# -loglevel  error >>> show only errors and above level of printings

# -ss 00:03:00 -t 00:15:30 >>> cut from -ss -t time of duration (-to option for cut to -to).

# -q:v 1 -q:a 1 >>> set the qualiti of v, video and a, audio. 1 best quality, 31 worst quality.

# -filter:v "setpts=0.5*PTS" -filter:a "atempo=2.0" >>> set the speed of v, video and a, audio. \
# For video 0.5 is x2 and audio 2 is x2. (For same speed one has to be the inverse (1/X) of the other).
