Build the page around usable short-form video

Frame it. Price it. Move it.

Prompt-led motion

Describe the scene, direct the movement

Write the scene, movement and visual direction, then use duration and aspect ratio to fit the channel. A fast route from still idea to moving asset.

Image to video

Start from a still, end with motion

Use a still image as the starting frame or visual reference for motion-led content. Product stills become hero clips without a shoot.

Audio with the clip

Synchronised sound in the generated result

Audio arrives with the video rather than as a separate post-production step - ambience, movement and sound land together in one render.

Duration pricing

Every second has a visible price

Clips run from 1 to 15 seconds. Add seconds and the credit meter updates before generation - so a longer cut is a decision, not a surprise.

Quality choices you can compare before running

Resolution and duration choices sit next to their credit cost, so “affordable AI video” is something you can verify - not just a headline.

Spec sheet

The numbers, plainly.

Core use

AI video generation with image input and synchronised audio - realistic motion with strong prompt adherence.

Clip length

1 to 15 seconds per clip, default 8 seconds. The meter shows the cost of every added second upfront.

Resolution

480p, 720p and 1080p output options - compare the credit cost of each before you run the model.

Aspect ratios

Auto, 1:1, 16:9, 9:16, 3:2 and 2:3 - built for short-form social as much as landscape work.

Audio

Synchronised audio generated with the clip - no separate sound pass needed for concept and social work.

Pipeline

Built by xAI. You see one cost: ours - live in the studio before every generation.
