Effective Video Transcoding Project
(in cooperation with CS MSU Graphics & Media Lab)


Basic info about Effective Video Transcoding

For almost 14 years, Lomonosov MSU Graphics&Media Lab's video group has been conducting video codecs comparisons. We know that almost always there is a possibility to find efficient encoding options for every video. We did a great study and learned how to determine optimal codec settings for a large number of video classes. After comparing our encoding options for x264 to the 2015 and 2016 comparisons' options and standard ones, we received very interesting and promising results.

15% bitrate savings
in average
Encoding presets determined by our method
beats x264 developers' presets with keeping
encoding time and encoded video quality

These results are valuable for options giving the same or better objective quality of encoded video and the same or higher encoding speed comparing to standard presets. Thus, we can provide optimal encoding settings that will be a part of pareto optimal RD-curve, that is "shifted" from given encoder options.

We developed a way to find optimal encoding settings
for a large number of video classes

Percentage of file size reduction in average for a representative dataset of 77 videos:

  • We dont declare an up-to-x% bitrate reduction average file size reduction is 15% higher comparing to standard x264 presets
  • We find presets that do not reduce encoding speed and objective quality of encoded video
    You give limitations, and we guarantee the same or higher objective quality and encoding speed

You use standard presets and dont believe that it will work for your videos?

Technical info

A more detailed technical report and examples will be available soon in this section. At the moment we can share a couple of cool charts.

We created a representative dataset of 385 videos chosen from 9000+ FullHD&4K videos
