FFMpeg Benchmark – Effect of Threads and Bitrate on Image Quality


If you have been following along, we have recently been doing a series on command line video tools. Here I review a recent ffmpeg benchmark I performed. After reviewing the documentation and encoding a few sample videos, my questions were as follows:

  • How long does each of the various ffmpeg preset take for h264 encoding?
  • How much faster is the encoding with multiple threads?
  • For a given variable bitrate, does a given preset make a difference in image quality?
  • What is the optimal preset for ffmpeg?
