DemiMedia by ALLUSIONS

Let the picture lead.

DemiMedia is a Windows film player built so the picture leads. You choose the result you want; it plans how to get there on your hardware, and it keeps the details one step away.

Quiet playback in DemiMedia: a generated colour-bar test clip fills the frame with an English SDH subtitle line, and no controls or panels are on screen.
Quiet playback: the controls hide after a moment and only the picture and subtitles remain. A generated test clip, captured 23 Sep 2026 during the DemiMedia interface work that became build 90e0a87.

It starts quiet, too.

One question before anything else: what do you want to watch? A file, a folder or a stream. Everything else waits one step away.

The DemiMedia start screen: Open a film. The rest can wait., with Open file, Open folder and Open URL buttons and a drop area that says It plays from this PC.
The start screen, captured 23 Sep 2026 from build 90e0a87, merged to main as 96da0de on 24 Sep.

Choose the result, not the settings.

Pick what you want from the picture: preserve the original look, improve detail, make motion smoother, clean up compression and banding, or a balanced improvement. Smart Fill can also reframe eligible video using source pixels only. Then say how strong, and whether to favour efficiency or quality.

There are four starting points: Automatic, Reference, Enhanced and Compatibility. The implementation parameters stay one level deeper.

DemiMedia's picture choices: Automatic selected, a list of outcomes with Balanced improvement chosen, Strength set to Normal, Performance set to Balanced, and below it The plan explaining each decision in a sentence.
Outcome choices and the plan they produce, each decision explained in a sentence.

See the plan before you press Play.

Before anything plays, DemiMedia reads the file and shows what it found and what it intends to do: the scaling it chose, whether motion is left alone, what audio path it will use, and why.

Nothing is marked as observed until the player has actually reported it.

A generated test clip, Harbour Lights, ready to play: Play button, Enhanced choices, and the Playback details panel listing the source picture, codec, dynamic range and colour, then the plan with one sentence of reasoning per decision.

While it plays, the detail stays one step away.

Healthy playback is quiet: no badges, no logs, no controls you did not ask for. Open Playback details and each question gets its own answer.

Requested
What you asked for.
Planned
What DemiMedia decided to do on this file, display and hardware.
Observed
What the player actually reported, shown only once it has reported it.
Health
Whether playback is keeping up, and what changed if it is not.

What it does, and what it does not claim

Plays through

mpv, libplacebo and FFmpeg; automatic MPC-BE fallback is unavailable in the current build

Hardware decoding on paths where it is supported

Decoded PCM as the safe audio default; HDMI bitstream optional

Offers, never silently

NVIDIA RTX Video Super Resolution and RTX Video HDR, where the hardware and active display path support them

Source-only Smart Fill for eligible video, with observed fallback to original framing when analysis is not trustworthy

Qualified native Dolby Vision Profile 7 processing and Profile 7 to Profile 8.1 conversion for compatibility, with delivery claims kept separate from requests

Does not claim

Universal Dolby Vision or HDR support on every display

Proprietary Dolby Vision display signalling unless the active path actually proves it

AI frame generation or generated scenery; smoother motion currently blends real frames and Smart Fill only reframes source pixels

That a requested enhancement was delivered before the player reports it
