For video analysis
Video review with the athlete's data on the run
A coach reviews a run on a phone. Speed, lateral force, and splits play on top of the video. Tap a point on the speed graph. The video jumps to that frame.
Protern Video is a video analysis tool with the athlete's GPS data on every clip. The data attaches to the video automatically. Coaches use the device they already have.
From the start gate to after training
Protern Video covers what a video analysis tool covers. The difference is that the athlete's data plays on every clip, and the team gets each clip in seconds.
Data overlays on every clip
Speed, time, lateral force, and acceleration play on top of the video. Path view, graph view, no-data view.
Athletes named for you, missed gates flagged
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.
Side-by-side that lines itself up
Pick any two clips. They play in sync. The work of lining them up is done before review starts.
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 that lands in seconds
A small, quick-loading copy reaches every coach's phone in moments. The full-quality version follows on Wi-Fi.
Performance data, playing on the run
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, 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.
For more on the overlays and rendered video export, see the Protern Video page.
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 for video camerasA small device that records an accurate audio timecode onto a video camera's audio track, synced to GPS time. Protern Video reads the timecode and lines up the clip with the athlete's data exactly. The camera clip then works the same way a phone clip would.
TimeLink details and the Protern Clock alternative are on the Protern Video page.
Two runs side by side, lined up automatically
Side-by-side is one of the most-used review tools in Protern Video. Pick any two runs and they line up on their own. Speed, lateral force, and the time difference between the runs play on both.
-
Pick two runs with Protern data, they line up on their ownFrom the gallery, the library, or a search result. As long as both runs have Protern data attached, they line up on their own and play in sync from the moment review starts. The runs do not have to be on the same course. No setting, no manual matching.
-
Speed, lateral force, and acceleration on each runThe 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 are still playingA 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 from training pairs with a single-camera run from race day, 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, the athlete's data, and every overlay in one bundle. The recipient opens it in the free Protern Video app and switches overlays themselves.
