Signal Flow Planner for live-event video

Plan a live event's whole video system before you load in. Patch every port from source to screen, see every cable checked against what HDMI, DisplayPort and SDI can carry, and get the signal flow drawing, gear list, cable schedule and Videohub files from the same patch. Built by a live-events video engineer, for the people who patch the room.

The demo is a sample show you can rewire and explore. Supporting is a one-time payment with no subscription, and the calculator and EDID export stay free. Last updated .

In short: the Signal Flow Planner is a browser tool for planning a show's video system. You describe the gear and patch it. It checks each cable, draws the diagram and writes the paperwork, so the drawing, the cable schedule and the equipment order always match the patch.

Questions

What is the Signal Flow Planner?
A browser-based tool for planning a live event's video system. You patch devices port by port, from source to screen. It checks every cable, draws the signal flow diagram, and produces the gear list, cable schedule, cable labels and Videohub files from the same patch.
Is the Signal Flow Planner free?
There is a free live demo: a sample show you can rewire and explore, with nothing saved or exported. A one-time $10 payment, with no subscription, unlocks saving and opening your own shows, the exports and the rest of the Supporter Toolbox. The EDID and video timing calculator stays free.
Does it upload my show?
No. The Planner runs in your browser: nothing is uploaded. Your shows are saved in this browser on your computer, as many as you like, and can also be saved as .signalflow.json files or in one backup file.
Does it work offline?
Yes, for supporters. With PixelTach Offline turned on for your device, the Planner is saved on your computer the first time you open it online. After that it opens and works with no internet at the venue: your saved shows, the checks, the diagram and the PDF, SVG and PNG exports. A small tag in the Planner says when it is ready. Open it online the day before a show: browsers can clear a site's saved data if it goes unused for a long time, and updates wait until you press Reload, so nothing changes mid-show.
Can I share a show or keep versions of it?
Yes, for supporters. Save a named revision at any point (for example v1.1, Issued for load-in), see what changed since any revision, and restore one; the version, date and note can also print in the diagram's title block. To send a show to a colleague, copy a share link or send the show file. The link holds the whole show in the address after the # sign, which browsers never send to a server, so the show is not uploaded anywhere. Opening a link needs the Supporter Toolbox; anyone without it is invited to support first.
How does it check a cable?
It uses the same engine as the PixelTach calculator: exact video timings first, then what HDMI, DisplayPort and SDI can carry at the resolution, rate, bit depth and color format on that cable. When a cable can't carry the signal it says why, for example which SDI link the format needs, or that a converter is missing.
Which devices does it cover, and what does the drawing look like?
It has templates for Barco, Analog Way, Blackmagic (Videohub and ATEM), AJA KUMO, Ross, Christie, Panasonic, Sony (including studio cameras and their CCUs), Roland, PIXERA, Disguise, Millumin and laptops, plus NovaStar and Brompton LED processors and Panasonic projectors, and you can build your own. The diagram prints on ANSI, ARCH or ISO sheets with a title block that can carry your own logo; export it as PDF, SVG or PNG.
