![]() Exporting your video from After Effectsġ. On the other hand, if I exported the final video without one, After Effects would default to filling the transparent area around the white, bouncing ball with a black background. However, if I turn off the red background layer so that only the white bouncing ball layer is active and I export the final video with an alpha channel, the background will be completely transparent. Since the red background fills the entire After Effects composition, if I were to export a final video, there would be no transparency in the video, even if I included an alpha channel. The animation consists of two layers - the white, bouncing ball layer, and a red background layer. In After Effects, I have created an animation of a white, bouncing ball. Now that you have an idea of what an alpha channel is, I’ll show you how to export them from After Effects CC, followed by Premiere Pro CC. If it had not been added, the editing program would have defaulted to adding a solid black background where the transparent areas should be. The alpha channel was added during the export of the motion graphic title to create a transparent top and bottom in this specific title sequence. The first few frames where the motion graphic file animates in requires having one to see the footage layer below. To help you understand exactly what they do, here are 3 screenshots that show the progression of a motion graphic with an alpha channel starting to animate onto footage. When to use oneĪlpha channels are really great when you’d like to send a completed motion graphic file like a lower thirds title from one program and use it in another. MOGRT files in After Effects to use within Premiere Pro, as shown in this tutorial.) For the purposes of this post, we will focus on exporting and using motion graphic video files. This is a site sponsored by a corporation, and advertising for other companies is probably not good form (besides being against the rules).Let’s start with the basics - an alpha channel is essentially a transparency map for your footage or image, meaning that you can have areas in your footage or image that have some level of transparency, or total transparency.ĭepending on the editing program you are using, there may be an option to work with the project file to avoid exporting and including alpha channels (like creating. Now that I have started to update it again, I expect the visitor count will rise again. It has cut way back since I have not been updating it. I used to get a LOT of visitors every day. And you might want to suggest how to test it as well. Feel free to send me an email from my web site telling me why people should use it and what you want people to know about it. If I like it, I will post a link on my web site to direct people to it. I am just a techie dabbling on the creative side of things.īy the way, I suppose I should get around to testing your product. ![]() But that is because other people are more creative than I am. And I would probably use a downloaded template as a starting point. Of course, having said that, if I was going to have a complicated title with motion, I would use AE to begin with. ![]() ![]() I used to count the downloads, but over the years I lost track. I have a link to his styles on my web site. If you are interested in the font style I used, it came from Tim Kolb back in the CS3 days or before. Perhaps you would care to explain your comments in more detail? Where is the problem? Why go to TIFF? I certainly would never " export normally and key out the backgrounf (sic) in AE" I don't mean to start an argument, but making a title is easy, exporting it with an Alpha channel is easy (as shown above). I don't see what is complicated about it at all.
