Will changing aspect ratio crop my video?

Going from wide to tall requires cropping the sides. Envizion AI smart reframe keeps the most important content centered automatically.

Can I use a custom aspect ratio?

Yes. Click Custom in the ratio dropdown and enter any width-to-height value for signage, presentations, or non-standard displays.

Does the aspect ratio affect file size?

Only indirectly. Same pixel count at the same bitrate produces comparable file sizes regardless of orientation.

How do I change the aspect ratio without losing quality?

To change the aspect ratio without losing quality, use Envizion AI's smart reframe feature. This tool uses AI to track and center subjects while adjusting the aspect ratio, ensuring that the most important parts of your video remain in focus. Start by selecting your desired aspect ratio from the dropdown menu, then enable AI Reframe. The AI will automatically reposition subjects to fit the new frame, minimizing quality loss and avoiding awkward cropping.

What is the best aspect ratio for social media videos?

The best aspect ratio for social media videos depends on the platform. For Instagram Reels and TikTok, use 9:16 (1080x1920). Instagram feed posts work best at 1:1 (1080x1080) or 4:5 (1080x1350). YouTube and most websites prefer 16:9 (1920x1080). Using the right aspect ratio ensures your videos display correctly and look professional on each platform.

Can I change the aspect ratio of a video on my phone?

Yes, you can change the aspect ratio of a video on your phone using various apps. Envizion AI offers a mobile-friendly interface that allows you to adjust the aspect ratio easily. Open your project, tap the aspect ratio button, and select your desired ratio. The AI will automatically reframe your video to keep subjects centered, making the process quick and efficient.

How do I fix the aspect ratio of an old video?

To fix the aspect ratio of an old video, import it into Envizion AI and use the aspect ratio tool. Select the desired ratio from the dropdown menu and enable AI Reframe. The AI will analyze the video and reposition subjects to fit the new frame, ensuring that important content remains visible. This process helps modernize old videos for current platform standards.

What aspect ratio should I use for YouTube videos?

Use the 16:9 aspect ratio for YouTube videos, as it is the platform's preferred format. This ratio, with a resolution of 1920x1080, ensures your videos display correctly and look professional on YouTube. Envizion AI can help you easily switch to this aspect ratio and use AI to keep your subjects centered, optimizing your videos for the best viewing experience.

# 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.

Common Aspect Ratios

| 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 |

How to Change Aspect Ratio

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.

AI Smart Reframe

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.

One Project, Multiple Ratios

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.
