Clips from my Sony A6700 (MP4) randomly show a frozen frame in the timeline, while audio continues normally. The playback is unusable.
Hi everyone,
I’m dealing with a critical issue in Premiere Pro that completely blocks my editing workflow.
Problem:
Clips from my Sony A6700 (MP4) randomly show a frozen frame in the timeline, while audio continues normally. The playback is unusable.
Details:
• Camera: Sony A6700
• Format: MP4 (XAVC S / XAVC HS)
• Freeze frame occurs during playback in timeline
• Audio plays fine, video is stuck or updates inconsistently
Important observations:
• The issue persists even when using proxies (ProRes Proxy)
• Exported video is completely fine → this seems to be playback-only
• If I re-encode the source file and use “Replace Footage”, the clip in timeline turns black (no video at all, audio remains)
What makes this worse:
• This started in the middle of editing a large project
• Replace Footage doesn’t work → I can’t relink properly
• I basically can’t continue editing
What I’ve tried:
• Clearing media cache
• Restarting Premiere
• Re-importing files
• Using proxies (ProRes Proxy)
• Updating Premiere and system
Additional note:
The issue appears in multiple Adobe projects and persists after updates.
At this point I’m honestly stuck and quite desperate — this project is time-critical and I have no way to continue editing.
Has anyone experienced this or knows what could cause it?
Any help would be hugely appreciated
