✦ Background

What is Gemini Omni?

Gemini Omni is a multimodal AI video model that accepts text, images, a reference video, reusable characters, and reusable voices in a single generation call. Up to 7 reference slots can be used per video, where each image takes 1 slot, each video takes 2, and each character takes 1.

Where most video models force you to pick text-to-video OR image-to-video, Gemini Omni handles all of them simultaneously: caption the camera move, drop in product reference photos, attach a video for motion guidance, and bind a recurring character and a cloned voice — all in one POST.

Tryonr exposes Gemini Omni through three studios — Generate Video, My Characters, and My Voices. Characters and voices are reusable: build them once, drop them into every video. Output runs up to 4K with optional 9:16 vertical for short-form.

✦ Why Gemini Omni

Why creators choose Gemini Omni

Six reasons to build your video workflow on Tryonr's Gemini Omni studio.

True multimodal in one call

Text prompt, reference images, 1 reference video, up to 3 reusable characters, and 1 cloned voice are submitted together. No chained pipelines, no inter-step quality loss.

Reusable character library

Define a character once from a photo + description, get back a reusable character_id, then drop it into any future video. Identity stays consistent across shots.

Custom voice cloning

Clone a voice from a Kie preset, give it a name, optionally seed it with example dialogue, and reuse the resulting voice_id across all your characters and videos.

Up to 4K cinematic resolution

Generate at 720p, 1080p, or 4K. Pick 4, 6, 8, or 10 second clips. Aspect ratio 16:9 for cinematic or 9:16 for TikTok, Reels, and YouTube Shorts.

Video-to-video motion guidance

Upload a reference video with explicit start/end timestamps to drive motion exactly the way you want. Gemini Omni reads the cadence and applies it to your scene.

Transparent credit pricing

Every generation shows its credit cost upfront before you submit. Failed generations are refunded automatically — idempotent, no support ticket required.
