FFMPEG Examples and Notes

Notes:

• To Watch your Video Immediately Use: ffplay
• To Save your Video to a File: ffmpeg -i INPUT.mp4 OUTPUT.mp4
• To Get Video Info: ffprobe INPUT.mp4
• Is -vf the same as filter_complex ?

Params:

• -ss 13:21SKIP TO
• -t 2:11DURATION
• -loglevel panicDON"T SHOW ANY PRINTOUTS

Ideas on How to use these:

• Trivia: Ask Questions, then count down Timer, then reveal
• Guess the Movie: Show Video Blurred, while giving Hints
• HELP me think of others.

#1- Crop Video Between Times:

ffmpeg -y -ss 00:10:14.6 -to 00:10:39.1 -i "Family Guy S19E10.mkv" -vf scale=1920:1080,setsar=1:1 ~temp1.mp4 ffmpeg1.mp4
