It's actually better to put a green solid over the shadows to act as a garbage mat rather than rotoing the subject because if the key doesn't go perfectly you will still have a balanced look. Film Riot -- Can you please do a quick tips on folding the green screen?
I don't comment much, but been watching your channel for awhile now and learned a lot! Making quality cinematic content is a goal I keep working on with almost all my videos. I just wanted to say thank you so much for all the awesome tips and excellent short films!
Really great succinct tutorial on green screen. There are a bunch of them on TH-cam but this is the best to the point, this is what you need to know with examples added too.
Thanks so much for this episode, especially the tip of adding the second duplicate layer info. I had been struggling with the artifacting on my subject for a while. I used your tips and HOO BOY! my keyed footage now looks really good. I can sleep well tonight.
Great episode. One thing you didn't mention when talking about green vs blue screen is that due to the Bayer pattern. The color green is sampled twice as much as red and blue so you have more color information to work with for the green channel.
When I got my flex green screen I could not fold it at all and I was so frustrated, but after a few TH-cam tutorials and about a week of failure I finally got it!
Applying Alpha on the second layer was a MASSIVE workaround. Now KeyLight is definitely USABLE. Thanks a lot for the tip! Love you guys. I'm a Full Sail Alumini(2008) by the way. Film Riot
This channel is amazing. Thank you! In this one video you addressed every single issue we've had while playing with a green screen! :) Our noise was in the hair. Fun effect unless you've already been working for 5 hours on a single scene. He had a proper disco ball hair-do for a while :)
Also if you have noise in your green screen try switching the key light to hard color instead of soft color. That usually works for me and it keeps the key light properties (color spill, edge settings, etc.) in one easy to use place.
I am happy to hear you have a Creative Guerilla Film Making class. That is exactly what I need instead of the local community college film course. My wife bought me a Canon Rebel T3i this past spring so that I can start learning to film. Eventually find a few people that can pass for acting and build from there. This is the best TH-cam channel ever created. When I first saw you guys it was 2010 and since that day forward I consumed film making knowledge. Without your channel I don't know if I would have ever thought it was possible.
At the end my eyes darted back and forth from the video to the playhead, waiting anxiously to see Josh fold that thing like a pro. All I gotta say is PROVE IT! :)
Just an FYI: for getting as tight a green screen as possible I use the "green screener" app from Hollywood Camera Work on my smart phone. It turns my phone into a green screening wizard and uses the live camera input to indicate where the hotspots and and cool spots are. I was able to get the best and most even results I'd ever obtained using this app. Made keying in Vegas a breeze. Highly recommended.
Caught some of the Creative Live - wonderful film-making intensive, certainly has everything one needs to know to get going on their film-making career.
Great video! Coupla extra thoughts, with the disclaimer that I'm by no means a keying expert. However, I do have some experience with set lighting. 1) You said that we should use a shorter shutter speed, but also keep the ISO/ASA low. So we'll need to throw more light on the scene to get the same image (as the rest of our shots) since the camera will be taking in less light. Just something to be aware of when shooting. (Or opening the apeture more to compensate is also an option, but that has other side effects as well, or may not be possible if you were already shooting wide open anyhow.) Also, if you use a light meter, then you should be able to put in the new camera settings and light off the meter. 2) Make sure the green/blue screen is taught. It needs to be perfectly smooth. Even the slightest wrinkle can create small highlights and shadows that will be annoying to deal with in post. (If a wrinkle is far from the subject, you may be able to just garbage matte it out, though, as they showed in the video.) 3) Make sure the subject isn't standing too close to the green/blue screen. Since you're likely using different lights to light the subject and the screen, you don't want the lights for either to spill onto the other. Also, the light can bounce off the green screen onto the subject and create the slightest rim (kind of like a rim light - think of the green screen as a green-colored bounce and this will make sense). Since it's slight, it may not be visible when you're shooting unless you're really looking for it, but you'll see it in post as a fuzzy green rim around the subject. The farther your subject is from the green screen, the less this effect will be. (They don't need to be super far from the screen, really, but you definitely want at least a few feet / a couple meters.)
Love the show. Just a quick tip for you instead of using the Keylight layer as a matte if you just change the view setting in Keylight to intermediate result it will pull the green color and not do the spill corrections. Just a quick way to get the same results. Rock on dudes.
To get great footage when out shooting I use two of my iPhone Apps, Green Screener and Cine Meter. Hope this helps everyone including possibly the Film Riot People! Keep up the Awesome Work
You have "Intermediante Result" on KeyLight.. You don't need to duplicate the layer to make a Alpha matte... Put it in Intermediante Result, and use a Spill Supressor plugin, After Effects CC 2014 already have one, Same result, one layer... ;)

