Text to Video Model Selection by Input and Output
Choose a text to video model by input type, aspect ratio, duration, audio, cost, and approval needs rather than a generic quality ranking.
Create a text-to-video shot in 3 steps
Turn a clear shot brief into a controlled model test, then approve the complete clip rather than a single attractive frame.
Write the shot brief
Define the subject, action, framing, duration, and details that must remain consistent.
Choose and run a model
Match the input and output controls to the shot instead of relying on a generic ranking.
Inspect the full clip
Review motion, continuity, text, audio, and export fit before using or automating it.
Turn the brief into a model checklist
Start with one silent website loop as the delivery. List its required input, aspect ratio, approximate length, and output format. A clear brief makes model choice more useful than a thumbnail or a broad “cinematic” label. If a specific object or character must persist, decide whether an image reference is required. A text-only route may make a plausible scene but not preserve the approved appearance. The image-and-video handoff page explains that two-stage task.
Read the exact request schema
Open the chosen model page in the video catalog. Note accepted input types, duration choices, aspect ratio, resolution, audio controls, and response handling. Do not copy settings from a different model. Save the model version with the prompt so another team member can reproduce the test. Check live access and run estimate. Price and availability can change by model and settings, so a static comparison table should not pretend to be a current quote.
Use a test set that exposes failures
Use one object interaction: a hand places a labeled box on a table. Review hand shape, box geometry, readable markings, camera movement, and the final frame. Score the result against this brief rather than averaging unlike scenes into one winner. Keep source rights and likeness permissions in the test record. If the output will be public, review content and license separately from model capability.
Choose an operational path
A browser trial is appropriate for visual exploration. An API integration also needs task IDs, retries, output storage, monitoring, and review. The WaveSpeed video guide describes the general platform flow; exact fields come from the model. Select a fallback when a required setting or output quality is absent.

FAQ
Do all WaveSpeed video models use the same fields?+
No. Read each model's own published schema before writing a request.
When do I need image-to-video rather than text-to-video?+
When an approved still or visual identity must guide the moving clip, choose a route that accepts an image.
Does a model ranking replace testing?+
No. A brief-specific sample reveals failures that a general ranking can miss.
What should an integration record?+
Store model/version, prompt, settings, prediction ID, output, cost observation, and reviewer decision.
