We asked - you delivered! Thanks a lot! You’re the Goat of Resolve tutorials!
I'm gonna have to take one of those Fusion courses, I get so lost the moment all those nodes pop up...
Tip: Spread your green screen/cyc out. Take a water bottle sprayer with a fine warm water mist and spray the background. Let it dry and you should have removed 90% of the wrinkles. If you are a still shooter (like me) it also works with photo canvas' if you have tension differential (spray the back/non image side).
I have to update this: For polyester backdrops with deep creases you will need to steam or iron them flat. Lighter wrinkles should not be a problem but you need to spread it out with light tension.
Excellent advice, thanks Casey.
I was on crossroads 6 months ago whether to learn Nuke or Fusion. Well, Nuke is great but I just did not have the money for the damm thing. But then discovered your channel. I have learnt so much from it I can't even begin to describe. Today my work pipeline from shoots and Blender is so sorted that I don't even think about Nuke. Please keep these amazing videos coming.
You make excellent content. That's the stuff
My two woes are Light hair and green leaking into the hair colour and green reflections on shiny objects say a guitar as an example
Truly, the 2nd best thing you can do is light the screen as evenly as possible, the first thing is to light your subject to minimize spill on to the talent, and it can come from the most unexpected directions... like overhead, for months I was fighting this until I popped a light above the talent straight up to the white ceiling that was catching hair strands and driving me crazy, trying to get that under control. Once done, even a pretty poor wrinkled and messy green screen can be made to work. My challenge is that I don't do talking head or half body shots, but full body and need to get everything from head to toe clean... that is the real challenge!
Thanks Casey... how about a video about the Mat Control object!
You did it! ♡
I am having difficulties to understand which node is which node type. What is "Combine_MC"?
I would love to see how you manage a green screen with very frizzy fine, blond hair,or other thin and moving elements. I had done my best with getting a clean green background, but admit it could have been better. I managed to do ok on most of it, but the big blonde frizzy wig was near impossible for me to get right. Thanks for all the great advice
I haven't committed to buying, but does the magic mask feature do as good?
Casey, I have set up my green screen (actually blue). It's evenly lit. I used the delta keyer to create the alpha channel. I have my one actor. He's cut out wonderfully. He looks great, EXCEPT I can still see though him, he's not completely opaque. Ugh! I don't know what adjustments to use so that I can't see through him. Your expertise, please. Thanks! Simon
Will creating a "clean plated delta keyer" do the trick?
Please create a part 2 of this video.
Great video - Trying to decide if I need the basic or advanced course? I've used AE and I've done a lot of (successful) keying in Fusion via trial and error, just guessing what many of the tools do. So, basic or advanced? And a woe... Getting rid of motion tracking points that were placed on the green screen. Woe is me...
Probably could go advanced.. but make sure you know how nodes work first.
Why when shoot with the Linux s5 the green screen footage comes out black when keyed out 😢
Pretty much every green screen I had to work on was shot with the "Durrrrrrrr let's fix it post durrrrrrr" technique
I did somehting crazy the other day.
My 12 year old daughter needed to shoot a video for school about a natural disaster. She decided to do it as a fake newscast. I wasn;t prepared for that (daddy my friend is coming over in 30 minutes shoot our video) so I didn;t have all my lights available. What I did to light the green screen is a placed it IN FRONT OF MY PATIO DOOR and BACKLIT it.
I added a shower curtain over the patio window to diffuse the light a bit.
It wasn't perfect but it worked better than expected. LOL.
I've seen some guidance about how you should always shoot at a higher frame rate against a green screen. Like if you plan to deliver at 24 FPS, you should shoot your green screen footage at 60 or even 100 FPS if you can so that you get really smooth motion if there's hand waving etc. Can you speak to that at all?
You're correct that motion blur can make the footage harder to key, but I think the more important part of this is that at higher frame rates you shoot with a higher shutter speed. When I shoot green screen I still deliver 24 fps files, but I shoot with a 1/100 (90°) or 1/200 (45°) shutter.
Maybe someone can help me? I have a felt green screen and two soft lighting stands. I am trying to video products that are about 4' away from the screen. The issue I am running into is reflections. The majority of products I film are reflective. This causes my green screen key to show up in the reflections on the products I am video taping. What can be done to solve this issue?
situation
relatively good light - but still have different problems:
- reflections on spectacles glass although the lights a positioned aside and not frontal but that causes less light direkt to the speaker
- noisy edges
- a lot blur and green between fingers on moving hand
I recorded in HD with 25 fps - maybe I should record in 4k with 50 fps
We are in Germany, Europe - with 50 hertz power frequency
Terima Kasih
I don't have anything to hang my green screen up so I use two sticks and prop it up outside 😭 I need a proper green screen setup badly
I would like to see a moving subject in a moving shot. Like a person who is actually moving with a shot that is moving a the same time, like Game of thrones, Lord of the Ring , etc… ❤pls
noice
My wife has silver hair and the green of the green screen reflects into her hair giving it a slight green tint. She is 4-1/2 feet away ("studio" size limitations prevent much more distance). How can I deal with this? (funny, I don't seem to have a noticeable problem with my chrome dome).
Have you tried blue? One color is better for certain situations and I believe blue is less reflective.
@@HikingWithCooper No I haven't tried blue. I do not have blue. I might see if I can procure one. I wear a LOT of blue so I'd have to swap the blue out when I shoot my videos ... or not wear blue! I shall consider this. Thanks.
A light pointing down (hair light or down light) can help.
Have you tried the despill capabilities of the Delta Keyer already? That can help a bit.
@@stephajn I cannot say that I have. It is worth a try. Thanks for the advise.
1:27 how we do green screen
Lighting and big distance between subject and screen! The rule is at least 6 feet away to eliminate shadows
Completely off topic question. I bought my BMPCC4K on November 2019 and of course received a licensed copy of Resolve. Tried to use it yesterday, loading screen came up, asking for security key. I entered it, and it told me it was the incorrect key. Any idea how I contact Blackmagic to resolve (haha) this issue? Thanks for all the amazing content you provide!
We use green wall xD, is just much cheaper to paint the wall with green .
What a bit of a coincidence... I just keyed the BEST green screen ever, near perfect and it was done in Fusion... where were you a week ago... lol. I'll have to watch the video and post my thoughts right after... thanks Casey, I am a bit of a long time watcher, now subscribed... love your channel.
Me watching this video after shooting a horrible green screen video
Better yet, just use magic mask :P Unless your a pro or something just go to a fabric store and have them cut you whatever desired green fabric you want.. its a few dollars.
Incredible, believing that everything you'll ever wish to chroma key will be something in front of a bloody green screen. Jesus.
I pretty much stay till the end of the video not because your videos are insightful and I just may learn something, you never know, but because of what HILARIOUSLY random thing you do or say............................. SHUT UP MOM I'M WATCHING A VIDEO HERE!
Pretty useless tutorial ngl