An even easier way to get rid of the noise from the spill supression, is to just change the setting in Keylight under Screen Matte --> Replace Method to Hard light (rather than the default Soft Light). If there's still a bit left you can tint the replace color slightly green.
It's preferred to use a blue screen when keying a night scene. Blue screens were used extensively in Zodiac for action that was predominantly set in the dark. Traditionally films often use a blue cast to simulate moonlight. Therefore a blue screen works with that. Not everyone does this of course, but it is quite common.
Film Riot No one shows how to pull good key for moving hair (female) because with all the strands etc can you cover this? I'm sure resolution is a big factor? If shot 4k, more detailed edging etc
Really appreciate you showing what you use and making a recommendation. I am primarily needing one for streaming(Removing my BG as I feel it takes up too much screen room) and I feel like this might be way over kill on size for my needs. Any recommendations for a smaller fit?
Good video... I need to green screen outside of a 737 cockpit for my next short film. I am concerned about the following: Weather and lighting. It's a full size 737 so I am going to have to get the screen up high. Any tips? Do I have to build a tent around the cockpit or could I simply put the green screen outside the aircraft right against the window? Also will this key out the glass when filming from inside?? Any help would be really really appreciated :) cheers Scott (UK)
You don't need to use a duplicate of the keyed layer as a matte for the unkeyed layer, you just need to set the replace method in the screen matte settings to source, instead of soft matte (or whatever the default setting is). This way, you don't have to create a new comp just for the keyed layer.
This is interesting but I have two questions: Which camera did you use? What recording format did you use? Full HD, 4K, internal recording or to an external capture device? 4:2:0 or 4:2:2?
There's a shortcut to remove the noise without creating an alpha matte layer. You can just go to the Keylight plug-in and switch the view mode to "Intermediate Result."
Hey , I want to go make night shoots in the woods with mountainbikers and freerunners. But I want to know how much light I need ? And how can I get light in dark woods?
hello really thanks for uploading this video!! i have a very hard time with th green screen... i crop my video from left and right, but when i put m video to a backround i see the lines where i did crop the video from left and right, how i can get over it? please help me!
Having trouble with way too much spill after using the technique. I used the choker, spill suppressor, and hue/sat. It got a little better but too much green still in his hair. I traded one problem for another. Any other thoughts?
Thanks for this Ryan, it was extremely useful,... I shoot in PAL, so on my Canon 5DM2 the setting is for 25 FPS - and the Light Frequency for the Tungsten Lights is 50Hz so I have to use a Shutter speed 50. I tried using higher Shutter speeds to avoid the green halo around fingers and fast moving body parts but then I get flicker in the image. Any solutions to rid that green halo other than shutter speed? Or maybe a different type of lighting?
3 Years later and I still reference this video for fixing noise in my key. Thanks Ryan
It's actually better to put a green solid over the shadows to act as a garbage mat rather than rotoing the subject because if the key doesn't go perfectly you will still have a balanced look.
Film Riot -- Can you please do a quick tips on folding the green screen?
FINALLY! I never knew how to get rid of the nasty noise you get when you key your footage. Ryan, you're the best.
Great Green Screen tut from Ryan Connoly and the Film Riot crew! So simple yet so mindblowin.
I don't comment much, but been watching your channel for awhile now and learned a lot! Making quality cinematic content is a goal I keep working on with almost all my videos. I just wanted to say thank you so much for all the awesome tips and excellent short films!
The alpha matte trick was genious!! Can't believe I haven't come up with it myself! Thanks Film Riot!
Really great succinct tutorial on green screen. There are a bunch of them on TH-cam but this is the best to the point, this is what you need to know with examples added too.

