Green Screen Movie FX Comes to the iPhone

 In Apps

App Advice has a write-up on an interesting app from epocfield called Green Screen Movie FX. Can you guess what it does? No? Perhaps they should have named it something more descriptive, like “This is an app that lets you accomplish green screen FX on an iPhone like the one you’re now looking at right now.

Green Screen Movie FX has an easy to use interface and only costs a couple bucks. It allows users to composite and record LIVE video over existing video. Some nice backgrounds are provided with the app, but the real power is being able to use your own footage for the background.

Once you’ve finished your composite, you can easily share it in a number of ways.  Good stuff!

Green Screen Movie FX

--As featured in new and noteworthy in the UK iTunes entertainment section--

Now you have the power of a Hollywood special effects studio in your pocket (well, almost!).

The app gives you the ability to use an special effect known as Chroma Key or Green Screen in a simple, fun and quick way. Simply select multiple colors in the viewfinder by tapping the screen and instantly replace it with a video or picture of your choice.

Imagine replacing the sky with a scene from space showing a planet spinning or changing the view out of your window into Niagara Falls.

Green Screen lets you create special movie effects and instantly share and show off your video creations on Facebook, Dropbox, Twitter, email and others.

The app comes with the following videos built in:

o Group of hot air balloons in flight
o Spectacular water fountain display from Las Vegas
o Tranquil beach with palm tree rustling in the breeze
o Flying through clouds especially for super hero movies!
o View of the earth rotating through space
o Slow motion fire explosion
o Amazing firework show
o Cloudy mountain - amaze your friends with your climbing prowess
o Niagara Falls
o Paris with the Eiffel tower in the background
o A plane taking off from an airport
o Forest Mountain scene
o South Beach Los Angeles with life guard hut

As well as built in videos, you can also import videos & pictures of your own. Amaze your friends by appearing in a starring role alongside your favorite movie or pop star. Or show them your holiday to the seven wonders of the world without actually having been there.

App Features:
o Real time compositing of videos / images with iPhone video camera.
o Use rear or front camera.
o 13 in-built effects videos
o Use you own videos / photos from the iPhone camera roll.
o Import movie clips from iTunes.
o Change the amount of background color replaced live with tolerance slider
o Choose up to 3 different colors to replace with green screen fx.
o Fine turn the chroma key’s red, green, blue values
o Record videos and share them straight to Facebook, Dropbox, email, iPhone gallery
o Highly customizable options including capture resolution, chroma match quality, camera focus mode
o Choose from Best Quality (multiple chroma key points) or Best FPS (one chroma key point) in Settings

Praise for Green Screen:
"You know those big, blockbuster Hollywood movies that use “green screens” to make actors look like they’re somewhere they aren’t? Now, for $1.99 Apple fans can take advantage of a similar feature..."

"Does Green Screen Movie FX offer enough quality to warrant the two dollar price-tag? And the answer is—certainly! The app offers the best chroma keying I’ve seen on a mobile device..."

"Once you've finished your composite, you can easily share it in a number of ways. Good stuff!"

Enjoy and amaze your friend and family.

Works great on the iPad2!

Please rate the app to ensure future update and new features!

TopTip! if you have a newer more powerful device go to settings and make the block size smaller and resolution higher for better quality!

--Important please note that this app is only support on currently released versions of iOS--

    Hi Taz,

    I’m the author of the app, Just wanted to point it uses live viewfinder not STILL images for the foreground the chroma key is replaced by a video in the background either from the 13 inbuilt or one your drop in iTunes / iPhone Gallery.

    Looks Great! Thanks, Taz!

  • JennyCam82

    wow! i’ve been looking for a chromakey application. i found a few others in the store, but this looks much better. does it work with ipad?

  • Taz Goldstein

    Hi JennyCam,

    The app’s description in the App Store lists iPad as a compatible device. But it’s not a universal app, so it isn’t designed specifically for the iPad. Like all non-universal iPhone apps running on an iPad, it will appear smaller on the iPad screen. I’m guessing it works well with the iPad 2’s camera, but I’m not certain. If Graham is still around, perhaps he can confirm?


    P.S. No prob, BlueGun! 🙂

    I haven’t got an iPad 2 but at least one of the reviews posted on iTunes says it works.

    So it ‘should’ work 🙂 , plus iiPad 2 is dual core so if you play with the quality settings you may get better results than on iPhone4.

  • DJ

    Great to see a developer this responsive!

  • Dan

    Love it, just tried it. I had a similar question about iPad2 , as I was seeing slower playback when I upped the chromakey points on my iPhone. I’ll have to try it out.
    I would like to see a way to delete background videos. The list can get a little long.

  • Graham

    The extra chroma points do slow down the capture FPS, you can go back to one by selection ‘best fps’ in the options.

    It works really well on iPad 2 seems about twice as fast.

    A new update is coming in which you can delete imported videos.



  • Graham

    Hi Dan, It’d be amazing to see what it’s like in a real green screen environment.

    The videos the app uses are really quite low resolution 480×360. It’s limited by the amount of processing that’s required to apply the effect per pixel , per frame.

    I Was thinking of an upgrade in the future to do offline chroma key as well which could obviously do 720p @30fps.
