I always render my animations as image sequences and put them together in video editor. I've been using HitFilm for editing and compositing for the last 3 years, currently on HitFilm Pro 2017, lots of effects including particle simulation, lighting, atmospherics and colour correction tools plus Moccha motion tracking built in. It can handle 3D models too. Works great as still image editor too (https://www.renderosity.com/mod/gallery/deploy-under-fire/2740473/?p) There's a fully functional free version too, HitFilm Express 4, though it lacks some of the features but offers them as add on packs
