Sports & coaching

Multi-angle 4K review, live, without a production truck.

Q: Can the coach pin a different angle than the athlete?

Yes. Tile layout, pinning, and focus are local to each participant.

Q: Does recording affect call quality?

Recording is local and separate from the send path, so it does not consume uplink.

Q: What is the best single upgrade?

A second angle. One extra camera changes more than doubling the resolution of the first one.

Technique lives in the details — foot placement, bat path, a hand a few degrees off. Conferencing video throws exactly those details away. A peer-to-peer room carries every camera at full resolution and lets a remote coach see what a coach standing on the field would see.

Start a call →All use cases

120fps: Negotiated frame-rate ceiling on capable hardware.
3+: Simultaneous camera angles, each with its own tile.
0: Upload wait — the recording is already on your machine.
<1s: Typical glass-to-glass latency with no server hop.

Who this is for

Remote skills coach

Works with athletes in other cities and needs to see mechanics well enough to correct them live.

Performance analyst

Wants clean, high-frame-rate per-angle sources to cut and annotate, not a re-encoded meeting recording.

Club or academy director

Needs a setup coaches can run themselves on existing cameras, with no per-minute platform bill.

The angle you need is the one you cannot see

One webcam from across the gym flattens depth and hides the mechanics that matter.
Compressed conferencing video smears fast motion into mush at exactly the wrong moment.
Reviewing after the fact means uploading huge files and losing the same-session correction.

Where normal conferencing breaks

Meeting tools cap resolution and frame rate, so fast movement becomes unreadable.
Only one camera can be 'the' camera — a second angle means a second meeting or a blurry screen share.
Cloud recordings arrive re-encoded, which is the worst possible source for frame-by-frame analysis.

What 4K Chat brings to it

Every angle is a participant

Wide, side-on, and a detail camera each get their own full-size tile you can pin, focus, and rearrange.

How it works →

High frame rate where it counts

Up to 120fps negotiation on capable hardware, with AV1/VP9 and SVC so motion stays legible instead of smearing.

Local recording at capture quality

Each side records its own source locally, so your analysis source is the original encode, not a cloud mixdown.

Team-room playback

Install as a PWA on the facility's Smart TV and run the review on the big screen with a remote.

How it works →

Same-session correction

Sub-second, server-free latency means a cue lands while the athlete is still in position.

Athletes join from a link

No account and no app store — a phone or a laptop opens the room and is on camera in seconds.

Setting up a session

1
Place two or three cameras
A wide for context, a side-on for mechanics, and a close detail angle on whatever you are actually correcting.
2
Add them as participants
USB cameras and capture cards join as their own tiles; fixed facility cameras will be bridgeable in once IP camera support lands.
3
Bring the coach in
Send one link. Nothing to install, and the coach can pin whichever angle they want independently of everyone else.
4
Record locally for the debrief
Start a local recording so the session file is available for frame-by-frame review the moment you stop.

Gear that works

Action cameras via capture card

A GoPro or similar on HDMI out through a capture card appears as a normal video device and joins as its own angle.

Phones and tablets as roaming angles

The easiest second camera you already own — join from the link and place it where the detail is.

Fixed facility cameras (coming)

WHEP or RTSP cameras mounted in the gym will be admittable as participants once IP camera bridging lands.

Lighting beats resolution

High frame rate needs light. A well-lit 1080p120 angle reads better than a dim 4K30 one for fast movement.

Will this actually work for us?

Will a home internet connection carry three angles?

Adaptive bitrate budgets each angle from available uplink and holds quality down rather than breaking the call. For three 4K angles, plan on a solid wired upload; two angles is comfortable on most home links.

Is the video good enough for real analysis?

The received resolution and frame rate are displayed per tile, so you can verify rather than assume — and the local recording is the original encode, not a re-compressed copy.

Do athletes need an account?

No. They open a link in a browser. The host's plan covers the room.

Can we do team-wide sessions?

Rooms run as a full mesh — every participant connects directly to every other, with no media server. It's built for small groups where quality matters.
