Drag simulator is kind of a physical simulation based on vehicle data entered. You can use it to verify your data is sound. It is a tool for users interested in the physical dependencies and rules of power development.

Hi, the lap has the following video associations: <video> <overlaid>false</overlaid> <url>multicam://cloud/GRM-1EB7BCD5-GP</url> <syncPoint>133.970</syncPoint> </video> <video> <overlaid>false</overlaid> <url>file://localhost/LapTimerCapture-20170818-152415.mov</url> <syncPoint>134.200</syncPoint> <...

You will always have some post session work (transfer and re-link), but yes, you will need to sync data and video for action cams not supported. The range of cams supported for the remote controlled / synced scenario are listed in http://www.gps-laptimer.de/compatibility/ios and http://www.gps-lapti...

It looks like you have replaced the original multicam link by a link to a remote video (starting with http://). For this link type, Re-Link is not available. Instead of analyzing what exactly has been done (I ...

The sync point is stored as part of a lap, not a video. It is probably easier to copy the video and use the add video function to add it as a second video to your lap. You can "copy" the sync information by reading the value on phone B and enter it on phone A.

Yes, I have understood. The answer is "You will need to adjust the sync point by +- 1s". Or in other words "No".

Both the startup of internal and external cam recordings suffer from run-time effects that cannot be compensated automatically. At least not easily and without analyzing the content of the video. A delay of 2 seconds however is beyond anything I have seen - at least for automatic (triggered) recordi...

I suggest you have a look into Video Documentation (www.gps-laptimer.de/documentation). It will give you a lot of background information and step-by-step instructions.
