I'm going to make a bunch of educated guesses based on your description

The shifting of colors is likely Rec601 vs. 709 mismatch. How the YUV video is converted to RGB for preview. Vdub/vdub2 uses rec601 by default, which is usually incorrect for "HD" sources .

Not sure what the flickering is by the description (can't see the images, and you can't see flicker on a single image anyways....), but vdub/vdub2 also upsamples the chroma and convert to RGB in a progressive fashion, so if camera recording was interlaced, you will get chroma artifacts in the preview

In order to use a RGB filter (such as deshaker) when you have interlaced input, you would normally double rate deinterlace first to 50p then use progressive conversion to RGB , also specifying 709 matrix (Most people would use QTGMC for general use) . Deshaker works better with progressive input. Resolve also works better with progressive input

Code:

LWLibavVideoSource("00186.mts")
AssumeTFF()
QTGMC()
ConvertToRGB24(matrix="rec709")
