Hi,

The white artifact issue with the Play Pendulum/Rebound Swing effect on PNGs in the latest CapCut update is due to a compatibility problem introduced in the recent version. Since you've already tried the few basic troubleshooting steps, try out these specific solutions and workarounds:

Identifying the issue:

Since you have tried various troubleshooting steps such as clearing cache, turning off GPU acceleration etc. We need to identify the root cause of the issue. For that below few tests can identify the problem:

• New project test:
  • Create a brand new, very simple CapCut project. Import just one PNG image, apply the Play Pendulum/Rebound Swing effect, and export. Does the artifacting still occur? This helps determine if the issue is project-specific or a general bug.
• Different PNGs:
  • Try several different PNG images. Are the artifacts appearing on all PNGs, or just specific ones? If it's only certain PNGs, there might be something unusual about those files (transparency issues, embedded data, etc.).
• PNG source:
  • Check the source of PNG images. If they were created in a specific program, try recreating a simple PNG in a different program (like MS Paint or a basic online image editor) to see if that makes a difference.
• Different effects:
  • Test other effects on the same PNGs. Do other effects also cause artifacts, or is it only the Play Pendulum/Rebound Swing effect? This will help narrow down the problem.

Workarounds:

• Alternative effects:
  • Can you achieve a similar visual result using a combination of other effects in CapCut? For example, could you use keyframes to manually create a swinging motion instead of relying on the built-in effect?
  • Instead of using the Play Pendulum effect, try the Rebound Swing effect, or vice versa. Switching between these effects can mitigate the issue.
• Manual animation:
  • Import your PNG image as an overlay.
  • Use keyframes to adjust the position and rotation, creating a swinging motion over time.
  • This approach provides more control and may bypass the artifact problem.
• Pre-compose/Nest:
  • Import your PNG into CapCut. Before applying the Play Pendulum/Rebound Swing effect, create a new composition/sequence and place the PNG in it. Apply the effect to the nested composition. This might isolate the issue and prevent the artifacts.
• Image editing software:
  • If the artifact is small and consistent, you might be able to manually remove it in an image editing program after the video is exported from CapCut. This is obviously not ideal for large projects.
• External animation:
  • If the animation is relatively simple, you could create the pendulum/swing motion in another program (like After Effects, if you have it, or even a simpler animation tool) and then import the animated video into CapCut.
• Export and Re-import:
  • Export the PNG from CapCut without the effect (even if it has the artifacts). Then, re-import that exported image back into CapCut and apply the effect. Sometimes, this "baking" process can resolve glitches.

Other possible solutions:

Reverting to a previous version

• If the above methods have not worked for you then try rolling back to previous version of CapCut. While rolling back to a previous version of CapCut might resolve the artifact issue, it is crucial to ensure your current projects remain intact. Here is how you can proceed:

  1. Backup your projects:

     • Before making any changes, back up your existing projects:
       • Open CapCut and locate your project files.
       • Copy the project files and associated media to a secure location on your device, cloud or an external drive.

  2. Uninstall current version:

     • Remove the current version of CapCut from the PC

  3. Install a previous version:

     • Download and install an earlier version of CapCut. Here is the download link for the same. Choose a more recent version when the effect was working fine for you.

  4. Restore your projects:

     • After installation, transfer your backed-up project files into the appropriate CapCut project directory.
     • Open CapCut and verify that your projects load correctly.

  Please note that downgrading may lead to compatibility issues, especially if projects were created or edited in a newer version. Always ensure you have backups before proceeding.
