Mediaivo creator test pack — 2026-09-19

Generated four-second synthetic fixtures, executed Mediaivo commandFor()/runFfmpeg(), checked streams with ffprobe, decoded audio to mono 48 kHz float samples to measure sample peak and RMS. Not true-peak or LUFS measurements.

Synthetic chart/tone tests are not a benchmark for faces, speech, music, HDR, variable-frame-rate phone footage or every codec. No audio or video autoplays. Encoding versions may change byte counts.

You may use, copy, modify and redistribute the generated chart and tone fixtures and their outputs for any purpose. No attribution required. This permission does not apply to third-party software.

Run the corresponding tools at https://mediaivo.com/media-lab. See manifest.json for options, measurements and SHA-256 hashes. The source WAV is a synthetic 440 Hz reference tone, not a speech recording. Begin playback at low device volume. The static chart and moving chart are controlled tests, not real-world filming claims.
