About

VellumCG

Features
Read full description

VellumCG is the mobile control surface for live-TV character graphics — lower-third stripes, supers, on-screen credits, phoner boxes, full-frame social/WhatsApp cards, and memorial cards, all aired straight from an iPad or iPhone. It's the companion client to a VellumCG server: the broadcast graphics engine your organization already runs in its control room. VellumCG doesn't replace that server — it puts a fast, focused operator console for it in your hand, so a producer or director can build and air a graphic from the studio floor, a remote truck, or the newsroom without walking back to a desk. FEATURES • Stripe editor — build and air lower-third name/title bars in seconds • Super — full-screen name/title cards for interviews and panels • Credits — on-screen production credits • Phoner — up to three simultaneous phone/remote-guest boxes, slot-based so on-air state stays consistent across every operator • Socials — air X, Facebook, Instagram, LinkedIn, and Truth Social posts as full-frame cards • WhatsApp — pull in and air media shared to your newsroom's WhatsApp workflow • Memorial cards — full-frame tribute cards with photo, rank, name, and title • Playlists — queue and cue graphics ahead of air, then take them live with one tap • Journalist Mode — a self-serve landscape view for on-air talent, with tap-to-air playlist control and a live preview of the actual broadcast output • Bilingual (English/Hebrew) interface with automatic text direction per field • Real-time sync — every change is mirrored instantly to every connected operator and to the live broadcast output HOW LOGIN WORKS VellumCG is server-agnostic, like a workspace-based tool. On first launch you enter your organization's VellumCG server address (its "hub URL") and an operator secret provided by your organization. Every template, playlist, and piece of on-air state is fetched live from that server — nothing is hardcoded to a single broadcaster. Requires a VellumCG server account: this app has no public sign-up, no guest mode, and nothing to explore without one, because it is a professional tool built for TV control rooms, not a consumer app. WHO IT'S FOR VellumCG is built for broadcast operators, producers, and directors running character graphics in a live TV control room — not for general audiences.
