    Enforce effective motion vector search range

    This commit explicitly enforces the effective motion vector range
    in the motion search stage. The range needs to be the intersection
    of UMV border, effective absolute motion vector value range, and
    the target search area.

  • How to zoom out video to a single point with ffmpeg ?

    17 mars 2023, par Peter.k

    I have an video and try to zoom out the entire content from 1.0 to 0.1, or literally, to a single point. I don't know the zoom value of it, so first I try to use 0.1 variant. It should decrease image 10x and fill with black background entire area outside the image.

    


    I try with code :

    


    ffmpeg -i e:/gals/1/logo_3s.mp4 -vf "scale=2560:2560,setsar=1:1,zoompan=z='if(lte(zoom,0.1),1.0,max(1.001,zoom-0.01))':d=1:x='(iw-(iw/zoom))/2':y='(ih-(ih/zoom))/2'" -s "1280x1280" -b:v 3000k -r 60 -t 3 e:/gals/1/loop_z.mp4


    


    but nothing happens - only video is stretched but keeps right dimensions. it also looses some frames or without -t 3 extends from 3 to 7 seconds.

    


    What I'm doing wrong ? Maybe I could re-scale each frame by some ratio and make it progressively smaller ?

    


  • Invalid radius value in BlurMask Ffmpeg

    15 avril 2022, par Vivek Thummar

    I'm using boxblur filter to blur specific area of video using cropping library, when i fire command sometimes it works well but sometimes it's showing me error.
Command and error are as below :

    


    ffmpeg -ss 00:00 -t 02:43 -i input.mp4 
-filter_complex crop=28:24:20:14,boxblur=25[fg];[0:v][fg]overlay=20:14,
-vcodec libx264 output.mp4


    


    This is throwing error - Invalid luma_param radius value 25, must be >= 0 and <= 12

    


    In this command crop=... can be vary according to user need and boxblur=25 is static.
So, if the error is related to boxblur then the question is why sometimes it works or if this was not the problem then what is the problem and solution ?
