How to Use AI to Overlay Your Video Onto a Screen?

I recently needed to overlay my video onto a screen at an angle so it looked natural and realistic. I quickly realized that AI tools can handle this automatically, making the whole process much faster and easier.

Part 1: What AI Screen Overlays Are and Why You Need Them

What AI Screen Overlays

AI screen overlays refer to using artificial intelligence to place your video onto another screen—such as a phone, laptop, tablet, or monitor—while automatically matching the correct angle, perspective, and motion.

The goal is simple: make your inserted video look like it truly belongs on the device in the scene.

Why You Need AI Screen Overlays

From my experience, creators turn to AI for angled screen overlays because the old way is slow, technical, and honestly not worth the headache. AI handles everything for you, and the results look clean and natural. Here’s why I rely on it:

I no longer need After Effects or any tricky corner pinning.

The overlays look more realistic and professional.

It’s perfect for app demos, UI walkthroughs, and product tutorials.

AI tracks moving or handheld screens automatically.

It works great for mockups, ads, UGC videos, and tech-style content.

Part 2: How I Use AI to Overlay a Video Onto a Screen at an Angle

Here’s the workflow I personally use—simple, repeatable, and basically foolproof:

Step 1: Upload the base video

Upload a clip containing the device or screen.
I’ve found that footage with clearly visible screen edges helps the AI detect the surface more accurately.

Step 2: Upload the video you want to place on the screen

This can be an app demo, UI walkthrough, gameplay, or any clip you want displayed on the device.
Most tools allow timing adjustments later.

Step 3: Select the AI screen replacement or AI overlay feature

Each platform names it differently, but the function is the same. The AI begins analyzing the screen’s angle and motion.

Step 4: Let the AI handle the perspective

At this stage, the tool automatically:
matches the screen’s perspective
adjusts distortion
tracks motion
adapts brightness and reflections
This replaces the manual work that normally takes the longest.

Step 5: Make small adjustments

Most tools offer basic controls for scaling, brightness, or color. I usually make minor tweaks to ensure the inserted video blends naturally.

Step 6: Export the final video

Once everything looks aligned, export the clip. You end up with a clean angled overlay that blends seamlessly with the original footage.

1 Luma AI — Video-to-Video

Luma AI isn’t a traditional overlay tool, but its strength lies in how well it understands camera angles. Their “change video framing and camera angles” feature is incredibly advanced. If your final output needs a cinematic feel, Luma gives you that edge.

2 HeyGen — Simple & Fast Overlay Tool

RIf I need something quick and straightforward, HeyGen is usually my go-to. It detects screens accurately and replaces them cleanly—no learning curve.

3 Runway ML — Professional Motion Tracking

Runway is amazing when the screen in the video is moving a lot. It has the best tracking out of all the tools I tried. If you have handheld shots or shaky footage, Runway handles it like a champ.

Simply upload an existing MP4 or MOV video (up to 30 seconds) and instantly transform it using a range of visual styles — from cinematic painting to cartoon, anime, or artistic textures. With its AI-driven video to anime and style transfer capabilities, you can completely reimagine your footage while keeping motion, timing, and original content intact.

Part 5: Frequently Asked Questions

1 Can AI really match the screen angle automatically?

Yes. Most modern AI video editors use surface detection and perspective analysis to identify the exact shape of a screen, even when it’s tilted or partially moving.

2 How long does an AI angled overlay take to process?

Most tools generate results in under a minute for short clips. More complex shots—such as handheld movement or rotating screens—may take slightly longer, but still far faster than manual VFX editing.

3 Can I replace the screen content with a different aspect ratio?

Yes. AI tools automatically adapt the inserted video to the screen’s shape, so even if your content is 16:9 and the device is vertical, the tool will crop or fit it correctly. Some platforms also allow manual framing adjustments.
