Motion compensation does not work that way.
Thank you, Paul. Yes, I knew that. I'm not seeking motion compensation.
Kindly reread my filter
features and suggest what comes closest. What I seek simply works on
pixels. I'm relying on your
experience (and perhaps the experiences of others here).
Have you tried nnedi or estdif filters? Both are intra only
deinterlacers.
Thank you for the guidance. I'm trying estdif first because it seems
simpler, but it doesn't do the
good thing. It does decomb very effectively, but it does it by aligning
(shifting) the edges in
field'2' to the edges in field'1' (which are not shifted). Aligning with
field'1' produces judder
(or in my case, doesn't eliminate judder). What I want it to do is align
both field'1' edges and
field'2' edges to the median (i.e. half way between the input's edges). I
do realize that such a
method would introduce combing along the edges of the frame, but that's
okay.
Here's the command I used to transcode 24FPS to 60FPS:
ffmpeg -i 24[1][2].mkv -map 0 -filter_complex "telecine=pattern=5,
split[1][2],
[1]select=not(eq(mod(n\,5)\,2))[3], [2]select=eq(mod(n\,5)\,2),
estdif=mode=frame[4],
[3][4]interleave" -codec:v libx265 -x265-params "crf=16:qcomp=0.60"
-codec:a copy -codec:s copy
24[1][2]-to-60[1][1][estdif=mode=frame(1~2)][2][2].mkv
I'll try nnedi. Perhaps I can figure it out.
Do not even try.
Mentioned filters work only with interlaced frames, while your use case is
completely invalid and frowned upon.
I deeply regret replying to this thread.
Also, the only way to "invent" new frames is to use either motion
interpolation via optical flow or via blocks interpolation like with
minterpolate filter.
There was some reason why I didn't try minterpolate but I can't recall what it was. I will give it a
try. I assume I don't need to use '-filter_complex' or 'select'. Just something like '-vf
minterpolate=fps=60000/1001:mi_mode=blend' for the 1st try.
Do you have any insight about minterpolate you'd care to share?
Thanks,
Mark.
Thanks again,
Mark.
Regards,
Mark.

Hello All,
I seek a decomb filter that operates on H/2 number of line pairs:
lines
i
& i+1 (where i=0..H/2-1),
by aligning edges in the two lines at x = delta-x(edge)/2 (i.e. the
median). The ideal filter would
differentiate overall motion due to panning versus local motion due
to
local object motion.
Pan-combing on the left & right edges is acceptable but it would be a
great bonus if the filter
performed blend on those edges with the blending radius equal to
one-half
the pan-comb.
Vertical, line-pair-to-line-pair processing is not needed or desired.
Frame-to-frame processing is not needed or desired.
I have been trying a great number of filters based on their names and
what
is in the documentation.
The best I've found so far is pp=linblenddeint but it obviously
doesn't
align edges via the edge
median and it obviously isn't aware of pan-combing versus
object-motion-combing.
Any suggestions are very welcome. If I find this filter I will post a
link
to a 60FPS telecined
video that will amaze everyone -- better than anything that Cuda can
do.
-Mark.
