There are three honest tiers of video officiating. VAR needs a broadcast camera array and an offsite review team. Football Video Support (FVS) is IFAB's official cheaper tier, built for competitions that cannot resource VAR, and it still needs a sanctioned competition, a replay operator, and a pitchside monitor. Below both sits the setup most of the game actually runs on: one phone on a tripod with a rolling video buffer, which puts the disputed incident on video for a few seconds of work and no infrastructure at all.
Why grassroots cannot simply "get VAR"
VAR is not one product you buy. It is a synchronised multi-camera feed, a review room, trained video officials, calibrated offside line technology, and a strict protocol governing when a review may even happen. The cost is only half the barrier; the staffing is the other half. A Sunday league, a youth tournament, or a school fixture has one referee, two loud benches, and nobody spare to sit in a review booth.
So the disputed call gets settled the old way, by whoever shouts with the most confidence. That is the actual problem worth solving at this level, and it does not require anything resembling VAR.
Football Video Support: the official cheaper tier
IFAB has been trialling and expanding Football Video Support, a deliberately lighter system for competitions whose human and financial resources rule out VAR. The differences that matter:
- Coaches trigger reviews, not a video room. Each coach gets a limited number of challenges per match, rather than every incident being monitored continuously.
- Far fewer cameras. FVS is designed around a small number of angles rather than a broadcast array.
- One replay operator, not a review team. The operator cues up the footage; the match referee goes to the pitchside monitor and reviews the decision themselves.
- The referee is not pre-warned. Unlike VAR, nobody tells the referee in advance that a clear error occurred. They assess their own call.
FVS is aimed squarely at leagues below the top divisions. If your competition is affiliated and wants video to formally change decisions, FVS is the route to ask your association about. It is the sanctioned answer to "we cannot afford VAR".
Below FVS: what one phone can honestly do
Most football is not played in a competition running FVS either. For that level, the realistic goal is not overturning decisions under a protocol. It is simply having the incident on video at all, so the conversation after the whistle has evidence in it.
The obstacle is that the moment worth reviewing is by definition the one that surprised everyone, so nobody was filming it. You could record the entire match, but then a two-second incident lives somewhere inside two hours of footage, and nobody is scrubbing through that between whistles.
A rolling buffer inverts the problem. The phone continuously holds the most recent 30 to 60 seconds in memory while saving nothing. When a call is contested, one tap writes that minute to a file. You are recording backwards from the tap, which is exactly the shape of the officiating problem.
The sideline setup
- Mount the phone on a tripod at the sideline or end line, high enough to see over heads.
- Open the app and tap Buffer duration. Set 30 to 60 seconds, enough to cover a full possession plus the time it takes for a dispute to reach you.
- Let the game run. The app holds the rolling buffer in memory and saves nothing, so a whole match costs almost no storage.
- A call is contested. Tap once, or trigger the save from an Apple Watch on your wrist without walking to the tripod. The last minute of play becomes a file.
With Save Buffer Only turned on, the app stops and saves by itself after the tap, so you get one clean clip per incident instead of an open-ended recording somebody has to remember to stop.
Where you actually watch the clip, honestly
Video Buffer captures; it has no built-in player. The saved clip lands in Photos, Files, or iCloud Drive, wherever you point Save to, and that is where you scrub it at the sideline. For frame-by-frame review or a side-by-side of two incidents, the companion app Coach Video Analysis does that job; see the guide on analyzing game highlights.
What this is not
Worth being blunt, because overselling this helps nobody:
- It is one angle. One camera answers some questions clearly and leaves others genuinely ambiguous. No single phone resolves a tight offside.
- There is no offside line technology, no synchronised second angle, and no review protocol.
- It does not make video usable to change an official decision. In affiliated competitions, whether a referee may consult video at all is set by the competition rules and the relevant association, not by what technology happens to be on the sideline. Check before you assume. VAR and FVS exist precisely because that permission is formal.
Where it does work: friendlies and training, unaffiliated and recreational leagues, youth and school fixtures, coach and parent disputes, post-match review, and referee self-development, where watching your own calls back is the fastest way to improve. Plenty of officials use it simply to check themselves afterwards, with no dispute involved.
Practical tips from the sideline
- Mount height: chest height or above. A low camera gets bodies blocking bodies; a slightly elevated one keeps the play readable.
- Frame wide: resist zooming in. A disputed call can happen anywhere, so keep the whole penalty area or court in frame and crop with your eyes during review.
- Buffer length: longer is safer for officiating. Sixty seconds covers the play, the reaction, and the walk over to the phone.
- Name your cameras: running phones on two pitches or two base lines? In Save to, give each device its own filename prefix, for example "pitch 1" and "pitch 2", so the clips sort themselves after the tournament.
This is not a hypothetical workflow. Erwin Gierlinger, MSc, coach and clinic educator from Austria, reports: "We used it with the Austrian handball national team at the World Championship in Denmark. I recommend it at every coaches' clinic where I speak."
Do this in Video Buffer Action Camera
The whole sideline setup is one app: a rolling buffer of 2 to 100 seconds set with Buffer duration, Save Buffer Only for one clean clip per incident, Apple Watch as a remote trigger, and Save to with a custom filename prefix per device for multi-pitch setups. Longer buffers are part of the premium subscription; short ones are free to try the workflow.
