What @UncleVanya said is absolutely right. Also have another read of what @Alex645 said in post #68. In fact I'd suggest you have a re-read through the whole thread.
The suggestions that have been shot down have mostly been for options outside your budget, or didn't meet your other criteria (such as 1080 video with 30fps). Although this is a Pentax site, most people are not "fanboys". Many of us have been through camera decision-making with friends and family and we aren't partisan. Many people have experience with cameras of various brands. You'll notice, for example, that there have been various mentions of the fact the Pentax is behind the game for video.
Let's put this another way. Do a search in the relevant category on Gumtree or ebay for interchangeable-lens cameras with a price limit within your budget, and see what turns up. Then ask yourself whether they offer this combination of features:
1. Ability to use a wide range of cheap but high-quality lenses, including wide-aperture lenses for short depth of field and high-quality images. .
2. In-body image stabilization. (Rules out any Canons and Nikons in this price range.) This is invaluable when you can't afford stabilized lenses.
3. Viewfinder (rules out some mirrorless, such as Sony NEX and Pentax K01)
And video, since that is one of your key criteria.
If they don't have all these qualities, strike them off the list. Now see what's left. There won't be any Nikons, or Canons (no IBIS), or Fujis (too expensive), or Panasonics (Panasonic only introduced IBIS with the Lumix DMC-GX7, which will be outside the price range). What's left? Pentax, Sony and maybe Olympus. Lenses for Olympus are relatively expensive. So that should narrow your choice.
