## Frequently Asked Questions

How do I add captions to a LinkedIn video without a watermark?

DevMotion allows you to export 720p videos with AI captions for free without any watermark. For 1080p or 4K professional exports, you can upgrade to a Creator or Pro plan.

Does LinkedIn automatically generate captions for uploaded videos?

LinkedIn has basic auto-captions, but they often lack accuracy and styling. DevMotion provides word-level animations, custom brand fonts, and emoji support that LinkedIn's native tool doesn't offer.

What is the best video aspect ratio for LinkedIn ads and posts?

For the LinkedIn feed, 1:1 (square) or 4:5 ratios perform best on mobile, while 16:9 is standard for desktop. DevMotion lets you resize your video and adjust caption placement for any format.

Can I edit the AI-generated transcription if there is a typo?

Yes, our editor includes a full text-sync timeline. You can click on any word to correct spelling, adjust timing, or change the emphasis of specific phrases.

Does DevMotion support technical B2B and medical terminology?

Our AI is trained on diverse datasets, making it highly capable of transcribing industry-specific jargon, making it ideal for founders and recruiters in tech or healthcare.
