Exporting Videos from ZoomArc

To export, click Export (or press Ctrl+E) in the editor, then choose where to save. Pick the format, quality, resolution and aspect ratio in the editor header first. Exports run in the background, so you can keep editing or switch to another take.

Exporting with a transparent background

A transparent format only keeps transparency the background already has — you need both:

1. Set Background → Transparent. The preview shows a checkerboard behind the areas that will be see-through.
2. Choose a transparent format: MOV, WebM (transparent), MKV or PNG sequence. (Turning the background transparent switches you to MOV automatically.)
3. Click Export.

ZoomArc helps you avoid the two common mistakes:

• Pick a transparent format while the background is still solid → the header shows "Background isn't transparent" with a one-click Make transparent button.
• Export a transparent background as MP4 or regular WebM → ZoomArc asks first, because those formats would turn the background black.

Checking the result: Windows' built-in video players often show a MOV's transparent areas as black, even though the file is transparent. Check it in DaVinci Resolve, Premiere Pro, After Effects or OBS — or export WebM (transparent) and open it in Chrome.

In Frame mode the recording grows to fill the canvas while zoomed, so there's no transparent margin during zooms. Use Video mode to keep the margin throughout.

Quality (MP4 and WebM)

Preset	Use it for
Lossless (default)	Maximum quality, largest files
High	Visually lossless, much smaller
Balanced	Everyday sharing
Smaller file	Email, chat, quick previews

MOV and MKV are always lossless.

Resolution and aspect ratio

• Resolution: Source resolution, 1080p, 1440p or 4K UHD — named after the short edge, so 1080p in 9:16 is 1080×1920.
• Aspect ratio: Source, 21:9, 16:9, 16:10, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 10:16, 9:16.

Destination	Suggested settings
YouTube / website	16:9, 1080p or 4K, MP4 High
YouTube Shorts, Instagram Reels, TikTok	9:16, 1080p, MP4 High
LinkedIn / X feed	1:1 or 4:5, 1080p, MP4 Balanced
Video editor (Premiere, Resolve)	Source, MOV (ProRes 4444)

What's included

Exports are rendered frame by frame at 60 fps with exactly the same engine as the preview — zooms, cursor (including custom cursor images), click highlights, backgrounds, text, shapes, images, webcam and microphone audio.
