[Config Support]: Thumbnail playing wrong alert video recording

[Raven-Luminari]

Describe the problem you are having

I have several alert thumbnails showing in the Review screen, some (not all) play the wrong video when I select them. I have confirmed that the I can export the correct video, and is available in the filesystem. all recordings have the same owner:group of root

rebooted the container & unRAID. Some thumbnails play the correct videos. Frigate has been running for several months, but this is not a new problem.

Based on the available documentation, I don't have specific information about thumbnails playing incorrect video recordings in the Review screen. However, I can suggest some troubleshooting steps based on related issues:

Potential Configuration Issues:

Your configuration shows pre_capture: 1 and post_capture: 5 under detections(1). These settings control what video segments are retained around detected events(1). If pre-capture is too short, the video might not align properly with the thumbnail timestamp.

Recording Retention Settings:

Your current configuration retains recordings for 14 days with mode: active_objects(1). The recordings are stored at /media/frigate/recordings with the folder structure YYYY-MM-DD/HH/<camera_name>/MM.SS.mp4 in UTC time(1). These recordings are written directly from your camera stream without re-encoding(1).

Recommended Actions:

1. Try increasing pre_capture to at least 5-10 seconds to ensure sufficient video is captured before the event(1)
2. Verify that your storage (/mnt/user/frigate/) has adequate space and proper write permissions
3. Check if the issue occurs consistently with specific time periods or randomly
4. Consider temporarily enabling mode: all instead of active_objects to ensure continuous recording and rule out gaps in footage(1)

Since you can export the correct video and it exists in the filesystem, this suggests the recordings themselves are intact but there may be an indexing or playback issue in the Review interface.

For additional help with this specific issue, you may want to visit GitHub to report this behavior, as it appears to be a UI-specific problem not covered in the current documentation.

[hawkeye217]

You don't have a fast object detector defined in your config, which means you are using the CPU detector for object detection. This is not recommended, and may be a major contributor to your issue.

I've enabled openvino, and changed the pre-capture. Will monitor. Thanks for speedy response.
