Andrea, These were all looked at around July/August 2016 and I know for a fact that: http://renomath.org/video/linux/dv/chroma.html was incorporated as stated in the Release Notes for July 2016:
Chroma bug yuv420p interlace colormodel fix for DVDs via additional option “dvd yuv420.”
Release Notes for August 2016:
Additional plugin, yuv411, that performs interpolation and inpainting for DV source improved chroma upsampling results (courtesy Eric Olson website as pointed out by Igor_Ubuntu). It also has an additional setting called offset which shifts the chroma planes to the right by one or two pixels (set to 0 for DV source downloaded from a camcorder and set to 1 for a DV file encoded by ffmpeg). Works with the YUV-8 Bit or YUVA-8 Bit color models in Cinelerra but not with any of the RGB color models. Improved upsampling of the chroma planes helps with the 4:1:1 to 4:2:0 color space conversion needed to create DVD compliant mpeg2 video streams. You will not get any improvements if the project is being rendered back to DV format.

So many interesting tutorials on the site you pointed out! Thank you. I'll highlight a few pages. I guess these patches, in CinGG, are useless: http://renomath.org/video/linux/cinelerra/ http://renomath.org/video/linux/interlace/cinelerra.html (color space conversion) http://renomath.org/video/linux/dv/chroma.html There is also a collection of scripts: http://renomath.org/video/linux/bin/ -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
