For the record, the non-filter parts of the script are working fine - I can resize, change FPS, combine video, dub audio...everything but filter.

If all the processing was being done in AviSynth, then having VDub set on Direct Stream Copy would still net the result of the script (of course, it'd be horribly inefficient to do so since I believe it'd force a colorspace conversion not unlike Full Processing mode; at the very least you'd be getting Uncompressed YUV*). Or so I would think. As far as VDub should be concerned, the script - with whatever processing is in it - is all it sees. It wouldn't be able to omit AviSynth filters just because.mirkosp wrote:Direct Stream Copy wouldn't exactly work I guess, you should try fast recompress instead. Direct Stream copy just copies the stream so I guess it just copies the original video and not the filtered one...
