How to Create a Video from Text
Write One Clear Scene
Start with a subject and a visible action. Describe a place, one camera move and the atmosphere. A short scene with a clear beginning is easier to evaluate than a long list of unrelated events.
Set Your Length and Frame
Choose 5–15 seconds and an aspect ratio for your destination. Try a native 480p or 768p draft before committing to a larger output. The displayed credit cost changes with duration and resolution.
Generate and Review
Sign in, submit your prompt and wait for the result in the studio. Check the action and sound before downloading from My Films. You can upgrade your own completed native draft later.
How to Write a Pika Video Prompt
Subject, Action and Setting
Name what the viewer should see and what changes during the shot. “A paper boat drifts through a puddle” gives the model a readable action. Add location and weather only when they help tell that action.
Camera, Light and Sound
Use one camera instruction such as a slow push-in or a fixed wide shot. Add a lighting direction. For the soundtrack, specify ambience or a short musical cue instead of leaving the intended mood ambiguous.
Try This Original Prompt
A paper boat drifts through a rain puddle beside a quiet cafe at dusk. The camera tracks slowly at water level. Warm window light reflects on the ripples. Sound: soft rain, distant cups and a gentle piano phrase.
Text-to-Video FAQ
Do I need to upload an image?
No. Text to Video starts from your written scene. If a specific photograph should set the composition, use Image to Video instead.
How long can my video be?
H3 Flex currently offers whole-second durations from 5 to 15 seconds. Select a shorter clip to test a new idea before rendering a longer version.
Is 4K generated natively?
No. Native outputs are 480p and 768p. Higher-resolution outputs are upscaled. Choose the size that fits your delivery needs rather than assuming it changes the underlying scene.
