Adobe Bridge 16.0.4.40

Platform:

• Apple Silicon Mac

Summary:
When previewing video with the Spacebar in Bridge, audio plays normally but the video image remains frozen. Hover-scrubbing over thumbnails works correctly.

Steps to reproduce

1. Open Adobe Bridge.
2. Navigate to a folder containing video files.
3. Select a video.
4. Press Spacebar to preview.

Expected result

Video and audio both play.

Actual result

• Audio plays normally.
• Video remains frozen on a single frame.
• Hover scrub over thumbnails works correctly.

File types tested

• iPhone .MOV
• Canon .MP4
• Sony .MP4

All exhibit the same behavior.

Additional observations

• Finder Quick Look plays the same files correctly.
• QuickTime Player plays the same files correctly.
• Lightroom Classic plays the same files correctly.
• Hover scrub inside Bridge works normally.

Troubleshooting already performed

• Updated Bridge from 16.0.3.21 to 16.0.4.40
• Completely uninstalled and reinstalled Bridge
• Did not import previous preferences
• Reset Bridge preferences
• Purged thumbnail cache
• Enabled Software Rendering
• Tested with files on internal SSD
• Tested with files on external SSD
• Tested with external monitors disconnected
• Verified Adobe Dynamic Link processes are running
• Verified Finder Quick Look and QuickTime playback

Conclusion

The issue appears isolated to Bridge's video preview renderer, since the same files play correctly everywhere else on the system.
