Frequently asked
What does CaptionLayer do?
It adds automatic captions, trims long pauses and adds gentle zooms. Export MP4 and subtitle files, or plan and automatically publish finished videos to YouTube, TikTok and Instagram with Publish or Studio.
Which social accounts are included in Publish and Studio?
Publish includes 3 connected accounts in total and Studio includes 6. Connect any mix of YouTube channels, TikTok accounts and Instagram professional accounts. For example, one account on each platform uses 3 connections. These are total limits, not a separate allowance per platform.
Can CaptionLayer automatically remove pauses and edit my video?
Yes. In the studio, choose Auto edit to trim long silences and add occasional gentle zooms. Spoken phrases are preserved and subtitle timestamps are adjusted to the edited video. You can review the result and turn auto edit off on a new render to restore the original pacing. Processing minutes are based on the original video length.
How much does it cost?
Mini includes 20 minutes for $5 once; Creator includes 100 minutes for $15 once. We deduct the actual video length, rounded up to the next second. All styles and exports are included, with two free re-renders per clip. Publish costs $39/month including 100 minutes and 3 social accounts. Studio costs $79/month including 250 minutes and 6 accounts. New accounts get 3 free processing minutes.
What files can I upload?
MOV, MP4 and WEBM up to 500 MB and 30 minutes. The video must contain an audio track so it can be transcribed.
Can I add captions to video automatically for TikTok, Reels or Shorts?
Yes. Upload your vertical clip, CaptionLayer transcribes and burns in styled captions, and you export an MP4 ready to post — plus subtitle files if you need them.
Is there an API?
Yes. You can caption videos programmatically with the CaptionLayer API using the minutes on your account, with no extra per-month cap.
