It's a 1080p Blu-Ray remux, so what do I do to fix it?

Depends on your goal and your methods...

Avisynth has functions to convert between YUV and RGB with different matrices. So at least you could use that to test which conversion matrix fits your needs. And then ... well, maybe a special tool can patch the video stream to add colorimetry metadata.

But that is already way beyond the purpose of VirtualDub2.

Here's a sample.

[v0lt]

Method of correcting parameters for BT.709:

ffmpeg -i "Blu-Ray Remux Sample.mkv" -map 0 -c copy -bsf:v h264_metadata=colour_primaries=1:transfer_characteristics=1:matrix_coefficients=1 "Blu-Ray Remux Sample_fix.mkv"

It worked! Now how do I do this in VirtualDub2?

Also, another problem that the both and new samples produced this glitched image. How do I fix that?

There is no such functionality. You want too much from VirtualDub and do not understand for what purposes it was made.

[poisondeathray]

When video is unflagged, vdub2 assumes Rec 601 for the RGB conversion. Usually this will be wrong for most HD video

A workaround in vdub2 would be, video => filters => alias format => color space Rec.709

Why so? In VDub in Video->Decode Format you can change from 601 to 709. Even set 709 as default.

[jay123210599]

Both solutions worked, but what about my other problem with the faulty image?

Yes decode format works and is a better workaround

I don't see the faulty image in vdub2 with your sample video. How did you produce the problem ?

Never mind, I went the program again and it didn't show up, must have had to restart the tool.

[jay123210599]

Is there a filter for VirtualDub2 that allows you to burn in PGS (.sup) subtitles?

[LigH]

There is one for AviSynth: SupTitle

Unflagged video? What does that mean?

[LigH]

"Unflagged" = The video stream contains no set of bits (= bitflag) describing some of its attributes, here its colorimetry.

[jay123210599]

I want to use ffmpeg as an external encoder to extract frames and make image sequences, and also burn in subtitles. How do I do that while replacing it with the default encoder?

and the rest of the my question? to extract frames and make image sequences, and also burn in subtitles?
