Https://brush.ninja/ is fast/nice if you just want to do quick stick figure type animated gifs. Start by drawing something simple in the current frame, then down at the bottom, use the "duplicate" to make the next frame and add some changes. - Source: Hacker News / about 2 years ago

I can suggest brush.ninja for online (2D) animations or OpenToonz/FlipaClip for downloadable software animations, along with Blender for 3D animations (all of these are free to download and use). Source: over 2 years ago

I use Stroyboarder by wonderunit (its free) https://wonderunit.com/storyboarder/ You can either draw in the app or make your scenes in another program and drop them in. Eg, I could make a bunch of frames in illustrator on separate artboards and drop them in. It also links up to photoshop with the press of a button. Source: 12 months ago

Or for a more budget friendly option, take a look at Storyboarder by Wonder Unit This piece of software is nice, because it can work well with PSD's so you can use the tools in PS or CSP that you are comfortable with. Source: over 1 year ago

Storyboarder, Blender for Storyboarding, any drawing software with animation features or software licenses distributed by your university, should provide you enough options to fulfill your tasks. Source: over 1 year ago
