Introduction
We present a comprehensive SR benchmark to test the ability of SR models to upscale and restore videos compressed by video codecs of different standards. We evaluate the perceptual quality of the restored videos by conducting a crowd-sourced subjective comparison. For every tested codec, we show which SR methods provide the most video bitrate reduction with the least quality loss.
Everyone is welcome to participate! Run your favorite super-resolution method on our compact test video and send us the result to see how well it performs. Check the “Submit your method” section to learn the details.

Charts
In this section, you can see RD curves, which show the bitrate/quality distribution of each SR+codec pair, and bar charts, which show the BSQ-rate calculated for objective metrics and subjective scores.
Read about the participants here.
You can see the information about codecs in the methodology.
More details about metrics here.
Charts with metrics
You can choose the test sequence, the codec that was used to compress it, and the metric.
If BSQ-rate of any method equals 0, then this method should be considered much better than reference codec (codec with no SR).

Correlation of metrics with subjective assessment
We calculated objective metrics on the crops used for subjective comparison and calculated a correlation between the subjective and objective results. Below you can see the average correlation of metrics over all test cases.
* ERQA-MDTVSFA is calculated by multiplying MDTVSFA and ERQA values over the video.
Visualization
In this section, you can choose the sequence, see a cropped part of a frame from it, shifted Y-PSNR visualization, and ERQAv2.0 Visualization for this crop. For shifted Y-PSNR we find the optimal shift for Y-PSNR and apply MSU VQMT PSNR to frames with this shift. See the methodology for more information.

Leaderboards
The table below lists all methods that took part in subjective comparison SR methods for each codec and “only codec” method, which applies the video codec to the source video without downscaling or super-resolving.
You can choose the video and the codec that was used to compress it.
All sequences compressed at an approximate bitrate of 2 Mbps.
You can sort the table by any column.
