1) The video lacks contrast. It is almost like looking through a gray filter. The colors are not vibrant.
2) There is no image stabilization. It will record the slightest movements of your hand or vibrations of your aircraft, and being HD, it's very noticeable.
3) The outputfile is not compatible with Deshaker, you will need to covert your video to another format first (which is fine, as you will also need to add contrast anyway.)
4) It does not handle low light conditions well.
Ilike the generic mp4 format; primarily because it's not the proprietary Apple mov format. There must be a program for post processing but Idon't know since I don't do any. The shake is noticeable but no different from another FPV camera. I intentionally flew smoothly for the linked video because people were asking about its abilities. At altitude the flight was smooth but around the ground the wind was gusting. I've posted other videos from the Webbie on Vimeo.
Its image quality can't compete with a standard camcorder but I'm hooked on using it for FPV.
