Maybe 10 is a bit too strong. I'll reduce it in the next version.

I slipstreamed 1.11 to reduce default hue to 5. Hopefully, you can live with that. I do think this hue correction is a good thing. If you can show otherwise, please do.

Hi, Donald!
Please give recommendations, how to select the parameter "Prefetch"? What does this parameter affect? Thank's.

It's an Avisynth+ thing that you can google. There are so many variables affecting it that your best bet is to use Avsmeter to time your script and empirically determine the best value. For some scripts, any prefetch reduces performance.

Hello :-) Which version of Dgsource (dgdecnv) has parameter "fulldepth"? I use 2053, checked others :-( There's no in manual either.

All versions of DGDecodeNV, for the last great while at least, have the fulldepth instruction
From the manual
fulldepth: true/false (default: false)

When fulldepth=true and the encoded video is HEVC 10-bit or 12-bit, then DGSource() delivers 16-bit data to Avisynth with the unused lower bits zeroed. The reported pixel format is CS_YUV420P16. If either of the two conditions are not met, then DGSource() delivers 8-bit YV12 or I420 data, as determined by the i420 parameter. When fulldepth=false and the video is HEVC 10-bit or 12-bit, then the video is dithered down to 8-bit for delivery. If you need a reduced color space (less than 16 bits) for your high-bit-depth processing, you can use ConvertBits() as needed after your DGSource() call.

I try to use it in Avspmod 2.5.1 and get a script error: dgsource does not have a named argument "fulldepth". :-(

Your version is too old, update dgdecodenv.dll.

Thanks! I've been using first 2053 version :facepalm: Now it works great.
