Caption-x
Automatic captions, silence removal and eye contact fixes for video editors
Caption-x is a captioning and subtitle tool that runs as a panel inside Adobe Premiere Pro and as a browser-based caption studio, with versions for After Effects and DaVinci Resolve on paid plans.
It generates animated captions from your audio, translates subtitles, turns long recordings into short clips and cleans up dead air on the timeline. The desktop app runs on Windows and Mac, and the browser studio needs no install. The company says more than 80,000 editors use it.

What Caption-x does
Captions inside Premiere Pro
Generates animated captions on your timeline from the CaptionX panel, with basic styling included on the free plan. Paid plans add captioning for After Effects and DaVinci Resolve as well.
Browser caption studio
Upload a clip, auto-generate animated captions and export a captioned MP4 without installing anything. It is the option for people who do not edit in Premiere Pro.
Silence Remover
Scans the audio tracks in your sequence for gaps below a dB threshold you set and cuts them in one click. You can set a minimum gap duration so natural pauses stay, preview every detected gap and deselect the ones you want to keep, and choose whether to cut audio only or keep video in sync.
Eye Contact correction
Adjusts a speaker's gaze so they appear to be looking at the camera, applied inside Premiere Pro. The amount of correction time included depends on your plan.
AI Clip Generator
Finds the best moments in a podcast or long upload and turns them into captioned clips in vertical, square or widescreen formats, in the browser.
Translation and subtitle files
Translates subtitles into 89 languages and converts audio to SRT files. Transcription covers video and audio, and the paid plans remove the watermark from exports.
