We are all at best guessing, but my guess is that if the price falls on black magic cameras that only ones that have lots of batteries and extras will sell since no one will want to put money into them, then there is lots of competition that may well marginalize them as well.
I have a Canon HV20 that I paid about a grand for, it was the darling of indie filmmakers a few years back, it had its own website and tremendous interest in it. Anyone these days can buy a used one for $100. I am still amazed how terrific it can look and there are some wonderful films that were made with it like https://vimeo.com/9080438 but who wants to use tape anymore? then Cineform doesn't make the pulldown software anymore so all you get is 60p instead of doing pulldown and getting 24p out of the 60p stream. Yet they maintained value for a long time, a very desirable camera, but nowdays most people will not take it even for free. I suspect the BM cameras will be the same way. It is just likely we can better cameras for less money that look better and don't eat batteries etc. So that is my prediction.
I am surprised that these cameras have not been recommended yet. First of all I am not a camera snob and I think that used well my recommended cameras are capable of stunning video when used well. They are all Canon, but for one reason, Magic Lantern which is free software that goes the memory card and turns these dslr into fire breathing movie machines. Namely the T2i and the T3i, the difference being that the T3i gives you a swivel lcd screen. Also the Canon Eos-m all of them available used for under $200. All of them have youtube tutorials that teach you how to optimize settings for great video. I still use mine all the time and have not "upgraded" since they look terrific when used well. The problems that some people have with them is more due to them not learning how to use them properly. As far as lenses go, one lens seldom talked about but available for $200 used is the Canon 17mm-85mm. They sold new for about $600, but are a steal used and of course the Canon nifty fifty 50mm 1.8 is available for under $100. I have mine, but I bought them new, I have a T2i, T3i and 2-Eos-m check out this video https://www.youtube.com/watch?v=Gb58PSxuj8s and https://www.youtube.com/watch?v=HE-VWdZUM1w here is a tutorial for using the T3i for video costs under $39 http://www.learningvideo.com/store/t3i_sales.php You can compete with most people posting here with these recommended cameras, the key is your knowledge and ability to use any camera. In your budget you can have a terrific movie making set up. The suggested videos apply to any camera purchase. Magic Lantern homepage http://www.magiclantern.fm there are many videos on youtube on what magic lantern does and how to install it. http://www.magiclantern.fm On amazon https://www.amazon.com/gp/offer-listing/B0002Y5WXO/ref=dp_olp_all_mbc?ie... I would avoid the ones under $100 by people that have no feedback, likely is a scam, but all kinds of people with feedback selling for little more than $100 for this zoom lens
personally I would blur in post with your nle, that way it can be as sharp or blurred as you like. Sure you can use filters, but then you are locked into that image.
The good is the former sony vegas is now magix Vegas 14, I use sony vegas 13 and altho i had 10 back in the day, Vegas has always had every output option known to man and beast, so like Stephen said use what ever the requirements for the festival and no doubt you have that ability already from the render menu.
Well if you look at world wide use, PC has aprox a 94% market share world wide, Mac has 3% these can change a little, but has been this way for years. Mac software doesn't even have a 1% penetration world wide more like 1 in a thousand. The world has spoken. So, it is possible that in your workplace that they use Macs, but it is rare.
