The reasons I don't do it all the time, is simply because it adds at least 20 minutes to processing an avi, much longer if you spend a lot of time deleting bad frames in virtual dub.

Hi Mike - that would be my experience here too; what I'm thinking (out aloud here in this thread) is that where Virtual Dub adds the most value is in deleting the badly shape distorted but still contrasty frames that Registax would have let slip through. That would suggest that the value of virtual dub is in pre-filtering avis's taken through very poor seeing, but perhaps not worth the effort otherwise. I think my Virtual Dub pre-filtered image (attached again below) certainly shows more detail than my original and perhaps even Asi's reprocess of my un-virtual dubbed original - or maybe it's just more noisy giving the illusion of detail? - though I guess this is a very subjective thing.
cheers,
