I am a video production teacher. Is Adobe After Effects all I need?
What exactly are your requirements.
For video, best options would be Premiere Pro & After Effects.
Let us know, if you need more information.
hehe....Is After Effects all you need? For what?
After Effects is for creating shots that contain visua effects or motion graphics. You can create short sequences that you cannot edit anything longer than a few seconds in AE. If you want to edit you need a nonlinear editor like Premiere Pro.
You need to analyze your curriculum and figure out what tools will best serve your students. Editing and visual effects look easy but take years to master.
If your question is specific about video production software, Adobe has apps for all the stages in the video production workflow. You can use Adobe Story for your scripts, Prelude for video logging and rough cuts, Premiere Pro for editing the footage and doing color correction, audio, After Effects for motion graphics and visual effects, Audition for specialized audio mixing and editing, and Media Encoder for exporting your media to the screen size and resolution of your choice. You can start your learning process with the trial versions of these products.
Hope this helps.
