Now, we are going to apply a mask so that the white layer only appears through the shape of the bird. In your precomposition layer window, click on your "Alpha" footage and drag and drop it above the White Solid you have just created.Ģ.9. In the Solid menu, change the color to pure white and hit "OK".Ģ.8. To do that, go to the top menu bar, and select " Layer / New / Solid.".Ģ.7. You should now have something like this.Īll right, now we need to extract the alpha channel from this footage.Ģ.6. Rename it something clear, like "Alpha_precomp". To do that, simply drag and drop the footage to the "Create a new Composition" button at the bottom of the panel.Ģ.5. Now we are going to create a precomposition with this footage. Now "Right-Click" on the duplicate, and select "Rename" to rename the footage as "Alpha".Ģ.4. Click on the video you have just imported, and hit "Ctrl + D" to duplicate it. Create a new project, and drag and drop your video on the left part of the screen.Ģ.3. For this tutorial, we used the 2018 version (15.1.2).Ģ.2. If you don't know After Effects and need to know the shortkeys for Mac, you can check them out on .Ģ.1. The commands we are going to give you in this section are for Windows. In the console, type this command, replacing "video_extension" by the actual name and extension of the video you have downloaded.įfmpeg -i video_extension -vf "split, pad=iw*2:ih, alphaextract, overlay=w" -y final_name_alpha.mp4 There, "Double-Click" in the url address bar so as to delete everything and write "cmd" instead.Ģ.3. When Ffmpeg is installed, go to the folder of the bird video you have downloaded in the first part of this tutorial. If you are on Mac, then follow this tutorial by ProgrammingKnowledge2.Ģ.2. If you are on Windows, follow this tutorial by SharedTutor. However, it is not very user-friendly, so here is what you have to do.Ģ.1. without needing to re-render it through After Effects or any other video editing tool. Process your video ¶ First Method : Ffmpeg ¶įfmpeg is an amazing, free and open source little tool which enables you to do a multitude of operations on a video. So how are we supposed to do that? Well, here is the first, simplest way. In the end, to be processed correctly, your transparent video must look like the "alphabird_alpha.mp4" you can see below. However, in order to interpret it correctly, Minsar Studio needs the alpha channel to be separated from the RGB channel, and put right beside it so that Minsar Studio can re-assemble it its own way. Save it on your computer.Īs you can see in your explorer, the miniature of the video shows the bird on its black background. Click on the video you want, and then on "Free Download". For our part, we liked the little bird.ġ.5. You will see a certain amount of videos with a black background. If you download a green screen video, you can be almost certain that you will have to delete the green screen first (which, in fact, does prevent any bad surprise later on :))ġ.4. On the top right corner, type "Alpha" in the search bar, or "Green screen". But for now, let's pretend the video is already transparent : you'll find out rather quickly if it's not.ġ.3. The task to separate the channels will have to be done first. There are a few of them for free, but beware : some of them are indicated as "alpha", but are not already transparent. In this tutorial, we will go and fetch a transparent video on the Internet. The simplest one is through Ffmpeg, the other one is through After Effects.īut first, let's go get that nice bird transparent video! Create your transparent video ¶ In this tutorial, we are going to see how to do that in two different ways. Indeed, you have to transform your transparent video a bit so that Minsar can understand that it has to interpret it as a transparent video. This tutorial is about the second step : how to prepare your already transparent video for Minsar. But this is not the point of this tutorial, and there are already plenty of guides on the internet to do such a thing (how to delete a green background for instance). You can do that through a certain number of ways, through After Effects for example. But in the case of a video, you have two steps : first you have to make sure that your video has no background. To import a transparent image in Minsar Studio, you have to make sure it has no background, and export it in ".png" from Photoshop or similar software.įor a video, it is basically the same thing. How to use a transparent video in Minsar Studio ¶Ī transparent video is like an image with an alpha channel, that is to say an image with a transparent background. Second Method: After Effects CC 2018 and Media Encoder
