Correct Color Settings

[Bathrone]

Ive done a search, couldnt find anything.

Im using AVISynth + DGMPGDec to frameserve vobs to virtualdub. I note in the color depth options of the video pull down tab is decompressed format and output format to compressor/display.

Im confused as to what options are right. It defaults too:

Autoselect decompression format
24bit RGB (888) output format

Should these be changed?

I normally use:
loadplugin(".\dgdecode.dll")
mpeg2source(".\your_d2v.d2v")

Filling in correct file name and paths for avs file, then use fast recompress in v/dub.

Might post this ? in Avisynth usage section of forum -- get many more responses

Sorry Mic, maybe I wasnt clear mate. I mean the colour settings within VirtualDub. In the video pull down menu, is the colour options. There is a range of different settings that a user could specify to VirtualDUb. I dont understand the settings and have not found explanations in documentation.

"decompression format" is the decompression colorspace VirtualDub requests from the decoder. If you set it to RGB24 the decoder will output the decoded data as that, with YUY2 it will output YUY2, etc, etc. With "autoselect" it will let the decoder suggest a colorspace itself. For the output format this is the same, and it i guess its preferable you set it to "same as decompression format". Although, I believe right now VirtualDub will always try to find the "shortest" path (no colorspace conversions if not necessary).

If you are using AVIsynth and not any VirtualDub filters, it would be preferable to use Fast Recompress where none of this all matters.
