Grok‑Imagine‑Video Full Playbook

Four Core Modes

1. Image‑to‑Video (Most Popular Feature)

Upload an image as the starting frame of your video. Focus your prompt on actions, camera movements and ambient sounds, and avoid heavy modifications to people or objects in the original picture.

Prompt Template: Subject actions + camera movement + ambient sound, keep original character appearance and composition unchanged

Example: The character blinks slowly, breeze blows through hair, camera stays static with soft wind sounds. Preserve original composition and facial features.

Great for animating old photos, bringing illustrations to life, creating product clips and dynamic avatar shorts. Imagine‑Video fully unlocks this image‑driven video capability, letting you generate dynamic clips instantly after uploading visuals.

⚠️ Pro Tip: Do not stack too many image‑altering instructions, or characters and objects may get distorted.

2. Text‑to‑Video

Generate complete short videos purely from text descriptions. It delivers native synchronized audio‑visual output: sound effects and ambient audio render together with visuals, no post‑production audio editing required.

Universal Prompt Formula: Subject + actions + scene + camera movement + lighting style + sound details

Example: Sunset over the seaside, teenager running along the beach, slow follow‑shot, crashing ocean waves, cinematic soft lighting, 9:16 vertical format

On Imagine‑Video, you only need a text description to get a ready‑to‑use short video with embedded sound.

3. Audio Sync

Import audio files to align character motions and lip‑sync with your audio input. Perfect for AI voiceover clips and story‑based short videos.

4. Camera Control

Fine‑tune cinematography: slow zoom‑in, horizontal pan, zoom‑out, orbital movement, fixed camera position.

Clear camera instructions greatly boost cinematic quality and prevent dull, static footage.

Parameter Tuning Guide

1. Duration: 6 seconds works best; maximum 15 seconds. Longer runtime costs more credits and raises the risk of visual distortion.
2. Resolution: 480p for fast generation and lower credit consumption; 720p delivers sharper visuals at higher credit cost.
3. Aspect Ratio: 3:2 / 9:16 vertical for social media / 16:9 widescreen / 1:1 square format.
4. Generation Mode: Normal (stable & conservative), Fun (creative & experimental).

Practical Troubleshooting Tips

1. Keep prompts concise. Stick to one subject, one set of actions and one camera motion per generation. Over‑complicated prompts cause incoherent visuals.
2. For image‑to‑video, always add constraints: keep original composition and object appearance to reduce visual artifacts.
3. Explicitly describe sound effects or ambient audio in your prompt if you want generated audio output.
4. Credits will be refunded for failed generations. File upload failures are caused by storage configuration issues and can be resolved after fixing related settings.
