Paid professional video, and like all of you guys, I'm a one man team.Ok, so a lot of this is fairly basic editing. 90% of that finished product is dependent on how well they shot their footage. They are doing fairly simple cut edits, their video isnt choppy because they shot it smoothly.
We don't want the final video to be choppy or the voice like too close or too far from someone's mouth.
Glidecam is a must???!Yes on external mic (Rode makes a good $100ish one), Glidecam will depend on your shooting style. Something to stabilize off your shoulder is probably worth it. Also looks like they do a decent amount of tripod based shooting.

I got a 6D and will have 70D soon. I may set 70D, due to easy control via touch screen.
I am looking for a Lens: 24mm equivalent, got IS, and good at still at the same time. Couldn't find at the moment. and Less barrel distortion at 24mm.
As for your lenses, IS will be required. I wouldnt consider any lens that doesnt have it, as that is a run-and-gun style of shooting, and you dont want to spend time stabilizing in post.
Lots of IS lens options from Canon (24, 28, 35, etc), and there are 3rd party options that would be good as well. Something like the new 16-35L IS would be a good lens for both cameras; it'd be a good walk-around lens on the 70D for that style of shooting, and a nice wide angle for your 6D. Combo'd with a prime or two for closeups and you'd be off to a good start.
