What Flashhead is for
Flashhead animates a still into a short video clip. Upload the starting frame, describe the motion, and the studio returns a clip in about 90 seconds (Credits).
Flashhead is cheap enough that a generation usually fits the free Knowlify plan's credits. A typical run is about 90 seconds.
Pick Flashhead for image to video at Credits and ~90s. Compare it with Ai Avatar, Argil Avatar on the related cards below if you need a different look, speed, or input type.

On Knowlify (knowlify.com/generate/flashhead). You do not need a separate playground. Flashhead runs in the studio next to document-to-video.
Can I make a longer video with Flashhead?
Flashhead itself produces a short clip. On Knowlify you can take that output, or skip it and upload a document, and generate a full narrated video with a script you can edit.
What do I need to run Flashhead?
A prompt and a source still. Flashhead will not invent the starting frame for you on this mode.
