Luma Ray3.2 HDR is 2x the SDR price, HDR plus EXR is 3x
Luma's API prices HDR at twice SDR and HDR plus 16-bit EXR at three times. A 5-second 1080p example, and what Sume's MP4 pipeline does and does not keep.
Luma's pricing page says HDR output is 2 times SDR pricing and HDR plus EXR output is 3 times (Luma pricing, read 2026-10-09). Ray3.2 launched on June 9, 2026 with native HDR generation and 16-bit EXR export (Luma news). Sume's docs describe no HDR or EXR option for generated video.
What does the multiplier do to a 1080p clip?
The 1x figure is the page's 5-second 1080p text-to-video price. The multipliers are applied to it here as an assumption, because the page states them as a general rule; confirm the total before a big run.
| Output | Multiplier | Cost |
|---|---|---|
| SDR | 1x | $1.20 |
| HDR | 2x | $2.40 |
| HDR + EXR | 3x | $3.60 |
What does an HDR master need downstream?
An HDR or EXR file only helps if every later step keeps it. Sume's video trim has two modes: exact re-encodes with libx264 at yuv420p, which is an 8-bit pipeline, and keyframe stream-copies the source. If you need a graded master, keep it out of the trim step and use Sume for delivery MP4s.
When is SDR enough?
For those, the 1x price is the one to budget. Reserve the 2x and 3x rows for VFX and compositing shots where the file feeds a colour pipeline.
- Social and web ads, which are watched as SDR.
- Drafts and animatics.
- Clips that will be re-encoded by a platform.
What does Sume offer instead?
Sume lists no Luma id (catalog read 2026-10-09). For 1080p MP4 with sound, gemini-omni-flash-1.1 is $0.1875 a second, so a 5-second clip is $0.9375, and 4K is $0.375 a second.
