Want a clean, editable background for your AI talking video? With VisionStory, you can add a green screen as a post-processing upgrade—generate your video in standard quality first, then apply a solid green background you can key out in any editor. This tutorial shows you exactly how to add a green screen to your video, step by step, without regenerating from scratch.
Why Add a Green Screen After Generating Your Video
Instead of choosing a green screen before you create anything, VisionStory lets you generate a standard talking video first, review it, and only then apply the green screen. That means you can test your script, voice, and character cheaply, and spend extra credits on the green screen background only once you are happy with the result. The output is a solid green background that is easy to remove with chroma key, so you can drop your AI presenter onto any scene. For a full overview of the feature, see our green screen video page.
How to Add a Green Screen to Your AI Video
Step 1: Generate a Standard AI Talking Video
Start by creating your talking video in standard quality. Choose or upload your character, add your script or audio, and generate. Standard videos are faster and use fewer credits, so this is the ideal moment to test different scripts, voices, and expressions before committing to any upgrade.
Step 2: Open the Post-Processing Options
Once your video finishes generating, open it and look for the post-processing options. From here you can enhance the video you already made—there is no need to re-upload your character or regenerate the whole clip.
Step 3: Select Green Screen
- Green Screen: Apply a solid green background to your finished video, ready for chroma key editing.
- Optional HD upgrade: If you also want sharper output, you can apply the HD upgrade in the same post-processing step.
VisionStory processes your existing video and swaps the original background for a clean green screen, keeping your presenter, lip sync, and motion intact.
Step 4: Export Your Green-Screen Video
When processing is complete, download the green-screen version of your video. You now have a clip with your AI presenter on a solid green background, ready to bring into your editing tool of choice.
Step 5: Replace the Background in Your Editor
Import the exported clip into a video editor that supports chroma key, such as CapCut, Premiere Pro, Final Cut, or DaVinci Resolve. Apply the green-screen chroma key effect, remove the green, and drop in any background you like—a product shot, a branded scene, a slideshow, or footage of your own. Fine-tune the key and spill settings until the edges look clean, then export your finished video.
Tips for a Clean Green-Screen Result
- Preview before you upgrade: Review your standard video first so you only spend credits on the green screen once the script and delivery are right.
- Keep the key tight: In your editor, adjust the chroma key threshold and edge softness to avoid green fringing around hair and shoulders.
- Match the lighting: Pick a replacement background whose lighting and color temperature match your presenter for a believable composite.
- Reuse the same video: Because the green screen is applied in post-processing, you can go back and add HD or other enhancements to the same clip without starting over.
Adding a green screen to your AI video is the fastest way to place a lifelike presenter into any scene you can imagine. Generate your talking video with VisionStory, apply the green screen in post-processing, and take full creative control of the background. Ready to try it?
