Professional and HDR output formats

Runway’s flagship models — Gen-4.5 and Aleph 2.0 — can deliver video in professional formats beyond standard H.264 .mp4: ProRes and PNG image sequences for editorial workflows, 10-bit SDR masters for grading, and true HDR on Gen-4.5. Set outputFormat on the request to choose a delivery. These formats carry a per-second surcharge — see pricing.

Editorial containers

Available on Gen-4.5 and Aleph 2.0:

`outputFormat`	Delivery
`mp4` (default)	H.264 `.mp4`
`prores`	ProRes `.mov`
`png_sequence`	`.zip` of PNG frames (plus a separate `.wav` when the output has audio)

For prores, optionally set proresProfile (422 Proxy, 422 LT, 422, 422 HQ, 4444, or 4444 XQ; default 4444).

10-bit SDR

`outputFormat`	Delivery	Models
`sdr_rec709_10bit`	HEVC Main 10, Rec.709 `.mp4`	Gen-4.5, Aleph 2.0

HDR and high bit-depth (Gen-4.5 only)

Gen-4.5 HDR outputs are true HDR renders — graded into BT.2020 with measured HDR10 metadata. Aleph 2.0 does not deliver native HDR. For HDR content with Aleph 2.0 you can chain an edit through SDR to HDR.

`outputFormat`	Delivery
`hdr10`	HEVC Main 10, BT.2020 + PQ `.mp4`
`hlg`	HEVC Main 10, BT.2020 + HLG `.mp4`
`hdr_pq_12bit_master`	12-bit 4:4:4 BT.2020 + PQ `.mov` (lossless)
`hdr_prores`	BT.2020 + PQ ProRes `.mov`
`hdr_png_sequence`	`.zip` of 16-bit PNG frames + colorimetry sidecar (plus a separate `.wav` when the output has audio)
`hdr_exr_sequence`	`.zip` of half-float OpenEXR frames as linear BT.2020 light (1.0 = 100 nits) + colorimetry sidecar (plus a separate `.wav` when the output has audio)
`hdr_exr_acescg_sequence_1_3`	The EXR delivery as scene-referred ACEScg for ACES 1.3 pipelines — reads with the stock `ACES - ACEScg` input transform
`hdr_exr_acescg_sequence_2_0`	The same scene-referred ACEScg delivery for ACES 2.0 pipelines (inverted through the ACES 2.0 Output Transform)

For hdr_prores, proresProfile accepts 422, 422 HQ, or 4444 (default 422 HQ).

The ACEScg EXRs are scene-referred: the delivered picture is inverted through the ACES 1.3 Output Transform (Rec.2100 PQ, 1000-nit), so reading the frames with the stock ACES - ACEScg input transform and viewing through your ACES pipeline reproduces the delivered picture — no Read-node changes needed. The colorimetry.json sidecar names the ACES version and the inverted transform.

SDR to HDR

Always set model to ruby on POST /v1/video_to_hdr. Converts SDR video into true HDR, keeping the source pixels and audio. Delivers 10-bit HEVC in HDR10 (outputFormat: "hdr10", the default) or HLG ("hlg"), a BT.2020 + PQ ProRes .mov editorial mezzanine ("hdr_prores", with proresProfile of 422, 422 HQ, or 4444; default 422 HQ), or a .zip of half-float OpenEXR frames for compositing, as linear BT.2020 light ("hdr_exr_sequence") or as scene-referred ACEScg for ACES pipelines ("hdr_exr_acescg_sequence_1_3"; reads with the stock ACES - ACEScg input transform; both zips include colorimetry and provenance sidecars, plus audio.wav when the source has audio). Inputs must be SDR, at most 30 seconds, and under 4096 pixels per side; output dimensions may be cropped to a multiple of 16. See pricing for the 20 / 40 credit per-second rates by source resolution.
