Text-to-video prompt tips
Lead with the subject and action
“A street drummer plays on an upturned bucket at dusk” gives the model the who and the what before any style words.
Name the camera move
Dolly-in, handheld follow, slow orbit, static wide. Camera directions are guidance rather than exact control, so keep them simple.
Quote the dialogue
Put spoken lines in quotes and say who speaks them. Short lines sync better than long monologues inside a 5-second clip.
Iterate at 480p or 768p
Those are the native resolutions. Lock the idea there, then re-run the winner at 1080p, 2K or 4K, which are upscaled.
Split long stories into shots
Clips top out at 15 seconds. For longer pieces, generate several shots and cut them together in an editor.

It is the prompt-only mode of Pika H3 Flex: you describe a scene and the model generates a 5–15 second, 24 fps clip with synchronized stereo audio, without any input image.
Does text to video include sound?
+
Yes. Dialogue, music, sound effects and ambience are generated in the same pass as the frames, so you do not need a separate audio tool for a first cut.
How long can a prompt be?
+
Up to 2,000 characters on this site. The open-weight CLI accepts up to 8,000, but focused prompts of a few sentences usually work best.
How fast is it?

Pika reports that a 15-second 768p clip can take as little as about seven seconds of transformer compute on its hosted stack. End-to-end time on this site includes queueing, upscaling and download, so expect it to be longer.
How much does a text-to-video clip cost?
