How to Make Your First AI Video with Gemini Omni Flash
No filming experience or technical background needed. This walkthrough takes you from opening the generator to downloading your first clip, one small step at a time — about ten minutes end to end.
Before you start: two quick things
- A working account is all you need. New users get 150 free credits (valid 30 days) after verifying their email. Your first 4-second clip costs 45 credits, so the free tier goes a long way.
- If you plan to use image-to-video, prepare one clear photo: subject filling most of the frame, even lighting, uncluttered background. The photo sets the floor for the final video.
Seven steps to your first video
Decide what this first video shows
Keep it small. Pick one still subject with one simple action: "a cup of coffee with rising steam on a wooden table" or "an orange cat stretching on a windowsill". The simpler the action, the higher your first-run success rate. Say the subject, the action, and the setting to yourself — that is all your prompt will be.
Choose text-to-video or image-to-video
The generator offers both. No source material, or a purely imagined scene? Use text-to-video. Making a video of a product, a shop, or a pet and already have a photo? Use image-to-video: upload the photo, then describe how it should move in the frame. A reference photo keeps the subject far more stable, and it is the route most beginners should take.
Write your first prompt
Four things, no more: what the subject is, what it does, where the scene is, and what the light is like. Example: "a white ceramic mug on an oak table, steam rising slowly, soft morning window light from the left, background blurred". Chinese or English both work. If you would rather start from something proven, copy a recipe from our prompt template library and swap in your own subject.
Pick 4 seconds for the first run
Gemini Omni Flash generates 4, 6, 8, and 10-second clips. Start at 4 seconds — it costs the fewest credits and returns fastest, which makes it the cheapest way to test whether your prompt works. Once the prompt holds up, rerun it at 6 or 8 seconds for the real shot. Same logic for quality: draft tier to iterate, HD for the final take.
Hit generate and wait about a minute
Results usually land within a minute depending on length and quality. No need to watch the progress bar — spend the time deciding what to change next. If a generation fails, the credits are refunded automatically and you can retry with one click from History, prompt intact.
Check the result against a short list
Ten seconds, four checks: Is the subject shape intact? Did it perform the one action you asked for? Did anything odd wander into the background? Is there text in the frame that should not be there? Fix the first three by editing the prompt. The last one you can ignore — precise text belongs in post-production subtitles.
Download it, or change exactly one thing and rerun
If the clip works, download it. If not, change one part of the prompt only. Slow the action down, or fix the light — never both at once. When you change three things per run, you never learn which one helped. Two or three single-variable rounds are usually enough to get a usable shot.
Time to the generator and try it. A rough first run is completely normal — the checklist in step six tells you exactly what to fix.
Four questions beginners ask most
Can I write prompts in English?
Yes. Gemini Omni Flash understands both English and Chinese prompts, and both work well. That said, if your subject is a Chinese dish, brand, or place, describing it in Chinese is often the more precise option.
Can I use the videos commercially?
Yes. Videos generated through Omni can be used for commercial purposes, including product pages, ads, and social media content.
What happens to my credits if a generation fails?
Failed generations are refunded automatically. You can retry with one click from your History page without rewriting the prompt.
Should my first video be a 10-second HD clip?
No. A 10-second clip costs 90 credits — double a 4-second one — and the whole point of the first run is to validate the prompt, not the polish. Prove the scene at 4 seconds first, then produce the final version at a longer duration in HD.
Make your first video on free credits
Sign up, verify your email, and your credits are ready. A first 4-second clip costs just 45. No credit card required.
