Auto-Captions for X

Twitter videos default to mute. Our AI generates word-level animated captions instantly so your message gets across even without sound.

AutoCut Filler Words

Clean up your demo automatically. DevMotion removes 'umms', 'ahhs', and long silences so your 2:20 minute X limit is packed with value.

High-Res 1080p Export

Don't settle for blurry recordings. Export in crisp 1080p resolution to ensure your code and UI look sharp on every device.

## Frequently Asked Questions

How do I record my screen for Twitter without a watermark?

DevMotion allows you to record and export up to 720p for free without any watermarks. For higher 1080p resolution preferred by X users, you can upgrade to a paid plan.

Does the screen recorder work on Mac and Windows?

Yes, it is 100% browser-based. It works on any desktop OS through Chrome, Edge, or Safari without needing to install an .exe or .dmg file.

Can I add captions to my X video automatically?

Absolutely. Once you finish recording, DevMotion's AI transcribes your audio and generates animated, word-level captions that are perfect for silent scrolling on X.

What is the maximum video length for X?

Free X accounts can upload videos up to 2 minutes and 20 seconds. DevMotion helps you stay under this limit with our AutoCut feature that removes unnecessary silences.

How do I put my webcam in a circle over my screen recording?

When you select 'Screen + Webcam', DevMotion automatically creates a picture-in-picture layout. You can then use the editor to move, resize, or style your camera overlay.
