You're here to
break it.

EFY Streamer is a livestream player for sailboat and powerboat regattas, built around an interactive timeline. These are the rough tools for marking it. We want to know what confuses you, what you'd never use, and what's missing — before any of this gets built properly.

Nothing saves. No accounts. The three tools don't talk to each other. If something looks broken it may well be, and that's worth telling us.

What winning looks like

Every number here goes down, not up. Judge the tools against that.

Fewer hours watched. Nobody should scrub through five hours of a livestream hunting for the moment two boats came together. The timeline takes you straight there.

Fewer thousands spent on editing. An organizer shouldn't need to hire an editor to get a highlight video. The material is already marked by the time everyone's ashore.

Fewer weeks waiting. Not a video that lands next month — one that's ready about an hour after coming off the water, in time for the debrief.

The debrief is the point. Within about an hour of coming ashore, someone stands in front of a room and talks through the day's racing. That hour is the whole constraint, and it's why the marking happens live rather than afterwards: because the racing went out live, the footage already exists and is ready to play back before the boats and the camera crew are off the water.

It puts the excitement of watching live and the convenience of a finished highlight video in the same place.

Who does what

Three levels, and only one of them is required to be there.

Viewers suggestAnyone signed in can suggest a marker. Suggestions appear on everyone's timeline straight away with a pending mark, so the timeline is useful before anyone has moderated it.
Moderators decide what's trueApprove, hide, rename, move. They set the day's first race and the class of boat. They see each other's markers appear live, which stops most duplicates before they happen.
The organizer decides what's goodPins the best of the best for the debrief, adds moderators, uploads and syncs extra camera angles, and locks the final cut.

Live moderation makes the experience considerably better, but it isn't required. Organizers and streamers are stretched thin on race day, so the timeline has to be worth watching with nobody moderating at all.

Read this first, it'll save you ten minutes

Four things that look like faults but are deliberate limits of a prototype.

The built-in demo video is about 17 seconds longIt's a public test stream, not race footage. A whole regatta is squeezed into it, so everything races past. Hit Load footage on any page and pick a race video off your own device — it makes far more sense.
Nothing is savedRefresh the page and everything you logged is gone. That's expected.
The three tools are separateSuggesting something in the viewer will not appear in the moderator view. Each page is its own sandbox.
Powerboat mode is in there tooSwitch sport in the moderator footer and the vocabulary changes — laps instead of legs, and its own fouls. Same five-minute pre-start.
Times are stretched on the short clipSo the seeded race reads at realistic durations. Load your own footage and real timings show through.

What we'd like you to try

Roughly fifteen minutes across all three. Do the viewer on a phone if you can — that's where it'll actually be used.

Viewer

On your phone

Load your own race footage.
Hit Add Marker when something happens. Notice it backs you up six seconds — fix it with the slider.
Log a foul, a mark rounding and an "other" with a note.
Tap a mark in the list to jump to it, then share one.

Open the viewer

Moderator

On a laptop

Load footage, then log a class flag up.
Watch the rest of the sequence appear as dashed guesses, and a countdown to the gun start.
Log the gun, then a windward and a leeward rounding. The legs work themselves out.
Try logging two windward marks in a row and read the warning.

The questions we actually need answered

General reactions are welcome, but these change what gets built.

Does the six-second rewind help or annoy? Every marker backs up six seconds automatically, because you react after the thing happens. You can then drag or tap −1s and +1s to land it. Relief, or an extra step you didn't want?

Does "Suggest Marker" set the right expectation? A viewer's marker goes on everyone's timeline immediately with a pending icon, but doesn't become part of the race until a moderator approves it. Is that obvious from the interface, or does it look like the app is unsure of itself?

Is the marker vocabulary right for your fleet? Sailing: signal flags, mark roundings, finishes, fouls, good sailing, trouble, footage, black flag, other. Powerboat swaps legs for laps and has its own fouls. What's missing, and what would you never touch?

Could you mark a start while also running the cameras? Be honest, because a lot hangs on it. Viewers can only suggest — if no moderator catches the flags and the roundings, the timeline has no race structure at all and everything else degrades.

Is skipping the dead footage right, or too aggressive? Playback jumps everything before the first start, between races, after the last boat finishes, and anything black-flagged. You can't scrub into it and you can't export it. Would you ever want to see it?

Would you run a debrief off this an hour after coming ashore? That's the whole point of the thing. If it wouldn't survive a real room, say what would break first.

What would stop you using this on day one? The thing you'd complain about immediately is worth more than the thing you'd like eventually.

How the marking works

Anyone watching can mark the moment something happens — a port-starboard incident, a capsize, the leader rounding the windward mark. Those marks build the timeline while the race is still running.

You never mark a leg. You tap instants — the class flag, the gun, each leader rounding — and the legs work themselves out. Beat 1, Run 1, Beat 2, however many the course has.

One race, its legs along the bottom, viewer markers rising above it. Nobody typed those legs.

Sending feedback

Tell us the page, what you were doing, and what happened. Screenshots help. "The admin page confused me" is useful; "I couldn't tell which button logged a flag" is far more useful.

Disagreements between testers are the most valuable thing you can give us — where two of you want opposite things is exactly where the design is still undecided.
