To change video aspect ratio in Envizion AI, click the ratio button in the toolbar and select your target — 16:9 for YouTube, 9:16 for Reels/TikTok, or 1:1 for Instagram. AI Smart Reframe automatically repositions subjects to prevent awkward cropping.
# How Do I Change Video Aspect Ratio?
Every platform has a preferred aspect ratio. YouTube wants 16:9, Instagram Reels and TikTok need 9:16, and Instagram feed posts work best at 1:1 or 4:5. Envizion AI lets you switch between ratios instantly and uses AI to keep your subject centered.
| Ratio | Resolution | Platform |
|-------|-----------|----------|
| 16:9 | 1920x1080 | YouTube, websites, TV |
| 9:16 | 1080x1920 | Reels, TikTok, Shorts |
| 1:1 | 1080x1080 | Instagram feed, LinkedIn |
| 4:5 | 1080x1350 | Instagram portrait |
| 21:9 | 2560x1080 | Cinematic ultra-wide |
1. Open your project in the Envizion AI editor.
2. Click the aspect ratio button in the top toolbar — it shows your current ratio (e.g., 16:9).
3. Select your target ratio from the dropdown. The canvas resizes immediately.
4. Enable AI Reframe (optional) — The AI analyzes each clip and repositions subjects to stay centered in the new frame. This prevents awkward cropping where heads are cut off.
5. Manual adjustment — Click any clip and drag to reposition it within the new frame if the AI placement needs tweaking.
6. Export — Your video renders at the selected ratio and resolution.
Envizion AI's smart reframe feature tracks faces and key subjects across every frame. When you switch from 16:9 to 9:16, the AI automatically pans and crops to follow the action. This saves hours compared to manually keyframing each clip.
A powerful workflow is to edit once in 16:9, then duplicate the project and switch to 9:16. The AI reframes everything automatically, so you get a YouTube version and a Reels version from a single edit session.
It depends on the ratio change. Going from 16:9 to 9:16 requires cropping the sides. Envizion AI's smart reframe ensures the most important content stays visible.
Yes. Click "Custom" in the ratio dropdown and enter any width-to-height value. This is useful for digital signage, presentations, or non-standard displays.
Only indirectly. A 9:16 video at 1080x1920 has the same pixel count as 16:9 at 1920x1080, so file sizes are comparable at the same bitrate.
