  • 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 ?

    


  • 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)...

    


  • Problems using Cuda for video transcoding [closed]

    19 août 2022, par Jay Adlard

    I just bought a new pc as my faithful old windows 7 i7 laptop died. Now the laptop had both intel and nvidea gtx660m chips. When I transcoded video with handbrake the intel graphics managed 8fps when I changed over to the nvidia it managed 80fps and the graphics card got nice and hot so was obviously working.

    


    The new machine i bought is a i9 with an nvidea gtx780 running windows 10. When I tried to transcode some video hoping for it to use the cpu and Gpu but no joy,the card stays cool power usage is only a handful of watts higher than it running something simple.I had been using handbrake but I read it doesn’t support Cuda so why the laptop speeded up I don’t know. A friend of mine that is into ffmpeg came round found that ffmpeg reports no Cuda yet the card works fine in every other respect. Unlike the rest of the machine the graphics card wasn’t new but it looked like new…

    


    One thing to note I am not talking about nvenc as the quality is rather poor, no point in capturing uncompressed files cleaning them up and not using an encoder that will do 2 pass and an exhaustive search.
Can anyone recommend a reasonably priced encoder that will use the Cuda cores ?

    


    Has anyone got any idea what the problem is ?
