Colorspace questions

[-Habanero-]

I'm trying to denoise this animated video with Neatvideo in interlaced mode before I run QTGMC but this is a problem because Neatvideo only works with RGB and converting back to YV12 later will screw up the chroma so I welcome any suggestions for workaround tricks.

I tried point resizing to double the resolution thinking this will override the 2x2 chroma limitation of YV12 but it STILL smeared the chroma for some reason. Either way, QTGMC doesn't work with YV24 despite saying it does and doesn't wanna work with RGB32 because of "scene change" incompatibility.

This video is from a DVD and its native colorspace is YV12.

ConvertToRGB(interlaced=true)

ConvertToYV12(interlaced=true)

That worked, thanks.

You need to ConvertToRGB(interlaced=true) when feeding VirtualDub. Then convert back to YV12 with ConvertToYV12(interlaced=true) before QTGMC. Do not let VirtualDub convert to or from interlaced YV12. It doesn't understand interlaced YV12 and treats it as progressive, blending the colors of the two fields together.

That makes sense. I'll never trust virtualdub to internally handle colorspace anymore. I've done hundreds of encodes over the years before I found the cause of all the colorbleeding I'm now stuck with.
