Recently picked up a GoPro Hero4 Black and have been messing around with all the features. I recently went out to try the video time lapse feature. This is similar to taking a normal time lapse sequence but it takes all the photos and automatically puts them together into a 4K video.
What I found was while the video time lapse works pretty well for typical time lapse footage but it doesn't do great for sunsets with the camera automatically compensating for the light changing from bright to dark. Im going to try again but use the regular photo time lapse feature.
Here's the video time lapse I captured.
