HI,
thanks for your replies.
@Tony: Not sure what the viewing of the video has to do with the generation?
@MrDave: Here is the (hopefully) relevant part of the configuration:
minimum_frame_time 0
movie_max_time 0
movie_output on
movie_bps 400000
movie_quality 60
movie_codec mp4
timelapse_codec mpg
movie_duplicate_frames off
movie_extpipe_use off
framerate 25
width 1920
height 1080
As far as understood, it is encoded.
Best Regards
Stefan
