SDI trigger record on 7" Video assist with Ursa via teradek?

Hi,

I shot with an Amira recently and the SDI trigger record worked flawlessly on the Blackmagic Video assist 7"

Amira > Teradek 300 TX > Teradek 300 RX > Blackmagic video assist 7" (All via SDI)

But I've never been able to get it to work with the Ursa mini 4.6k. Does anyone have experience with this working?

Thanks
Jon

You need to set the Ursa. I I to T/C Record (default is T/C Run) before T/C record trigger will work on the VA.

Hi Denny, How do you change the timecode settings in the URSA as you mentioned? Can't find it in the menu!

Ursa Mini 4.6k - PL

Cheers

Not sure which menu, but you can look it up in the camera manual, under Timecode, or call your BM Regionals support office. I do not have an Ursa, and my camera menus are different from the Ursa, but all BM cameras have this setting ability to choose between T/C Run (also known as Freerun) and T/C Record setting.

In Menu/Settings/Reference select External. On the HUD, the timecode is normally displayed as current clip duration. Tap that and it will switch to a free running display of time of day with a little TC indicator to the right of the TC display on the HUD.

Hold your finger on that for five seconds and it will switch to timecode record run. The switch back by holding for three seconds.

The behavior should be similar to what is described on page 52 for the Pro in the June edition of the manual. More details there.

Edit
I can switch the HUD from clip Duration to Time of Day, but I can't get it to go to Timecode Record even though Setup indicated External. Maybe that only works when you have a TC connection plugged into the camera.

Is that helpful, Jon?

Hi Rick,

So are you saying the hold for 5 seconds doesn't work on the non pro mini 4.6k? Holding for 5 seconds on the touch screen doesn't do anything more me. I'm pretty sure record on the ursa mini 4.6k can't be triggered on a VA via a teradek bolt 300

The Teeradeck bolt 300 may be the issue, not passing the T/C correctly to the VA. That would be my thought on this. Try connecting the camera directly to the VA and see if T/C record trigger works? If so, then the Bolt 300 is the issue.

Yeah the trigger record works fine Ursa > BNC > VA

The trigger record works fine with an Amira > teradek TX > Teradek RX > VA

I might email Teradek to see if they can get it working with the Ursa.

Sounds like the best bet. Good luck,
Cheers

Jon, glad USRA > VA worked fine.

Just came across this thread.
Exactly the same problem, and similar setup:

Red Epic > Swit S4915T > Swit S4915R > Videoassist 5"=works flawless, trigger rec and stop everytime (always on sdi)

Ursa Mini Pro > Swit S4915T > Swit S4915R > Videoassist 5" = Cannot trigger rec on videoassist

I've tested several sdi cables, downgrades firmware on Videoassist, changing TC settings on the Ursa, and nothing works...

Any solution I could try?
Thanks in advance,

Joaquin

Digging up an old thread - this appears to also be an issue when using the Canon C200. I contacted Canon and they confirmed SDI triggering works on an Odyssey 7Q / Apollo in their tests but they didn't have a BMVA 4K to test.

I'll reach out to BM support but figured I would see if anyone else is experiencing this.

Yeah I've never had the Ursa work either with a video assisting triggering record via a Teradek. I recently updated the Teradek and this still didn't work. Hopefully future Ursa firmware will address this.
