Suggestions & Critiques for my lighting (vids)

This is a video of what's inspired us and what kind of lighting/feel/mood we're trying to mimic.

This is our footage. We had a 1k mickey with blue gel over it bouncing off of the ceiling. The other light source was the sun from the window on the left of the subject. It was cloudy and raining that day around 5pm.

Couple things:

1) I was shooting at f/4.0 iso 400. Why does it look noisy? Is it because of the blacks? Also why do some areas look pixelated? (is it artifacts?) for e.g. at 0:51 top left corner.

2) I know I need a hair light, and some fill on the left of the subject.

3) We are shooting in an abandoned building. There is no power so we have to run ac from a building next door. There are 2 outlets on separate circuits available from that building so I don't have that much power available (not sure how many amps but we placed 1k in each outlet and it was fine.) We also have a 1200w generator if we need it.

4) In terms of matching the overall colour temperature, some suggested to cto the windows so I wouldn't have to gel the tungsten lights. What are the advantages/disadvantages in going this route compared to placing ctb on the tungsten lights?

5) We're limited to tungsten lights.

6) I emailed the dp from the vimeo video and he said he had a 2.5hmi from outside, 120 4 bank kino flo (is that 120wattsx4?) as toplight, and rosco panel light on the side of the subjects

We are planning on doing another test shoot this saturday with additional lights so any feedback, suggestions, advice, etc is appreciated.
 
You don't have enough light. That's why there's noise/grain.

Remember: "Dark" in film looks much different before color grading. Almost like day.
 
Simply put ...u dont have enough light. you are basically using a 250w light if thats a full CTB. I hate gelling to daylight. Basically using a full CTB cuts your output 4 times. So yah. not enough light...therefore noise and blockyness. Also iso 320 is cleaner than 400. If you dont know by now the clean ISO's on these canons are 160, 320, 640, 1250. These iso are cleaner than the ISO's below them. SO you solution is add more ...alot more light, preverably daylight balanced lights. (kinos and hmi's for either edge or ambient light by bouncing it)

edit: just saw you are limited to tungsten lights. Yah...CTO the windows. As i said..gelling to daylight cuts your tungsten considerably. Also get devices to make your tungsten lights as soft as possible...Large diffusion screens...Large white bounce board, and get some flags to control it.

Ok, so I guess it would be better to gel the windows cto and leave the tungsten lights ungelled? And thanks for the lesson on the iso's I never knew that. I will try 640 and 1250 next time.

I don't have access to kinos because upper years have priority.
 
well Ideally you dont wanna have to go up to 1250. I dont shoot over 640 usually. Its a better Idea to add more light. however the fact is we dont always have that option.

Thanks. What are some good ratios to follow? E.g. how many stops lower should the background be compared to the subject?
 
To minimize the noise, I would try shooting at an F2.8 or even f2.0 with ISO at 320.

If you really want to be at F4 then certainly add more light.
