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.
