  • FFMPEG Command to Zoom the Video is slow

    2 novembre 2015, par kishidp

    I’m trying to zoom a video using FFMPEG. I’m using this command :

    ffmpeg -i input.mp4 "zoompan=z=2" output_zoom.mp4

    It’s working fine as I get the zoom effect I wanted but the problem is that the process is slow.

    I’m seeing a warning message :

    Past duration 0.998039 too large

    and when processing the output, the fps is running around 2.8, I’m not sure if this means something.

    Anything i can do to speed this up ?

  • FFMPEG scale, zoom, and concat filter

    2 août 2018, par Karate_Dog

    I am using ffmpeg for android to produce video with mp4 format. I’m having trouble getting this command to work in FFMPEG, basically I am trying to add two images, scale them, add zoom effect, and finally concat the result into one video file. I have done something like this :

    ffmpeg 
    
-t 8 -i image1.png
    
-t 8 -i image2.png
    
-filter_complex
    
[0:v]scale=720:720[scl1]; [1:v]scale=720:720[scl2];
    
[scl1]zoompan=z=if(lte(zoom, 1.0), 1.55, max(1.001, zoom - 0.0010)):d=205, fade=t=out:st=7:d=1[v0];
    
[scl2]zoompan=z=if(lte(zoom, 1.0), 1.55, max(1.001, zoom - 0.0010)):d=205, fade=t=in:st=0:d=1,fade=t=out:st=7:d=1[v1];
    
[v0][v1]concat=n=2:v=1:a=0, format=yuv420p[v] -map [v] outputVideo.mp4

    Been tinkering with this command for a while but still can’t get it to work and I got error :

    Input link in1:v0 parameters (size 1280x720, SAR 0:1) do not match the corresponding output link in0:v0 parameters (1280x720, SAR 45:31)

  • ffmpeg : zoom over bottom (right/left) corners of an image

    22 août 2018, par Vinod Mankare

    I need to create a video with zoom effect over an image to highlight bottom right/left corner with the help of ffmpeg.

    I am trying with the following command :

    ffmpeg -loop 1 -i image.png -filter_complex "zoompan=z=’zoom+0.002’:x=’trunc(380)’:y=’trunc(287)’:d=100" -ss 0 -i audio.mp3 -c:v libx264 -crf 0 -c:a aac -strict experimental -b:v 6M -b:a 1080k -r 25 -bufsize 1080k -shortest -s 1920x1080 -aspect 16:9 -y output.mp4 2>&1

    Its working for the top (right/left) and centre element but not getting proper zoom effect for bottom corners for the same image. Please suggest what am I doing wrong, or is there any other best option to do the same ?
