What does the ‘Video frame dropped’ message mean?

There has been a momentary loss in video signal, most often due to bad cables. This error may be preceded by ‘Video CRC errors’ during monitoring. 

If a ‘Video frame dropped’ error happens during a take the recording will stop. Note that if the camera is sending a record trigger signal to the Onboard then it will start recording again after a frame drop. Therefore always check your recordings if you see the ‘Video frame dropped’ message.
