AutoCrop for VS

[Infiziert90]

Hi,

I wrote a little auto crop plugin that allows you to crop stuff without knowing the crop parameters.
This is especially useful for videos with varying border sizes that need different crop parameters for every scene.
Please note that the filter output will not have a constant size and may need to be resized.

Release (https://github.com/Infiziert90/vapoursynth-autocrop/releases)

Still Work in Progress, but it should run without problems for 8-16 Bit and 4:2:0 + 4:4:4 subsampling.

I tried it with an old DVD with crazy boder sizes sometimes 30px (wtf). It seems to work, but it always leaves some borders, so it's never really completely cropped. sometimes ~4px are left sometimes ~2px.
But I guess this is also because the border is not "sharp" but fades out into black

Rise black level. Parts of these borders won't be probably pure black at all.

Hmm ... did you change the default color+color_second?

ps. Can you upload a picture from the original scene?

[ChaosKing]

yes, I tried that with different values. But I don't know what color format this is. I tried RGB values from photoshop color picker.

YUV ... you can get that color values from vapoursynth editor with color picker

Thx, but I still see some borders. And the cropping is not stable especially on camera pans and zooms.
