I'm adding an overlay image to a video, which works, but I'd like to show it only in a certain time span:

ffmpeg -i video2.mp4 -i logo.png -filter_complex \
"[0:v][1:v]overlay=10:10:enable=between(t\,0\,30)" -codec:a copy out2.mp4

This shows the error

key 'enable' not found

The syntax looks right to me. Use single quotes so you don't have to escape the expression:

ffmpeg -i input.mp4 -i watermark.png -filter_complex \
"[0:v][1:v] overlay=10:10:enable='between(t,1,2)'" output.mp4

If you don't have an enable option, make sure you use an ffmpeg version 2.0 or higher. Timeline editing is only supported there (see Changelog).

If you want multiple images overlaid, use something like this:

ffmpeg -i input.mp4 -i watermark.png -i watermark2.png -filter_complex \
"[0:v][1:v] overlay=10:10:enable='between(t,1,2)' [tmp]; [tmp][2:v] overlay=20:20:enable='between(t,2,3)'" output.mp4

  • Thanks for suggestion. Can you give me link for ffmpeg version 2.0 or higher. – Sanket990 Feb 10 '14 at 11:27
  • You can download any version from the ffmpeg homepage: ffmpeg.org/download.html — depends on how you use it on Android though. You might have to compile it from source. – slhck Feb 10 '14 at 12:55
  • thank u but getting 1 error unable to find suitable format '[tmp];[tmp][2:v] overlay=20:20:enable='between(t,2,3)'" output.mp4 – Sanket990 Feb 19 '14 at 9:39
  • Ah, sorry, the newline has to be removed or escaped. Please check my update. – slhck Feb 19 '14 at 9:46
  • i m executing update command getting error - opening an output file:overlay=10:10:enable='between(t,1,2)'. No such filter '' – Sanket990 Feb 19 '14 at 10:05
