I have really wanted to be capable of recording video during rides, mostly to capture the unlikey perpetrator of my death. I really hope I'm wasting my money; I don't need to make this an effective investment.
I have purchased two Garmin Virb cameras (rhymes with verb, as in action-word) and mounted one on my helmet and one on the rear rack. I've just really wanted to give these a try.
This is a brief view of the front-camera. No excitement, although an overtaking car does pass me about 1 minute into it.
This is the rear camera from the same ride segment, with the same cars passing.
I learned that I have my helmet cam on the front of the helmet, and that the weight of the camera brings the helmet down to rest on my eyeglass frame - which exerts pressure on my nose in an uncomfortable way. So my next ride I'll have the camera mounted top-dead-center of the helmet.
I like the helmet mount as opposed to a handlebar mount because it shows the rider's perspective. Not that I'm reluctant to mount anything on my handlebars.
It seems like Garmin must be phasing-out this model, the price is down to $99 apiece. With the memory cards and a helmet strap I've got $290 in this.
There's some Garmin freeware that lets you crop the videos and overlay some GPS data. I'd like to learn how to present both the front-and-rear perspectives simultaneously.
Edit to add:
I learned you can do picture-in-picture using iMovie 11 and fortunately my wife K has a MacBook Pro with that software. Here's a look at the car overtaking from behind in the small window (top-left) and then emerging into the forward view:
What does one miss out on, if you purchase the just-obsolete Virb ($99) rather than the Virb Elite ($250)? There are some significant differences. The camera (lens, battery, structure) is the same. The Elite has an on-board GPS to record your ground track, auto-stablization software for your movies, and a software levelling adjustment to calibrate your camera to the horizon (in two dimensions). Also it's got wifi, so when you bring your bike-with-camera into the house you don't have to detach the camera to download the images; they whoosh across the ether with the speed of WiFi.
Small disappointment: while the Virb Edit software will present your movie on your device with an additional map presentation, you can't export the map-in-movie. The map info comes from Google or Bing, and Garmin isn't paying for the IP license. Which I totally get, except for: isn't Garmin a mapping company? Kind of lame for them to say, we don't have any maps especially when they could access the OpenMap project. This is a minor kvetch.
