During a recent Bitmovin Tech Talk, Encoding Engineer, Adithyan Ilangovan covered the recently resurrected hot topic of Super-Resolution. In his presentation, he covered how the upsampling method works, how it's developed in recent years, then showed with live examples of how it can be applied today (specifically with animated content), and how it compares to older methods of upsampling like Bicubic.

Results

21. Results - Zoomed in

22. Results - Quantified

23. Results - Quantified - Test Grade Only!
NOT A FAIR COMPARISON!

24. Anime content - 20 years old - Noisy low res.

25. Anime type of content
Use pre-Trained production grade ML model!

36. Why is it relevant to me?

37. Quality Improvements
Look beyond encoding step for quality gain.

38. Synergies
Intelligently exploit synergies with other blocks.
Example :
● Reduce bitrate and save CDN costs.
● Adapt Per-Title based on Super-Resolution.
● Many others.
