Freeze frame
Watch as an animation →Stop the picture to emphasize a character's introduction, a decisive moment or a punchline.
A "this is me"-style self-introduction, a decisive expression, an ending.
Cut the clip at a clean frame with no distortion, then extend that last frame by 1 second with tpad=stop_mode=clone:stop_duration=1. tpad only clones the clip's last frame, so to freeze a moment in the middle of a scene you have to cut first. Overlay text as an image made with Pillow.
Cut the clip at its decisive clean frame, then hold that frame for one second to land the punchline: ffmpeg -t 2 -i in.mp4 -vf tpad=stop_mode=clone:stop_duration=1 -an out.mp4. Pick a frame without distortion, and put a title card or caption over the freeze.
