The record

Product: dfine.io Review combines media uploads, review, approvals, conferencing and livestreaming in one browser tab.
Frame-accurate review: Reviewers can comment on the exact timecode and add annotations and notes.
Sharing: Share links can have password, expiry and download controls, and guests can upload without an account.
Versioning and audit: New file versions stack on the existing file, and an optional per-share audit trail logs views, uploads and downloads.
Live sessions: Conferencing uses one shared playhead, and browser livestreaming supports up to UHD.
Livestream protocols: The site describes RTMPS at sub-one-second latency and WHIP with roughly 30 to 50% lower latency and 1:1 passthrough.
Editing integrations: dfine.io Desktop streams Adobe Premiere Pro and DaVinci Resolve into browser review through native plugins.
Reference monitoring: dfine.io Playout sends the live signal to a DeckLink output described as color-accurate and frame-synced.
macOS app: The Desktop download page lists Apple Silicon and Intel macOS 15+ builds as coming soon, and states there is no Windows build.
