The MainConcept decoder does not have the chroma upsampling bug: In both RGB and YUV2 modes it uses a luminance range of 0-255. Unfortunately out of the 3 decoders it performs the most sharpening, which increases the noise level. The MainConcept decoder supports both YUV2 and RGB. Fortunately this bug can be fixed using AVISynth's function "FixBrokenChromaUpsampling". Watch out though, when the Canopus decoder performs the RGB conversion it seems to use a luminance range of 16-235 instead of 0-255 used normally for computers.Ī big issue with this decoder is that it has a nasty "chroma upsampling bug". ![]() Out of all DV codecs, the Canopus decoder does not seem to apply any sharpening of the decoded image (which is good in my opinion). ![]() ![]() This codec uses the FourCC "cdvc", so before the system will use it you have to change the FourCC of the AVI file with a tool like AviC supplied with the XviD codec (default FourCC for DV is "dvsd"). While I initially thought that they will all deliver the same result, I was surprised to find out that there is quite some significant difference between the decoders. ![]() Since I recently purchased a DV device, I played around with various DV decoders.
