Hey, Wilbert - ColorMatrix for HC/ProCoder?

Hey, Wilbert, Will you help my poor, pitiful brain out (Ivo will agree with that) and tell me how/when to use ColorMatrix when the encoder is to be either HC or ProCoder? Is there a way to script such that the conversion is executed only if needed?

Encoding a clip with ProCoder and then opening the result in DGIndex says that it's rec.709 as well.

Maybe I could add a hidden setting that can be appended to every MPEG2Source() variable -- if not I could end up having a neverending feature overload... and most people would never use them. Something like: AddToMPEG2Source=", info=3"

Yeah, that would work. Maybe it would be more appropriate to have a string for the arguments with a default setting and make that something that isn't available in the GUI. I wonder if Donald has plans to put automagic coefficient conversion into DGDecode...

Just to note: this info-parameter is *only* needed for neuron2's builds. My build always outputs colorimetry-hints (needs no additional parameters whatsoever). Cheers, NaN

Good point, I'd forgotten about that. Unfortunately, your builds haven't worked with the difficult streams I've pulled from silver discs. IIRC, jdobbs used file length as the only way to automagically detect your builds and DG's builds.

Hi Boulder! Sorry for not responding to your problem - I was very busy lately. It would be great if you could do some tests, easiest would be to download DebugView from sysinternals.com, add the debug switch to ColorMatrix' parameters and have a look at its output. Just use Gspot or DGIndex to read colorimetry from the source, so you know what should happen. If hints are not detected, please ensure you're using my build called DGDecode 1.1.1 (from ). Cheers, NaN

@boulder With DGDecode 1.4.5 you MUST add info=3 to the MpegSource("..\...\myd2v.d2v,idct=6) line !!! And as for the second script , it could be ColorMatrix works only in YV12 (I don't remember well , but try to put the line just before the ConvertToYUY2() line ) ....

Trust me, I know what I'm doing ;) info=3 was there, I just forgot to mention it. And ColorMatrix does support YUY2 as well. If it didn't, it would complain about the colorspace instead of hints. As noted, resizing or colorspace conversion will lose the hints.

Yep, the problem seems to be that the hints are lost when you resize or convert the colorspace. Probably one for Don I think..
