Gemini Omni AI Video Generator (Gemini Omni Flash, 1080p)
Google's flagship video model, and the only one here that generates sound with the picture.
Gemini Omni is Google's current video generation model, the successor to Veo, which was shut down in October 2026. It is the top tier on this platform and the only model here that produces native audio: ambient sound, effects and speech generated as part of the same clip rather than added afterwards.
Quality is the other reason to pick it. Motion is coherent, subjects hold their shape through movement, and physical interactions such as liquid pouring or fabric settling behave plausibly. It also handles editing, keyframe interpolation and extension, which is more than the model it replaced could do.
It is the most expensive option here by a wide margin, so the practical pattern is to block out an idea on a cheap model first and spend Omni credits once you know the shot works. The Fast tier runs the same model at 720p for roughly a third of the cost.
What Gemini Omni is best at
Clips that need sound as well as picture
The highest motion quality available here
Plausible physics and material behaviour
Final renders of a shot you have already blocked out
Native audio Generates ambience, effects and speech with the picture, so a clip can stand alone without a sound pass.
Motion coherence Subjects keep their shape and proportions through movement instead of melting at the edges.
Plausible physics Pouring, falling, splashing and cloth behave close enough to real that the clip does not read as AI at a glance.
1080p output The highest resolution tier here, which matters when the clip is going on a site hero or a large screen.
Where Gemini Omni falls short
By far the most expensive model here per second of video.
Only 16:9 and 9:16. Square output is not available, and a 1:1 request is served as 9:16.
Duration is a prompt instruction rather than a hard parameter, so clip length is approximate.
Generation takes minutes, not seconds. Leave the tab open.

Prompts that work on Gemini Omni
Write the sound in
A kettle boiling on a gas stove in a quiet kitchen. Steam rising. Sound: water rolling to a boil, a soft click as it switches off, faint room tone.
Omni is the only model here that generates audio, and it only generates the audio you describe. A sound line is free quality.
One camera move, one action
Slow dolly push in on a barista pulling an espresso shot. The only movement is the camera and the stream of coffee.
Coherence holds when there is one motion to track. Two simultaneous moves is where any video model starts to warp.
Block cheap, finish here
Same prompt you tested on Minimax or Omni Fast, rerun at 1080p once the framing and motion are right.
At this price, Omni is a finishing model. Use the cheap tiers to find the shot and this one to render it.
What Gemini Omni costs
Cost on Prompt Reverse, 4 second clip: 100 AI Credits, 8 second clip: 200 AI Credits. AI Credits come from a one-time credit pack and never expire, with no subscription and no separate provider account.
Gemini Omni vs the other models
Gemini Omni Fast: The same model at 720p for roughly a third of the credits. Start here.
Kling video: Switch for the best results when a real person's face is in the frame.
Gemini Omni is Google's video generation model, specifically gemini-omni-1.1-flash. It replaced Veo, which Google shut down in October 2026, and it generates native audio alongside the video.
Does Gemini Omni generate sound?
Yes, and it is the only model here that does. It produces ambience, effects and speech as part of the same clip, but only the sound you describe in the prompt.
What is the difference between Omni and Omni Fast?
They are the same model at different resolutions. Omni renders 1080p, Omni Fast renders 720p for roughly a third of the credits. Use Fast to find the shot and Omni to render it.
Can Gemini Omni make square video?
No. It renders 16:9 and 9:16 only, and a square request is served as 9:16. Kling, Minimax, Luma and Grok all support 1:1.
How long does generation take?
Minutes rather than seconds. The page keeps the request open while it renders, so leave the tab in the foreground.
