How to convert a video to different resolution's using ffmpeg
20 septembre 2018, par Binoy CherianThere are some commands i currently use to convert videos but I’m not sure about the quality of the videos converted.
For low resolution :
ffmpeg -i input.mp4 -vcodec libx264 -crf 20 output.mp4
And for high/same resolution (low->high is not feasible, but is there something we can do ?)
ffmpeg -i input.webm -qscale 0 output.mp4
I read that qscale preserves the video quality.Since I’m new to ffmpeg. I would like to have some tips. Please let me know if you need any information. Any help would be greatly appreciated.
