Default Clip Recall timecode Problems

We are using a K2 with a dyno controller in a mobile truck. The problem we are having is an intermittent issue, when recalling a clip, the (A) and (B) angles recall correctly, but the (C) and (D) angles recall with a much different time code... varying from 30 sec to 1.5 minutes in the difference. It follows always on the back C and D channels on any clip. This seems to happen at random, approx 1 every 8 productions.

Any suggestions?

Please make sure to report this to Tech Support. It is important to open a case so that there is accountability to fix. Either call - 1-800-547-8949 or use the web portal http://www.grassvalley.com/ad/contact_customer_support

Have not heard of this before. What version of Summit and Dyno are you running?

What timecode source are you using?

If TC is plumbed from an external TC generator, it should only be feeding to one TC port on the back of the Summit. In many installations, all four TC ports are being fed, and this not the proper setup for intended replay.

I have the same issue here for k2, it started just yesterday when all of the sudden c is not recalling properly. A and B is always fine for recalling they gave accurate data but C do not.

To start with,
1. what version of Dyno/Summit are you using?
2. what is the timecode on Summit set to look at? LTC, sysclock, VITC
3. when this happens, could you describe the workflow, and is it repeatable all day long, or once in a while in a day?

We observed a similar problem on a BTN game tonight on 22HDX. It appears that when they cleaned the fiber on one of the cameras the associated time code for that camera got out of sync. We suspect that this can be cleared by restarting a session. Wonder if cameras that pull and go to another drop tend to get out of sync on TC.

Default Session Restart not necessary

This would be expected performance for a couple of reasons. The main one being that there currently is no built-in Frame Sync in Summit. The other is that the selection for TC was something other that SYS clock.

Typically you are going to be using LTC or VITC so...when this happens, go to the HOME screen, and Shift+Rec Stop (then Live again) instead of a session restart. This should kick the "new" LTC back into time.
