# Analyze recorded video

Offline Analysis organizes recorded video into cases you can search, review, and export. Start with one short clip before processing a batch. These steps use the Watch desktop app.

## Prepare a video

Check that local AI is ready and the computer has space for the source video and results. Use a playable MP4, MOV, M4V, AVI, MKV, or WebM file. In a multi-user deployment, an operator or administrator account is required to create cases.

## Create a case

1.  Open Offline Analysis in the sidebar and select New analysis.
2.  Enter a recognizable case name and select a mission. Add Custom instructions if needed. Keep the other analysis settings for the first test.
3.  Choose Private, Restricted, or Team visibility. If you link a camera source, its access restrictions also apply to the case.
4.  Click the video area to select a file, drag videos into it, or choose a folder. Check the listed filenames and count, then select Start analysis.
5.  The case opens after upload and validation. Check progress and Per-file results, then wait for Full analysis reports to appear. Keep Watch open.

Folder selection includes supported videos in subfolders. More concurrent workers can increase load; verify that one video completes reliably first.

## Find and review a moment

1.  Describe what you want to find, such as “person wearing yellow.” Review the interpreted filters, remove incorrect ones, or use Advanced filters.
2.  Open a result card and check the source video, timestamp, and surrounding frames. Use View source video to verify the observation against the recording.
3.  With edit access, bookmark a result or add a note for later review.

Search covers completed analysis results. If it returns nothing, clear the filters, check processing status and per-file errors, then inspect the original video. An empty result does not establish that the event is absent from the recording.

## Pause, resume, or retry

*   Pause an active case. Use Resume on a paused or cancelled case to continue from saved progress.
*   For a failed case or a case with failed files, review the per-file errors and select Retry failed files. Failed files restart from the beginning; existing results are retained.
*   Controls depend on the case status and your permissions. If a control is missing, ask the owner or administrator to check your edit access.

## Export or delete a case

With export access, open Export at the top of the case and choose JSON, CSV, or Complete evidence ZIP. Open the download and check the case, timestamps, and evidence. Delete case is available only with delete access; confirming it permanently removes the case, source videos, and all results.

## If analysis cannot start or fails

*   Start analysis is disabled: select a supported video and wait for discovery or upload to finish. A 360 case requires a fixed sampling interval.
*   No completed reports: check Per-file results. Verify that the source plays, local AI is ready, and disk space is available, then retry one short clip.
*   A case is missing or export is unavailable: check case visibility, member access, and linked-source permissions.
