Aspect Ratio Preview
Preview Video Framing for Every Platform Aspect Ratio
Different platforms expect different video shapes. A vertical Reel looks wrong on YouTube, and a widescreen video wastes most of the phone screen on TikTok. The aspect ratio preview lets you switch between formats right inside the editor so you can see the exact framing before you export — no guesswork required.
Available Ratios
9:16 — Vertical
Full-screen portrait format for short-form platforms:
- YouTube Shorts
- Instagram Reels
- TikTok
This is the most common format for mobile-first content. When your source footage is horizontal, the preview shows how the crop will look — including face tracking adjustments if enabled.
16:9 — Horizontal
Standard widescreen format for:
- YouTube (regular videos)
- Websites and presentations
- Desktop and TV viewing
If your source video is already 16:9, this preview matches the original framing. No cropping is applied.
4:5 — Portrait
Tall rectangular format that works well in mobile feeds:
- Instagram feed posts
- Facebook feed
Slightly wider than 9:16 but still taller than square. This format takes up more vertical space in feeds than 1:1 or 16:9, making your content more prominent as users scroll.
1:1 — Square
Equal width and height, designed for:
- Instagram feed (classic format)
- Twitter / X video posts
- LinkedIn video
Square video displays consistently across mobile and desktop without letterboxing on either.
How to Switch Ratios
Find the aspect ratio control
In the editor, look for the aspect ratio button near the preview panel. It shows the current ratio (e.g., "9:16").
Tap to cycle through ratios
Each tap switches to the next available ratio. The preview updates immediately so you can see the new framing.
Check the framing
Play back your video in the new ratio. Pay attention to whether key elements — faces, text overlays, subtitles — stay within the visible area.
Verifying Face Tracking Crops
The aspect ratio preview is especially valuable when you combine it with face tracking. Switching to 9:16 shows you exactly where the auto-reframe crop lands on every frame. You can scrub through the timeline and confirm that the subject stays centered and nothing important is cut off at the edges.
If the automatic crop is not quite right, you can adjust keyframes manually while watching the preview update in real-time.
