Hi, what is wrong with this command? It gives me this error Pad out is not connected to anything.

mpv --lavfi-complex="[vid1]split=3[unfiltered][denoised][mask];[mask]lutyuv=y=between(val\,0\,25)*maxval[mask];[denoised]atadenoise[denoised];[denoised][mask]mergeplanes=mapping=0x00010210:format=yuva420p[maskeddenoised];[unfiltered][maskeddenoised]overlay[out]" "trek.mkv"

Thank you :)

change ending [out] to [vo]

mpv --lavfi-complex="[vid1]split=3[unfiltered][denoised][mask];[mask]lutyuv=y=between(val\,0\,25)*maxval[mask];[denoised]atadenoise[denoised];[denoised][mask]mergeplanes=mapping=0x00010210:format=yuva420p[maskeddenoised];[unfiltered][maskeddenoised]overlay[vo]" "trek.mkv"
