4K and 1080p on a credit SKU
One model ID covers text, a first-frame still, 1 or 3 reference images, and one optional reference clip. First Frame cannot include a reference video.
Fixed 4, 6, 8, or 10 seconds
Those four lengths only. When a reference video is uploaded, duration is not sent; billing follows the source clip instead.
720p, 1080p, or 4K
720p and 1080p share one price row. 4K costs more. Aspect ratio is 16:9 or 9:16.
Credits, not tokens
Each job deducts credits from the live table on this page. Failed tasks are not charged.
Playground and API
The fields on this page are the same parameters sent as gemini_omni_flash_ext on POST /api/openapi/submit.

What to make
A short clip from a prompt
Leave images empty. Either type returns a 4, 6, 8, or 10 second clip from text — useful for social cuts and tests.
Animate one still as the opening frame
First Frame with one image. That still becomes the first frame. No reference video in this type.
Hold a look with 1 or 3 references
Reference with one or three images. Two images are rejected.
Restyle a clip you already have
Reference with one MP4/MOV up to 10 seconds. Optionally add 1 or 3 images. Duration follows the upload.
First Frame vs Reference
Two generation types. First Frame cannot include a reference video — the playground hides that upload and the API rejects it.
First Frame
params.type = frame. 0 or 1 image. video_url is not allowed.
Reference
params.type = reference. 0, 1, or 3 images. Optional one video, max 10 seconds.
Text-to-video
Either type with an empty image list. Send video_length 4, 6, 8, or 10.
Two images
Not supported. The API returns Invalid image_url count. Allowed: [1, 3].
Ext vs official Omni Flash on this site
Compare SKUs on AIReiter only. Google's own Omni family is a different product surface and is documented on ai.google.dev.
Official SKU on this site
gemini_omni_flash_preview. Integer lengths 3–10 seconds, 720p, billed by token. Use this if you want that token contract.
This Ext SKU
gemini_omni_flash_ext. Only 4, 6, 8, or 10 seconds. 720p, 1080p, or 4K. Billed in credits from the table on this page.
When to pick Ext
You need 1080p or 4K credit rows, or you want a fixed 4/6/8/10 second SKU instead of token billing.
When to pick official
You need integer durations other than 4/6/8/10, or you are already on the token-billed 720p SKU.
How much a clip costs
Text and image jobs
Charge = the 720P/1080P or 4K row for 4, 6, 8, or 10 seconds. 720p and 1080p are the same.
Reference video, 720p or 1080p
Charge uses the reference-video row, not the duration dropdown.
Reference video, 4K
Charge is the higher of the 4K reference-video floor and a per-second 4K rate times uploaded seconds, capped at 10 seconds.
Worked examples (28 Aug 2026)
A 6-second 1080p text job billed 42 credits. The same prompt at 4K 4 seconds billed 75 credits. A 720p reference video billed 84 credits. A 6-second 4K reference clip billed 144 credits.
How to generate a clip
Same steps in the playground and the API.
Pick First Frame or Reference
Switching tabs clears uploaded images and video.
Describe the motion
Who moves, then camera and lighting. Leave images empty for text-to-video.
Set length and resolution
4, 6, 8, or 10 seconds unless you uploaded a reference video.
Submit and poll
POST /api/openapi/submit returns estimated credits. Poll POST /api/openapi/query with the same out_task_id.
Submit and poll the API
Both types share one asynchronous contract. The model ID is gemini_omni_flash_ext.
Model ID
Send gemini_omni_flash_ext. Set params.type to frame or reference. Do not send type=text.
Submit
POST /api/openapi/submit with model, params, and a unique out_task_id.
Query
POST /api/openapi/query with the same out_task_id. Completed responses include credits_used and the output video URL.
Rejected combinations
type=frame with video_url is rejected. Two images are rejected. video_length must be 4, 6, 8, or 10.

Gemini Omni Flash Ext FAQ
4K, billing vs official, two images, first-frame plus video, and API model ID.
/ 01Does Gemini Omni Flash Ext support 4K?
Yes. Resolution can be 720p, 1080p, or 4K. 720p and 1080p share one price row. 4K is a higher row.
/ 02How is billing different from official Omni Flash on this site?
Ext deducts credits from the table on this page. The official SKU on this site (gemini_omni_flash_preview) bills by token and stays at 720p. Failed Ext tasks are not charged.
/ 03Can I upload two reference images?
No. Reference accepts 1 or 3 images. Two images return Invalid image_url count. Allowed: [1, 3].
/ 04Can First Frame include a reference video?
No. type=frame cannot be combined with video_url. Upload the clip under Reference instead.
/ 05Which durations are supported?
Only 4, 6, 8, or 10 seconds. Other values are rejected. A reference video does not send duration.
/ 06Do 720p and 1080p cost the same?
Yes. They share one row. 4K is a higher row. Read the live table for the current credits.
/ 07Which API model ID should I use?
Use gemini_omni_flash_ext. Do not send gemini_omni_flash_preview for this SKU.
/ 08Is this Google's official Gemini Omni Flash?
No. This page is Gemini Omni Flash Ext, a separate SKU on AIReiter. The official SKU on this site is gemini_omni_flash_preview. Google's own Omni family is documented on ai.google.dev.
