FFMPEG: Add black frames at start and end of video

[Andrew Baldinger]

What is that 60 after the -t doing?

[Andrew Baldinger] “What is that 60 after the -t doing?”

That’s the total output duration. So the output will be 60 seconds in that example. I had to add -t to manually declare an output duration because -shortest isn’t working. This is only needed for the example with audio. The -t value should be input duration + stop_duration.

[Andrew Baldinger] “ffmpeg -i input -filter_complex "[0:v]tpad=stop_duration=10:color=black[v]" -map "[v]" output

Right?”

That will work assuming you only want video and no audio.
