Protern Video
Less time on video. More time coaching.
Fifty runs on a training day is about an hour of video work after the skiing: copy the clips, name them, work out whose run each one is, upload, message the athletes. With Protern Video it is one tap per run. The rest happens on its own.
Protern is used by more than 20 national ski teams, and by academies and clubs in more than 25 countries.
Protern Video is from $50 USD per athlete per year, and less as the team grows. Coaches are free.
One tap per run. The admin is gone.
Film the way you do now, on a phone or on the team's video cameras. Name the athlete, and Protern Video takes it from there.
-
Name the athleteOne tap on the phone when you stop recording. From a camera, pick the names on import.
-
The run files itselfBy athlete, date, and course. The whole season stays findable, with unlimited storage.
-
It reaches the athlete, privatelyFilmed on a phone, the run is on the athlete's device before they reach the lift. From a camera, it is there the moment you import.
-
The hour goes back to coachingThe athlete watches the run that night. You pull up last month's run beside today's.
Protern has made our video workflow at ARC remarkably efficient, and it's made us better coaches. The critical data it supplies keeps us focused on the right biomechanics and tactics, maximizing our effectiveness with the athlete.

Filming with a glove on, in cold weather
Protern Video films from the phone coaches and athletes already carry. The interface is built for one-handed use in cold conditions.
-
One-handed cold-weather UIBig buttons. Large zoom dial. A glove can find them.
-
Zoom that stays put between clipsZoom level carries from one clip to the next within a session. No reset between athletes.
-
Auto-save every clipOptional setting. Set it once. Every run is preserved.
-
Filming without an accountA parent or second coach can film without a Protern account. The clips can be shared with the team after.
Tag the run before the next one
After each video, Protern Video asks for the properties you chose. One tap and you're back to filming.
-
One tap per propertyGreat, OK or Needs work. Clean, Straddle or DNF. Big buttons that work with a glove.
-
The athlete's last answer, ready to applyIf the run went like the last one, one tap repeats it.
-
Find those runs tonightFilter the review to every straddle, or every run that needs work.
A top-to-bottom run, like a World Cup feed
Two coaches film the same run from different positions. The clips merge into a single top-to-bottom view of the run, with the camera switching the way it does on a World Cup broadcast.
-
Video cameras, DSLRs, and phones in one runUse whatever filming gear the team has on the day.
-
Multi-cam from any videoAthlete name plus timestamp overlap is enough. The clips do not need Protern data, so a team can build a multi-cam of a competitor at a World Cup race.
-
Switch between angles like a TV directorOne main monitor plus two side feeds. Click a side feed to swap it into the main.
-
Pick the angle that captures the athlete bestAdjust when the multi-cam cuts between cameras. If one shot is obstructed, switch to the camera that caught the athlete cleanly. Editable from any device.
Protern Cloud
Each clip arrives on every device, automatically
Protern Cloud handles sharing inside Protern Video. The coach decides who sees each video. Athletes see only what the coach has shared with them. Once a video is shared, every change to it appears on every device that has access. A parent sees what their child sees, and no more.
What Protern Cloud handles automatically
Configurable upload triggers
Never, on save, on athlete assign, or on data arrival.
Defaults can be set per phone or computer. A filming phone can upload as soon as a clip is saved. A review computer can hold uploads until the athlete's data has been added. Override per video or per batch in the gallery.
Fast version first, original on Wi-Fi
A low-bitrate version uploads in seconds. The original follows on Wi-Fi.
A 150 MB camera clip becomes an 8 MB shareable in moments. The full-quality copy follows once Wi-Fi is available.
Resumable uploads
Survives app close, device shutdown, internet drop.
An upload picks up where it left off. No restart from zero.
Coach-led sharing
Sharing presets: Private, Individual Athlete, Team, Coaches Only, Custom.
The coach controls who sees which video. Athletes do not share videos. Private is the default for everyone, so nothing reaches the team until the coach changes the setting.
View receipts
See who has played each video, and when.
Like a read receipt on a message. You know which athletes are watching, and who to follow up with.
Auto-remove unwatched downloads
Files clear after a set period. Thumbnails and metadata stay.
Browse a 20,000-video library on a 64 GB phone. Set the auto-remove window to 24 hours, three days, seven days, or one month. The video re-downloads on tap.
Unlimited training video storage
Included for every team. No per-coach, per-team, or hours cap.
A full multi-season library has nowhere to fill up.
Updates reach every linked device
A change to a video appears on every device that has access.
A new comparison reference or any update to the athlete's data arrives on every linked device. Athletes see the latest without re-downloading.
Cloud backup for the library
A new device pulls every accessible video on first login.
A lost or replaced device is not a lost library. Reinstall, sign in, the gallery is back.

