Video Troubleshooting (Grau)

Preparing Video

1. In Looxie, right click on properties, tools, error checking. Click the automatically fix button.

2. Once scan is complete, search for "found.000" in removable disk.

3. Rename found000.CHK to the file it corresponds to (ex. 12_8ms_up1.mp4) and drag it into the subject folder on Bergelson2014-2

4. Make a new folder in the subject folder titled "corrupted" and put the .CHK file into there.

5. The "corrupted" folder should contain the originals of the corrupted files, while the main folder should contain the fixed versions of them.

Grau Processing

1. Go to the repair utility and select the "repair" action. Click the "Choose movie" button and select your video file.

2. Then click the "Choose reference movie" button and select any other properly functioning raw video file from another head cam to serve as a reference file.

3. Ensure that these options are selected in the "Options" window

4. Click "Repair" to get back to the repair window.

5. Click the "Scan" button and wait for the utility to repair the file. You should then be able to find the full repaired video in a newly created sub-directory of the source folder called "repaired."

6. Your video file should now be repaired and will play smoothly up to the moment when your camera quit recording.

Sony Vegas Processing

The corrupt file needs to be synced manually using Sony Vegas.

1. Import the video after syncing the other cameras (follow these directions while excluding the corrupt video file). Make sure you use Pluraleyes to sync the cameras before importing the corrupt file or Pluraleyes will not allow syncing

2. After the other (non-corrupt) cameras have been imported and synced, drop the corrupt camera into the workspace on a new track (see these directions if you are confused about this).

3. Delete the audio track from the corrupted file (right click, delete).

4. Make sure that you have disabled resampling before chunking the video file (explained below).

5. Change the "playback rate" to .913.

6. Split the corrupt video file into 10 minute chunks, you will adjust sync these chunks with the reference clip.

   a. Create a marker (click m) denoting the beginning of the video file after staff members have left the scene as START and again at the END after processing.

7. Start at the beginning of the first 10 minute chunk, and sync the camera with the reference file while comparing the following elements:

   a. similar visual scenes in both cameras

   b. sudden camera movements

   NOTE: If you want to drag the video to view the next segment (chunk) ONLY Click + Drag from the end.

   NOTE: If you want to drag the video to sync with the others (depending on which/how many videos you have available per file) hold ''Ctrl'' and then drag.

8. After finishing the first video chunk, continue on to complete syncing the rest of the file.

Notes:

1. You will not have a perfect sync. Be as close as possible.

2. Separate the clips into shorter chunks if you are having a hard time syncing from beginning to end of the chunk (i.e. work with 5 min chunks rather than 10 minutes). It might take a little longer but if the cameras are disturbingly off-sync you may need to do this.
