Gemini Omni Flash Edit

Endpoint

POST https://api.roasos.com/v1/video-edit/gemini-omni-flash

Send your API key as a bearer token. The key needs the scope api:write. Every paid request also needs an Idempotency-Key header.

The envelope fields quote_only, quote_id, webhook_url and wait_timeout_seconds behave the same on each model endpoint. Refer to Jobs and Quotes and credits.

Good at

Style, setting and other prompt-directed visual changes that do not require replacement identity images. Ask to preserve motion, cuts, framing and existing text, then review the result; matching frames or output length is not guaranteed. Use /v1/video-edit/kling-4 when you need replacement identity references. Use /v1/video/gemini-omni-flash for new footage.

Pricing

The reservation unit is one source_second. Pricing key: gemini-omni-flash.

Reserved credits use measured source duration and the catalog rate. Completion refunds credits proportionally for shorter output and caps longer output at the approved quote. The source is not charged again as an input-video offset. Send quote_only: true for the exact reservation.

Modes

• edit

Provider endpoints: google/gemini-omni-flash/v1.2/edit.

Request fields

The schema is strict. A field that is not in this table gets 400 unsupported_option. The field names are the roasOS role names. One role has one name in every family.

Media

This endpoint accepts these media roles:

• video_url — the source video

Every other role is refused: avatar_id, elements, product_id, product_images, references, reference_images, image_url, end_image_url, scene_id, scene_image, video_urls, audio_urls, audio_url, voice_id. A refused role gets 400 unsupported_option.

Prompt

• Limit: 10,000 characters.
• Name the requested change and state which details should remain.
• Preserve existing captions and graphics unless their removal is requested. Do not append a new-generation no-text suffix.
• Voice editing is unsupported, and there is no explicit keep-original-audio control. Do not promise original voice or soundtrack preservation.

Not exposed

These catalog entries describe omitted inputs, pinned values and source constraints. They do not imply that the provider accepts every listed field.

• aspect_ratio — not accepted by this public endpoint.
• resolution — pinned to 720p; the edit tier is left at its provider default.
• duration_seconds — not accepted by this public endpoint.
• generate_audio — not accepted by this public endpoint.
• references — not accepted by this public endpoint.
• image_url — not accepted by this public endpoint.
• end_image_url — not accepted by this public endpoint.
• voice_editing — not accepted by this public endpoint.
• regional_availability — pinned to not available in the EEA, Switzerland or the UK.

Example

The three steps are always the same: quote, run, poll.

# 1. Quote. Nothing is spent.
curl -X POST https://api.roasos.com/v1/video-edit/gemini-omni-flash \
  -H "Authorization: Bearer roasos_sk_live_..." \
  -H "Idempotency-Key: 0f1c9e2a-gemini-omni-flash-0001" \
  -H "Content-Type: application/json" \
  -d '{"quote_only":true,"prompt":"A woman holds the bottle at eye level in a bright kitchen, morning light, static camera.","video_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/video_url.mp4"}'
# 200 { "data": { "kind": "quote", "quote_id": "q_7Hk...", "credits": 3, "expires_at": "...",
#        "confirmation": { "model": "gemini-omni-flash", "example": "3s_source" } } }

# 2. Run. Same body, same Idempotency-Key, quote_id in place of quote_only.
curl -X POST https://api.roasos.com/v1/video-edit/gemini-omni-flash \
  -H "Authorization: Bearer roasos_sk_live_..." \

# 201 { "data": { "id": "gen_...", "status": "queued", "credits_reserved": 3 } }

# 3. Poll, then read the result.

Today

Use POST /v1/video-edit/gemini-omni-flash with prompt, video_url and shared quote controls, or the corresponding MCP tool. Browser Edit and agent generateVideo.sourceVideo reach this operation through the same quoted public endpoint. Explicit Edit intent with replacement assets is refused; it cannot silently become reference generation. Legacy generic requests retain their existing source-shape routing.

• One workspace-owned MP4 source, at most 15 seconds and at most 100 MiB. No first frame, last frame, replacement images, avatar/product assets or identity elements.
• The public edit contract exposes no duration, aspect ratio or resolution control. Resolution is pinned to the provider-default 720p; additional provider tiers are not exposed.
• fal does not serve uploaded-video editing to users in the European Economic Area, Switzerland or the United Kingdom.
• The quote reserves credits from measured source duration at the 720p rate. Completion refunds credits proportionally for shorter output and caps longer output at the approved quote. The source is not charged again as an input-video offset.
