Youtube video processed with GoPro Quik and MP4Joiner:

Youtube video processed with RaceRenderer:

It takes a long time to render a video for youtube. I timed myself once. It is about five hours on a good day. It takes about twenty minutes to transfer close to 23 gigabytes of video. To make matters worse, GoPro records in chapters that are about 3.97 gigabytes long. The 78-minute video is five chapters.

It is not easy to create a long video. The tools for stitching the videos together with gauges and telemetry is lacking. If I create the video with GoPro’s Quik, I have to first turn on the gauges that I want, then create a clip. Lastly, I use a program called mp4joiner.

Another option would be the preferred Dashware. Problem with Dashware is just not supported. It does not extract the telemetry data properly.

I am currently trying out RaceRenderer. What is good about it is that it does join the videos, extract the telemetry properly and saves a CSV for later analysis. It has plenty of gauges. Problem is, I like the look of the gauges from GoPro’s quick better. Well, you can’t have it all.

If my team likes RaceRenderer better, I might just go forward. I have done the work for the template. It just might make it easy on me to get the job of processing the videos.

If you have an oppinion about the two methods, let me know in the comments.
