    Hello. I have the following problem when trying to deinterlace an AVI file that I have digitized from a MiniDv camera using the WinDv program.

    Script Error

    MVTools: no BLITCHROMA function for block size 4x16
    (C:\Users\cohp\Downloads\StaxRip-v2.44.4-x64\Apps\Plugins\AVS\QTGMC\QTGMC.avsi, line 645)
    (C:\Users\cohp\Videos\Video 1.avi_temp\Video 1.avs, line 26)

    Hello, i'm having a similar issue and what I could find was this:

    Q: I am getting the error message "MV tools: no BlitChroma function for block size 4x16".
    A: You are trying to process interlaced footage without activating of the deinterlacing first (toggle it on in the 'avs\pre-proc.txt')
    By default deinterlacing is 'ON' only for DV sources (which are YUV 4:1:1, SD resolution)

    If it makes sense to you or you fixed doing something different please let me know
