• Cut multiple parts from a video and merge them together

  24 janvier 2018, par DragonBorn

  I am trying to cut specific parts out from a video and then merge all those parts into a single video file using nodejs and ffmpeg.

  Here’s my code and currently I can cut only one part out of the video from .setStartTime to .setDuration and that part is being saved.

  var ffmpeg = require('fluent-ffmpeg');
  
  
  
  var command = ffmpeg()
  
    .input('./videos/placeholder-video.mp4')
  
    .setStartTime('00:00:03')
  
    .setDuration('02')
  
    .output('./videos/test.mp4')
  
  
  
    .on('start', function(commandLine) {
  
      console.log('Started: ' + commandLine);
  
    })
  
  
  
    .on('end', function(err) {   
  
      if(!err)
  
      {
  
        console.log('conversion Done');
  
      }                 
  
    })
  
  
  
    .on('error', function(err){
  
      console.log('error: ', +err);
  
    }).run();

  How do I cut out multiple parts out from the video and merge them in a single video file. I know about .mergeToFile method but how do I use it after cutting different parts from my video.

  I tried using .setStartTime and .setDuration twice like below but the first one’s are being ignored.

  .input('./videos/placeholder-video.mp4')
  
  .setStartTime('00:00:03')
  
  .setDuration('02')
  
  .setStartTime('00:00:15')
  
  .setDuration('05')
  
  .output('./videos/test.mp4')

  Tune rate-distortion modeling to account for frame light change

  When the variance is far less than sse, the block is considered to
  be under light change. All the energy is compacted into DC coeff
  and can be coded at low cost. In such situation, switch the rate-
  distortion modeling from sse+var based back to variance based.

  Note that this is a temporary solution to handle the rare situations
  where the scene light changes.
