Pika Video Prompt Builder

Build Pika prompts with the right parameters

Pika animates a described scene and accepts a set of parameter flags appended after the text — -ar for aspect ratio, -fps, -neg for a negative prompt and -seed. Getting that flag syntax right matters: a wrong aspect ratio crops your subject, and no seed means you can never reproduce a clip you liked. This builder writes the description and the flags together so you can paste one clean line.

How the builder assembles a Pika prompt

A good Pika prompt has two parts:

1. Description — a concrete scene and a clear motion type (e.g. “camera slowly zooms in”, “subject turns toward the camera”, “gentle wind”).
2. Parameter flags — appended after the description:
   • -ar 16:9 — aspect ratio (16:9, 9:16, 1:1).
   • -fps 24 — frame rate.
   • -neg blurry, distorted — what to avoid.
   • -seed 12345 — fix for reproducibility.

The builder produces, for example:

A koi pond at dusk, camera slowly pushes in, ripples on the water
-ar 16:9 -fps 24 -neg blurry, low quality -seed 12345

Tips for consistent Pika clips

• Fix the seed the moment you get a result you like, then iterate other settings around it.
• Match the platform’s aspect ratio before generating — vertical for Reels/TikTok, landscape for YouTube.
• Keep motion simple. One clear movement (zoom, pan, subject turn) reads cleaner than several at once.
• Use the negative prompt to kill recurring artifacts like “blurry”, “distorted”, “extra limbs”.
• Change one variable at a time so you can tell what each tweak did.
