The NVIDIA eye contact effect — for recorded video
NVIDIA Broadcast's eye contact only works on a live webcam and needs an RTX GPU. CaptionX runs the same NVIDIA Maxine gaze AI on your recorded clips — online, no GPU, any camera or editor.

NVIDIA Broadcast is built for live video — not the footage you've already shot
NVIDIA Broadcast is a fantastic tool for live calls and streaming: it corrects your gaze in real time on your webcam feed in Zoom, Teams, or OBS. But it has two hard limits for creators and editors — it only works live (there's no way to point it at a recorded MP4), and it requires a GeForce RTX or NVIDIA RTX GPU on your machine.
If you've already recorded a talking-head video, a podcast, or an interview and the eye line is off, NVIDIA Broadcast can't help. That's exactly the gap CaptionX fills — the same NVIDIA Maxine model, applied to recorded footage, in post.
The problem
Recorded ≠ live
NVIDIA Broadcast can't process a video file — only a live webcam feed
The barrier
RTX GPU only
No RTX card, no NVIDIA Broadcast eye contact — even for live
The fix
Runs online
CaptionX runs Maxine server-side — any computer, any editor's export

Short version: NVIDIA Broadcast for live calls, CaptionX for recorded video. They use the same Maxine AI — they just solve different halves of the problem.
You're not trading down — it's the exact AI, on recorded footage
CaptionX runs NVIDIA Maxine — the same production gaze-correction model behind NVIDIA Broadcast's eye contact effect. The result is the same natural, subtle gaze redirection; the difference is that it runs on our servers and processes your recorded clip instead of a live camera feed.
