• FFmpeg - Turn a 1280x720 video into 720x1280 video and add blur

  6 janvier 2021, par offish

  I've searched around and found multiple solutions. I've found one that works well, but the final video ends up being too big which makes the rendering slow.

  


  I'm giving it a 1280x720 video and want it to turn out like shown here with 720x1280 as the resolution.

  


  -lavfi "[0:v]scale=256/81*iw:256/81*ih,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=w=iw*81/256"


  


  This video ends up being 1280x2274 instead of 720x1280, everything else is fine except the speed and resolution.

  


  -lavfi [0:v]scale=16/9*iw:16/9*ih,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=w=720:h=1280


  


  This cuts the original video, but ends up being 720x1280, faster than the first solution.

  


  -lavfi "[0:v]scale=256/81*iw:256/81*ih,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=w=iw*81/256,scale=720:1280"


  


  This is the same as the first one, but it gets scaled again. It has the correct resolution, but is way to slow for my liking (only about 3.6 it/s, when I've tried other solutions which fluctuates around 35 it/s).

  


  I guess my scaling is wrong, but I don't understand what I should multiply and divide by, to get the result I'm looking for.

  


  Thanks.

  i will ask again i have many videos like series (dark - la casa de papel - game of thrones ) all of them without any subtitle or watermark first i burn subtitles with handbrake sec i use ffmpeg to burn watermark with videos by this code

  


  for %i in ("C :\Users\shady\Downloads\convert\01*.mp4") do ffmpeg -i "%i" -i C :\Users\fady\Downloads\convert\shady.png -filter_complex "overlay=main_w-overlay_w-10:10" -codec:a copy "C :\Users\shady\Downloads\convert\new01% ni.mp4"

  


  then i convert it to 720p with this code

  


  for %i in (C :\Users\shady\Downloads\convert\01*.mp4) do ffmpeg -i "%i" -c:a copy -s hd720 "C :\Users\shady\Downloads\convert\new01% ni.mp4"
