs the audio stream with avs's frame rate, feeding in audio in 1/30th of a second chunks, regardless of avs's internal frame-rate.

What this means is that you can automatically render giant avs frames as an image sequence. Convert the image sequence to a movie at 30fps, and then lay the audio on top, and it'll be in perfect sync, regardless of the captured render size.

You run it like this:

code:
avs_rig.exe vis_avs.dll width height waveFile.wav presetFile.avs


You'll need something to combine the images into a movie file with the audio on top. I use After Effects. Just import the image sequence, add it to a new comp, and pop the source audio on top, and you're good to go.

Right now it only works with wave files, 44100Hz sample rate, 16 bit PCM. Stereo or mono, both work.

Hopefully by the end of the week I'll have a GUI frontend for it ready to go as well.

Here's a list of things that are good ideas to add but that I'm too lazy to actually add:
  • Support for MP3 / Other kinds of audio files
  • Automatic combination of image sequence and audio into movie file

This thing is still a beta so let me know if you witness any issues with it. If you want to add mp3 support or anything else, come find me on #avs on freenode irc network, and I'll give you commit access.
