• Ubuntu ffmpeg watermark position

  24 juin 2022, par Arnas Pečelis

  so I have command :

  



  ffmpeg -i prepared/video.mp4 -i units/video_watermark.png -filter_complex overlay=main_w-overlay_w-10:main_h-overlay_h-10 -codec:a copy moved/video_test.mp4


  



  which should describe watermark position on bottom right but the watermark appears on the bottom center. what i'm doing wrong ?

  



  also I tried this command :

  



  ffmpeg -i prepared/video.mp4 -vf "movie=units/video_watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" moved/output.mp4


  



  but with it watermark was not added, video was corrupted becouse of response :

  



  


  [aac @ 0x3556540] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.

  


  



  where is the clue ?

  


• FFMPEG Zoom pan to a particular coordinate x and y in a video

  23 novembre 2024, par crysis

  I'm trying to zoom-in in a video at a particular coordinatates x, y when video reaches at timestamp in duration. I'm using this command for the zoompan filter

  


  x = 784
y = 550
timestamp = 2
width = 1920
height = 1044

zoompan_filter = (
    f"zoompan=z='if(between(in_time,{timestamp},{timestamp + 0.5}),"
    f"1+2*(in_time-{timestamp}),"
    f"if(between(in_time,{timestamp + 0.5},{timestamp + 1}),"
    f"2-2*(in_time-{timestamp + 0.5}),1))':"
    f"x='{x}-(iw/zoom/2)':y='{y}-(ih/zoom/2)':"
    f"d=1:s={width}x{height}"
)


  


  x and y are the coordinates where I want to zoom in. This filter works fine for most of coordinates but the zoom is weird near center of the screen. It zooms in a straight line then suddenly pans to right a little when zoom about to end.

  


  

  


  How do I make the zoom straight ? Any help would be greatly appreciated.
