Choose Settings by Platform

Platforms differ in the aspect ratio and file format they expect. The default High Quality MP4 preset (H.264, original size, 60 fps) uploads to most platforms as is. In the interface, press ⌥⌘E to open Export Settings and pick the target under Platform Sizes in Resolution.

1. Pick a platform size

Choosing a platform size changes the canvas, and the layout adapts. After turning a landscape recording into a vertical video, use zooms to enlarge the important area.

2. YouTube

YouTube recommends uploading MP4 with H.264 video and 48 kHz AAC audio, at the frame rate the content was recorded in. That is what the default preset produces.

• For higher playback quality: export at 4K before uploading. YouTube uses different bitrate tiers per resolution, and higher resolutions get more bitrate.
• Frame rate: the common frame rates YouTube lists are 24, 25, 30, 48, 50 and 60 fps. For a 120 or 144 fps video, switch to 60 fps before uploading.
• Quality: use High. YouTube re-encodes every upload, and a better source loses less in that step.

3. Short-video and social platforms

• Use a vertical platform size at 30 or 60 fps.
• These platforms recompress too, so keep quality at High rather than choosing Small to save space.
• If there's a file-size limit, lower the frame rate to 30 fps first, then consider HEVC.

4. Chat, email and docs

• Chat and email: use the Web Sharing or Small File preset, or press ⇧⌘C and paste when the export finishes.
• Docs and READMEs: use a GIF for short loops.
