Deoldify Vapoursynth filter

Another good news.

I was finally able to properly calculate the average of frame using Vapoursynth, with this code

def clip_color_stabilizer(clip: vs.VideoNode = None, nframes: int = 5, smooth_type: int = 0) -> vs.VideoNode:
    max_frames = max(1, min(nframes, 31))
    def smooth_frame(n, f, clip_base: vs.VideoNode = None, max_frames: int = 3):
        f_out = f.copy()
        if n < max_frames:
            return f_out
        img_f = list()
        img_f.append(frame_to_image(f))
        for i in range(1, max_frames):       
            img_f.append(frame_to_image(clip_base.get_frame(n-i)))
        img_m = color_temporal_stabilizer(img_f, max_frames)
        return image_to_frame(img_m, f_out)   
    clip = clip.std.ModifyFrame(clips=[clip], selector=partial(smooth_frame, clip_base=clip, max_frames=max_frames))
    return clip

I calculated the images using 4 frames, this average should be equivalent to a "left" average using 7 frames.

Here the comparison: https://imgsli.com/MjQ5MTQ2

The average improved.
