### Change framerate ### Change framerate
Changing framerate is quiet common, as the world does not have a consistent standard. Facebook Live wants 30fps, YouTube wants 30 or 60fps. There's a nice summary on the [https://documentation.apple.com/en/finalcutpro/usermanual/index.html#chapter=D%26section=4%26tasks=true](Apple FCP site).
Change framerate:
``` ```
gst-launch-1.0 -v filesrc location="$SRC" ! decodebin ! videoconvert ! videorate ! video/x-raw,framerate=5/1 ! autovideosink gst-launch-1.0 -v filesrc location="$SRC" ! decodebin ! videoconvert ! videorate ! video/x-raw,framerate=5/1 ! autovideosink
``` ```
