Sync / Phase Lock Lost At End Of Run¶

Summary¶

An image-defined message at the end of a run was interpreted as lost sync / lost phase lock. This can happen if the sync pulse timing or frequency varies too much, stops, or is intermittently disconnected inside the sync path.

Symptoms¶

Message appears at or near end of run.
Sync was expected to be locked.
Camera/sync source may be unstable or briefly disconnecting.
Can be caused by sync-box internal false contact.

[7/5/2026, 11:46:09 pm] ~ Michael deAnthony: hi guys, i would like to ask, has anybody ever rigged a Sony Venice 2 Rialto on the Bolt Classic on track? Im wondering on how to manage the cable along the arm, or is it preferable to just stick with the body

[7/5/2026, 11:46:10 pm] ~ Michael deAnthony: thankss

[7/5/2026, 11:46:22 pm] ~ Łukasz Trojan: You've lost sync

[7/5/2026, 11:46:30 pm] ~ Ante: As per manual - If the timings between the system and the incoming pulse vary by too much, an error will be reported. There are two possible errors: either the frequency of the incoming pulse has varied too much in which case the system will report that synchronisation has been lost, or if the phase relationship between the system and the incoming pulse varies by more than 1/4 frame, then the system will state that Phase Lock has been lost. If this happens, then it is likely that the frequency of the sync pulse is not stable, and the computer is having trouble locking in to it. It is also possible for the sync pulse to stop completely, in this case, the computer will wait a reasonable time for it, and then will post an applicable message.
