CONTENT-AWARE VIDEO-CODEC TUNING
Reduce video streaming & storage costs by 20% on average
after changing 1 line of encoding settings
What do we do?
We analyse video codecs and find best encoding settings for given videos. Our settings increase encoding efficiency: faster encoding, lower bitrate for the same quality, or better quality for the same bitrate.
Video-codec tuning is a process of codec optimisation for particular tasks, such as compression of specific videos (movies, TV series, CCTV, interviews, CGI etc.) or working at given speed limits by variating encoding settings.
We offer a solution to the problem of optimal video codec configuration in the form of software for automatic selection of effective parameters and in the form of service, the result of which will be one or more of the most effective configurations of video codec parameters for your video sets.
Our clients are owners of video on demand (VOD) and streaming services, online cinemas, holders of large video archives, video codec developers, etc.
The challenge of video-codec tuning
Standard encoding presets are usually tuned by the developers to work efficiently on average for a variety of encoding cases. Adjusting your codec for content it works with allows to utilize unused reserves of video codec and boost its performance.
Is it simple to find good encoding settings?
Let's consider an example: tune x264 for one 20-second-long video
- x264 has ~50 encoding settings
- Different combinations of settings influence encoding performance in an unpredictable way
- Exhaustive search for optimal settings will last 22,000,000,000,000 centuries (~488,000 Earth ages!)
Our algorithms can tune any video codec for your videos
in just a few days
Example of reducing costs for streaming, storage and increase compression efficiency by an average of 15%
Codec tuning allows to decrease video size and encoding bandwith:
- up to 40% less bitrate with the same encoding time and video quality
- up to 10 times faster with the same bitrate and encoded video quality
For example, our settings for x264 encoder optimized for a set of 77 different videos produces 15% less bitrate than standard presets and 8% less than developers' presets which were tuned by the developers specifically for MSU Video Codec Comparison 2018
Advantages of our approach
Works with all video encoding use cases
All kinds of videos: CCTV, Ads, Movies, Self-driving, Aero, etc. Any use cases: online streaming, universal or ultra-high-quality encoding. Validated on 20000+ real videos
Any video-codec or cloud encoding service
Our technology is codec-independent, it works with the codec mathematical model and requires access only to the encoding options, the meaning of which may be hidden
Preserves or improves the video quality
With our technology video file size decreases without quality loss. Our optimization algorithms work with any target quality, bitrate and encoding speed

Our stack of technologies
Our stack of technologies and programming languages: Python, C++, NumPy, XGBoost, scikit-learn, CatBoost, OpenCV, FFmpeg, Docker, etc. We build, develop and keep up-to-date models linking video codec parameters, source video characteristics and compressed video characteristics through machine learning such as “learning with a teacher” and “reinforcement learning” using various machine learning methods.
Developed models are the basis of the software we offer for the automatic selection of effective encoding settings. The software recognizes the features of the video stream and selects the best codec configuration based on the encoder model. Our models also allow us to quickly find effective configurations of video codec parameters within the framework of consulting services. At the request of customers, we develop or customize software related to video encoding, decoding, video quality assessment, video processing to improve its quality
