You could try manually setting the Start/Finish point with:
- Select your data file in the Input Files in the top right
- Click Config
- Click "Set Start / Finish Point" button next to Lap Number in the pop-up
- Move the slider to approximately where the start/finish is
- Click OK
Hopefully that will then allow RaceRender to go calculate the lap times for you.
If you have official timing, then you could just enter them one-by-one by clicking the Laps button next to Create Video, and then entering each lap with the format (where lap 0 is any time prior to crossing the start/finish the first time):
Code:
Lap 000: 00:00:18.204
Lap 001: 00:00:50.436
Lap 002: 00:00:51.267
Lap 003: 00:00:52.148
Lap 004: 00:00:50.845
Lap 005: 00:01:39.470
Lap 006: 00:00:50.156
Lap 007: 00:00:50.585
