Evaluation of video compression rate control performance on the HEVC Class B dataset, measured using ∆R and BD-Rate metrics.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Rate Control |
| Dataset (including any stated split) | HEVC Class B |
| Metric | Delta R |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Delta R](<https://www.sota2.com/research/sota/rate-control-on-hevc-class-b.md?metric=Delta%20R>): Lower is better; unit: SCALAR.

- [BD-Rate](<https://www.sota2.com/research/sota/rate-control-on-hevc-class-b.md?metric=BD-Rate>): Lower is better; unit: PERCENT.
