  image on image overlay is working by enable given time but when video overlay into image is not working correctly

  


• Multiply blend mode using FFMPEG adds green overlay

  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
  

  $ overlay_edit.sh

• Converting from FLV to MP4 using ffmpeg

  14 juillet 2016, par Brad

  I have a library of several thousand flv files which I need to convert to mp4. I’m trying to use ffmpeg to do so but I’m running into some issues.

  Primarily :

  1) I can’t switch from FLV to MP4 without re-encoding. If I do I get a message from ffmpeg saying "Could not find tag for codec flv1 in stream #0, codec not currently supported in container"

  2) If I re-encode the videos, the resultant videos are lower quality (I see artifacting in VLC) AND larger. For example one video went from 2.5MB to 4.3MB (almost double in size)

  Given number two you may be asking yourself - why convert then ?

  The answer is I need to stream these to mobile devices (phones/tablets etc) and flv isn’t supported. So I need to convert the files but I can’t tolerate more than a minimum change in quality, and preferably zero to no increase in size.

  Here’s the ffmpeg command I’m running :

  ffmpeg -i $_.FullName -movflags faststart -profile:v baseline -level 3.0 "$($_.BaseName).mp4"

  (Note that I’m running ffmpeg from powershell so :

  $_.FullName = the original file name 
  
  "$($_.BaseName).mp4" = the original file name with mp4 extension)

  Can any FFMPEG guru’s help me to understand what I’m doing wrong ? Is there some set of parameters I can use to make this conversion result in less loss of quality and similar size ?

  Note I’ve also tried "-c:v libx264 -preset veryslow -crf 23 -c:a copy". Using present "veryslow" doesn’t result in any appreciable difference.

  UPDATE
  I’m using the following options :

  ffmpeg -i $_.FullName -c:v libx264 -preset veryslow -crf 19 -c:a copy "$($_.BaseName).mp4"

  Here’s the full output :
