Aspect Ratio

Learn how to choose Auto, 16:9, 9:16, 1:1, 4:3, or 3:4 in CANVID, and how aspect ratio affects padding, cropping, and export size.

Use Aspect Ratio when you want your CANVID project to fit a specific platform, layout, or viewing format. You can keep CANVID on Auto, or choose a fixed frame such as 16:9, 9:16, 1:1, 4:3, or 3:4 before exporting.

How to Change Aspect Ratio

Open a project in the editor

Finish a new recording, or open an existing project.

Find the aspect ratio control

In the Editor preview controls, look near the Crop button for the aspect ratio button. It shows Auto by default, or the currently selected ratio.

Choose a ratio

Open the menu and select Auto, 16:9, 9:16, 1:1, 4:3, or 3:4.

Preview the result

Review the preview before you export. The selected frame is what CANVID uses for the final exported video.

How Auto Works

Auto is the default setting. When Auto is selected, CANVID adapts the project frame to the recording's current visible area.

That means Auto can respond to edits that change the visible shape of your video:

  • Cropping changes the visible area of the recording.
  • Padding changes the space around the recording.
  • When the aspect ratio is set to Auto, adjusting padding can automatically change the project aspect ratio.

Use Auto when you want CANVID to calculate a natural frame around your recording and background styling.

If you need the video to stay in a specific shape for a platform, choose a fixed aspect ratio instead of Auto.

Fixed Aspect Ratios

Fixed aspect ratios keep the project frame in the selected shape. Padding can still change how much space appears around the recording, but the overall frame remains locked to the ratio you chose.

  • 16:9: Best for YouTube, websites, standard video players, presentations, and most landscape screen recordings.
  • 9:16: Best for vertical mobile video, including YouTube Shorts, Instagram Reels, TikTok, and stories-style formats.
  • 1:1: Useful for square social posts, Instagram feed posts, LinkedIn posts, and compact demos that need equal width and height.
  • 4:3: Useful for older presentation layouts, classroom materials, and landscape formats that should feel less wide than 16:9.
  • 3:4: Useful for portrait layouts that need more width than 9:16, such as vertical walkthroughs or mobile-focused documentation.

Cropping, Padding, and Export

Cropping and padding are closely related to aspect ratio:

  • If you crop first, the visible shape of the recording can change.
  • If you use Auto, CANVID recalculates the project frame from the recording, crop, and padding.
  • If you use a fixed ratio, CANVID keeps the project frame in that ratio.
Cropping can change your video's final resolution. For the cleanest result, crop first, then choose the aspect ratio you want before exporting.

When you export, CANVID uses the current project frame. The export Resolution setting controls the vertical pixel height, such as 720p, 1080p, 1440p, or 4K for MP4. The exported width is calculated from the current aspect ratio so the saved file keeps the same shape you previewed in the editor.
