Is it possible to disable the chroma "channel" or luma "channel" while deinterlacing a video file in Avisynth+ with Virtualdub2? Here's the script where I want to place the code (if possible):

LWLibavVideoSource("Mark Tape 2 - AV Box 76.mp4", cache=false)
AssumeTFF()
SelectEven()
QTGMC()

even = SelectEven()
odd = SelectOdd()
interp = even.FrameRateConverter().SelectOdd()
odd = MergeChroma(odd, interp)
fixed = Interleave(even, odd)

return(fixed)
