Two native recordings from 13 October 2026 are joined at the switch from JPG to PNG. A static 1280 × 853 WebP is queued with JPG selected; the format menu opens, conversion starts, and one completed JPG appears. After the cut, the same source is queued for PNG and one completed PNG appears. The app restart and reloading between runs are omitted. The build was reconstructed from the documented LocalFlux 1.0.10.0 release source. This demonstrates the controls and completion, not an output-quality review or a conversion-speed benchmark.
