Always glad to see someone giving video a go. Good stuff.
Love the start, nice framing, depth of field choice etc.
That wide angle shot would likely benefit from some light warp stabiliser.
Using Warp Stabilizer in Premiere Pro CS6 | CS6 & Creative Cloud Feature Tour for Video | Adobe TV
My favourite field of view for this is the 35mm and the plastic f2.4 works great for me, and I can see why the 50mm 'standard lens' on FF was so popular.
The 50mm is likely to be similar, but you'll be standing further back, out of the smoke in your case :-)
Personally I'd look to turn off the stabilisation in the camera, as I don't feel it works very well, and with Premiere you can get a bit more flexibility over how you stabilise in post afterwards.
It's very slow to apply afterwards though, so it's always best to think about camera shake at the time you are shooting, and try to get that as stable as possible then.
Now just let you imagination run wild, and think of different shooting angles, telling a story etc.
Very similar to say how you would layout a wedding or event photo album, only with clips from the event to tell the story.
Thanks for sharing!
