Correct DRS™ VTR I/O Troubleshooting

There are numerous reasons why an ingest or layoff can fail within Correct, though typically speaking there are two main culprits: Slow or failing drives and misrouted or incorrect sync. Below is a guide to diagnosing and resolving these issues, along with some of the less common ones.

##Bad Drives
Slow or failing drives can impact both ingest and layoff

###Test disks within Correct

The easiest way to test whether bad or slow disks are causing problems is to do a test ingest with disk I/O turned off. You can also do a No Disk I/O layoff, but it will output blank frames to your tape, so you should substitute a scratch tape.

  1. In the Bin Manager, right-click and select Clip Record
  2. In the Recording window, click the Debug button
  3. Click record Into Clip/No Disk IO

If the ingest succeeds, that points to a problem with your disks.

###Check Disk Health in Windows

  1. Right-click My Computer and select Manage
  2. Choose Disk Manager
  3. Review the health of all the drives that make up your ImageStore volume

##Bad Sync
Bad reference signal will most often affect layoff (ingest defaults to use internal sync), and will produce a number of “Timecode mismatch” error messages in the Record Details window

To test:

  1. Disconnect any SDI video coming in to the video board.
  2. In the Bin Manager, right-click on your clip and choose Clip Record
  3. In the Record Dialog, select Direction = Into VTR
  4. Click the Debug button.
  5. Click the Record To VTR/Internal Sync button to do a debug layoff.

If the recording succeeds, that points to a reference signal. To confirm:

  1. Reconnect the video input. Record out using Debug > Record To VTR/Internal Sync.
  2. In the Bin Manager, right-click on your clip and choose Clip Record
  3. In the Record Dialog, select Direction = Into VTR
  4. Click the Debug button.
  5. Click the Record To VTR/Internal Sync button to do a debug layoff.

If the layoff succeeds, the reference signal is the problem
If the layoff fails, the incoming video signal is interfering with the reference

In either case, contact a facility engineer for help

##Other less common problems

Wrong VTR Preroll

Your VTR must be set to a Preroll of 5

###Bad tape, cable or router
Try swapping out tapes, cables and patching directly to the VTR to rule these out

###Overheated DVS card
The Record Details window will show a temperature reading at the beginning of the recording.
Note: There are occasional “false positives” so rule out the other possibilities before looking to the DVS card
