• FFmpeg overlay PNG after scaling has not necessary black borders

  24 mars 2021, par Mikołaj Henklewski

  I have two PNG files that I want to add to the video :

  


  

  • Two lines text

  


  • Circle

  


  


  but on the final video, they have black borders (they do not have it originally !) Actual Result.. The question is why FFmpeg is adding it on scale effect, and how to avoid adding it ? Command is :

  


  ffmpeg -i 3d9678e2e58c4d08a24363468d0cfd3e.mp4 -i caption-1616544596077-d.png -i caption-1616544596080-d.png -filter_complex

• Green overlay with multiply blend mode using FFMPEG

  25 mars 2014, par Barto

  I'm currently working on a project which needs video editing.
  Here for I'm using ffmpeg, which is working pretty well, except for 1 filter.
  Every video should get an overlay with the Photoshop multiply blend mode.
  I'm using the ffmpeg blend mode, but unfortunately the video gets a green overlay as you can see in the screenshots.

  Original Image
  

  Edited with ffmpeg

  What I'm trying to achieve
  

  Does this has something to do with the mode I'm working in ?
  Below is my current code
  

  #!/bin/bash
  
  vagrant ssh -c "./ffmpeg \
  
  -i /vagrant/public/uploads/video/bw_RzWecVH02p.avi -i /vagrant/public/img/red_ellipse.png \
  
  -filter_complex "blend=all_mode='multiply'" \
  
  /vagrant/public/uploads/video/overlay_RzWecVH02p.mp4"

  Here is my ffmpeg output

• ffmpeg blured bars on vertical movie - Error while opening encoder

  14 mars 2021, par hexedecimal

  I'm trying to use ffmpeg to prepare a mp4 file which is vertical recorded for upload to youtube.
(on a synology DS220+)
In the output file I want to have no black bars on the side but blured sodebars of the movie itself.
This I'm trying to do whit this code (in the end I want to automate this process, but maybe there is a better way to do this) :

  


  ffmpeg -i input.mp4 -lavfi "[0:v]scale=1920*2:1080*2,boxblur=luma_radius=min(h\,w)/20:luma_power=1:chroma_radius=min(cw\,ch)/20:chroma_power=1[bg];[0:v]scale=-1:1080[ov];[bg][ov]overlay=(W-w)/2:(H-h)/2,crop=w=1920:h=1080" output.mp4 


  


  unfortunaly i get a error message :

  


  Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height


  


  In mine search on the internet I have tried multiple ways to get this done but whit all the same error result.
This was making me think that the ffmpeg install is faulty or I was trying wrong code.

  


  Could somebody help me whit this "project"
