Mike and I have been colour grading the Stand in Line music video. After doing a primary grade to let the black and white levels right, then we moved on to the secondary grading.
Here’s Mike isolating the background. Actually the grey background was very difficult to separate. I wanted to matte out the floor as it had got dirtier through the 10 hours of filming, so the footprints are visible.
The yellow shirts really punched out well. So here we have 3 mattes : skin tones, yellow shirts and grey background
Here’s another shot where we we needed to isolate the grass, to make it consistent. When we were filming, one of the pitch floodlights was faulty, so one corner of the pitch was a strong yellow. My film lights were illuminating the middle area and the back floodlights were blueish
Adjusting the grass colour
The footballer shirts were orange. so here’s the orange roughly isolated
The original colour
..with the orange brighter
..now yellow!
Could even go blue, I suppose, but notice how parts of the faces are changing as the orange floodlight makes the side of the faces orange as well. So it was tricky to separate the colours.
This is making the ball whiter.
Then similar clips are linked.
Very fiddly process
So we can apply the basic secondary grades to a set at a time, before going on to dealing with the individual clips
