ffmpeg -i input.mp4 -i logo.png -filter_complex overlay=Ww:Hh output.mp4 8.3 Remove the video logo ffmpeg -i input.mp4 -i logo.png -filter_complex overlay=0:Hh The ffmpeg -i input.mp4 -i logo.png -filter_complex overlay=Ww output.mp4 To Post it elsewhere? Look at the following: ffmpeg -i input.mp4 -i iQIYI_logo.png -filter_complex overlay output.mp4 The Want to post to a video, I can use the following command:

ps: If 540 is not written, write it as -1, that is scale=960:-1, that is also possible, ffmpeg will notify the zoom filter to maintain the original aspect ratio when outputting. I want to make the file smaller without destroying the resolution.įfmpeg -i input.mp4 -vf scale=960:540 output.mp4 b:v mainly controls the average bit rate.įor example, the bit rate of a video source is too high, 10Mbps, and the file is too large. There are three options for ffmpg to control the bit rate, -minrate -b:v -maxrate The bit rate of general audio is only fixed There are several types, such as 128Kbps, Because online video needs to consider the bandwidth it can provide.Įxample, a file is 20.8M, and the duration is 1 minute, then the bit rate is:īiterate = 20.8M bit/60s = 20.8 1024 1024*8 bit/60s = 2831Kbps The above is to start from 15 seconds and cut it out for 5 seconds.īit rate control is more important for online video. ss indicates the time to start cutting, -t indicates how much to cut.
