  • h265 and CRF in a specific region

    11 juin 2021, par D.Giunchi

    I need to create an h265 with a region that is compressed with a different CRF.

    


    I was thinking of generating 2 compressed videos from the original using h265 with different CRFs and then blending each frame. The final step is to create an h265 video from the blended frames using the min CRF between the two. Does it make sense or there is a simpler and better way ?

    


  • How to capture region screen with Watermark using FFmpeg on Mac ? [duplicate]

    25 janvier 2021, par Yong Ju

    I was tried to capture region screen using FFmpeg on Mac.
So, I ran some command line for it.

    


    ffmpeg -f avfoundation -i "0" -vf "crop=500:500:400:800" -pix_fmt yuv420p -y -r 25 out.mov


    


    Now, I want to capture region screen with watermark.
I don't know how to configure command line for it.
If you have good experience in this field, Please advice me.

    


  • ffmpeg - overlay a video with rounded corners

    4 novembre 2019, par asi

    I am successfully using overlaying a scaled (smaller) video on top of a larger one but am struggling to understand how could I give the small video a rounded corners mask.

    Edit

    thanks to @loogan comment I’ve managed to get a working command that created applies a circular mask :

    ffmpeg 
    
    -i main.mp4 
    
    -i vignette.mp4 
    
    -filter_complex 
    
      [1:v]scale=300:-1[scaled];
    
      [scaled]split [scaled0][scaled11]; 
    
      [scaled0]trim=end_frame=1,geq='st(3,pow(X-(W/2),2)+pow(Y-(H/2),2));if(lte(ld(3),780*780),255,0)':3:3,loop=-1:1,setpts=N/FRAME_RATE/TB[mask];
    
    [scaled1][mask]alphamerge[cutout];
    
    [0][cutout]overlay=x=W-w:y=0[v];
    
    -map [v] 
    
    -map [a]  
    
    output.mp4

    but how to get from a circle to a rounded rect still eludes me. cant quite get what are the params that geq expects and the math to generate them.

    assuming that the video that needs masking is 200 * 300 and the corners should have a 5px radius, is there a geq command that can create this mask ? maybe en ellipse ?

    or maybe a better way would be to use a pre-made png as a mask ?

    any insights welcome