Send a clip to anyone outside the team
An Advanced Video file (.protern) carries the video in one bundle, with the athlete's data and every overlay when the run has them. The recipient opens it in the free Protern Video app. A useful way to send a clip to a parent, or to a coach outside the team.
-
Open without an accountThe free Protern Video app is enough. No team link required.
-
Recipient switches overlaysNot a single rendered version. The full overlay catalogue, on the receiving end.
-
Side-by-side and multi-cam carry throughThe recipient gets the same review tools as the sender.

Built for a season's worth of video
A full season can be 20,000 clips. Protern Video is built for that scale. Multi-level grouping, custom properties, and broad search let a coach find any clip in seconds.
Find any clip from any week of the season
Multi-pane layouts
One, two, or three panes. Click in one, play in another.
Review and compare without losing place in the library.
Multi-level grouping
Up to three nested groups. Older groups collapse on their own.
Group by date, course, athlete, or any property the team has set up. Match the library to how the team thinks about training.
Properties for each video
Asked after each video you film or import, with one-tap buttons.
Mark a straddle, a DNF or a run that needs work while it's fresh, then find those runs that night or months later. Text, lists, numbers or yes/no. Set a value for every video, or add it later.
One setup for every coach
Decide once how the team works. Every coach imports it in a couple of taps.
A Team Setup File carries the team's camera names, properties, sharing and settings. Each coach sees what will change before anything applies, then gets the same setup as everyone else. Video from every coach sorts and filters the same way.
Find any video by any property
Filter and search across athletes, dates, runs, and any custom property.
Search runs inside multi-cam videos too. Find a clip in seconds, even in a season-scale library.
Athlete auto-detection with a Protern Sensor
Imported video matches the right athlete using the athlete's data.
Camera footage with timecode arrives in the gallery already named.
Film on any camera. Every clip lines up.
Coaches and athletes need to trust what they watch: a multi-cam run that cuts at the right instant and, with a Protern Sensor, the athlete's data on the right frame. Protern Video stamps every clip it films with a time of day accurate to the millisecond. A video camera needs that time added, and there are three ways to do it.
-
TimeLink, for the camera that films all dayA small device on the camera's shoe mount. Twenty hours on its own battery and its own mic, and your phone stays in your pocket.View TimeLink
-
Protern Clock, from the phone you carryThe app sends the timecode to the camera through its mic input. Plug in, press Start, film. On iPhone, iPad, and Android.Get Protern Clock
-
QR Clock, for a camera with no mic inputThe same app shows the time as a QR code. Film the phone screen for a few seconds at the start of each clip. Nothing to plug in.
-
Mix video cameras and phones in one multi-cam runA multi-cam run can combine a video camera (timecoded by TimeLink or Protern Clock) with phone clips from Protern Video.
-
A backup in your pocketTimeLink on the main camera. Protern Clock on your phone for the second camera, or the day the TimeLink stays at home.

Protern Performance
Sensors for the athletes who want them
Any athlete can wear a Protern Sensor and get speed, time, and line data on their video, plus live timing and full run analysis in Protern Performance. Add one athlete or ten, whenever it makes sense for them.
Nothing changes on the day an athlete adds a sensor. Same library, same sharing, same apps. The data starts appearing on their runs, and more of the work happens on its own.
From the speed graph to the video frame in one tap
Once the athlete's data is added, the overlays play on top of the video. Switch them on the fly. Tap any point on a graph to jump to that frame.
-
Speed, time, lateral force, accelerationThe full overlay catalogue. The comparison gradient highlights where time was gained or lost against any reference run.
-
Path view, graph view, no-data viewPath keeps the metric tied to the turn. Graph shows the full run. No-data is for teaching: have the athlete describe what they saw, then turn the data back on to check.
-
DSQ jumps to the gate-miss frameThe athlete's data flags the run. One tap from the gallery to the moment the gate was missed.
-
Path and time-difference viewsSee where on the course time was won or lost compared to the reference. Read it as the run's path on the course, or as a graph.
Every overlay also renders to a single MP4 for sharing on YouTube, Google Drive, or Instagram.
With a Protern Sensor
More of the work happens on its own
The run names itself
The sensor identifies the athlete and the run, so there is nothing to tap.
Run numbers come from the sensor too, so the gallery is in order before review starts.
Side-by-side aligns itself
Pick any two videos. They line up for direct comparison.
The work of matching the playheads is done before the review begins.
Lateral force on the video
Path view ties force to the turn. Graph view shows the full run.
Pinpoint where the athlete builds and releases pressure for technique work.
