Question / Help Can't import videos from OBS to Camtasia

[Lirkeyy]

Hello all. I am very new to both OBS and Camtasia. I thought it would be fun recording my OSU replays and uploading it on YouTube. It's impossible with camtasia because it won't let me import it.. Here is a screenshot:

I am really new so I don't know what it is asking for. Please help!
