Editing the video

[froggy47]

I have a csv file and mp4 file moved from the android phone to race render.

Both have several minutes I need to clip off at the beginning.

I seem to be able to do the video but the data does not get clipped so then they are totally out of sync.

How do I clip them both the same?

Thanks.

The usual way to do this is to first trim the video as you like, and then use the Synchronization Tool on the data input to move it forward to match the time that the video is showing. That will effectively trim the start of the data file in RaceRender, but does it in a more intuitive way for synchronization than you would get with just the normal Trim Tool.

To help this, you can first move the video preview forward a bit until it shows something distinctive that you can later match the data to. Depending on what kind of data you have available, you could use the indicated position on the track map to get your video synchronization within a few seconds, then fine-tune it by looking at the G-force plot. Watch for the G-force to swing from left to right, or vice versa, then match that up with the corresponding moment in your video footage. If your datalogger captures engine RPM or transmission gear, you can also verify synchronization by listening to the audio during a gear change, and comparing that to the timing of the tachometer or the gear indicator. Depending on the datalogger, there may be a slight delay in the RPM and/or gear data, but it should still be reasonably close.

I tried I guess I did it wrong, will try again. Still learning the software.
