Resources you can inspect and cite
- Camera-footage comparison: the same 964,911-byte source becomes 243,705 bytes with Balanced or 122,658 bytes with Smaller file. Dimensions and nominal duration are retained; picture quality is not lossless.
- Human-speech gain comparison: hear a prepared quiet excerpt at 125% and 200%, with measured sample peak and RMS.
- Marked rotation chart: inspect what a physical 90° rotation changes.
- Resize versus crop: compare padding with removed edges.
- SRT and WebVTT comparison: two downloadable cues with exact timings and accented text.
- Inspect the reference file: compare the flower sample’s codec, dimensions and duration with its manifest.
These are examples, not broad performance benchmarks. The manifests identify inputs, settings, output hashes and encoder versions.
