On-Off Dolby Vision demo — the contrast test
The On-Off Dolby Vision demo is the largest file in the entire Dolby Vision library at 678MB and 2 minutes 16 seconds. The premise is straightforward: dark scenes cut directly to bright ones with minimal transition. That specific scenario is where static HDR metadata fails most visibly and where Dolby Vision’s dynamic tone mapping does the most work. If the transition from a dark interior to a bright exterior looks clipped or crushed on your display, the Dolby Vision processor isn’t handling the luminance shift correctly.
At 678MB in TS format it’s also the only non-MP4 file on this page and the only TS file in the Dolby Vision section — the container is less common and some players handle it less cleanly. Worth testing playback before committing to the full download.
Palette — On-Off Dolby Vision demo companion file
44 seconds at 257MB. The name describes the content — a wide range of saturated colors designed to push the gamut pipeline across the full spectrum in a short runtime. Useful as a quick wide gamut check before running longer files.
People
76 seconds at 308MB. Skin tone rendering under Dolby Vision tone mapping — faces and human subjects are the most demanding test for color accuracy because the eye detects shifts immediately. Any oversaturation or hue shift in skin tones shows up clearly here in a way that landscape content won’t reveal.
Sails
44 seconds at 229MB. Outdoor content with high contrast between bright sail fabric and dark water — similar dynamic range challenge to On-Off but in a natural setting rather than artificial cuts. The shorter runtime makes it a useful companion to On-Off for a quick contrast evaluation.
