produces larg mpeg video

[kenjo]

here is a smaller verison coded in h265

video_test_60fps_h265.mp4

[kenjo]

could just do

fourcc = cv2.VideoWriter_fourcc(*'hvc1')

but runs slower and still produce a 15MB file.

ffmpeg -i video_test_60fps.mp4 -c:v libx265 -vtag hvc1 video_test_60fps_h265.mp4

is much smaller at 2MB.
