Video Generation creates video clips from text prompts and optional references. Use it when you want generated footage or reference-guided video changes from the canvas.

​
How It Works

Describe the shot, subject, style, camera motion, and desired duration. Mosaic sends the prompt and selected compatible references to the generation model, then returns a video asset that can feed downstream tiles. Use Video Generation for:
  • Product shots and cinematic b-roll
  • Social clips from a creative prompt
  • Reference-guided motion from uploaded images or clips
  • Sound-enabled generated scenes
MiniMax H3 generates 2K clips of 5 to 15 seconds with native audio. Without selected context it runs text-to-video; with any selected image, video, or audio it runs reference-to-video, which accepts up to 9 images, 3 videos, and 3 audio clips (12 files total). Seedance 2 supports selected image, video, and audio references. Seedance 2.5 generates up to 30 seconds at 480p, 720p, or 1080p and accepts up to 30 images, 10 videos, and 10 audio clips (50 files total); with no references it runs text-to-video, with one image it runs image-to-video, and with anything else it runs reference-to-video. Gemini Omni Flash supports prompt-only generation, selected image references, or one selected video reference. For Gemini Omni Flash, use either selected images or one selected video, not both. Selected video input uses the first 10 seconds and does not include audio.

Example

For 4K output, use:
4K Seedance generations are billed at 2x normal Seedance.For Gemini Omni Flash with image references, use selected images and set duration/aspect ratio:
For MiniMax H3 text-to-video, set the duration in seconds and an aspect ratio. Output is always 2K with native audio.
For MiniMax H3 reference-to-video, select subject images, video clips, and audio clips to keep consistent across the generation. Any selected context routes to this mode.
MiniMax H3 is billed at 13 credits per output second, plus 13 credits per reference-video second and 4 credits for each reference image beyond the first five.For Seedance 2.5, set the resolution and a duration up to 30 seconds. Selected references route the request automatically: no references runs text-to-video, exactly one image runs image-to-video (which always uses the source aspect ratio), and anything else runs reference-to-video. Each reference video or audio clip must be at least 1.8 seconds; selected video references are trimmed to 30 seconds combined, and audio references are trimmed the same way.
Seedance 2.5 is billed at 23.11 credits per 720p second and 10.28 credits per 480p second, discounted to 60% of those rates when a video reference is selected. With video references, reference-video seconds are billed alongside output seconds; image and audio references are not billed. An "auto" duration is charged for the 30-second maximum up front and adjusted down to the delivered video’s length once the generation finishes.For Gemini Omni Flash with video reference, select one upstream video. The selected video input uses the first 10 seconds; duration and aspect ratio come from that video.
