Lots of us record videos. Many videos that sometimes don't seem so good as we wanted. There are many reasons why this happens, but in my opinion, the phase should not be forgotten it's to check the colors of the video (and it's maybe the most important part).
When I record videos with my GoPro, the longest phase is not recording but the post-production. For a video of 3 minutes I take around two days (or more) to unify the videos, check the color correction and export. Of course the editing and the creation of a video takes much more time, because you don't simply need to record, you first need to think what you want to record, what you want to show. This is maybe the longest part of making a good video, because you've to record scenes that you'll need to compose the final product (as the scenes of transition).
Well, however, do not digress, here I would just like to emphasize the importance of a step often overlooked: the color correction. If you want your videos to look gorgeous, never skip this phase.
