View Full Version : 3 ideas about getting avisynth-videos into quicktime

Hello,

i am a Avid DV Xpress and Avid MC user and sometimes i want to import .avi's or .avs'. But Avid uses Quicktime for import, so you only can import a limited number of codecs. Would it not be nice if you could open avs-files in Quicktime then?

Here are my three ideas how it could be done (maybe...)

1. someone could code a Quicktime Component which can import .avs files directly (there is a sourceforge project with an ogg vorbis component...)

2. someone could code a device driver which emulates a hdd with a virtual uncompressed .avi or .mov file which can be opened directly in every program, even QT.

3. Quicktime itself has frameserver abilities (Reference Quicktime) maybe some could code a avisynth or vdub wrapper which emulates a quicktime frameserver.

I am not able to do one of these, so the only chance i have is to convince one of the "avisynth-gurus" to do it ;)
Or is it so hard to do it, or is it impossible in general?

hopefully,
hanfrunz

lol, I had to write a program for work that would take any AVI input and feed it into QuickTime, that would accept avs. Shame I cant release it :( Maybe ill try and re-write it for the community.
(weird thing is I couldn't get the MPEG-4 video codec to to work under Windows (thru the SDK, it works fine thru quicktime), same code worked fine on Mac OS X version.

For you though, its quite difficult for it to accept AVI/avs files directly because it doesn't use any Windows APIs. Writing a codec for it wouldn't be particulary difficult (the best code to work from would be VP3's plugin structure, from there the AVI API could be called)
