Bad boy film maker from Tucson, AZ.
I like travel documentaries the best. Like Point and Shoot is a really cool one, Restrepo is alright, Between Home was pretty awesome, stuff like that. I think capturing a real moment or adventure can make for a very thrilling viewing experience.
When I have a small space and not much room for lighting I sometimes like to just take a 1k or 2 500s and point them at the ceiling, this gives everything a soft lighting with few shadows. I like to put a couple practicals in the shot and try to aim the lights near a practical to make it seem like it is generating more light than it actually is, plus practical lights can make shots look really nice.
You can edit on it for sure. I edit on a really old amd a6 processor with no graphics card and 4 gigs of ram on my secondary station and yeah it's slow but it works. I edit 4k footage on it too, pre-rendering gets a little old, and the exporting time on my bad computer is really long but it's still helpful to have. Depends on how much money ya got really and how urgently you need it. 12 gigs should be fine can always upgrade video card if you need as well.
My recommendation though would be to keep using the one that isn't yours until black friday or cyber monday deals in november and buy a new system for cheap. Might be able to get a little more bang for your buck that way since it's only a couple months away.
Id go with something like http://www.bhphotovideo.com/c/product/285925-REG/Lowel_DV_901LBZ_DV_Crea... there are more kits with different lights depending what kind of setup you are looking for but this is a fairly cheap setup to get things going that can be supplemented as you find your needs increase. Not as portable though but if you are doing showreels and narratives there should somewhere to plug in within the reach on an extension cord.
Another thing worth considering is non tungsten lights can often give a non-continous spectral output that can effect the appearance of color. Take note of how the bottom images light isn't continuous, granted that is fluorescent bulb but I believe the principle still applies. https://upload.wikimedia.org/wikipedia/commons/1/1a/Simple_spectroscope.jpg
I think the best thing about this kind of setup is they are durable compared to the led lights which are made of plastic.
I'd say it depends on how in control of the light you want to be. If you are the type that likes complete control of the light in your image I'd say go for more power and get some gels. Also depends on the camera you are using if it is a dslr more light is always better.
Couldnt see the video cuz its blocked in my country but if you are referring to the shot the begins with a rack focus on the night fox that zooms out it appears to be a telephoto lens being zoomed out while being dollyd backwards that tilts up at the end. If this isnt the shot let me know which one you were talking about.
