This is useless for 99% of the content creators out there. Only filmmakers/movie studios/or education use would benefit from this. People should realize that most online video content needs to be snack size (2-5 minutes MAX).
Audiences are too fickle to watch more than a few minutes of video. The average video is watched 2 minutes and then people taper off. They would rather consume more pieces of video (quantity) than more of a single video.
In the lean-back environment, this would be a different story.
