    What to do if AJA Recording Equipment drops frames during record?
    • N
      nortonamyAug 1, 2025
      If you're experiencing dropped frames during recording, it could be due to a few reasons. One potential cause is that the RAID system cannot sustain the data rate required by the capture preset codec. Another reason may be that virus checking software is running in the background; if this is the case, try disabling it. Also, verify that the scratch drive is correctly set to the RAID.
