For video analysis
Simple to use, and it does more
A coach reviews a run on a phone before the next one. Two runs play side by side. Three cameras cut together into one top-to-bottom run. Slow motion and frame-by-frame find the moment in the turn.
Protern Video is video analysis built for alpine teams, on the phone, tablet, or laptop the coach already has. Add a Protern Sensor for any athlete, and their speed, time, and line data plays on the video.
From the start gate to after training
Protern Video covers what a video analysis tool covers, and each clip reaches the team in seconds. With a Protern Sensor, the athlete's data plays on the clip too.
Side-by-side on any two runs
Pick any two clips and play them together. Line them up at the start gate, or let a Protern Sensor line them up for you.
Multi-cam from the cameras you brought
Phones, video cameras, DSLRs in one run. The clips merge into a single top-to-bottom view of the run.
A library built for seasons of video
One, two, or three panes side by side. Group by date, course, athlete, or any tag the team uses. Search across every clip in the library.
Sharing in seconds
A small, quick-loading copy reaches every coach's phone in moments. The full-quality version follows on Wi-Fi.
Data overlays with a Protern Sensor
Speed, time, lateral force, and acceleration play on top of the video. Path view, graph view, no-data view.
Athletes named and missed gates flagged, with a Protern Sensor
Clips arrive in the gallery already named to the right athlete. DSQ runs flag themselves. One tap takes you to the moment the gate was missed.
Multi-cam from the cameras you already use
Phones, video cameras, DSLRs, in one run. The clips merge into a single top-to-bottom view of the run, with the camera switching the way it does on a broadcast feed.
-
Phones, video cameras, DSLRs in one runUse whatever filming gear the team has on the day.
-
Multi-cam from any videoThe clips do not all need Protern data attached. The athlete's name and the time the run started are enough to line them up.
-
Switch angles like a TV directorOne main monitor plus two side monitors. Each monitor plays the same run from a different camera, all three at the same time. Click a side monitor to swap that camera into the main monitor, the way a director cuts between angles on a broadcast.
-
TimeLink or Protern Clock for video camerasProtern Video marks every phone clip with the exact time it was filmed. A video camera needs that time added. TimeLink or Protern Clock adds it, so camera clips and phone clips line up in one multi-cam run, and with the athlete's data when they wear a Protern Sensor.
TimeLink and Protern Clock details are on the Protern Video page.
Two runs side by side, before the next one
Side-by-side is one of the most-used review tools in Protern Video. Pick any two runs from the day and play them together. When both runs have Protern Sensor data, they line up on their own, and speed, lateral force, and the time difference play on both.
-
Pick any two runsFrom the gallery, the library, or a search result. Line them up at the start gate and they play in sync. When both runs have Protern Sensor data, they line up on their own.
-
Speed, lateral force, and acceleration, with a Protern SensorThe full set of overlays plays on both sides. Switch overlays the same way you would on a single-run review.
-
Time difference while the runs play, with a Protern SensorA graph shows how far ahead or behind one run is from the other, accurate to a hundredth of a second, while the runs are still playing.
-
Multi-cam runs work side by side tooA multi-cam run pairs with a single-camera run, or with another multi-cam. The two sides do not have to match.

Export the comparison as one videoSave the side-by-side as a single video file. Share on YouTube, in a coach's notes, or in a parent email.
An installed app on every device, online or off
Protern Video is an installed app, not a web page. It runs on iPhone, iPad, Android, Mac, and Windows. Coaches use the device they already have. Reviews start the moment a clip is filmed, with or without an internet connection.
Installed on iPhone, iPad, Android, Mac, and Windows
The same Protern Video on every device. Same overlays, same side-by-side, same multi-cam, same library. Not a website on a desktop only.
Video is on the device that filmed it
Review starts the moment the run ends. The clip plays straight from the phone or camera that filmed it. The upload to the team happens in the background.
Works without an internet connection
Full review on a chairlift, on a plane, in a hotel with weak Wi-Fi. Cloud sharing starts up again when the connection returns.
Review between runs, then again at home
The coach reviews the previous run from the chairlift on a phone. The same review on a laptop after training. The athlete watches their own runs on their own phone.
Sharing and library
Clips reach the people the coach picks, in seconds
The coach controls who sees what. Coaches and athletes on the right list get the clip moments after it is uploaded. The library finds any clip from any week of the season.
Coach-led sharing
Five presets: Private, Individual Athlete, Team, Coaches Only, Custom.
Private is the default. The clip stays with the coach who uploaded it.
Individual Athlete sends the clip to the athlete on the run, plus the coaches.
Team sends the clip to every coach and every athlete on the team.
Coaches Only sends the clip to the team's coaches and no athletes.
Custom lets the coach pick exactly who sees the clip: one athlete and a guest coach, two athletes and a parent, or any combination the moment calls for.
Athletes do not share videos. Sharing always starts with the coach.
Fast version first, original on Wi-Fi
A compressed copy uploads in seconds. The full-quality original follows on Wi-Fi.
A large clip from a video camera is compressed for fast sharing. The team can watch it in moments. The full-quality version uploads in the background once Wi-Fi is available.
Built for hotel Wi-Fi
Uploads survive the app closing, the device shutting down, or the internet dropping.
Hotel Wi-Fi at a race weekend is rarely reliable. The coach does not have to be either. Protern Video picks up any upload from where it stopped, the moment the connection comes back. No restart from zero, and no need to babysit the upload.
Pick when uploads happen
Never, on save, on athlete assign, or on data arrival.
Set the default per phone or computer. A filming phone can upload as soon as a clip is saved. A review computer can wait until the athlete's data is added. Override one video at a time, or a whole batch from the gallery.
Thousands of clips, even on an older phone
Files clear after a set time. The thumbnail and file name stay.
A phone or laptop with little spare space can still browse a 20,000-clip library. Set the clear-out window to 24 hours, three days, seven days, or one month. The video downloads again on tap.
Library search across years
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 multi-season library. Custom properties travel between coaches: one coach builds the team's tags, the rest pick them up in one step.
Send a clip to a parent, a guest coach, or another 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 and switches overlays themselves.
-
Opens without an accountThe free Protern Video app is all the recipient needs. No team link required.
-
The recipient picks the overlayNot a fixed version of the video. The recipient switches between speed, lateral force, path, graph, and the rest, the same as the sender.
-
Side-by-side and multi-cam carry throughThe recipient gets the same review tools as the sender.

With a Protern Sensor, the data plays on the run
When an athlete wears a Protern Sensor, 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, accelerationEach one plays on top of the video. Pick a reference run, and a colour gradient on the run shows where time was won or lost against it.
-
Tap the graph, the video jumpsTap a peak on the speed graph. The video shows the moment that speed was reached. Reading the data and watching the run is one motion.
-
Path view, graph view, no-data viewPath shows where on the course the speed peaked or dropped. Graph plots the speed for the full run. No-data turns the overlays off for teaching: have the athlete describe what they felt, then turn the data back on to compare.
-
Time-difference, by the run or by the sectionPick a reference run. The video shows where time was gained, where it was lost, and by how much.
