Recolorization of black and white frames
Hi there,
I'm newbie with AviSynth. I use AviSynth+ 64bit and AvsPmod 2.6.3.4. I'm looking to restore old VHS recordings where some frames are in black and white. Something similar to what's been done here: https://www.youtube.com/watch?v=iaUsvKDQycg I figured out how to do it with MergeChroma() : Code:
frame_number_with_good_colors = 128 good_frame= clip.Trim(frame_number_with_good_colors,1) # Apply MergeChroma for frames with bad chroma (AverageChromaU() < 120) # Apply MergeChroma for frames in black and white (vPlaneMedian() = 127 or 128) copy=clip chromed=MergeChroma(clip, good_frame) clip=ConditionalSelect(clip,"v_median=vPlaneMedian()"+chr(13) \ + "av_chromaU=AverageChromaU()"+chr(13) \ +"(v_median==128 || v_median==127)?1:(av_chromaU<120?1:0)", copy, chromed) To do this, I need to store the number of this correct frame, as it has to be reused until a new frame with correct colors is found. However, I can't store the current_frame value in a variable. Could you help me on this point? Also, I tried to write this value to a file: Code:
clip = clip.WriteFile("variable.txt", "current_frame") Quote:
NB: The video I'm working on (as a test basis) is this one: https://www.youtube.com/watch?v=rX0r6WbiutU |
