There’s two different use cases for importing video files to RaceChrono: The first one is to import the embedded data inside the video files to create a completely new session, and the second is to import video files in order to synchronise them to an existing session. The most common issue users are having when importing video files to RaceChrono is selecting a wrong data type for their use case.
1. Importing GoPro sensor data
Select “GoPro sensor data” data type when you want to import the GPS and other sensor data embedded in the GoPro video files and create a new session from this data.
Clicking the Start button will create a new session from the data that is embedded in the GoPro video files. The video file will be automatically synchronised with the new session.

2. Importing raw video files only
Select “Raw video files only” as the data type when you want to import the video files to RaceChrono, and synchronize them to an already existing session.
Clicking the Start button import (just copy) the video files over to RaceChrono’s raw video folder. You can browse the video files in that folder by going to your session’s video list (RaceChrono > Sessions > your session > Videos), and click open the “App storage / Internal storage” tab.
