This answer shows how i can glue the pictures into one.
Is it possible to take a certain amount of frames (for example 10) and put them together in one picture? With a single command.
Your mentioning frames so i assume you mean frames from the same movie and you would like to use ffmpeg and lets also assume output would be jpeg:
ffmpeg -i <some-movie> -frames 1 -vf "select=not(mod(n\,200)),tile=10x1" image.jpg
explanation:
frames 1 from the manual: Stop writing to the stream after 1 frames.select=not(mod(n\,200)) select every 200th frame.tile=10x1 Make a filmstrip 10 images wide and 1 image height.Change the selection and tile values to your needs.
