Ffmpeg input image sequence: can I add arbitrary list of images to that?

Solution 1:

glob pattern

1. Make copies of the images that you want to repeat:

   0001.png
   0002.png
   0003.png
   0003b.png
   0003c.png
   0004.png
   

2. Then use the glob pattern type for the image demuxer:

   ffmpeg -framerate 25 -pattern_type glob -i "*.png" -vf format=yuv420p -movflags +faststart output.mp4
   

I made the following assumptions:

• You're using Linux or macOS. Windows can't use the glob pattern.
• You want MP4 output.

concat demuxer

Alternative method is to use the concat demuxer which will work on all OS.

1. Make input.txt containing:

   file '0001.png'
   file '0002.png'
   file '0003.png'
   file '0003.png'
   file '0004.png'
   

2. Then use the concat demuxer:

   ffmpeg -f concat -i input.txt -vf format=yuv420p -movflags +faststart output.mp4