That was mentioned right t the beginning when he explained why green is used over the color blue.
Alpha matte... I am kicking myself for not thinking of that. Awesome tips! Thanks Film Riot.
Damn. This was a good video. Informative, polished and entertaining. Subbed.
When I got my flex green screen I could not fold it at all and I was so frustrated, but after a few TH-cam tutorials and about a week of failure I finally got it!
hey i watched your latest video and its cool, you're pretty talented for your age
Working on a project for work, and that Alpha Matte trick was the bees knees! Thanks guys! :)
NICE!!! Just started my first green screen, a few days ago...thanks for your help in moving along!!!
Thanks for this! Never thought about using 2 layers to get rid of the grain. Looks much better now. I'll use this for my next music video.
Applying Alpha on the second layer was a MASSIVE workaround. Now KeyLight is definitely USABLE.
Thanks a lot for the tip! Love you guys. I'm a Full Sail Alumini(2008) by the way. Film Riot
That alpha matte trick blew my mind! Stark's a genius.
do you know how to do it on fcp x?
5 month journey of watching all of your videos and I am proud to say I am finished. keep em coming RyGuy.
the matte technique really blew my mind! it's soooooooooo helpful, awesome!
This channel is amazing. Thank you! In this one video you addressed every single issue we've had while playing with a green screen! :)

Dude! Setting an alpha matte is genius! Will def be using this in the future! Thank you so much!
Oh man, I still have *so much to learn...*
That matte tip for reducing the grain in the keyed out video is just remarkable 😱😱

The best green screen tips tutorial ever !!!!!! thanks guys !!!! You rock !
God, that Matte-Trick is so neat! Simple yet brilliant!
Noise is something I am trying to work out of my videos. Thanks for the video. Now to find your earlier one on noise you mentioned
I can't believe no-one has ever told me/I never figured out that alpha matte technique! That is gold!
Just an FYI: for getting as tight a green screen as possible I use the "green screener" app from Hollywood Camera Work on my smart phone.

That little trick with the alpha matte might just change my life!
Thanks for another one, Ryan! That one help ALOT better than the other one.
My favorite channel to come to for film questions!
this is my lucky day! Film rot replied to my comment on fb! and here i got to know what i was doing wrong! thanks film riot! u r the boss!
Caught some of the Creative Live - wonderful film-making intensive, certainly has everything one needs to know to get going on their film-making career.
The best video i found after wasting a lot of time on random videos. !
Much Thanks!!!
I have never fully understood about track mattes, luminance and all that stuff. So if you make a video on explaining them it
would be really helpful

Do you have an updated video on what are the best LED lights for green screen by chance?
Awesome tips! Thank you!

Just wanted to see if you had some new clever tip, that track matte to Alpha was a good tip.

The TrackMat tip was the best thing evar! thanks a lot guys

Wow, I couldn't their method to work but using Intermediate Result did the trick! Much easier method, THANK YOU!
Great tips!
Why does the spill supressor effect is turned off? i didn't get this part..
thanks a ton Ryan. was in need of green screen tips.
I like to up the saturation of the footage before keying and using that shot as a matte for the same (ungraded) shot.
An even easier way to get rid of the noise from the spill supression, is to just change the setting in Keylight under Screen Matte --> Replace Method to Hard light (rather than the default Soft Light). If there's still a bit left you can tint the replace color slightly green.

