I hope you like it ;)
Firstly, the export quality of the video was great, so you did a great job on that!
Now here are a few suggestions:
- Consider capturing an event on Minecraft that is Unique, maybe full of action (pvp montages), or attach a funny/adventurous/action packed story to your videos.
- When doing speedups of build montages, do ensure that you cover as many open viewed shots of the structure, and consider making a structure which otherwise is Unique, Detailed and/or Appealing, which is what helps your audience keep fascinated when watching.
- Insert some third party video software effects which can help bring the light to a montage, keep it constantly changing, keep your audience interested.
Be sure to also play around with many kinds of styles, from building, to pvp, machinemas, major events (Tournaments, Ceromonies etc.), I'll look forward to seeing more of your videos if you decide to showcase them in the future! :)
