Omni Flash Video
Overview
Use this skill to turn a video idea plus reference media into a practical Gemini
Omni Flash / Google Flow generation plan. Prefer short, atomic clips and clear
reference roles over one overloaded prompt.
Default Workflow
- Identify the generation mode:
- Frames to Video for a still image that should animate.
- Ingredients/References to Video when preserving a character, object,
style, voice, or environment across clips.
- Video to Video editing when editing an uploaded/generated clip.
- Storyboard / multi-shot when a sequence needs several generated clips.
- Assign each input a role before prompting:
- start frame
- end frame
- character/identity reference
- style reference
- destination/environment reference
- prior-shot continuity reference
- Write one prompt per clip. Keep each clip to one main action, one camera
behavior, and one transition intent.
- Generate one or more canaries in Flow. Review for first-frame match,
action readability, last-frame usability, and continuity.
- If a clip is close, iterate conversationally in Flow with specific edits.
If the composition is wrong, revise the prompt/reference setup and regenerate.
- Save prompts, reference paths, generated outputs, and review notes in the
project folder.
Read References
- Read
references/official-research.md when you need current access paths,
supported Flow features, durations, limits, or source links.
- Read
references/prompt-playbook.md before writing prompts, especially for
image-to-video, start/end frames, or door/portal transitions.
- Read
references/paper-portal.md when working on the sketch-to-door project.
Prompt Rules
- Prompt motion from the reference rather than re-describing every visible
detail in the image.
- Use positive instructions:
static camera, locked-off shot, clean pencil sketch animation, one continuous shot.
- Keep style changes at transition points. Doorways/portals are useful reset
points for model consistency.
- Use short clip durations for controllability. Treat 4-10 seconds as a clip
unit, not a whole story.
- Avoid asking for several story beats in one generation. Split them.
- Use negative notes sparingly and as nouns/qualities:
extra limbs, extra characters, colored background, clutter, text.
Output Checklist
For each generated clip, record:
- Flow mode and model
- source frame/reference files
- prompt text
- duration and aspect ratio
- output file or URL
- what worked
- what failed
- whether the last frame is usable as the next seed
