I have edited over 450 YouTube videos just on my channel alone. There's lots of little or big tasks that go into video editing and usually each task is done by a different person, but I can do them all!

Build a story with the provided clips

Color grade

Adjust audio levels

Fix bad audio - Lots of background noise or chattering? I can remove it!

Cut, Trim and Edit clips

Add Transitions, Text and Effects

Transcribe audio

Add Eye catching Captions or Subtitles

Sync audio

Make custom Motion Graphics and/or Templates

Make Intro & Outro animations

Make the original audio fit the intended scene/mood (ex. as if talking in a tunnel)

Giving your video an (Analogue) Film Look

When it comes to the type of content I can edit? Basically anything, the only thing that I don't do is movie quality video editing & visual effects.
