Gemini Omni Flash edit billed per input second vs Sume reserve
Runway bills Gemini Omni Flash video-to-video at 11 credits per input second, capped at 10 seconds. Sume reserves an edit from an 8s hint, not a probe.
Gemini Omni Flash video edit: 5 reference images vs Sume
Runway's Gemini Omni Flash video-to-video edit accepts up to 5 reference images. On Sume, a video_url edit cannot be combined with any reference field.
Gemini Omni store=false sync video vs Sume's 30-second sync cap
Gemini suggests background=false, store=false, stream=false for synchronous video. Sume sync mode waits at most 30 seconds, then you poll status_url.
Gemini TTS caps 200 voices per project: picking a voice on Sume
Gemini TTS stores at most 200 voices per project for a year. On Sume you list avatars and use one whose voice.status is ready, with no stored-voice quota.
Gemini thin webhook payload vs Sume: artifact URLs in the body
Gemini webhooks send a snapshot with pointers to results. A Sume job.completed webhook already carries the media.sume.com artifact URL, so no second fetch.
Google Play screenshot rules: 320-3840 px, no alpha, 2x ratio
Play screenshots must be JPEG or 24-bit PNG, 320 to 3840 px, with the long edge at most twice the short one. Sume's 3:1 limit is looser, so check 2:1.
gpt-realtime-2.1 only supports v1/realtime: Sume TTS is a job
gpt-realtime-2.1 works only on v1/realtime, not Chat Completions or Batch. Sume TTS 1.0 is an async job you poll, which suits narration, not live talk.
Grok Imagine <IMAGE_0> tags shift with a first frame; Sume is 0-based
On xAI, pinning a first frame with image takes <IMAGE_0> and references start at <IMAGE_1>. Sume Omni tags are <IMAGE_REF_0>, 0-based by list order.
Grok Imagine video extension duration counts only the extension
In xAI video extension, duration is the added seconds only: a 10s input plus duration 5 returns 15s. Sume has no extend on Omni; chain clips from a last frame.
Grok Imagine video input: base64 or file_id vs Sume HTTPS URLs
xAI's extension page accepts a source video as a public URL, base64 data URI or file_id. Sume's video fields take public HTTPS media URLs only.
Grok Voice Transcribe 2.0 price per hour vs Sume STT per minute
xAI lists STT at $0.10 per hour batch and Voice Transcribe 2.0 since Sep 17. Sume STT bills per audio minute, reserving 1 minute by default, max 10 minutes.
Hedra Character 3 price per second vs Sume Avatar Video 720p
Hedra Character 3 lists 2.5, 5 and 6.25 cents per second at 540p, 720p and 1080p. Sume Avatar Video is 720p with standard, plus and max quality tiers.
Hedra Character 3 aspect ratios vs Sume Avatar Video ratios
Hedra Character 3 lists seven aspect ratios including 9:21 and 21:9. Sume Avatar Video supports five: 1:1, 3:4, 9:16, 4:3 and 16:9, default 9:16.
HeyGen videos:write and videos:read vs Sume scopes mcp:read/write
HeyGen needs videos:write to create and videos:read to poll. Hosted Sume OAuth has mcp:read and mcp:write, no paid scope; spend is wallet admission.
HeyGen Assets folders (flat) vs Sume media inputs by HTTPS URL
HeyGen Assets library folders are app-created, flat, and usable as folder_id destinations. Sume takes media as public HTTPS URLs, with no folder step.
HeyGen do_not_translate_terms vs Sume: handle terms before speech
HeyGen brand glossaries now take do_not_translate_terms and forced_translations for video translation. Sume has no glossary field; handle terms in your text.
Ideogram 8K output resolution API vs Sume 512 to 4K tiers
Ideogram 4.0 takes output_resolution 1k, 2k, 4k or 8k as a pixel budget. Sume's image route takes a normalized 512, 1K, 2K or 4K tier.
Ideogram API 402 Payment Required, and Sume image billing
Ideogram tool endpoints can return 402 for insufficient credits or quota. Sume image billing is all-or-nothing: failed generations are not billed.
Ideogram ad localizer API: exact_copy vs a Sume edit prompt
Ideogram's ad-localizer takes one language per call and an exact_copy mapping. On Sume you send the ad as a reference and spell out the copy in the prompt.
Ideogram ad resizer API safe zones vs Sume aspect_ratio 4:5
Ideogram's ad resizer returns an exact WIDTHxHEIGHT inside a platform safe zone. Sume's image route picks an aspect_ratio and resolution tier instead.
Ideogram ad variations API: one axis per call vs Sume n
Ideogram's ad-variations tool varies people, setting, group_size or scene. Sume has no axis field: describe the change in the prompt and set n up to 10.
Ideogram async generation_id polling vs Sume's 202 job envelope
Ideogram returns images directly unless async or webhook_url is set, then you poll /v2/generations. Sume blocks up to 30s, then returns a 202 job.
Ideogram dry_run price quote vs Sume image pricing lines
Ideogram's dry_run=true returns a PriceQuote without generating. Sume's images API has no dry_run; read endpoint pricing lines from the catalog first.
Ideogram ghost mannequin API views vs Sume input references
Ideogram's ghost-mannequin tool takes front, back, left, right, top and bottom photos and a required view. Sume takes a flat input_references list.
Ideogram API image URLs expire: download, or use Sume URLs
Ideogram's quickstart says image URLs expire, so download what you keep. Sume returns Sume-hosted signed URLs in data[].url. Where each result lives.
Ideogram layerize API: text blocks vs Sume's flat image
Ideogram layerize returns positioned text blocks plus a text-free base. Sume's images API returns flat Sume-hosted signed URLs, with no layer output.
Ideogram magic_prompt off and JSON prompts vs Sume passthrough
Ideogram 4.0 magic_prompt auto, on or off controls prompt rewriting. Sume has no passthrough parameters in v1, so that switch is rejected.
Ideogram material swap API: 4 masks vs Sume's one mask_url
Ideogram's material-swap tool takes up to 4 masks and material images. Sume's images API has one optional mask_url plus up to 16 references.
Ideogram model pose variants API vs a Sume edit prompt
Ideogram's pose tool takes an `instruction` field. Sume has no pose endpoint: you edit with a prompt, references and n up to 10 per call.
Ideogram API seed for repeatable results vs Sume's 400
Ideogram endpoints take an optional seed for repeatable results. Sume's image schema has seed, but no model advertises it, so it returns 400.
Ideogram Z-Image resolution rules vs Sume image_size
Ideogram Z-Image takes WIDTHxHEIGHT, sides in multiples of 16, area up to 1,048,576 px. Sume uses 512/1K/2K/4K tiers and GPT Image 2.5 custom pixels.
Edits 15-minute export vs Sume's 900-second trim and detach cap
Edits now exports up to 15 minutes on iOS. Sume trim and audio detach also top out at 900 seconds of output, from a source up to 1800 seconds.
Edits bilingual captions vs Sume: language is only a STT hint

