  • Comparison Content

    The main goal of the performed comparison is getting answers on the following questions regarding lossless video codecs:
  • What codec or codecs are best for video capture and video editing applications?
  • What codec or codecs achieve the best compression ratio?
  • What advantages multithreading gives to modern codecs supporting it?
  • Only absolutely lossless codecs were examined in this comparison. Only progressive test video sequences were used.

    Main conclusions:

  • In Video Capture and Video Editing Area the overall clear winner is Lagarith.
  • In Maximum Compression area the overall winner is YULS.
  • The most balanced and flexible codec is FFV1: relatively good speed and high compression for various presets.
  • The comparison paper is 130 pages long and contains a lot of graphs to facilitate analysis like this one:
