News on Pi5, GScrop and timelapse.py

With Pi5 bigger frames can be captured at same framerate compared to Pi4B, without frameskips.

mplayer plays 320x96@536fps video (of analog clock center) captured with GScrop tool.

pi@raspberrypi5:~ $ GScrop 
Format: [narrow=1] [cam1=1] /usr/local/bin/GScrop width height framerate ms [us]
pi@raspberrypi5:~ $

That tool uses rpicam-apps/blob/main/utils/timestamp.py for frame delay and skip analysis:
