  • Make blurred background faster with ffmpeg

    26 septembre 2022, par Peter Czask

    I have a vertical videos which I'll like to make them horizontal 1920x1080 with blurred background.

    


    I do it with this command :

    


    ffmpeg -i input.mp4 -vf 'split[original][copy];[copy]scale=ih*16/9:-1,crop=h=iw*9/16,gblur=sigma=20[blurred];[blurred][original]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2'  output.mp4 


    


    which that code I'm satisfied with the result, except that it takes very very long time to produce it. Is there any way to speed it up ? I noticed that the blurred part on the background uses half of the overlay video (non blurred), I'll like to blurry just with the edge (or 10 pixels) of the non blurred video (if this makes the encoding faster)...

    


  • How to add watermark with delay in FFmpeg

    28 décembre 2022, par Мохамед Русланович

    Am trying to put a gif file in all the edges of the video. So am using this command

    


    ffmpeg  -y -i film.mp4 -stream_loop -1 -i gif.gif -filter_complex \ 
"[1]colorchannelmixer=aa=0.8,scale=iw*1:-1[a];[0][a]overlay=
x='if(lt(mod(t\,16)\,8)\,W-w-W*10/200\,W*10/100)':
y='if(lt(mod(t+4\,16)\,8)\,H-h-H*5/200\,H*5/200)':
shortest=1" 
 -acodec copy output_task_3.mp4


    


    But now am required to put the gif file on each edge with delay of 10 minutes

    


    For exmaple :

    


    1- render gif at top left for only 16 seconds.
Then wait 10 minutes

    


    2- render gif at top right for 16 seconds.
Wait 10 minutes

    


    3- rendder gif at right buttom for 16 seconds.
Wait 10 minutes

    


    4- render gif at left buttom for 16 secnods.
Wait 10 minutes

    


    This scenario should be repete till the movie ends.

    


    How can i archive this ?

    


  • Can't reproduce a mp4 video in any of my browsers (Ubuntu 22.04.4)

    8 mai 2024, par user3303019

    This one is weird. I can't reproduce the following video in the browser (tried brave, chrome, firefox and edge).

    


    https://a-pop.stg.intuitivo.ai/assets/animations/wowMomentOpenDoor.mp4

    


      


    1. I have installed all sorts of codecs I may need and the regular video player plays the file no problem.

      


      2. 


    2. For some reason it was working on Brave up until last week and it wasn't on chrome.

      


      3. 


    3. It only happens on Linux apparently. Windows, Mac, android and iOS have no problem with the browser playing the animation.

      


      4. 


    


    I don't have a clue what could be happening. I've checked other mp4 videos online and they work (from v.reddit)
