Creating an App Demo Video

🎬 1. Plan Your Video

• Script or outline: What do you want to show and say?
• Sequence: Start with you introducing the app on camera, then switch to the screen recording with your talking head in the corner.

📹 2. Record Yourself Holding the Phone (Intro Clip)

• Use a webcam or a camera/phone on a tripod.
• Record yourself introducing the app and maybe showing the phone in your hand.

📱 3. Record the Phone Screen

On Android:

• Enable Developer Options > USB debugging.
• Use scrcpy (excellent open-source tool) to mirror and record your phone’s screen: scrcpy --record file.mp4
• Optional: Add --show-touches to display where you tap (can be toggled in Android Developer Settings too).

On iPhone:

• You’ll likely need to use QuickTime Player on macOS, or a capture card. (This part is hard on Linux/Windows.)

👇 4. Add a Virtual Finger or Pointer

• If you enabled “Show touches” in Android developer settings, you might not need anything more.
• Otherwise, you can overlay a graphic (e.g., a transparent PNG of a finger) in video editing software at key moments.

🖼️ 5. Picture-in-Picture (Your Face in the Corner)

• Record your webcam video separately while you demonstrate the app.
• Use video editing software to place your webcam video in the bottom-right corner over the screen recording.

🧰 6. Editing the Video

On Linux:

• Kdenlive — full-featured and user-friendly.
• Shotcut — also good and cross-platform.
• OBS Studio (for live recording + PiP, less editing).

You can:

• Trim, cut, and arrange clips.
• Overlay your webcam footage in a corner.
• Add titles, transitions, background music, etc.
• Add an image overlay for a “virtual finger” if needed.

📤 7. Export and Upload to YouTube

• Render to MP4 with H.264 codec.
• Use a good thumbnail, title, and description for better engagement.
