Gemini Omni 1.2 Flash: New 15-Second Clips and Lower Pricing

Across 15 seconds, the camera never cuts. After passing through the hoop, the marble strikes the first domino and starts a chain reaction that ends at the bell.

Marble continuity is the clear error. An additional rounded red shape appears behind the first domino, though the frames do not establish whether it is a separate object. Later, the tracked marble leaves the frame and reappears behind the fallen row without visibly traveling there.

Sound timing is mixed: The first domino click matches the visible contact, but the bell rings about 0.15 seconds late. Because the action finishes early, the final few seconds are almost still.

I also think the way the marble crossed the hoop wasn’t fully believable.

Editing one object without changing the scene

Next, I changed one attribute and asked for everything else to stay.

Change the red glass marble to a deep sapphire blue. Keep its size, transparency, reflections, and movement the same.

Preserve the wooden track, brass hoop, dominoes, bell, lighting, camera movement, and original sound effects. The chain reaction should happen at exactly the same moments as in the original video.Powered by

Color is the only intended change: the marble turns deep blue but keeps the same size, transparency, position, and highlights. Everything else, including the scene and event timing, remains unchanged.

It kept the mistakes too: the ambiguous rounded shape and the marble's later reappearance are now blue at the same moments. You have to notice these things because unmentioned flaws carry into the next edit.

The edit generated a new audio track. Those effects return in the same pattern, but about 45 milliseconds later, roughly one video frame. That delay becomes more noticeable across later edits.

Motion through a full style change

For the final edit, I asked for handmade stop-motion while keeping the blue marble and timing.

Re-render the entire marble-run scene as a handcrafted stop-motion animation made from painted paper, cardboard, and textured fabric.

The wooden track becomes layered cardboard, the brass objects become painted miniature props, and the blue glass marble keeps its recognizable color and shape.

Preserve the original sequence and timing: the marble rolls down the track, passes through the hoop, strikes the dominoes, and the bell rings at the end. Keep the original camera movement and sound effects, with the tactile imperfections of handmade stop-motion animation.Powered by

Blue color and glass texture survived, while the track and dominoes became layered cardboard. Camera path and event timing stayed unchanged.

Only part of the restyle landed. The bell looks painted, but the hoop and workshop background remain realistic, and no fabric appears. A frame-by-frame comparison shows steady movement between frames, with no stepped stop-motion rhythm.

The comic lines around the bell were unrequested but leave the sequence intact. Compared with the original, the soundtrack shifted by about 85 milliseconds, placing the bell roughly 0.23 seconds after impact.

Test results, generation time, and cost

Generation finished in under a minute, while each edit took around two minutes. The three completed videos totaled about $3.55, calculated from returned usage at Google's published rates.

Edits cost slightly more because Google processes the source video again.

Gemini Omni 1.2 Flash Pricing and Availability

Gemini Omni 1.2 Flash costs about $0.07 per second at 720p, and the API has no free tier. Google apps use their own plans and quotas. I used 720p for the test; higher resolutions cost more.

Gemini Omni 1.2 Flash pricing by resolution

At that public rate, a 15-second clip costs roughly $1 before the cost of processing its source material. The 1080p and 4K options cost more because the model enlarges a lower-resolution video:

Google also charges for processing a source video during an edit. Google app subscriptions use separate pricing.

Where can you access Gemini Omni 1.2 Flash?

Developers can use Gemini Omni 1.2 Flash through the paid Gemini API, Google AI Studio, or Google Cloud.

Google also offers the model through several apps. Each product uses its own plan and quota:

• Flow, for directing scenes and making follow-up edits
• Google Vids, which gives up to three 15-second videos per month at no cost to anyone with a Google account or Workspace subscription, per the Vids announcement
• The Gemini app, with 15-second videos rolling out to Google AI Ultra subscribers
• Google Ads, for video campaigns

Gemini for business is where Google's posts disagree: the launch post calls it generally available there, and the Cloud post says "coming soon." Uploaded video editing is unavailable in the European Economic Area (EEA), Switzerland, and the UK, while videos generated by the model remain editable there.

Gemini Omni 1.2 Flash Limitations and Early Reviews

Google names sports with rapid movement, quick script changes, and complex physics as remaining limits. The Gemini API guide adds that negative instructions belong in the main prompt and only English has full support. The domino sequence falls under complex physics, but one marble run cannot test every claim in the announcement.

Most early reviews come from companies that sell access to the model. A Segmind test published on launch day reports that explainers and simple edits followed its prompts, while chart points were placed at the wrong heights and some instructions were skipped.

My test contains no dialogue, speech matched to mouth movement, text shown in the video, or numbers, so it says nothing about those areas. I also used detailed edit prompts, while Google's prompt guide recommends simple instructions.

Final Thoughts: Is Gemini Omni 1.2 Flash Worth Using?

Gemini Omni 1.2 Flash answered the central question in pieces. The sequence and color change held, while the marble jump and late bell carried into later versions. The style request changed materials, but the motion still looked like the original.

There’s room for improvement: The model fits draft clips and simple variations that someone will review. Long edit chains make less sense when continuity or exact timing carries the idea, because old mistakes survive and cost rises with each turn. The blue marble survived; so did the flaw beside it.
