# How to fix video timestamps

## Fixing video timestamps

***NOTE:*** These instructions are for fixing the timestamps in an .opf after the video has already been checked (without using the snap-to feature to ensure accurate cell timestamps). Please use the [current guidelines for checking video annotations](/data-pipeline/video/video-annotation-checks.md)!

1. Open the file you are checking from this folder:

Fas-Phyc-PEB-Lab/Seedlings/Scripts\_and\_Apps/reliability/video/06/final\_out

1. Copy and paste the .opf into the appropriate folder Working\_Files, creating one if necessary.
   * The directory should look like this: Working\_Files/01\_06/video
   * Do not change the name of the file.\
     \\
2. Open the .opf.
   * If a message pops up that says "The following files are missing: ..." click OK, and then click "Add Data..." on the Data Viewer Controller. Navigate to the video file, following this filepath:\
     Fas-Phyc-PEB-Lab/Seedlings/Subject\_Files/.../Home\_Visit/Processing/Video\_Files/**XX\_XX\_video.mp4**
   * Under "Plugin," select "VLC Video."
   * Click OK.
3. Navigate to the first cell. Use Datavyu keyboard shortcuts!
4. Hit Ctrl + to snap to the cell. This will play just the selected cell. Fix timestamps as needed. Hit Ctrl - to unsnap the cell.
5. ***Adjust the timestamps as necessary, so that the cell contains the whole utterance and only the utterance.***
6. Navigate to the next cell and repeat steps 4-6, ***saving often*** until you reach the last annotated word.
   * TIP: If your shift is over and you're in the middle of a file, insert a comment cell saying "\[your initials] stopped here" so you can easily find where you left off when you come back.\
     \\
7. Run post-annotation checks. See here under "After annotating" for instructions.
8. Move the .opf back to the original folder (below), replacing the original version.

Fas-Phyc-PEB-Lab/Seedlings/Scripts\_and\_Apps/reliability/video/06/final\_out

1. After you finish a file, mark the Asana task complete.
