Green screen editing- keying out and the problems I had

Ok So yesterday I was trying to correct the old building footage, now was the turn of the green screening and keying out the colours.

I had saved the tutorial sheets that I was given on the channel 4 day so I hunted them out, It was great help!

It told me how to do it step by step and I wasn't wasting my time looking for a youtube tutorial.

Here is my first green screen test:

I think it worked really well! I was happy with the results from this test and so I am now starting to put this music video together and I'm hoping to have the first edit done tonight!


Then as the night progresses, I start having REALLLL problems with some other green screen footage. Then dont work as well and the boys still have a haze of green to them, I couldn't figure it out, I even started writing down all the numbers so I could copy them to the other video.. still didn't work.

Here are screenshots of places that the green screen didn't work out so well

Parts of fingers are missing at the sides.

 green haze around daniels back and lewis's hand is not refined enough and green shade under armpit

 green hand and haze around head

 green haze around side, green shadow and unrefined arms

 green shadow all over face

 even thought I believe this to be my most successful green screen, there is still a small hint of green in the shadow

 huge green shadow on face

 I was really annoyed that the old build shots didn't work out so I tried to put daniel in the picture, this worked quite well, I made him the same shade and tones as the background but it is not fully conceivable

 unrefined hand

 slight green haze around the body

Light reflected off the size of Lewis's eyebrow and ear



BUT

Baring in mind these errors only occur for a small part, this is just me trying to pick at my faults. I have realized where I have went wrong:



LIGHTING

I never lit the green screen properly, if I had more lights, it would have removed the shadows off their faces and I would not of had the problems that I did. But I learned from the experience.
