How to convert a 16:9 video to 4:3 video with top & bottom blurred video bars by using ffmpeg ?
27 décembre 2018, par Wai GyiI would like to convert a landscape video to a square video with blur bars at top and bottom.
I tried to adapt the commands from the following link but not succeeded.
So, can someone share a ffmpeg command with me ?
Thank you very much for your help.
Update : I tried again and get a working command. Please check and review.
ffmpeg -i in.mp4 -lavfi "[0:v]scale=iw:iw*3/4,boxblur=luma_radius=min(h\,w)/40:luma_power=3:chroma_radius=min(cw\,ch)/40:chroma_power=1[bg];[bg][0:v]overlay=(W-w)/2:(H-h)/2,setsar=1,crop=h=iw*3/4" out.mp4

Output a video made of several video chunks of the input video
21 mai 2013, par madI was wondering if it was possible to output a video made of several extracts of the input video.
For example outputting a video made of the first 10s of each minute of the input.I know you can do it programmatically, calling
ffmpeg
several times with -ss and -t to make the chunks and then merge them, but is it possible to do it in one command using video filters ?
