Before you press record
Six things decide how well the skier can be tracked.
- 1080p at 60 fps. At least: 60 frames per second, in full HD or better. 4K helps a lot if the phone has it.
- Whole body in frame. From the first gate to the last, skis included.
- Stand still, turn to follow. Turning to follow the skier is fine. Walking isn't.
- One run per clip. Between 10 and 60 seconds.
- Keep it sharp. A sharp, high-resolution clip tracks far better than a soft one.
- Send the original. WhatsApp and iMessage compress the video and tracking suffers.
Where to stand
Risegate works from a flat image, so it only sees movement across the picture. Pick the view for what you want to work on.
Set the phone to 60 fps
On an iPhone: Settings, then Camera, then Record Video. Pick 4K at 60 fps, or 1080p at 60 fps if space is tight. On Android, the frame rate is in the camera app's video settings.
Get the file across
AirDrop, a cable or the Files app keep the video as it was filmed. Messaging apps like WhatsApp, iMessage and Instagram shrink it first, and the skier gets harder to track.
