Video captions arrive on iOS. Android gets video transitions between clips. Video transitions are easier to find in the web editor, and smoother developer workflows arrive in our documentation across platforms.

Let’s dive in!

Add Video Captions on iOS #

Generate captions automatically, add them manually, or import a caption file. Then style them with presets and controls for font, formatting, color, stroke, and rounded backgrounds. Customize the presets to match your users’ needs.

Tip: The iOS video starter kit makes it faster to add a complete video editing experience to your app.

Add Video Transitions on Android #

Make videos feel more polished with built-in video transitions, now available directly in the Android editor timeline.

Tap the transition icon between two clips to preview and apply effects without leaving the editing flow.

Apply transitions to a single clip pair or across all your clips. This makes it faster to create smooth video clips with less manual work.
