Protern Video
Video and athlete data, in one tool
An athlete finishes a run. The coach films it on a phone. Before the next start, the clip is on the team's phones.
When the athlete's data is added, speed, lateral force, and splits play on top of the video. Tap the speed graph at the point time was lost. The video jumps to that frame.
The athlete sees what the coach sees
A video reviewed without performance data is open to interpretation. Two coaches can read the same run two different ways. Adding the athlete's data makes the picture concrete. A speed drop is on the graph. Acceleration through the turn is on the path. The time gap is a number.
-
Athlete data on the clipWhen the coach points to where speed was lost, the athlete sees the drop on the graph.
-
Capture during the training dayBig buttons, persistent zoom, auto-save. Built for cold weather and gloved hands.
-
Clips appear without anyone sending themProtern Cloud sends each video to every linked device. The coach films. The team gets the clips.
-
A season's video, searchableMulti-level grouping plus search across multiple parameters. A run from any week of the season is one tap away.
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.
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.
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 component clips do not all need Protern data attached.
-
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.
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.
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
Every Pass includes it. 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, with the data
An Advanced Video file (.protern) carries the video, the athlete's data, and every overlay in one bundle. The recipient opens it in the free Protern Video app and switches overlays themselves. A useful way to send a deeply interactive 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.

AirDrop, Messages, WhatsAppFile-based. No public links.
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.
Custom video properties
Plain text, a single-choice list, a multi-choice list, a number, or yes/no. Bulk assign.
Tag videos with what the team coaches by, like camera position, snow conditions, or drill.
Share the team's properties in one step
One coach sets up the properties. The rest pick them up in one step.
Set up the properties once, send them to the team, every coach uses the same tags.
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
Imported video matches the right athlete using the athlete's data.
Camera footage with timecode lands in the gallery already tagged.
Frame-accurate sync for any video camera
TimeLink is a small device that adds audio timecode to a video camera. The clip syncs to the athlete's data within sub-0.01 seconds. Use a TimeLink whenever you film with a video camera, so the clip works in Protern Video the same way a phone clip does.
-
Athlete actions line up exactly with the dataOn screen, every speed change matches the moment on the graph. Frame by frame.
-
Mix video cameras and phones in one multi-cam runA multi-cam run can combine a video camera (with TimeLink or Protern Clock attached) with phone clips from Protern Video.
-
Works with action cameras and DSLRsAttach a TimeLink to any video camera that records audio. The clip syncs the same way as a phone clip would.
-
Or use Protern Clock instead of TimeLink hardwareRun Protern Clock on an iPhone next to the camera. The same sync accuracy, without buying TimeLink. A budget entry into video camera workflows.

Worth noting
Five things the page has not covered yet
DSQ runs flag themselves
The athlete's data detects the gate miss. One tap from the gallery to the missed-gate frame.
DSQ runs are excluded from benchmark comparisons by default. The fastest reference stays clean.
Multi-cam of any athlete, with or without a sensor
Make a multi-cam of an athlete who is not wearing a Protern Sensor.
Useful when a team is filming competitors at a World Cup race. Their multi-cam runs live in the same library as the team's own footage, so nothing has to be filed elsewhere.
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.
Auto-aligned side-by-side
Pick any two videos. They line up for direct comparison.
The work of matching the playheads is done before the review begins.
Send a deeply interactive clip to a parent
An Advanced Video file opens in the free Protern Video app, no account required.
A .protern file carries the video, the athlete's data, and every overlay. AirDrop, Messages, or WhatsApp it to a parent. They can switch overlays, view side-by-side, even open multi-cam, all without a Protern account.
