Everyone else has already advised you that a dSLR is designed for still image capture and to get a camcorder for video capture. I agree. But what the others have not said is why - other than "primary design features".
Pick a dSLR you *think* you might get - but don't buy it. Go to the manufacturer's website, locate, download and read the camera's manual. Things you will find:
1) 90% or more of the manual is dedicated to using the dSLR for capturing still images. While not published, the implication is video is a "convenience feature".
2) Since video is important to you, be sure to find and read the (short) chapter on capturing video. Specifically, the file segmentation (single file limited to 4 gig which varies in duration based on the resolution and compression selected), the limited resolution and compression options available, the warning about the internal mic picking up camera noise when auto focus and aperture is used (use an external mic - preferably in a shock mount) unless the dSLR has no mic connection... so be sure you have budget for an audio field recorder... and the warning on overheating and auto shut-down until the camera is cool enough to resume use and low battery life when capturing video. There are others, but these are the biggest hassles for which you need workarounds - that you do not need with camcorders.
None of this means a dSLR can't capture good video - they can, but under very specific instances, including great lighting. One of the reasons many want to use a dSLR for video is because of the interchangeable lens system making it easier to get great depth of field (foreground subject in focus while background blurred or the other way around - and being able to rack the focus).
If the above is the case, then be aware that camcorders can do that, too - when manual controls are used. DoF is easy enough to do under good lighting and adjusting aperture and shutter speed... without the problems of battery life, limited resolution/compression options and potential overheating.
"But dSLRs look more "pro""... Not for video, unless you get a dSLR designed for video capture. The Canon EOS Cinema series (C100, C200, C300, etc.) and Canon XC series use a dSLR-sized single-sensor chip and have an interchangeable lens system. I used to use a Sony NEX-EA50UH. Blackmagic design makes a couple of good cinema cams, too. Yes, these cost more than an entry-level dSLR - but to design/develop a device to capture video as its primary design is not easy or inexpensive to do.
Some friends wanted to get into "film making" inexpensively - and went the low-end dSLR route. They ended up spending more money on 3 cameras (use one while the others are cooling), lots of lighting (learn to use "day for night" video capture and editing techniques - check YouTube) and basically spent more on their stuff than I did on my single EA50UH (which they wanted to borrow - a lot).
You would not get a Prius to haul dirt... you'd want a pick-up truck. Use the right tool for the job...
