[HELP] ReplaceSingle (to replace multi)

[Selur]

Do:

# replaces frame x +1 with a duplicate of x
def duplicate(clip: vs.VideoNode, x: int) -> vs.VideoNode:
    part1 = core.std.Trim(clip, 0, x)          # Frames 0 to x (inclusive)
    replacement = core.std.Trim(clip, x, x)    # Only frame x (duplicate)
    part3 = core.std.Trim(clip, x + 2, None)   # Frames x+2 to end
    return core.std.Splice([part1, replacement, part3], mismatch=True)
return duplicate(clip, 7361)

is faster and works.
If you wanted to duplicate 7361 and 7447 you would use:

# replaces frame x +1 with a duplicate of x
def duplicate(clip: vs.VideoNode, x: int) -> vs.VideoNode:
    part1 = core.std.Trim(clip, 0, x)          # Frames 0 to x (inclusive)
    replacement = core.std.Trim(clip, x, x)    # Only frame x (duplicate)
    part3 = core.std.Trim(clip, x + 2, None)   # Frames x+2 to end
    return core.std.Splice([part1, replacement, part3], mismatch=True)
clip = duplicate(clip, 7361)
clip = duplicate(clip, 7447)
return clip
