Some additional commentary:
2. Deinterlacing:
The input PAL DV source file is Interlaced, Bottom Field First
...
Why does deinterlacing with dvd default rendering (mpeg2enc) still come out
as Interlaced, but Top Field first?ffprobe -hide_banner dvd.m2v
I have been looking for any information on this and lots of testing. As far as I can tell, whenever you Render or DVD Render, it seems like the Interlace always comes out Top Field First. I have not found a way to get Bottom Field First but have not tried all render formats (which I will continue to look at). It may be that it only does Top Field First or Progressive. 3. Dvd Interlaced Chroma
With reference to the CinGG manual
https://cinelerra-gg.org/download/CinelerraGG_Manual/Dvd_Interlaced_Chroma.h... ... I can't find this option and is it relevant for DVD rendering?
This needs correction in the manual. (Hopefully you found it in the screencast Andrew mentioned). It is Settings->Preference, Interface tab, 4th box down in the Operation section. TO BE CONTINUED as time permits.
