For almost 14 years, Lomonosov MSU Graphics &Media Lab's video group has been conducting video codecs comparisons
We developed a way to find optimal presets for a large number of video classes
Everything is fair! We don't declare an "up-to-x%" bitrate reduction — saverage file size reduction is 15% higher comparing to standard x264 presets
Percentage of file size reduction in average for a representative dataset of 77 videos
You provide us an uncompressed video and we provide you an improved compression relative to your or standard presets
Send us uncompressed video and your encoding preset to know how much you will save with our presets
Receive a report with optimal presets for your video and their gain under your preset
Choose preset that satisfy your conditions on encoding speed
Use this preset for encoding of similar videos
Assuming 15% bitrate reduction in average you can:
$26 when 1000 people watched 1-hour-video
$11 a month to store 1000 hours of video
$4 for encoding of 1-hour-video
The following example of x264 encoding results for an "apple_tree" video sequence shows that standard presets that works fine for a large number of different videos are not the best for a particular one.
Our approach is validated on representative set of 385 videos chosen from 9000+ FullHD&4K videos
We can find best presets for any limitations on encoding speed or bitrate without reducing objective quality (not a "JND" approach)
We can validate the result using subjective evaluation by large number of observers