Traditionally films often use a blue cast to simulate moonlight. Therefore a blue screen works with that. Not everyone does this of course, but it is quite common.
also blue is good as you work on B/W production as far as I get. I am planing to shot in B/W, is blue a right choice?
Your channel is pretty awesome man. simple and clear explanations. Subscribed by the way. Hoping more tutorials from you guys. :)
Nice work arounds. Sux I missed your classes.
Film Riot No one shows how to pull good key for moving hair (female) because with all the strands etc can you cover this? I'm sure resolution is a big factor? If shot 4k, more detailed edging etc
I do have a ? for you what kind of power bar would you recommend to use with a 4000w light setup?
Hi!! In what other videos do you talk about how to edit the chroma key with after effects?? Thank you!!
Really appreciate you showing what you use and making a recommendation. I am primarily needing one for streaming(Removing my BG as I feel it takes up too much screen room) and I feel like this might be way over kill on size for my needs. Any recommendations for a smaller fit?
Would you recommend buying the filmcity sl-3 slider as a low budget alternative to a kessler slider or something like that?
Do you key the footage and then edit? Or do you edit and then key all the shots afterward?
Super informative video! Thanks!
To light your green screen, would you use the 50w LED flood light instead? Thanks :-)
Was that a "Buried" reference at the end, too?
Best channel ever.
Raiders of the Lost Ark reference at the end!
You guys are the best, hands down.
What is that music you used during the clip of Josh folding the portable chroma screen?
4:18 would you come up with next tutorial how to clean up the noise and harsh between inner subject and the edge of subject..
Is the codec used important to green screening? AVCHD, RAW, Prores HQ.... Thanks for the video and for the answer.
Good video... I need to green screen outside of a 737 cockpit for my next short film. I am concerned about the following: Weather and lighting.

This will be very helpful for my lego animations!
The matte tip just blew my friggen mind.
Perfect! Just started working with a greenscreen!

Ryan, you will do your next episode of Film Riot in black and white!
is the track matte in after effects the same as a difference matte in premiere? I am having trouble getting the result with a track matte
These tips are so solid, as always.
I always look forward to the new episodes on Monday and "Thursday". ;-)
LOLZ.
What you just did in after affect. Didn't get any of it too fast. Can you tell some tips for chroma key in final cut pro?
Will it be harder to edit the green screen. If it is not a raw footage and only 8 bit colour video? Thank you
This is interesting but I have two questions:
Which camera did you use?
What recording format did you use? Full HD, 4K, internal recording or to an external capture device? 4:2:0 or 4:2:2?
I saw it as brand new episode and still watching it in 2020

Love the episode and love the creative live class! Was extremely informative aaaaaaaaand funny! Go Jurassic park!
what about white balance? if I use auto I turn blueish but if I set to daylight is too yellow-y. any suggestions?
So freaking helpful man, keep up the good work!
Some excellent tips in this one
Josh is so happy with himself
RYAN CONOLLY YOU ARE THE BEST!!!!!!
Trying to fold that was the bane of my existence!!! And just further proof that Josh, is a mutant!!!
Just watched a recent video and you said you were going to buy the GH4. Have you bought it? If so can you do a review/short film with it??
Hey , I want to go make night shoots in the woods with mountainbikers and freerunners. But I want to know how much light I need ? And
how can I get light in dark woods?
HOLY SHIT! That alpha matte trick is literaly a gift from god himself!!! And with god I mean you ofcourse mr ryan 'spielberg' connolly
Vomit from my brain! The matte trick is awesome! You guys rock!
Is there anything special I need to know about dealing with sheer fabrics when using green screen? Thanks I hope that's not a silly question.
hello really thanks for uploading this video!! i have a very hard time with th green screen... i crop my video from left and right, but when i put m video to a backround i see the lines where i did crop the video from left and right, how i can get over it? please help me!

I bought a chromapop and there wrinkles on it. how can I remove it?
Thanks for the great tips. I am looking to try out green screening very soon so this was really helpful. Can you tell me what mic you are using? thx
