How to keep GPS synchronization throughout the video?

Dealing with non-continuous files

Kinomap is about geolocated videos, meaning a video that perfectly matches a GPS track

When you record a video, you move at a variable speed along with the video recording. 

When you record a GPS track, this is important also to get your speed in order to ensure synchronization along with the video recording. In fact, both your video and GPS contain a time stamp.

• If your GPS track is longer than the video, no issue as it can be re-synchronized once online. Most of us do record the GPS track from the entire ride but capture in the video a part of it.

• If your GPS track is short than the video, it means that part of the video will have no track record.

• If your GPS track hasn’t been recorded at the same time or on the same vehicle as the video, be sure the speed of each device will be quite different so will not match later on.

• If your GPS track has been designed by an app (google maps, route planner on Strava, or other), the file contains only the geographical route but no timestamp or speed. So it will not be useful when uploading a video to Kinomap either.

Some GPS trackers like bike computers give you the ability to pause the GPS recording when you don’t move for some time. Even if the GPS recording is paused, the time flight is on your GPS file so a gap will be added compared to the time stamp on your camera.

How to deal with a pause during your ride?

As explained, we need continuous files from the departure to the arrival, or a section of your ride but continuous. 

If you pause for some time, so pause the camera, and be sure your GPS tracker (watch, Gps app, bike computer) will continue to make the recording, creating a gap between the video when you start again from your pause. In such a case, you have 2 options: 

• Do a complete video recording without pausing the video recorder. Once the ‘master’ video is online, feel free to ask us to make several extracts (part 1 from the start to the first pause, re-start to pause 2, from the last pause to the end). The master video will be switched as unlisted as people can’t really train on it but leave the sections of the video as public. 

• Do a few recordings and upload each section independently. 

To illustrate, let’s take a 2 hours bike ride. When you leave home, you start recording the GPS track and the video recorder (camera). After 1 hour, you pause for 10min, so pause the camera during the pause. at the end of the day, your video will be 2 hours less than 10min long so 110 minutes, while your GPS track will be 120min long. if you upload the 2 files on Kinomap, the video will be well synchronized during the first hour but from minute 60, when you are about to restart the video, having cut the 10min break, but your GPS track will show you staying at the same place for an extra 10min. When your icon will move again on the map, your position on the video will be 10min ahead so no way to keep it synchronized during the second part of your ride.

• If you have kept the video recording during the pause, please upload the entire 120min video and ask Kinomap to create part 1 from the start to the pause (60min long) and then from the end of the pause to the end of the ride as part 2 (50min long)

• If you have to pause the video recording, please upload independently the video in 2 parts, part 1 from the start to the pause (60min long) and then from the end f the pause to the end of the ride as part 2 (50min long)
