Luma Ray 3.2 HDR price: 2x SDR, and 3x with EXR, worked out

On Luma's API pricing page (read 2026-10-02), HDR output is priced at twice the SDR price and HDR plus EXR output at three times. For a 5-second Ray 3.2 clip at 1080p, listed at $1.20 in SDR, that makes $2.40 for HDR and $3.60 for HDR plus EXR. Sume's video outputs are standard video files, not HDR or EXR.

The multiplier, applied

The SDR prices are read from the page; the HDR and EXR columns are the stated multipliers applied to them.

When HDR is worth paying for

HDR and EXR output are for colour grading pipelines: you want more dynamic range to grade in post, or frames for a compositor. If the clip is going straight to a social feed as a standard video, the doubled price buys range you will not use.

A reasonable pattern is to draft in SDR at a lower resolution and only regenerate the keepers in HDR, since each clip is billed per generation.

What Sume outputs

Sume's video catalog, as described in the video docs, lists resolutions, aspect ratios, durations and audio per model; it has no HDR or EXR output field. Jobs return a standard video file you download from the content URL. Sume does not offer an HDR or EXR multiplier, and does not list a Luma Ray model in the docs read for this page.

If you need a graded HDR deliverable today, generate it at the vendor that offers it and keep Sume for the rest of the pipeline, such as drafts, reframes and assembly.

Budget check

The multiplier is read from one price page and may change, so verify before a large order.

• Count only the clips that will actually be graded.
• Keep SDR drafts at 540p or 720p; the page prices them far below 1080p.
• Confirm the multiplier still applies to your resolution and clip length on the live page.
