Start Frame
¿Qué es Start Frame?
A Start Frame is a specific image you give an AI video tool to use as the very first frame of the generated video, giving you control over exactly how the clip begins.

Cómo se compara
Text-to-video generation interprets a text description to produce a video, giving the model wide latitude over visual decisions including the opening composition. A start frame constrains the model to begin from a specific visual state, significantly reducing variation in character appearance, framing, and environmental detail at the cost of slightly less motion creativity.
Piénsalo como…
Using a start frame in AI video generation is like handing an animator a specific drawing and saying 'begin here' — the animation can go wherever the prompt and model take it from that point, but the first frame is exactly what you intended.
Consejo pro
For character-driven sequences, generate and approve a high-quality character image first, then use it as the start frame for all video clips featuring that character: this produces far more consistent results than relying on text descriptions of the character across multiple generations.
Tipos y variaciones
- Start frames can be supplied from several sources: a previously generated AI image, a photograph, a hand-drawn or painted illustration, a frame extracted from existing video footage, or a rendered 3D still.
- The type of source image affects the visual quality and consistency of the generated output: photorealistic start frames tend to produce photorealistic video, while illustrated or stylised start frames guide the model toward matching that aesthetic.
- Some platforms allow start frames to be combined with style references or ControlNet-style guides for additional control over the generated motion.

- Start frames are used to maintain character appearance across multiple generated clips in a narrative sequence, to begin a shot with a precisely composed still frame before the camera or subject moves, and to animate specific existing images ( photographs, illustrations, or concept art ) into video content.
- In commercial production, start frames from approved concept art ensure generated content matches signed-off design direction without relying on text description alone.
