See what instructors are using to edit videos!
My workflow is based aroud Adobe apps. Premiere Pro is a main "work horse", I also use a bit of AfterEffects, when I need infographics (to be honest, I don't do that too often). I record videos in Camtasia, but I don't edit there, it is way simpler to organize big project in Premiere Pro.
Personally, I use Final Cut Pro X (Mac only). It is an industry standard along with Adobe Premiere. It provides me with the video editing, audio editing, acts as file organizer. One thing I love is that it lets me save presets from previous videos (such as how much crop, where the video is positioned, color corrections, etc) so I can apply them to future videos. That's been great to save a lot of time once I setup my studio correctly.
It also has a great green screen option, it allows for outside plugins (such as on-screen graphics and animations), and the multi-camera option has allowed me to save a TON of time when editing. It's a bit of an investment at $299 and I know there are lots of other options for free out there too.
I use Adobe Premier Pro and love it. With that I also use Audition to clean up our sound. I tried Final Cut, and while it has amazing tools, Premier just clicks in my head. I am working on an iMac Pro if that helps too. I used iMovie back in the day but one of the version updates they did took away all the features I liked and used and I got mad at it and have barely touched it since.
Screenflow for Mac has been amazing! I do have the Adobe Creative Cloud subscription, so technically, I can start to explore Adobe premiere and Adobe after effects, but for teaching courses screenflow keeps it nice and simple with some pretty decent transition effects.
I use Adobe premier pro. Mine is just slides and voice over. Only takes couple of days to edit. So, usually when I finish editing, I unsubscribe the service. Adobe is so generous that they do refund if service period is less than 2 weeks.
I also use ScreenFlow on my Mac. I have been using it for many years now and it has grown from an application to just record and edit screencasts to something more capable. So nowaydays I even use it to edit talking head videos etc.
I am sure that pro-level applications like Premiere or Final Cut Pro X have a lot more bells and whistles. And I might look into that in the future. But for now I am pretty happy with it.
