I hope that I'm not starting this discussion all over again ... I have been supporting ImageMagick for years now, where there are also have no 'stable releases', and I understand that its developers just don't have the manpower to support these. ImageMagick does have version numbering, but the developers deploy a new version every two weeks or so, and I would not recommend using the newest one (which may have new bugs), unless you have a problem that you cannot solve with the version already installed.

This has nothing to do with keyframes; I'm not talking about stream copy. eg. -vf trim splits in the uncompressed domain (data is decoded to uncompressed frames) . If you need to you can split stages as lossless intermediates You cut on cadence boundaries of 24 frame cycles. 24p is evenly divisible into 120p (5x) . 60p takes every 2nd frame from that 120p result this is what you are doing with optical flow retiming, so every frame is evenly spaced in time. > Note: Whether the minterpolate filter drops 10 frames or 5 frames is the > subject of [FFmpeg-user] > minterpolate PTS v frame count weirdness. Not sure what this is referring to ? Any more details ? If you're getting PTS , frame count weirdness, split it out as lossless intermediates -- Sent from: http://ffmpeg-users.933282.n4.nabble.com/ ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Here are some test videos - https://www.mediafire.com/file/9inkxdvi8iuo5hi/interpolation_test_videos.zip/file I made a source video "interp_test_src.mp4" @23.976p which has simulated camera pan movement similar to Mark's example. "minterpolate_default.mp4" is the using the default settings . Similar artifacts along top and bottom of frame near the letterbox edge. Cropping and padding (both external to the filter) did not help much. Central portion along the windows have some bad areas in some frames too. Typical motion interpolation artifacts Test1_mvtools2 using typical settings (default blksize of 16) . Similar artifacts test2_mvtools2_nocrop_nopad has a blksize of 32, but no crop or pad internally. It's better in the central and top and bottom, but still some "edge dragging" artifacts Test2_mvtools2 has blksize of 32, is cropped and padded internally to improve motion vectors (this makes a difference along the frame borders along the letter box bars), then letterbox bars added back. This is much cleaner with only minor artifacting. This one would actually be usable by most people On this sequence, a larger blocksize of 32 helps with the central artifacts, and the and internal padding helps with frame edges for mvtools2. I suspect if minterpolate had options for larger blocksizes and internal padding it would improve too -- Sent from: http://ffmpeg-users.933282.n4.nabble.com/ ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

You can technically, but minterpolate is not very user friendly - It's too slow for real work and feedback, and you cannot keyframe the settings on different scenes very easily. It's barely usable unless you program your own GUI around libavfilter More settings would help too - maybe you can improve the filter. I'll post an example later similar to one posted by Mark, where it's "solvable" using other methods, but not using minterpolate.

The only thing that come to mind, is that version is old that it does not
have that specific filter.
Also note that those audio filters are not magic way to solve your problems
by putting them in filtergraph and forgetting about them next second.

Re: [FFmpeg-user] VOICE POST PRODUCTION IN ONE LINE
If you wish to have output from your service, you would need to check the
documentation of the library you are using to execute the shell command.
They often have the ability to capture stdout and stderr which is what you
need.
Often, these libraries may interpret shell commands in different ways and
so it may be parsing the ffmpeg command line (this is something to keep in
mind, not necessarily what is happening).
If you can run your command from the shell normally, there is likely
something in your service code which is causing it.

Re: [FFmpeg-user] VOICE POST PRODUCTION IN ONE LINE
Thanks,
is there a way to understand if ffmpeg has aborted the process?
I'm using a Linux version for an online service.
It would be nice to let ffmpeg write a log file when there is a problem
(process aborted)
How to do it?
Thanks.

Re: [FFmpeg-user] VOICE POST PRODUCTION IN ONE LINE
Hello,
anybody knows the reason why this command works.
$ffmpegCmd = "ffmpeg -i $fileOriginale -af
adeclick,afftdn=nr=80:nf=-20:nt=w:om=o,highpass=f=70,loudnorm=I=-16:TP=-1.5:LRA=14
$fileProcessato"; //Livella audio a R128
and this doesn't work.
$ffmpegCmd = "ffmpeg -i $fileOriginale -af
adeclick,deesser=i=1,afftdn=nr=80:nf=-20:nt=w:om=o,highpass=f=70,loudnorm=I=-16:TP=-1.5:LRA=14
$fileProcessato"; //Livella audio a R128
This creates an audio file of zero bytes, just the name.
The difference is that the last I've added deesser=i=1
Any ideas?
Thanks.

