Pulling Off the Perfect Green Screen (Chroma Key) in Adobe Premiere Pro CC 2017

====================================================================

Green screen, also known as chroma keying, is an essential post-production technique used extensively across various forms of video production. From feature films to vlogs and everything in between, mastering this skill can greatly enhance your final output by allowing for seamless compositing over complex backgrounds.

In Adobe Premiere Pro CC 2017 (CC being Creative Cloud), the process couldn't be more straightforward thanks largely due with their intuitive Ultra Key filter which we'll explore below:

### Step 1: Import Your Footage

Begin by importing both your green-screened clip and background footage into Adobe Premiere. Make sure that the green screen is recorded against a solid, even-colored backdrop - typically either blue or green (hence why it's called chroma keying). Avoid using patterns or multiple colors as these can cause unwanted artifacts during post-production.

### Step 2: Apply Ultra Key Filter

Once both clips are imported into your timeline, select the layer containing just the foreground element you wish to isolate from its background. This could be a person talking head against an green screen for example. To access the Lumetri Color Effect panel where we'll find our magic wand - click on 'Effect' > 'Video Effects'> 'Key & Stabilize'> 'Ultra Key'.

### Step 3: Adjust Ultra Key Settings

Within this new window, you'll see several sliders and drop-down menus that allow for fine-tuning of your chroma keying results. The main areas to focus on are:

* Threshold: This slider controls how sensitive the algorithm is when identifying areas within each frame as either foreground (your subject) or background. A lower value will result in more aggressive removal but may also pick up unwanted details like hair or clothing textures.

* Color Temperature: Adjust this wheel if necessary to account for any color cast present due differences between your camera's white balance settings during recording.

### Step 4: Preview & Refine

Once you've applied the Ultra Key filter and adjusted its parameters accordingly, preview your edited clip in Premiere by hitting 'Spacebar' or pressing play on the timeline scrubber bar. Observe how well the chroma keying has worked - if there are any remaining artifacts such as fringes around edges of objects or parts still showing through that shouldn't be visible (such as background details bleeding into our subject), simply fine-tune these areas using lasso tools within Premiere's Timeline panel until satisfied with final output.

In conclusion, mastering the art of chroma keying in Adobe Premiere CC 2017 is easier than ever before thanks to their robust Ultra Key filter. By following these simple steps outlined above and taking some time experimenting with its various settings, you'll be pulling off professional-looking green screen composites like a pro!
