A method for remote selection of a section in a video file with a mobile device , comprising the steps of: - recording a video file encoding a video with a camera , - sending the video file to a server system , - storing the video file associated with a video file time reference from a time reference system of the camera , and an event identifier associated with the video file, - receiving a user input on a mobile device, wherein upon user input an electronic highlight-marker is generated on the mobile device , wherein the electronic highlight-marker comprises a highlight time defining a time segment based on a time reference system of the mobile device , and an event identifier, - sending from the mobile device the electronic highlight-marker to the server system , - synchronizing the time reference of the video file and the highlight time of the highlight-marker to a common time reference system, - selecting a highlight section of the time-synchronized video file, wherein the highlight section of the time-synchronized video file comprises that part of the video that has been recorded simultaneously with the time-synchronized highlight time, - playing back a highlight-video, wherein the highlight-video comprises the highlight section of the time-synchronized video file, wherein the video file and the highlight time are synchronized in time by the steps of: - determining a camera offset time between the time reference system of the camera and the server system , - determining a mobile device offset time between the time reference system of the mobile device and the server system , - offsetting the video file time reference by the camera offset time and the time reference of the highlight time of the highlight-marker by the mobile device offset time such that the time reference of the video file and time reference of the highlight time are time-synchronized to the time reference system of the server system . - recording a video file encoding a video with a camera , - sending the video file to a server system , - storing the video file associated with a video file time reference from a time reference system of the camera , and an event identifier associated with the video file, - receiving a user input on a mobile device, wherein upon user input an electronic highlight-marker is generated on the mobile device , wherein the electronic highlight-marker comprises a highlight time defining a time segment based on a time reference system of the mobile device , and an event identifier, - sending from the mobile device the electronic highlight-marker to the server system , - synchronizing the time reference of the video file and the highlight time of the highlight-marker to a common time reference system, - selecting a highlight section of the time-synchronized video file, wherein the highlight section of the time-synchronized video file comprises that part of the video that has been recorded simultaneously with the time-synchronized highlight time, - playing back a highlight-video, wherein the highlight-video comprises the highlight section of the time-synchronized video file, - determining a camera offset time between the time reference system of the camera and the server system , - determining a mobile device offset time between the time reference system of the mobile device and the server system , - offsetting the video file time reference by the camera offset time and the time reference of the highlight time of the highlight-marker by the mobile device offset time such that the time reference of the video file and time reference of the highlight time are time-synchronized to the time reference system of the server system . <EOS>
