Measure it. Do not guess.
A media gateway and a monitor that run on a machine in your facility and answer with a measurement - and say plainly when they cannot measure something rather than filling the gap with a number.
The heavy work runs on a machine in your facility. Measurements come back; media does not - the one exception is the multiviewer's optional thumbnails, which are off unless you turn them on. The worker dials out on 443 and listens on nothing, so there is no inbound rule to open.
Calculators, measurement tools, reference terms and setups - all of it, in one box.
What can your machine run?
12 of the 17 tools run on an ordinary Linux box with ffmpeg. The five gateways need an ffmpeg built with SRT, RIST or RTMP - and the only way to know about your machine is to ask it.
Three steps to a real measurement
-
Install a worker
One command on a machine in your facility. It dials out to us on 443 and listens on nothing, so no inbound rule and no port forwarding. Workers are free, however many you run.
curl -fsSL https://behub.fc/install | sh -s -- --claim <token> -
Ask it what it can run
The first check is free and costs no credits, ever. It replaces the guess above with what the machine actually reports - the same list every tool's refusal is read from.
Ask a real machine → -
Measure something
You see the price before you press Run, produced by the same code that charges you. A check that fails costs nothing.

18 calculators
The arithmetic, done properly. Bitrate and SDI capacity, ST 2110 bandwidth, timecode and drop frame, MPEG-TS overhead, SRT latency budgets, GOP and segment alignment, loudness correction, aspect ratio, multiplex planning, cable delay.

174 terms explained plainly - the standards, the bodies that write them, and the words people use around you without ever explaining. Plus how it fits together: twelve real arrangements, from contribution and REMI to teleports, OTT and post-production, each ending with what typically goes wrong there.

Version one sells a gateway and a monitor. These are built, tested and working, and are not on the menu yet: file QC and delivery specs, loudness and picture quality, transport analysis, SNMP, NMOS, ST 2110 validation, SCTE-35, EDL conform, and the rest.
See them, and say which you need → One vote per organisation. The counts decide what comes next.What it costs
The calculators and the reference are free and always will be - no account, nothing to install. Beyond that you pay for work actually done, not for servers and not per month.
Workers are free
Installing a worker costs nothing, and keeping it registered costs nothing - however many you have. The heavy work runs on your hardware, so an idle worker costs us a control plane and costs you nothing.
Credits, per action
A one-off check costs a fixed number of credits. A monitor or a gateway costs a small rate per minute while it is running, and stops costing the moment it stops. Some tools, like reading a worker's inventory, are free.
You see the price first
The cost appears before you press Run, and it is produced by the same code that does the charging - so the number you agreed to and the number you are billed cannot drift apart.
A failed check is free
If a job fails, it costs nothing. You are never billed for an answer you did not get.
You cannot overspend
Your balance cannot go negative. A job that could cost more than you hold is refused before it starts, rather than run and invoiced.
Billed on evidence
A running monitor is billed for the time the worker actually reported, never wall clock. A worker that drops off the network stops costing money at the last heartbeat we had, not when somebody notices.
What a credit costs is not published yet. The metering above is built and tested; the rate, the free monthly allowance and whether credits come in packs or with a subscription are still being decided, and we would rather leave the number off this page than put up one we might change.
The measurement tools
What version one offers, what each one does, and what it costs to run. You can read this without an account; running them needs a worker on a machine of your own.
Every one of these runs on your own machine. BE HUB sends the job, the worker does the measuring, and only the result comes back.
Costs above are in credits. Workers are free to install and free to keep; a failed check costs nothing; the price is shown before you run. What it costs has the whole of it.
Version one is deliberately small. 56 more tools are built and not yet offered - they are listed there by name, and you can say which you need.

Eighteen of them, all running in this browser. No account, no upload.
Hover or tap any dotted term for a plain explanation. The same explanations appear everywhere in BE HUB.
Uncompressed video bitrate
What a raw signal actually costs on the wire.
SDI capacity
Which SDI rate carries the signal above, with headroom.
Timecode converter
Drop-frame is handled properly, including the 29.97 and 59.94 skip.
MPEG-TS over IP overhead
Why 1316, and what the wire really carries.
Storage and record time
Loudness targets
Where your measured integrated loudness sits.
ST 2110 stream bandwidth
What an uncompressed IP essence really costs, with RTP overhead.
SRT / RIST latency budget
How much latency a link needs to recover loss, and what it costs.
Jitter buffer sizing
How much buffer a given jitter needs, and the delay it adds.
GOP and segment alignment
Whether your keyframes land on segment boundaries.
ABR ladder and egress
What a ladder costs to deliver at a given audience size.
Aspect ratio and pillarbox
What fitting one shape inside another actually costs.
PCM audio and AES3 capacity
Uncompressed audio bitrate, and how many SDI groups it fills.
Loudness correction gain
The gain to reach target, and whether it will clip.
Frames, time and samples
One frame in milliseconds and audio samples - the conversion behind every sync argument.
Multiplex planner
How many services fit in a fixed-capacity path.
Cable and fibre delay
Propagation delay over distance, in frames as well as microseconds.
Video levels and code values
Narrow versus full range, and where legal limits sit.
Overview
Recent activity
Quick actions
Workers
A worker runs on a machine you own. It dials out to BE HUB and listens on no port, so there is no firewall hole to open.
Add a worker
Run this on the machine. The token is single use and expires in 15 minutes.
Run a check
Pick the machine, pick what to check, see the cost, run it. A check that fails costs nothing.
Recent runs
Monitors
A monitor keeps watching and tells you when something changes, unlike a check, which runs once. Billed by the minute while it is up; stopping it stops the meter.
Alerts
Where to send them
Nothing is sent until you add a destination. Test it before you rely on it.

Version one is deliberately small: a media gateway, a monitor, and the free check that tells you whether either will run on your machine. The tools below are built and tested and are not on the menu yet.
Tell us which you need. One vote per organisation, and the counts decide what comes next - we would rather build the two you will use than the twenty we found interesting.
Broadcast reference
Every term BE HUB uses, plus the wider broadcast vocabulary: the standards bodies, the standards themselves, and the words people use around you without ever explaining them. No account needed.
