This is such a super cool topic! Your video is in your hands, creativity is limitless with video editing tools. You could be superheroes, travel to "egypt," create a murder mystery, or simply record yourself wrecking noobz on Fortnite.
Create an idea
Again, it is limitless! When you think of one idea, you'll think of 20 other related videos you want to make. Write them all down! You can make this idea a hobby! Something to do frequently! Long term hobbies are the best!
Your ideas can be multi-categorized too! You could make a comedy and then a serious, don't be stuck to one idea! Maybe after awhile you grow to like this and want to make some money from these videos! At that point you can begin strategizing what content to post and where, but for now just have fun thinking of ideas and making them!
Record the video
You can absolutely create a BOMB video simply from your iPhone. As you create more and more videos you'll learn where to position each people in the frame and how to have different angles and why angles matter, but creating videos for fun you can just have ONE clip and still have fun! Get a tripod, or simply set your phone on the nearest rock and click record!
Edit the video
This is my favorite part! By being good at editing you can really make amazing videos! If you can learn to add superhero effects, or change the tone of a video by applying the right filters and adding the right music, you can seriously make some awesome videos people would love to watch! But at the beginning, you can absolutely skip this and just have fun recording. The point is to have fun!
Share the video
Maybe at first you want to keep these to yourself (or not!) but as you get better and better, share these! People could absolutely love what you do and this could be a money making hobby you have on your hands! What is better than a hobby that earns you money!?
Overall
This is a super fun activity that allows you to be creative and in control. This can absolutely become a long term hobby, which beats any one short term forms of entertainment, like laser tag for example. This is something you can continuously improve upon and even eventually make money! Fantastic activity for all ages!
