For the technical breakdown and settings, skip to the end.
In the early years of my 20 years behind a camera, I saw so many filmmakers–as soon as they picked up a camera–want to make videos with a green screen.
It was bad. Like, really bad. …So I took a vow to never use a green screen until I could make it work.
I kept that vow for nearly two decades. Until Teacher of the Year 2023.
These are people sharing why their life’s work matters to them. I have to meet them in these tearful conversations or risk missing their story. Every year, I secretly called it a 6-way tie.
On-site, it is a complete rearranging of their classrooms into an interview “set.” The sound environment is a total wildcard. Bells ring, phones ring, A/Cs roar, kids roar. Then I immediately tear it down for the B-Roll recording.
But then I got an upgrade. Blackmagic 6K, 50mm Anamorphic lens, totally mobile lighting rig with the Aputure light & dome on V-mount batteries, Ronin Pro, and Atomos Monitor. It’s a B-roll machine. And let’s not forget… a green screen for the A. Granted, this is just industry-standard stuff, but it was a leap from using personal equipment.
For the first time, it was possible for them to come to me for interviews. HR booked them for me with no back-and-forth emails or calendaring.
Oh, it was a dream come true.
Except for the green screen. I was nervous. The day had finally come when using one was more practical than on-site A-Roll recording. But this is my first time. It has to be perfect. No green halos, no green bleed, no hazy outlines.
You might think, “Luke, this is seriously overkill.” Honestly, I’d fake the moon landing on the moon if it made it feel more real. It really feels like a sacrifice of identity to just “let it slide this time,” when I know I can do better. …See the results for yourself.
Lesson 1: Document Everything
Light intensity, height of the light, distance from the talent, angle of offset from the focal point, camera settings, all of it. If I couldn’t duplicate the setup later, I had no chance.
Show time.
They’re uncomfortable walking in, no matter if I filmed their classrooms or not. But this time, I’m cool, not sweating, on my home turf. I can do my hospitality things, cold bottles of water (branded), tissues, and small talk questions prepped because I’ve had my green screen set ready to go for weeks now in a perfectly controlled sound environment.
I bring out the power questions.
- “Who do you personally know that inspires you?”
- “What keeps you going when it feels like too much?”
- “How are you providing for these kids what you wished you’d gotten in school?”
Gets ’em every time.
Six interviews, back to back. What used to take a week and a half was done in half a day. I schedule their B-roll recording before they leave the room.
But we’re getting down to the wire here. HR couldn’t book all six teachers in that first week, just at the end of the second. So I do as much prep work as I can, and of course, half-day photoshoots pop up with editing needs. Now I have two weeks to go, including editing the video.
Unfazed, I stuff my Honda Civic with the set and go to each campus. I’m welcomed in like an old friend. I just need an hour to record the B, about twenty minutes to duplicate my green screen setup, and the emotional toll is nil.
Lesson 2: Duplicate Your Setup Exactly, Record an Empty Room
I recorded a minute of just “empty room,” and that was the best move. In the edit, I dropped in a static image of the room, and the grain and noise were at a standstill. It looked too “photographed.” So I looped the minute of empty room, and it came to life.
Still a lot of work filming it, to be sure. Pulling together a cohesive, coherent narrative out of 3-5 hours of off-the-cuff interview content that isn’t repetitive or a ramble of slogans takes real time. 40-60 hours easily, before transcripts and AI sped things up.
But the real surprise wasn’t the edit.
Turns out, when used well, green screens are a tool for protecting people’s energy and telling their stories better.
Looking back, that vow was about not wanting anything fake to get in the way of a real story.
And if it helped me do right by the people in front of my camera, then it did its job.
The Unexpected Benefits:
- What used to take a week and a half took half a day.
- The subjects were less drained.
- I was at my best.
- Pristine audio.
- The stories were better
- Camera, tripod, audio gear, etc.
- Green screen
- Key light with diffuser
- Hair light (LED Panel)
- Two LED panels on the green screen
- A few feet of space between talent and green screen
I made a custom background by recording on-site of the background I wanted to replace the screen with. I duplicated the lighting conditions.
I documented everything from the green screen set:
- Light intensity
- Height of the light
- Distance from the focal point
- Angle of offset from the focal point
- If an LED panel is used on a ball head, note the orientation (landscape/portrait)
- Camera settings
- Light the green screen evenly
And matched the lighting conditions at the location of the background image.
- Import raw footage
- Crop out the background to only hold the area in which the subject moves
- Chroma Key the green screen out
- Color correct to balance the colors of the subject
- Drop in the background that was matched on-site
- Loop a video of the on-site recording rather than using a still image
- Color correct to match
- Condense that into a compound clip/nested clip
- Color grade to stylize.