To be completely fair, that is actually in the docs, but it's not exactly on
the front page.
Good point.
It is at the very top of the output of "ffmpeg -h" though:
Hyper fast Audio and Video encoder
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options]
outfile}...
Getting help:
-h -- print basic options
-h long -- print more options
-h full -- print all options (including all format and codec specific
options, very long)
-h type=name -- print all options for the named
decoder/encoder/demuxer/muxer/filter/bsf/protocol
See man ffmpeg for detailed description of the options.
Or you just do "ffmpeg -h full" and go on a long search for an option.

"-h type=name -- print all options for the named

Try 'ffmpeg -h type=filter.
It fails. Why? Because "filter" is a "type", not a "name" -- never mind that the details says "...
named decoder/encoder ..."
"type" & "name" are actually tokens. The documentation should be something like
this:
Getting help:
-h -- print basic options
-h long -- print more options
-h full -- print all options (including all format and codec specific
options, very long)
-h = -- can be decoder, encoder, demuxer, muxer, filter, bsf or protocol,
and can be the specific name of the .
These are the types of things that trap those utterly stupid, lazy novices.

I mean "divide and conquer" to use all resources. If you're at 20% CPU usage, you can run 4-5 processes eg. Split video in to 4-5 segments. Process each simultaneously, each to a lossless intermediate, so you're at 100% CPU usage. Then reassemble and encode to your final format I don't think that will work very well, even if I carefully cut on key frames. The reason is that the minterpolate filter drops 10 frames and that means that at the join of each section there'll be a 1/6 second jump (or maybe worse). Note: Whether the minterpolate filter drops 10 frames or 5 frames is the subject of [FFmpeg-user] minterpolate PTS v frame count weirdness. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

[FFmpeg-user] minterpolate PTS v frame count weirdness
I've put 2 videos and a log here: https://www.dropbox.com/t/KaFx0DljtY33Qo4p = '24p-original (480 frames).mkv' https://www.dropbox.com/t/Pl7y7sYQsh5MZ1Uu = '60p-minterpolate (1195 frames).mkv' https://www.dropbox.com/t/WM81XL5Xc2ZbX6AO = '60p-minterpolate.mkv.log' The source is '24p-original (480 frames).mkv'. The target is '60p-minterpolate (1195 frames).mkv'. A 60p video should have 1200 frames. By visual comparison, the dropped frames in '60p-minterpolate (1195 frames).mkv' are NOT at the beginning. It is at this point that things get weird. The running time for both videos is indicated to be 0:20.105 (source: MPV). But '60p-minterpolate (1195 frames).mkv' never reaches its full 0:20.105 running time. Its last frame is at PTS=0:19.92, instead (source: MPV). Look... For '24p-original (480 frames).mkv': 1st PTS: 'frames.frame.0.best_effort_timestamp_time="0:00:00.00"' (source: ffprobe) last PTS: 'frames.frame.479.best_effort_timestamp_time="0:00:19.978000"' (source: ffprobe) (479 frames)/(19.978000 seconds) = 23.976374011412553809190109120032 FPS. Good! Delta-PTS = 19.978000/479 = 0.04171 s/frame. Good! For '60p-minterpolate (1195 frames).mkv': 1st PTS: 'frames.frame.0.best_effort_timestamp_time="0:00:00.00"' last PTS: 'frames.frame.1194.best_effort_timestamp_time="0:00:19.92"' (source: ffprobe) (1194 frames)/(19.92 seconds) = 59.939759036144578313253012048193 FPS. Good! Delta-PTS = 19.92/1194 = 0.01668 s/frame. Good! All good so far. The problem is that '60p-minterpolate (1195 frames).mkv's last time stamp means there are actually 10 frames missing, i.e. (20.105-19.920)/0.01668 - 1 = 10. Are there really 5 frames missing or 10 frames missing? Can anyone answer that? Or have I made a faux pas? -Mark. -- Someone's sneaking in and turning up the range so that my food burns. I'm sure of it.
