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
https://www.mail-archive.com/cinelerra%40skolelinux.no/msg05582.html
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.

======
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?
http://www.g-raffa.eu/Cinelerra/HOWTO/anamorphic.html#_how_to_add_16_9_anamorphic_footage_to_your_standard_4_3_project
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:
