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 :

Seeing this answer i tried using-



[0:v]setsar=1[v0]; [0:a0] [1:v]setsar=1[v1]; [1:a1]




but did not worked !



How can i resolve this ?
