[OSM-talk] video mapping

Hello Peter,

I’ve done quite a bit of video mapping in the past, with just manual moving the map around to do the editing. I have since discovered that taking photos and using Mapillary can produce much better results as you can zoom into the images much more thus being able to see details better. There is the caveat in that the taking of photos every 2 seconds can mean missing out on something between 2 frames, however I’ve not found this to be a huge issue, as the 1080p video would be less clear, thus would possible not be able to read it anyway. Sharing of the photos is also easier, which means other people can map things that I’ve not noticed or aren’t interested in mapping.
