ECHO  -o  Output file. Default is the same as input file, sans extension
ECHO  -r  Resize output width in pixels. Default is original input size
ECHO  -f  Framerate in frames per seconds (default 15)
ECHO  -s  Start time of the animation (HH:MM:SS.MS)
ECHO  -e  End time of the animation (HH:MM:SS.MS)
ECHO  -x  Crop the input video (out_w:out_h:x:y)
ECHO  -y  Preview animation using FFplay (part of FFmpeg)
ECHO      Useful for testing cropping, but will not use exact start/end time
ECHO  -p  Opens the resulting animation in the default image viewer
ECHO  -v  Set FFmpeg log level (default: error)
