One of the things about using motion graphic elements is their ability to drastically change the appearance of your footage. For example, I can have a clip of a woman break dancing in a studio, which is a good piece of stock footage. If I were to drop a motion graphic clip of blinking lens flares or perhaps an abstract grunge clip vignette, it would definitely spice things up a bit. Now, some of these motion graphic clips may come with transparency and some may not. That’s not to say it’s any better or worse to have either but should you need to remove a black or white background from your mo-graph clip and a blend mode is not enough, here’s a solution. I will show you how to create 2 presets you can use for removing either a black or white background efficiently. Below is quick voiceless video tutorial demonstrating what steps were taken.
Matte Remover Presets
In order to create this preset, I will use two motion graphic clips, one with a black background and one with a white background. I have 2 items from Rampant Media Design. I will use a transition from their Flash FX collection and a clip from their Grunge FX collection. In my timeline, I have a Flash FX transition on top of 2 video clips. This transition has a black background throughout its animation – because of this, we don’t see any of the video clips underneath. Let’s remedy that.
I will show how to create a Matte Remover Black preset. Go to the Effects browser and type in Set Matte. Let’s apply the filter to the transition. Change Use for Matte from Alpha Channel to Luminance. Leave everything else alone. Next, go back to the Effects browser and type Remove Matte. Apply the filter to the transition and make sure the Matte Type is set to Black. Now, if we play our timeline around the transition occurring you’ll see that it no longer has its black background.
This same process can be used for white backgrounds as well. In my timeline, I have a Grunge FX clip over some dancer footage. Right now, you can’t see anything because of the white background and black grunge texture. Let’s take out the white background by creating our Matte Remover White preset.
To eliminate the white background, all I have to do is apply the Set Matte and Remove Matte filters on this clip. Use the same settings for the Set Matte filter like before except click on the Invert Matte checkbox. For Remove Matte, change the Matte Type to White. Now, all you will see from the clip are the black grunge patterns.
To turn these effects into presets for future use, all you have to do is follow these steps. First, highlight the Set Matte and Remove Matte filters in the Effect Controls panel. Right click on either filter and select Save Preset. Name the preset to whatever you choose. For this example, I will name it Matte Remover Black and then hit OK. Repeat these steps for the Grunge FX clip and call that preset Matte Remover White. Now, whenever you have motion graphic clips that don’t have built-in transparency, you can use these presets to take care of that.
