The Video Background Changer allows you to remove, replace, or edit backgrounds while preserving the subject in your video. This guide covers best practices, troubleshooting masking issues, and understanding your final video output format.
🪄 1. Masking an Object
If you notice that some areas are overmasked, click the switch at the top of the tool and set it to “Unmask.” Then, click on the area you want to correct. You can toggle between “Mask” and “Unmask” to fine-tune your selection.
💡 Tip: The accuracy of masking depends heavily on the input video quality. If the subject is blurry, blends with the background, or moves too quickly, masking may be less precise.
🎞️ 2. Overmasked or Undermasked Frames
If you find that some frames are not masked correctly, move the frame slider to the frame in question and repeat the masking/unmasking process until the subject looks accurate.
⚙️ 3. Masking Is Getting Worse — What to Do
If the mask degrades as you continue editing, try the following options:
- Use Auto Video Background Remover: This AI-based mode works best when the background is simple and the object is clearly visible.
- Try the Chroma Keying Tool: If your background is a solid colour, use chroma key for faster, more consistent results.
- Enhance the Input Video: Use the Video Enhancement tool (e.g., upscaling or sharpening) to improve clarity before masking. This doesn’t guarantee perfection but may help improve accuracy.
🕓 4. “Pending in Queue” Message
If you see “Pending in queue” in the Video Background Remover modal, it means our servers are currently processing other tasks. Your video will automatically start once earlier requests finish.
⚠️ 5. Black Glitches on Mac (M1/M2)
If your output video shows black glitches, this is a known macOS issue affecting systems running on M1 or M2 chips. Please contact Apple Support for the latest OS patches.
🌄 6. Best Videos for High-Quality Background Removal
The simpler the background, the better the results. Ideal conditions:
- The subject (human or object) is clearly visible.
- Minimal motion blur or compression artefacts.
- Shorter video durations (under 60s) yield faster, more accurate results.
Humans are generally the easiest subjects for clean background removal.
🎬 7. Output Codec: ProRes
The exported background-removed video is encoded in Apple ProRes, ensuring high-quality editing compatibility in professional tools like Premiere Pro and Final Cut Pro.
💻 8. Can’t Play ProRes on Windows?
ProRes is an Apple-developed codec optimised for macOS. While macOS plays it natively, Windows requires additional software:
- Use VLC (most versions support ProRes).
- Install Apple ProRes QuickTime Decoder for Windows.
- Alternatively, use a cross-platform player or transcode the video to H.264.
For best playback and editing experience, check for the latest codec packs or updates from your video player vendor.
✅ Summary
- Toggle between Mask / Unmask for precision.
- Try AI Auto Remover for complex scenes.
- Simple backgrounds yield cleaner results.
- Exports are Apple ProRes, optimised for editing.
