2-Minute Tutorial: Creating a Transition with a Matte Effect in Animation Store Creator
July 26, 2017 by Chuck Baker
NewTek multi-camera live production systems include Animation Store Creator (ACS), a software application that allows you to create custom animations and effects for your NewTek production system from images from your favorite 2D and 3D graphics applications. In this tutorial, our demonstrator shows how to create an animated wipe effect, complete with sound. The method depicted works in 3Play, NewTek IP Series and both TriCaster Standard and Advanced Edition software. TriCaster Advanced Edition is used for the demonstration, and has additional capabilities, so you may see functions on the screens not present in Standard Edition.
Also, you may find it useful to view our 2-Minute Tutorial: Creating an Overlay Transition in Animation Store Creator to learn or to refresh yourself on the introductory details for this application, as some items covered in detail there will be covered only briefly here.
Exit the live production mode to the TriCaster or 3Play opening screen. Select Add-ons from the carousel menu, and then select “Animation Store Creator” from the list of Add-ons.
On the Effect Type menu pulldown, select Wipe as the type of effect you wish to make.
The timeline will now show a simple 2-frame sequence, made up of keyframes for source A followed by source B. We can click back and forth on these to see the color-coded keyframes, red for A and blue for B.
Next, we load an overlay image sequence, saved in a format that includes an alpha channel. In this example a series of PNG files of moving rings, rendered in LightWave 3D, is used. The rings are rendered on an alpha channel background, so that video will show through in any space not covered by the rings themselves.
After loading the sequence, to ensure the effect will render correctly, it is important to know if the sequence was rendered for interlaced or progressive video; if interlaced, be sure to click on the Interlace toggle (our demonstrator covers this at the end of the video tutorial).
If we check the timeline at this point, we should find that it has lengthened by the number of the frames in the sequence. We see that the first frame is A, the second frame is B, followed by the frames of the sequence, color-coded as B since they follow the B keyframe. Source B shows through everywhere there is alpha channel.
What we want to accomplish in this case is for Source A to show through in some of the alpha channel segments and Source B to show through in other alpha channel segments. To do this, we need to use a matte image sequence. Our demonstrator loads a matte image sequence that was prepared specifically to work with the rings overlay sequence.
Animation Store Creator matte images will be simple black and white images. In our example for this tutorial, white areas will show Source A, and the black areas will show Source B.
Once the sequence is loaded, when you scrub through the timeline you can see the matte controlling the visibility of the two sources.
Now that the new Wipe effect is configured, we can take a moment and set the icon for this new effect. To do so, we move the timeline slider to a frame of our choice, and click on Set Effect Icon.
The next step is to select a quality level for the render of the effect. Three choices are available on the Quality pulldown menu:
- Normal = Standard Definition
- High = HD 720
- Ultra = Full HD 1080 For the tutorial, our demonstrator selects High.
As detailed in the previous tutorial, you also have the option to include audio in an effect. Once everything is configured and ready, you should save your work as an Animation Store Creator project file.
Once you have saved the project, use the Export menu option, to render and save the effect to your local TriCaster or 3Play, or any other TriCasters/3Plays on the same network that are in live production mode.
