Helpful FFmpeg & FFprobe commands

index.sh

// Use ffprobe to get stream value
$(ffprobe -v error -select_streams v:0 -show_entries stream=r_frame_rate -of default=noprint_wrappers=1:nokey=1 becky.mp4)

Note: If the source video was in H.264 format you can also use the H.265 command to produce a final video in H.265/HEVC format. Since H.265 is 25–50% more efficient you should be able to reduce the Bitrate and still maintain the same video quality.
