PixVerse v3.5

PixVerse v3.5 generates video from text or images. Its documented controls include several frame shapes, resolution choices and motion modes for developing short visual scenes with a clear action and edit point.

About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

PixVerse v3.5 is a video model for text-to-video and image-to-video creation. A written prompt can establish a new scene, while a supplied image can provide its visual starting point. Use the model to develop a short event with an identifiable subject, motion and final composition.

Begin a text brief with the action the audience should follow. A toy vehicle moving past a stack of books, a character looking up from a desk or light shifting across a room each gives the shot a specific purpose. Add the setting and visual details needed to recognize the subject throughout the sequence.

For an image-led brief, prepare the reference around the subject’s important features. Keep its outline, pose and material details visible, and leave space for the requested movement. Describe how the scene develops from that frame. Retain the original image so the completed motion can be checked against its actual starting point.

The documented catalogue includes landscape, portrait and square frame shapes, several resolution choices and normal or fast motion modes. Choose the controls exposed for the selected workflow and keep their actual values with the result. Evaluate the requested action at the size and shape in which the clip will be used.

Plan a readable ending. A moving subject should finish in a useful position; a reveal should end with the important detail visible. Write this final state into the brief, then inspect whether the generated sequence reaches it. The ending determines how easily the shot can connect to another clip or graphic.

For a stylized scene, describe the visible treatment through color, lighting and materials. Keep the same subject details in the prompt and reference. Check how those details change when the subject moves across the frame or turns into a different view. Use the whole sequence when judging visual continuity.

Review motion, object interactions and timing in the completed clip. Watch for changes in shape, appearance or spatial relationships that affect the scene’s meaning. Inspect the opening and ending alongside the central action. Compare candidates using the same playback size so the choice reflects the destination format.

Save the finished video, prompt, reference and settings together. When a revision is needed, write down the observed mismatch and alter the relevant instruction. Preserve the parts of the scene that already work so the next candidate provides a focused comparison.

Pricing

How the final charge is calculated

The displayed rates estimate the cost before generation. The final charge is calculated from the cost recorded for the original generation. Measured output duration and forecast quantities are not the final billable quantity.

Tariff references do not add request options. Supported parameters are listed for the selected method.

Fast mode
Not specified When fast mode is selected
Flex mode
Not specified When flex mode is selected

Not specified When maximum reasoning effort uses the default adjustment
