Video Turns Black When Applying Preset Adjustment – Any Fix?

Hi,

From the video you provided, it appears you are encountering an issue in CapCut where the video turns black after applying a saved preset adjustment. This is a known occasional bug within video editing software, including CapCut.

Here are some common reasons this might happen and potential solutions:

Possible Reasons:

• Corrupted preset data: The saved preset itself might have become corrupted, leading to display issues when applied.

• Software glitch: It could be a temporary bug or a compatibility issue between your CapCut version and the video file/device.

• Resource limitations: Applying complex presets can be resource-intensive. If your device is low on RAM or processing power, the preview might fail to render correctly.

• Conflicting adjustments: If the preset contains adjustments that conflict with existing video properties or other effects already applied, it might cause display errors.

Common Causes & Fixes

1. Corrupt or incompatible preset

Cause: Your saved preset might reference parameters or filters (like LUTs or effects) that no longer exist or conflict with the current CapCut version.

Fix:

• Recreate the preset from scratch using the latest version of CapCut.

• Avoid stacking too many intense adjustments like extreme exposure + contrast + shadows.

• Test each adjustment one at a time before saving as a new preset.

2. Missing/Invalid LUT or Effect

Cause: If your preset includes a LUT or a resource that's missing from your system, it can cause the preview to go black.

Fix:

• Go to Settings → Resource Folder and check if any LUTs/filters used in the preset are missing.

• Try applying the preset to a different video format (MP4, MOV, MKV) and see if it still turns black.

• If it contains a custom LUT or overlay, reimport that manually before applying the preset.

3. HDR/Color Profile Conflict

Cause: The video file might use a color space (like BT.2020, HDR10, or HLG) incompatible with the preset’s adjustment curve.

Fix:

• Convert your video to Rec.709 SDR using a tool like Shutter Encoder or Handbrake.

• Alternatively, in CapCut PC:

  • Right-click the video → Color Space → Try converting to SDR.

  • Then apply the preset again.

4. Hardware Acceleration/Rendering Bug

Cause: GPU-related bugs in CapCut can cause rendering issues, especially with Radeon GPUs or under "High Performance" mode.

Fix:

• Turn off Hardware Acceleration:

  • Go to Settings → Performance → Turn off Hardware Acceleration.

• Or, switch your graphics preference for CapCut:

  • Windows: Settings → Display → Graphics → CapCut → Set to "Power Saving" or "Let Windows decide".

5. Preset File Corruption

Fix:

• Open your preset, note down its values (Brightness, Contrast, Saturation, etc.).

• Re-apply these manually to a new clip.

• If it works, save as a new preset and delete the old one.

Other Fixes:

1. Create a New Preset: Try to recreate the problematic preset from scratch. Apply the desired adjustments manually to a test video, and then save them as a new preset. This can help rule out corruption in the old preset.

2. Check for Conflicting Effects: If you have other effects or adjustments already applied to the video clip, try removing them before applying your preset. Then, re-add them one by one to identify any conflicts.

3. Simplify the Preset: If your preset is very complex (e.g., many layers of effects, extreme color grading), try simplifying it to see if a less intensive preset works. You can then try adding adjustments back incrementally.

4. Clear CapCut Cache: Sometimes, clearing the application's cache can resolve display issues. The method for doing this varies by device (e.g., in Android, go to App Info > Storage & cache > Clear cache).

5. Reinstall CapCut (Last Resort): If none of the above works, you might consider uninstalling and reinstalling CapCut. This will give you a clean installation, but remember to back up any important projects if possible.

If it’s still happening

If none of the above works, try this workaround:

1. Import your video.

2. Screenshot or write down your preset's values.

3. Manually input those values again (don’t use the preset).

4. If it works → save as a brand-new preset.

5. Delete the old one.

By systematically trying these solutions, you should be able to identify and resolve the issue with your CapCut presets.
