Video and timing,right at the course side.
LinePaddle films every run, times it sector by sector and files it under the athlete's name.
1 · Training
The session, from the course to the analysis.
Every run is filmed, the time lands in the right sector, and the video is filed under the athlete's name.
A session
From the call-up to the videos being sent.
Six steps, in the order they happen. The coach keeps their eyes on the water; the app files the rest.
The session appears in the group calendar. Each athlete answers with one tap, with their boat for the day.
The iPhone or iPad camera, stabilised. The clock starts with the athlete; +2, +50 and DNF are tapped during the run.
The name is given after the take, among those present. The run is deduced; the time and penalties follow the video.
Sectors are defined by ranges of gates. Each split comes with its gap to the best run.
By run, by category, by athlete or as gaps. The fastest in neon, the slowest in red.
Each file carries the athlete, the run, the sector and the time. Everything uploads to the group Drive in the background.
The table
The same table, from iPhone to Mac.
By run, by category, by athlete or as gaps. A cell opens the video of that run; two cells compare.
Example results. The video is a real S2 run, in Pau.
Analysis
Two runs, one clock.
Both videos start from the same instant of the clock: the gap reads sector by sector.
App screenshots: at the start, then at gate 4. Above each video, the sector times and the gap to the other run.
Ghost
Run B is overlaid on A, see-through.
Drawing and slow motion
A line drawn on the picture; both videos stay in sync frame by frame.
Export
The split screen is saved as one video to send.
As a team
Several coaches, one session.
Each coach covers a station on the course. Videos and times come together in the same session, on the group Drive.
Shared session
Join the current session with one tap; the device that created it sets the athletes and boats.
Stitched runs
Optionally, the sectors of one run are joined into a single video, in the background.
For the athlete
Their videos, their times, their training log, shared with the coaches they choose.
2 · Competition
Races, slalom and kayak cross.
Race files with the official videos, and kayak cross followed heat by heat.
Races
Official race videos, split by sector.
One folder per race. Sectors are defined by ranges of gates; each imported video creates its own row, named from the file. The table can be followed live with a code.
Example results. A cell opens the video, cued to the start of the sector.

Where do the videos go?
