title: Use Lagarith for encoding
body: <p>I have a loss less mp4 file (YUV 4:4:4) encoded using x264 with me. I want to convert it to loss less avi using Lagarith. Earlier, to compress using lagarith, I used virtualDub. But that option now goes out since virtualDub does not support mp4 files as input. Any suggestions on possible softwares that support lagarith output and take a loss less mp4 as input ?</p>
  
  <p>This exercise to convert to loss less avi is part of an experiment on video codecs, so, an alternative measure won't be useful. </p>
  
  <p>Thanks.</p>
