In case you have not seen it, the replies to my related mail request on the old CinCVS mail list might have some more information: https://www.mail-archive.com/[email protected]/msg05573.html Yes, I see

this one not very encouraging:
====== Note that Cinelerra does two tasks: render and display.
To render, Cinelerra treats the 1440:1080 as square pixels. This is not optimal if something you render has both horizontal and vertical extent, but is driven by only one parameter, like the radius of the radial grandient, a radial blur, or the 'feather' radius of the masks. Such things will turn into ellipses because:
To display, Cinelerra simply stretches the available pixels to 16:9 ratio.

this question of you was left w/o answer, at least it was off-thread. https://www.mail-archive.com/cinelerra%40skolelinux.no/msg05586.html
====== For captured HDV and SD DV footages it looks like Cinelerra automatically takes care of scaling. What doesn't look quite clear for me yet, is what has to be done in Cinelerra for in cam downconverted HDV to anamorphic DV? =======
I'll use search and try to read code a bit more.
I think I found manual on how to mix DV and HDV in same project in Cinelerra, but it was involving manual scaling?

ah, no, it has no specific mention of HDV in this section, but our problem is indeed those non-square pixels, and how to paint over them .... I found another, related mail thread (2016): [CinCV TNG] Create 16x9 video from 4x3 sources https://lists.cinelerra-cv.org/pipermail/cinelerra/2016q2/004927.html
Thanks, according to this thread same DVD disk may look different on different players/TV/monitors ... My friend said some of those display devices may have their own fine controls for scaling (on-screen menu?).
But I only have this monitor (1440x900 it says IPS LED LG on front and "Manufacturer: GSM Model: 5b01 Serial#: 5886" in X.log) as my viewing device (I have older CRT monitors, Samsung SyncMaster 550b, but for now I prefer not to unplug vga cable too much - it sometimes loose red and blue signals, so I prefer not to strain it more)
Ok I happend to search yet a couple of related mail topics from the past CinCVS, and complement them here as references: [CinCVS] 16:9 from 4:3 ?? https://cinelerra.skolelinux.narkive.com/modLKoWa/cincvs-16-9-from-4-3 [CinCVS] Compositor stretching 16:9 https://cinelerra.skolelinux.narkive.com/kkJef8tW/cincvs-compositor-stretchi...
