• Extracting segment from MTS video without re-rendering and get thin changing color band on top of output

  2 février, par David

  Extracting segment from .MTS video without re-rendering (for speed) and get a thin changing multi-color band on top of output. There is no band on the original video. How can this be prevented ?

  


  I used the following commands :

  


  set i="<input video="video" />"&#xA;set o="<output video="video">"&#xA;&#xA;%pgm% -i %i% -ss 2:40 -to 8:39 -async 1 %o% -c:v copy -c:a copy&#xA;</output>
