QTOutput

what codec exactly? (a lot is supported in ffmpeg)

one of the avid codecs (compressed 3:1 in my case) in theory any program would do the job, as it is quicktime itself who does the coding. the problem is that using the plugin, i get an error message.

well, what can i say due to lack of info: good luck.

sorry for the misunderstanding, that's really the codec's name: Avid Meridian Compressed 3:1

ok, looks like not in ffmpeg.

You can use avisynth virtual file system (AVFS) to frameserve into Quicktime Pro on windows , so you can access any quicktime codecs you have installed. It creates a "dummy" AVI which can be opened in quicktime, but it has to be RGB32 data (Add ConvertToRGB32() to your script , if it's interlaced, use the switch +/- specify matrix)

actually I did use AVFS to feed my script into Avid, re-exporting afterwards to Quicktime... So thanks for pointing out the obvious to me, I had forgotten that QT also opens AVI...
