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.
