Remove Background doesn't work

Hi,

It seems you are encountering a problem with CapCut's background removal features ("Customized cutout" / Penghapusan khusus and "Chroma key" / Kunci Kroma) on the desktop version, where the cursor disappears on the preview screen and the features don't work.

Based on the image and your description, here are several potential causes and troubleshooting steps you can try:

1. Check Project and Clip:

   • New Project: Try creating a completely new project and import the same video clip. See if the background removal works there. This helps determine if the issue is with the specific project file.
   • Different Clip: Test the feature with a different video clip entirely. This can help identify if the problem is related to the specific video footage you're trying to edit.

2. How Chroma Key Works:

   • For the "Chroma Key" feature, you usually need to first select the color you want to remove. Click the color picker tool (eyedropper icon) next to "Color Picker" (Pemilih warna - although not fully visible in your screenshot, it should be there) and then click on the color in the video preview window that you want to make transparent. After selecting the color, you can adjust the "Strength" (Kekuatan) and "Shadow" (Bayangan) sliders. Make sure you have selected a color first.

3. Customized Cutout ("Penghapusan khusus"):

   • This tool requires you to "paint" over the subject you want to keep. If the cursor isn't appearing when you try to paint, it might be a bug or a display issue.
   • PRO Feature: Notice the "PRO" label next to the brush options under "Customized cutout". While Chroma Key is free, the advanced Customized Cutout requires a CapCut Pro subscription for full functionality. If you don't have Pro, the tool might be disabled or limited, although the cursor disappearing is unusual behavior and still suggests a potential bug.

4. Cursor Visibility Issues:

   • Check Accessibility Settings: Certain accessibility settings can interfere with cursor visibility in CapCut. Specifically, features like large cursors or high contrast modes may cause the cursor to disappear within the application. Try disabling these settings to see if the cursor reappears.

   • Application Focus: Ensure that CapCut is the active application on your screen. Sometimes, the cursor may not display correctly if the application is not in focus.

5. Check System Resources and Drivers:

   • Close Background Apps: Ensure no other demanding applications are running in the background that might be consuming too much CPU, GPU, or RAM.
   • Update Graphics Drivers: Outdated or corrupted graphics card drivers can sometimes cause display issues in video editing software. Check the website of your graphics card manufacturer (NVIDIA, AMD, Intel) for the latest drivers.

6. Background Removal and Chroma Key Issues:

   • Proper Lighting and Contrast: The effectiveness of background removal tools heavily depends on the contrast between the subject and the background. Ensure your subject is well-lit and stands out distinctly from the background. Increasing the contrast and brightness can aid the algorithm in accurately distinguishing between the two.

   • Manual Adjustments: If the automatic background removal isn't yielding satisfactory results, consider using CapCut's manual cutout or masking features. This approach allows for more precise control over the areas you wish to remove or retain.​

7. Restart Everything:

   • Close and reopen CapCut.
   • Restart your computer. Sometimes temporary glitches can be resolved with a simple restart.

8. Update CapCut:

   • Check if you are using the latest version of CapCut. Developers frequently release updates to fix bugs. Go to CapCut's settings or menu to check for updates.

9. Reinstall CapCut:

   • If none of the above steps work, the installation itself might be corrupted. Try uninstalling CapCut completely, restarting your computer, and then reinstalling the latest version from the official source.

Start with the simplest steps like restarting the application and your computer, then move on to checking for updates and testing with different projects/clips before trying driver updates or reinstallation.
