Particularly intensive is the process of rendering your finished product into a standard video file that will by playable on the target device of choice, be that an HDTV, a laptop, or a smartphone. Most of the software can take advantage of your computer's graphics processor to speed this up. Be sure to check the performance section in each review linked here to see how speedy or slow the application is. In rendering speed testing, CyberLink and Pinnacle have been my perennial champs.
Video editing is one of the most computing-intensive activities around, so you'll want the best laptop or desktop you can afford if you're serious about cutting your own movies. Most applications help speed up the editing process by creating a proxy file of lower resolution, so that normal editing and previewing aren't slowed down by the huge full-resolution files.
You might also be looking at the older T6i. I reviewed this camera a lot last year and it was a great beginners dslr. It doesn't that dual pixel autofocus, instead it has a hybrid autofocus. Personally id recommend getting the t7i instead. On the upper end you could look at the Canon 70D or 80D. I actually use a Canon 70d and love it, and the 80d is a step up again. For beginners to intermediates, the t7i will be more than capable, but if you really want a great camera, go for the 80d.
Those looking for a powerful editor with a huge variety of built-in resources and responsive technical support may be better off dropping some cash on a consumer video-editing program, like award winners Adobe Premiere Elements, CyberLink PowerDirector or Corel VideoStudio. However, first consider trying out software such as HitFilm Express 2017, VideoPad, DaVinci Resolve or VSDC, which offer all of the basics for free, and then purchasing additional features à la carte or simply upgrade as your experience and needs grow.
