• ffmpeg overlay timing issue

  22 avril 2020, par Mario Iannotta

  I'm trying to add a png as overlay to a mov 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

  



    Metadata:

      handler_name    : Core Media Video
      encoder         : H.264


  



  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 :

• FFMPEG:merging Image and Audio duration getting increased [migrated]

  21 juin 2016, par Saikat Dey

  I am trying to create a video using a still image(.png) with audio(.wav) file using FFMPEG with video duration equal to audio duration but even keeping ’-shortest’ & ’-loop 1’ as flag, pegstill video duration is always 2 seconds more than audio duration.

  This is causing problem because, after the video creation i am merging several videos together to create a final video. Now what is happening is that in that 2 seconds extra time, the next video’s audio comes which is causing video-audio unsync. Even if I delay the audio stream, there is a blank sound while transition from one video to another.

  So i wanted to ask why there is extra 2 seconds and how can i remove it.
  My ffmpeg command :

  ffmpeg -loop 1 -i imgPath -i audioPath -c:v libx264 -c:a aac -strict experimental -pix_fmt yuv420p -vf resolution -b:a 192k -shortest videoPath

• Concat failing with ffmpeg 5.0 vs ffmpeg 4.1.1

  16 avril 2022, par Woolwit

  I have ffmpeg 5.0 installed on a new Silicon M1 Mac Mini running Monterey and concat is failing with the same command that has served me well on ffmpeg 4.1.1 lo, all these many years. Anyone have an idea why this command would fail on the newer version of ffmpeg.
This is with the exact same mp4 files. The ffmpeg 4.1.1. completes the concat in less than a minute.

  


  ffmpeg -i vid1.mp4 -i vid2.mp4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4



  


  Thank you !
