DV decoder differences

Fichtre ! (as we say in french), astonishing ! It's a long time since i havn't checked that chain link, and i thought i was OK using mainconcept... As i want to test that, perhaps you could you help me: The DV compression is done by the camcorder, and OHCI capturing is just a file transfert. So can i change my captured avi files from one coded to an other, without re-writing or re-capturing ? (tests purpose, as i can't recapture right now). .

Thank you for your quick answer. i'll do some testing this WE. I just made some research and found here : the (free) tool to convert the streams. It rewrites the avi, but i suspect it is not necessary as you state; changing "dvsd" to "CDVC" in the avi header makes it seen as "canopus software DV" in the file properties box. How can i be sure that when outputed to the screen, the avi is really uncompressed by canopus? .

First thing: amazing! Thanks! Second thing: How can I prevent MS decoder from being used? bira

What I've seen is that VirtualDub can not call/see the Microsoft codec because VirtualDub uses vfw rather than wdm screen drivers. I have another programme called Multiquence which will see the Microsoft wdm based codec and use it. It turns out that Ulead's Video Studio also uses the MS codec. Mainconcept's codec is vfw based. So as long as you are using VirtualDub, you will not have to deal with the MS codec. But if you decide to used Graphedit, then you can and wil end up calling the MS codec.

I guess the MS codec will be used if you frameserver through AviSynth using the "DirectShowSource" command. bb

DV Codec Swap 

This VC Codec swapper? A great find! Thank you.

While I am not 100% sure on this, but I remember reading about DV codecs and that Mainconcept and Canopus are different but Sony/Panasonic/Microsoft were actually the same. They differ by nothing that affects output, they put out the same output (S/P/M), while Canopus and Mainconcept do something else to quality. If anyone knows more or heard of this, more info would be nice (besides what ScrollLock has mentioned from experience, I mean more of a technical side of it).

Nice thread ScrollLock - ever done any tests with Fast's DV codec? (this is used in Pinnacle Edition, because the program is actually Fast DV Studio) Canopus attempted to do a demolition job on the competitions' hardware cards by illustrating generational codec losses, BTW. Arky ;o)
