We did! The text was created using a specific font downloaded ot our editors computer (Camtasia can recognize system fonts) then we added a behavior to the text to animate it in (the Behaviors tab has a bunch to choose from).
Hard question to answer. They're very different. Canva works a lot in pre-built templates. I've not done screen recording with them before (hi, it's Andy!), but it may be possible. With Camtasia, everything is customizable and flexible as well. You can record your webcam and screen recording and edit them with greater flexibility in my opinion. But, Canva definitely wins on the sheer volume of templates they have. That's where they intentionally excel.
