Just started playing around with VIRB Edit and first attempt at doing videos with a VIRB Basic.
As a mountain biker my riding is very segment based. One segment for each trail or train section basically. I record the entire ride with my Edge 510 but record video for each individual segment of interest.
If I make a video with just one clip covering one segment and add the data from the 510, I get for example a nice course and altitude overlay just for that clip. If I then add further clips and add the data for each of those, the overlays then show course and altitude covering all the clips. That's kind of useful if I'm focused on the whole ride, but I'm more interested in each segment and would like the overlays to just show the data from that segment in the current clip. So when the next clip in the video takes over, the course (for example) is replaced by just the course data for that segment. It makes it far easier then to see the twists and turns in the course and match to what you're seeing.
If that makes sense.
I'm guessing the only way to do this is to make one video for each segment, then with an external tool concatenate them all together to make a whole video.
Though thinking about it, it might be nice to have a combination. Things like course and altitude showing focused on that clip, but also general ones for the whole ride, all in the same video. Assuming VIRB Edit doesn't support overlays focused just on that clip as an option then that's a suggestion as a nice to have, with the option to have other overlays take the default approach of showing data for the whole ride.
