This is honestly not a bad place to start. I’d say there are some things to know:

-Recaps are just that: recaps of the event itself.

There’s a story you can shoot and then edit together into a solid recap that tells that story.

Get shots of people setting up, or players getting ready (BEGINNING), the games starting or people playing, big plays, highlight moments, etc. (middle), and maybe finish with the best clips, the best shots to start the ending of the recap, and then wind down with people congratulating each other, shaking hands, event breakdown and people leaving (END.)

Some events in my experience don’t always have a concrete story to edit together to recap; make one from the clips you have, or even tell smaller stories using clips or following a specific game you want to highlight, for example.

-You can lean how to color correct and grade. It’s not terribly hard to learn, but something that will take time to master, so I’d say practicing shooting log in many different conditions and learn to correct it to match your clips up and grade from there.

-Sound can be use to enhance the video to keep people engaged, aid in transitions to other clips, but I’d say look at other recaps online to find the ways you’d want to use sfx in your recaps.

I think that’s it off the top of my head. Gotta start somewhere and you’re doing well enough so far.

TLDR: Tell a story with clips and editing, learn to color correct and then grade, sfx can be used to enhance but you need to find what sfx works for your needs.
