[RESOLVED] DGMPGDec vs DGDecodeNV

Hello.
I have a question.
For VOB DVDs i use DGMPGDec like this (Decode using IDCT IEEE-1180 Reference) :
MPEG2Source("File.d2v",idct=5,upConv=0)
If i use DGDecodeNV with following command
DGMultiSource("File.dgi",i420=false,deinterlace=0,use_D3D=false,fieldop=0)
Will the quality result be the same ? (IDCT IEEE-1180 Reference).

Thanks.

Yes, there will be no perceptible difference in quality.

Of course, you can use Subtract() in conjunction with Levels() to visualize any differences.

There is one feature from DGMPGDec that I miss, the option info=3. It was very useful when used with colormatrix. Is there a possibility that this feature could be added to DGDecodeNV.

I agree with lych, I use ColorMatrix all the time with my mpeg2 footage, so "info=3" would be a nice feature in DGDecodeNV.

Thank you very much, admin.
I just tested DGDecNV 2032 with ColorMatrix(hints=true) and it seems to work very well.
