Pro Tips For Grok Imagine
Master the art of audio+video prompts
✅ Always Describe Audio
Grok's superpower is audio. Always mention sound in your prompt: "upbeat electronic music," "tense ambient drone," "birds chirping in a forest." The more specific, the better.
✅ Use Audio Cues for Pacing
Describe how sound changes over time: "music starts soft and builds to dramatic crescendo" or "distant thunder getting closer." This creates dynamic videos.
✅ Think Vertically for Social
Use 9:16 aspect ratio for TikTok and Reels. Grok's vertical videos are optimized for mobile viewing and perform better on short-form platforms.
✅ Layer Audio Descriptions
Combine multiple audio elements: "gentle piano music with rain in background and occasional thunder" creates rich, immersive soundscapes.
✅ Test with 480p First
At 24cr for 5s, 480p is perfect for testing prompts. Once you nail the concept, regenerate in 720p for final output.
✅ Create Audio-First Content
Scripts designed for TikTok audio trends work great. Describe trending sounds or emotions: "sad viral audio vibes" or "energetic dance music."
