Grok Video AI Remix | Video to Video with Audio

About this model

Fast xAI model for short Grok image-to-video, text-to-video, and video remix clips with automatic audio.

When is this model useful?

Grok Imagine Video works best when you need a short clip with sound fast and want one model for image animation, prompt generation, and source-footage remixing.

Best fit tasks

Grok image-to-video generation for product shots, portraits, illustrations, thumbnails, and campaign frames that need motion plus automatic sound.
Text-to-video concept generation for ads, social clips, short explainers, storyboard tests, and fast visual exploration from a plain-language prompt.
Grok video AI remix work for short existing footage when you want to shift the mood, style, or visible details of a shot through prompt guidance.
Fast creative iteration when a team needs to test ideas quickly and get a clip with sound without a heavy post-production workflow.

Main advantages

One model covers three common workflows: text-to-video, image-to-video, and video-to-video, so the same Grok page cluster can support prompt, image, and remix intent.
Audio is generated automatically together with the visuals, so ambience, effects, and the overall feel of the scene are present from the start.
It supports short clips from 1 to 15 seconds, common aspect ratios, and two practical output tiers: 480p and 720p.
Pricing is easy to predict on AISVIT because the current integration uses a fixed 5 credits per second rate whether you start from text, an image, or a source video.

Limitations to know

This model is built for short clips, and the video editing route is limited to source footage up to 8.7 seconds.
In this integration, output is limited to 480p or 720p, so it is not the route for the highest-detail or long-form production work.
Tiny on-screen text, complex hand motion, crowds, or long chains of tightly choreographed actions can still drift, so shorter and clearer scenes usually hold together better.
When you add an image or edit an existing video, frame shape and duration are influenced by the source media, so control is less flexible than in pure text-to-video generation.
For image-to-video, a clear single subject usually works better than a crowded image. For video remixing, short clips with one main action are easier to control.

How to use this model

Start with one clear scene idea: describe what should happen, then choose whether the Grok workflow should begin from text, a still image, or a short source video.

Simple workflow

Write the prompt in plain language and describe the subject, action, setting, visual style, camera movement, pacing, and any important sounds the scene should imply.
For text-to-video, choose duration, aspect ratio, and resolution. For first tests, 5 seconds at 720p or 480p is usually enough to validate the idea quickly.
Use image-to-video when the first frame needs to match a specific product shot, portrait, illustration, thumbnail, or composition.
Use video-to-video remix when you already have a short clip and want Grok to change the style, atmosphere, or visible details with a prompt.
Because sound is created automatically with the video, mention ambience, environmental noise, music, or spoken lines in the prompt when they matter.

Prompt patterns

Grok remix: upload a short source clip, ask for one style or mood change, and keep the original action easy to recognize.
Image animation: upload a clean product or portrait frame, describe one motion and one sound cue, then test 5 seconds before trying a longer clip.
Text concept: start with subject, action, setting, camera, and sound in one compact sentence, then use 720p when the idea is ready for review.

Supported inputs

Required: a text prompt.
Optional: one image in JPG, JPEG, PNG, or WEBP for image-to-video animation.
Optional: one source video in MP4, MOV, or WEBM for video-to-video editing; the raw model schema limits source video to about 8.7 seconds.
For text-to-video and image-to-video, you can choose a duration from 1 to 15 seconds.
Available aspect ratios: 16:9, 4:3, 1:1, 9:16, 3:4, 3:2, and 2:3.

What you get

A generated MP4 video file.
Video with automatically synchronized audio generated together with the visuals.
Available output resolutions: 480p or 720p.
For text-to-video and image-to-video, a short 1 to 15 second clip; in video-to-video, duration usually follows the source footage.
