Blurring Edges in Ultimatte Advantedge
Ultimatte Advantedge is a compositing software that allows video correction filtering, also known as VCF, for digital video formats such as 4:1:1, 4:2:0 and 4:2:2. VCF allows you to restore color information that was lost while compressing the video formats, as well as reduce artifacts found on the blue or green screen composites with the help of DV footage. Whenever editing in Advantedge, follow these steps.
Step 1: Open Compatible Software
You can choose from a long list, but Advantedge works best with Adobe After Effects. Open the program and click Open/Load project.
Step 2: Load Advantedge Plug-In
Go to Effects and Presets, and select your desired plug-in from the dropdown menu; in this case, choose the Ultimatte Advantedge plug-in and load it.
Step 3: Replicate Background
Replicating the background in your foreground helps you with editing in an easier and faster way. Simply go to Effects->Channel ->Set channel option. Set the RGB channels from foreground to background by selecting each channel and placing it to the background. Check the RGB box.
Step 4: Do a Check-Up
Your foreground should be the same as your background now. If you turn off the background, you should see the shapes from your foreground. You can now start blurring.
Step 5: Gaussian Blur Option
Next, you will need to blur the foreground by creating a nice smooth feathered edge with the Gaussian Blur tool. Go to Effects, Blur and Sharpen, and choose the Gaussian Blur option and adjust its value. Make it as realistic as possible. Too much Gaussian blur can produce unwanted effects on your footage.
Step6: Inverting Option
Go to Effects, Channel and choose Invert option. You should only invert the alpha channel, so right-click the Invert button and choose it. This inverts the colors and allows you to work faster on the image.
Step 7: Channel Composite Option
The next thing you need to do is add a Channel composite. This removes everything outside your image, making it a “clean” cut.
Step 8: Stencil Alpha Option
Again, go to Effects, choose Channel and then choose CC Composite. Right click it and choose the Stencil Alpha option.
Step 9: Screen Option
After adding the Stencil Alpha effect, add one more CC composite. Again, go to Effects, click Channel and choose the CC Composite option. This time, right click it and choose the Screen option instead of Stencil Alpha option.
Step 10: RGB box
Uncheck the RGB box that you checked previously on Step 3.
Step 11: Final Touches
Zoom in your image and check to see if the blur has been evenly applied. Make use of blur buttons if you want to blur edges or simply go through the same process again for an intensive edge blur.
Step 12: Final Result
Turn on the background layer that has been turned off on Step 4. You can see that the foreground looks feathered when placed in front of the background.
