Instagram supports multiple aspect ratios — 1:1 for feed posts, 9:16 for Stories and Reels, and 4:5 for portrait posts. Zeltor Labs lets you export in any of these formats, automatically adjusting the effect composition for each frame shape. Reels get vertical treatment with centered focal points; feed posts get balanced square compositions.
Best Practices
- 1.Use 9:16 for Reels — this is where music visualizations perform best
- 2.For feed posts, 4:5 portrait takes up more screen real estate than 1:1
- 3.Keep Reels under 30 seconds for optimal engagement
- 4.Use vibrant, high-contrast vibes (Hyperpop, Aggressive) for the feed
- 5.Stories work well for teasers — export the chorus section as a 15-second clip
Export Tips
For Instagram Reels: 1080x1920 (9:16), under 90 seconds, H.264 encoding. For feed posts: 1080x1350 (4:5) or 1080x1080 (1:1). Instagram compresses heavily, so export at maximum quality. Keep file size under 650MB. Use the Hyperpop or Aggressive vibe for maximum visual pop in the feed.
