Runway Ruby

Key features

Technical specifications

SDR to HDR

Standard range input only. Footage already tagged as HDR is turned away.

Up to 16-bit

16-bit float on the EXR path, 12-bit ProRes 4444, 10-bit for ProRes 422 and streaming HDR.

Up to 30s

Per pass, on sources under 4096 pixels per side. Duration is preserved.

EXR, ProRes

OpenEXR in linear light, BT.2020 PQ ProRes, and 10-bit HDR10 or HLG for streaming.

Use cases

A broadcast quality control suite at night, calibrated reference monitors glowing against a dark wall

Meeting a delivery spec

Most AI video models write a file type broadcast and streaming specs reject. This produces the master they ask for.

A compositing workstation in a darkened room, a landscape shot broken into layers across a wide display

Handing a shot to VFX

The frame sequence arrives in linear light, which is what a compositor needs to put a generated shot in a live-action scene.

A dark living room lit only by a large television, colour spilling across the floor

Streaming HDR delivery

A finished 10-bit file with the brightness data already measured, for platforms that want a deliverable, not a master.

An editing timeline glowing on a monitor in a dim suite, clips laid out in sequence

Finishing an edited clip

Edit models leave a standard range result. Running the finished cut through is how that work reaches an HDR deliverable.

A colour grading panel at night, illuminated trackballs glowing warm against a dark suite

Grading with room to move

A converted file holds far more tonal steps, so a grade holds together where it would break up on the original.

Three strips of film footage laid side by side on a lightbox, each a different stock

Mixed-source sequences

Archive files, camera exports and generated shots all land on one standard, so a sequence cut from several sources matches.

FAQs

What is Runway Ruby?
Runway Ruby is Runway's SDR to HDR video model, announced on 21 August 2026. It takes a finished standard range video and extends its brightness and colour into high dynamic range, delivering the result as OpenEXR frames, a ProRes master, or a 10-bit streaming file. It generates no new imagery and adds no resolution, though output dimensions can be cropped to a multiple of 16.
What formats does Runway Ruby output?
Four delivery paths. OpenEXR sequences carry half-float frames in linear BT.2020 light for compositing, with colour information and audio packaged alongside. ProRes arrives as a BT.2020 PQ master in 422, 422 HQ or 4444. For streaming there is 10-bit HDR10 by default, or HLG for broadcast-style delivery.
Does Runway Ruby change the picture?
Not the content of it. The conversion is a bounded, colour-preserving grade: brightness is extended into the range HDR makes available, and the frames are not re-rendered. Nothing is added to the shot, no detail is invented at the edges, and the audio passes through untouched. The one thing to check is framing, since output dimensions can be cropped to a multiple of 16.
What footage can it convert?
Any standard range video, whichever tool made it: clips generated by an AI video model, footage shot on a camera, or files from an archive. Input has to be standard range, since footage already carrying HDR information is turned away, and each pass covers up to 30 seconds on a source under 4096 pixels per side.
Where does Runway Ruby struggle?
The conversion works from what survived in the file, so heavily compressed downloads, very dark footage and blown-out highlights all give it little to work with. Clean up and upscale before converting rather than after. The output also needs an HDR-capable screen to judge, and will look flat in a browser or a standard player.
How do I use Runway Ruby on Morphic?
Ask Copilot to convert a clip to HDR with Ruby, or pick it from the model library and attach the video. There are no conversion settings to fill in, so the only choice is which file you want back. Because it sits alongside the generation, edit and upscale models, a clip can be generated, finished and converted without leaving the conversation.