Instagram Edits compares up to 3 reels by views and watch time. Sume video inspect adds what the clips contain: probe facts, stills and an optional transcript.

Edits lyrics captions vs Sume video captions with script_text
Edits generates lyrics from a selected track and styles them as captions. With Sume you supply the lyric text as script_text and choose a caption style.
Edits Restyle with a prompt vs Sume video router edit mode
Edits Restyle changes a clip's look from a text prompt. In Sume, send video_url to the video router with a prompt to use gemini-omni-flash-1.1 edit mode.
Edits audio vibe filter vs a Sume music prompt (no duration field)
Edits lets you filter audio by vibe like chill or bossy. Sume music takes a text prompt instead, with no duration, seed or temperature parameter to pin.

iPhone 18 Pro screenshot size: 1206x2622 and 1179x2556
iPhone 18 Pro screenshots (6.3-inch) are 1179x2556 or 1206x2622. Neither fits Sume's multiple-of-16 image rule or its 2160 Timeline edge cap.

iPhone Duo screenshots: 1398 x 2034 or 2034 x 1398 outer, 2007 x 2853 or 2853 x 2007 inner. Sume Timeline can hit the outer sizes, not the inner ones.
Cloudflare 524 on a Sume jobs_wait: transport, not job outcome
A 524, 522, 523 or 525 on jobs_wait is a transport failure, not a job result. Re-issue jobs_wait on the same ids or read jobs_status once. Never resubmit.
Kling 4.0 10-bit HDR at 1080p and 4K: what later edits keep
Kling says 4.0 outputs 10-bit HDR at 1080p and 4K. Sume's exact video_trim re-encodes to yuv420p; keyframe trims stream-copy. Verify before you grade.
Kling 4.0 Creative Recreation vs Sume reference ingest manifest
Kling 4.0 Creative Recreation borrows a reference video's pacing and shot structure. Sume reference ingest returns the shots, text and audio facts first.
Kling 4.0 five reference videos vs Sume's 1 to 3 video URLs
Kling 4.0 takes up to 5 reference videos, 30 seconds combined. Sume lists 1-3 reference_video_urls on the legacy shape and varies per model.
