Conclusion

Software output checked with a test file; no drive result

This check did not include a physical drive or firmware. It covers only file- or image-based behavior.

Existing MP4 re-inspected with ffprobe: HEVC/hvc1 and one mono AC-3 track; zero chapters and no subtitle stream. Size and SHA-256 match both the August 29 manifest and registry. No client playback, HDR or surround-audio test was performed. Different resolution and settings prevent treating the two MP4 sizes as a compression benchmark.
