ffmpeg overlay timing issue
22 avril 2020, par Mario IannottaI'm trying to add a
png
as overlay to amov
video with ffmpeg (version 4.2.2) using the following command :


ffmpeg -i ./input.mov -i ./overlay.png -y -filter_complex "overlay=enable='between(t,1,4)'" ./output.mp4



Now my understanding of
overlay=enable='between(t,1,4)
is that the overlay will be added at one second and will be removed at 4 seconds since the begin of the video but the output is somehow different.


The overlay is added at roughly 2:66 and it is removed at 5:14.



Trying with different values result in even more confusing outputs.



eg :



- 

-
between(t,3,10)
—> 3:12 | 11:05 -
between(t,2,7)
—> 2:65 | 7:22 -
between(t,1,2)
—> the overlay is not added ad all









The metadata of the input video are the following

I also tried to convert the video to mp4 (with
ffmpeg -i input.mov -vcodec copy -acodec copy out.mp4
) before applying the overlay but the issue is still there.


Edit : I downloaded a test mp4 video and the command is working as expected so it is definitely something wrong with my input video. Any idea what it is ?



Edit 2 : Here's the output of ffmpeg command :

Why console reports a lot of frame drops on my conversion ?
24 juin 2020, par SososlikI'm trying to convert a mp4 video file to another H265 mp4 video file. During conversion I'm applying crop, trim and a drawbox.

The result file looks good to the eye. But the question is why I see a lot of dropped frames on the console during conversion process ? (last line on the log, parameter "drop=").

I searched google, but it says that normal if you do framerate conversion, but I'm not doing that and don't want any framerate change, just apply my filters and convert to H265. What I'm doing wrong ?
