Posting videos on Google+ was recently enhanced so the result would be a higher quality video. You know how uploading mobile videos can be done quickly on the social network but they don't always come out nice as the original. Quality would be lower than usual but the Google+ team, as announced by Software Engineer in a post, added some features. The uploader can now edit the color, lighting, stability, and speech in videos. Most of the enhancements are already available but the stability function is coming soon.
