Importing Your Video into Blender

Alright, guys, the first step in our background removal adventure is to import your video into Blender. This is super easy! First, open Blender. You'll likely see the default scene with a cube, a camera, and a light. We don't need those for this project, so let's get rid of them. Select each object by right-clicking on it and press the 'Delete' key or 'X' key, then confirm the deletion. Now, you should have a clean, empty scene. To import your video, you'll need to switch to the 'Video Editing' workspace. You can find this at the top of the Blender interface, likely in the 'Layout' dropdown menu. Click on it and select 'Video Editing'. This will change the layout to show the video editing timeline and preview windows. Now, click 'Add' in the top left corner of the timeline window, and select 'Movie'. Navigate to where your video file is saved on your computer and select it. Blender will then import your video. You will see the video appear in the timeline as a strip. You can now scrub through the timeline to view your video, and you can also see the preview in the viewport. If you don't see the video preview, make sure you have the 'Preview' option selected in the top right corner of the viewport. Also, it's good practice to save your project at this point. Go to 'File' > 'Save' and choose a location to save your Blender file. Saving frequently is always a good idea to prevent losing your work. Now that your video is imported and ready to go, we can move on to the next exciting step – setting up the compositing nodes to remove the background.

Setting up the Compositing Nodes

Okay, team, now it's time to get into the heart of the matter: setting up the compositing nodes. This might sound intimidating, but trust me, it's not as complex as it seems. In the Video Editing workspace, switch to the 'Compositing' tab at the top. You'll see two nodes by default: 'Render Layers' and 'Composite'. We need to add a few more to handle the background removal. First, make sure 'Use Nodes' is checked in the compositing window. If it's not checked, check it now. Next, add a 'Movie Clip' node. Press 'Shift + A' to open the 'Add' menu, go to 'Input', and select 'Movie Clip'. Click 'Open' in the 'Movie Clip' node and select your video file again (yes, we're importing it a second time, but it's important for the compositing process). Connect the 'Image' output of the 'Movie Clip' node to the 'Image' input of the 'Render Layers' node. You also have to connect Render Layers' Image output to 'Composite' node Image input. After this setup, add a 'Keying' node. Press 'Shift + A', go to 'Key', and select 'Keying'. Connect the 'Image' output of the 'Movie Clip' node to the 'Image' input of the 'Keying' node. This node is our magic wand for removing the background. The 'Keying' node uses a color key to select a color, which will become transparent. Now, the fun begins! We're nearly done setting up the nodes. Finally, connect the output of the 'Keying' node to the 'Image' input of the 'Composite' node. Now, make sure the output of the 'Render Layers' node is still connected to the 'Image' input of the 'Composite' node. If everything is connected correctly, the node setup should be complete. With these nodes set up, we're ready to select and remove the background color, and create the transparent background that makes the subject appear as if it's floating. Isn’t that neat?

Keying Out the Background

Alright, let's get down to the nitty-gritty and key out that background! This is where the magic really happens. With the 'Keying' node selected, you'll see a bunch of settings in the node's properties panel (usually on the right side of the screen). The most important setting here is the 'Key Color' selector. This is the color that the 'Keying' node will make transparent. Now, you need to select the color of the background in your video. The easiest way to do this is to use the eyedropper tool next to the 'Key Color' selector. Click on the eyedropper, then click on the background color in the preview window (the background in your video). Blender will sample the color you clicked on. You'll see that the background starts to become transparent in the preview window. Don't worry if it's not perfect yet; we can fine-tune it. Now that you've selected the key color, we need to adjust the settings to get a clean key. Experiment with the 'Threshold', 'Similarity', and 'Blend' settings in the 'Keying' node. Increasing 'Threshold' will remove more of the selected color. 'Similarity' affects how similar a color needs to be to the key color to be removed. 'Blend' softens the edges of the selection. Play around with these sliders until the background is as transparent as possible without affecting your subject. You might need to make small adjustments to all three settings. The goal is to get a clean cutout of your subject. Sometimes, you'll need to refine the key further. You can use the 'Dilate/Erode' setting to expand or shrink the selection, and the 'Despill' setting to reduce color spill (like green reflections on your subject if you were using a green screen). Take your time and make small adjustments. The more careful you are, the better the final result will be. Once you're happy with the key, we can move on to the next step: adding a new background. This is where you can get creative and place your subject in any environment you desire.

Adding a New Background

Time to get creative and add a new background! Once you have keyed out the original background, the subject should appear isolated. Now let's place this isolated subject on a new background. This can be an image, a video, or even a solid color. First, add an 'Image' node. Press 'Shift + A', go to 'Input', and select 'Image'. Click 'Open' in the 'Image' node and select the new background image you want to use. This could be a photograph, a graphic, or anything you like! If you want to use a video as your background, you'll need to add another 'Movie Clip' node, just like we did for the original video, and select your video file. Next, you need to 'mix' the keyed-out subject with the new background. Add a 'Mix' node. Press 'Shift + A', go to 'Color', and select 'Mix'. Connect the 'Image' output of your 'Keying' node to the top 'Color' input of the 'Mix' node. Connect the 'Image' output of your 'Image' or 'Movie Clip' node (the new background) to the bottom 'Color' input of the 'Mix' node. Set the 'Mix' node's 'Mode' to 'Over'. This will place your subject over the new background. Finally, connect the output of the 'Mix' node to the 'Image' input of the 'Composite' node. If you want to use a solid color background, create a 'Color' node. Press 'Shift + A', go to 'Input', and select 'Color'. Select the color you desire by clicking on the color swatch. Connect the 'Color' output of the 'Color' node to the bottom 'Color' input of the 'Mix' node. This will place your subject over the solid color. Play with the 'Factor' setting in the 'Mix' node to adjust the transparency of your subject. Now, preview the final composition to ensure everything looks as you desire. You can add effects, adjust colors, and get really creative. Congrats! You've successfully added a new background and are one step closer to finalizing your awesome video!

Rendering Your Video

Okay, guys, we're in the home stretch! The last step is rendering your video. Rendering is the process of turning all the compositing and editing you've done into a final video file. Before rendering, go to the 'Output Properties' tab (the printer icon) in the properties panel (usually on the right side of the screen). Here, you can set the output format, the file path, and the output resolution. In the 'Output' section, click on the folder icon to select where you want to save your video and name the file. Under the 'Format' section, choose your desired video format. 'FFmpeg Video' is a good all-around choice. In the 'Encoding' section, select your desired codec. H.264 (MP4) is a common and versatile codec. You can also adjust the output resolution to your desired size. The resolution is the number of pixels wide and high the video will be. Generally, you want it to match the source video's resolution. Now, go back to the 'Compositing' tab. Make sure your final 'Mix' node is connected to the 'Composite' node. In the 'Render' menu at the top, click on 'Render Animation', or use the shortcut 'Ctrl + F12'. Blender will start rendering your video, frame by frame. The rendering time will depend on the length of your video, the complexity of the scene, and your computer's processing power. While rendering, you'll see a progress bar. Once the render is complete, your video will be saved to the location you specified. Congratulations, you've removed the background in Blender and rendered your final video! Now you can upload it to YouTube, share it on social media, or anywhere else you'd like. Be proud of what you've created. Go ahead and start experimenting with different backgrounds, effects, and edits to create videos that will wow the audience!
