Open Source Adobe After Effects Alternatives
Arguably one of the best video effects editors in the business, Adobe After Effects provides users with a robust suite of tools and documentation to enable both novice and professional video editors to do what they need to in order to create stunning visual effects for video and film.
Alternatives with a similar workflow include 
FXhome HitFilm (which has a free option available), Blackmagic Design Fusion, and NUKE.
For more especially purposed programs that are concentrated on 3D modeling, screen capturing and recording, and advanced motion tracking instead of post-processing and video effect editing, you've come to the right place!

Natron vs Adobe After Effects
fahadhasanpathik A Node based approach for not only vector and raster image processing and animation but also for OpenGL effects and shader authoring. Also supports OFX. Mainly targeted for VFX compositing.Its simple (when you get the arrangement) but still very powerful, easily works with Blender and its free!!Awful documentation (blank page); The versions change so much that the old tutorials don't help at all; Difficult to learn by just messing around; High learning curve.gauthierhaas00 Bad support for zoom-in on SVG and fontsNatron can import SVG image and edit node. However, Natron cannot export SVG file.POX Free and open-source node based alternative to After Effects. It's pretty similar to Nuke, but doesn't cost anything.Rotchka22 Its hard to understand at first, but once you know what you're doing, every things is worth it - Blender is the free and open-source 3D creation suite.

Blender vs Adobe After Effects
Yeah, you can edit videos with it... But it's not made for it in specific and isn't it's main purpose. It has lots of purposes.It clearly doesn't look like after effects and has a pretty steep learning curve, but it can do anything that after effects can do.danielmichel AE's main purpose: Video effect editing. Blender has a whole range of possibilities, but it's hard to get into and it's not designed to be used solely for video effect editing.Blender is a 3D suite and the node based compositing workflow differs a lot from after effects.It is free and u can use it for everything. You can Design you own thingssas_ja Blender is has a bit different workflow, that doesn't make it worse than AE. People think that Blender is only a 3D program, but it fact it has greasepencil (2d animation tool), and it also includes node-based compositing, video editing and video tracking. With Blender you can combine 2d animations, 3d renderings and video footage without using any external program.Blender is a very powerful tool, don't get me wrong, but Blender is not focused on video effects. Blender is more focused on 3d modeling and animation. Blender can do what After Effects can do, but only to a certain extent. - Snowmix is a video mixer tool for mixing live and recorded video and audio feeds.
