TLDRIn this tutorial video, viewers learn how to expertly remove green screen backgrounds and integrate AI-generated backgrounds to create a natural scene. The video, sponsored by Riverside, introduces the AI Magic Clips feature, which uses AI to identify the best moments in a video, trim them, add captions, and prepare them for social media. The process involves using Adobe After Effects and Photoshop to key out the green screen, refine the edges, and blend the lighting. A 4K vertical sequence is created in Photoshop with generative fill to generate a custom background. The final composite includes a blurred AI background with light wrap effects for realism and a color grade for a polished look. The video concludes with tips on editing and a call to action to explore more AI editing tools and podcast editing techniques.

Takeaways

🎨 Green Screen Removal and AI Background Creation

This paragraph introduces the video's focus on removing green screen backgrounds and creating an AI-generated background that blends naturally with the scene. The tutorial begins with a sponsored mention of Riverside's AI Magic Clips feature. It emphasizes the common issue of imperfect green screen backgrounds with shadows and highlights. The process involves using Adobe After Effects and the Keylight effect to select the screen color, focusing on the darkest part for a better key. Further refinement is done by adjusting screen matte to remove gray particles and clipping blacks and whites for a cleaner result. The video also addresses issues like edge particles and spill (green screen reflection on skin), and suggests using 'reduced chatter' and 'screen pre blur' for smoother edges. The paragraph concludes with a transition to creating a fake AI podcast background using Photoshop, where a 4K vertical sequence is generated with generative fill to create a custom background.

📹 AI Magic Clips and Final Compositing Touches

The second paragraph discusses the AI Magic Clips feature by Riverside, which scans videos to identify the best moments, trims them, adds captions, and prepares them for social media. The process is demonstrated using an interview recorded earlier, showing how to refine edits and customize captions. The paragraph also provides a discount code for Riverside. Returning to After Effects, the focus shifts to making the AI background more realistic by adding a camera lens blur and a light wrap effect using a free plugin by Production Crate. The background is adjusted for a subtle wrap effect, and exposure is tweaked for a less intense look. The final step involves adding an adjustment layer with a Lumetri color effect or a custom color grade from the Premier Gal Toolkit to enhance the overall color and mood of the composited scene. The paragraph ends with a reminder about the impact of editing techniques and a prompt to explore more AI tools and podcast editing tips.

Keywords

💡Green Screen

A green screen, also known as a chroma key screen, is a technique used in video production where a green-colored background is filmed and then replaced with another image or video during post-production. In the video, the green screen is removed to create a transparent background for the subject, allowing for a different background to be added.

💡AI Background

An AI background refers to a background image or scene generated by artificial intelligence. In the context of the video, the AI background is created using generative AI in Photoshop, which is then composited with the video to create a realistic scene.

💡Keylight

Keylight is an effect in Adobe After Effects used for chroma keying, which is the process of removing a certain color (in this case, green) from the video and making it transparent. It is crucial for removing the green screen background and is used by selecting the darkest part of the green screen to ensure a clean key.

💡Screen Matte

Screen Matte is a part of the Keylight effect that allows for further refinement of the keying process. It helps to adjust the foreground and background to achieve a pure white foreground and a completely transparent background by clipping blacks and whites, thus removing any remaining gray particles.

💡Spill Suppression

Spill suppression is a technique used to reduce or eliminate the unwanted reflection of the green screen color onto the subject in the video. The term is used in the context of Keylight's advanced options to clean up the intermediate key result and prevent green reflections on the skin.

💡AI Magic Clips

AI Magic Clips is a feature provided by Riverside, which is a video editing tool. It uses AI to scan videos, identify the best moments, trim them, add captions, and prepare them for social media posting. In the video, it is used to quickly create highlights from an interview.

💡Camera Lens Blur

Camera Lens Blur is an effect that simulates the blur that would typically occur in a camera lens, giving a more realistic and professional look to the composited AI background. It is applied to make the background appear out of focus and blend naturally with the foreground.

💡Light Wrap

Light Wrap is an effect that adds a soft glow around the edges of an object to simulate the way light wraps around physical subjects. It is used in the video to blend the subject with the AI background by creating a subtle light effect on the subject's edges.

💡Lumetri Color

Lumetri Color is a color grading tool in Adobe After Effects used for color correction and color grading. It allows for adjustments to color, saturation, and exposure to enhance the visual appeal of the video. In the video, it is used to apply a color grade to the final composite to match the mood and style.

💡Generative Fill

Generative Fill is a feature in Photoshop that uses AI to fill selected areas with synthetic content that matches the surrounding pixels. It is used in the video to create a custom AI background by describing the desired scene to the tool.

💡Podcast Editing

Podcast editing refers to the process of editing audio content for podcasts, which can include tasks such as trimming, arranging segments, and adding sound effects or music. The video touches on podcast editing in the context of using AI tools to enhance the editing process.
