Aspect ratios: which one for which platform?
AITuber makes videos in three aspect ratios: vertical 9:16, landscape 16:9, and square 1:1. Pick the ratio in the create form to match the platform you post on. The default is 9:16.
Which ratio does each platform want?
Ratio | Shape | Best for |
|---|---|---|
9:16 | Vertical | YouTube Shorts, TikTok, Instagram Reels |
16:9 | Landscape | YouTube, Twitter/X, LinkedIn |
1:1 | Square | Instagram and Facebook feed posts |
Can I use every ratio with every video type?
Almost. The square 1:1 ratio works with AI images and stock footage only. AI video clips support 9:16 and 16:9. If you need square AI video, generate with images instead.
What resolution do I get?
Videos generate at Full HD:
Ratio | Generation resolution |
|---|---|
9:16 | 1080 x 1920 |
16:9 | 1920 x 1080 |
1:1 | 1080 x 1080 |
When you download, you choose the export resolution:
- 1080p (default): Full HD. Fast rendering.
- 4K: Ultra HD (3840 x 2160, or 2160 x 3840 for vertical). Slower rendering, larger file.
How to download your video for the export steps.
Can I change the ratio after generating?
No. The ratio is fixed when the video generates, because every image and clip is made at that shape. To get another ratio, create the video again with the new ratio selected.
