Hi,

Your Blackmagic Design (BMD) acquisition card likely has the capability to receive timecode through HDMI. However, your digital camera probably cannot transmit timecode through HDMI. To confirm, refer to the digital camera's manual and check for information on timecode transmission through HDMI. If this feature is available according to the manual, then you may need to enable it in your digital camera's settings.

Warmest regards,

Hi, Eifert

We are addressing the issue of camera and tracking delay deviation after running for a period of time without Genlock tracking devices.

We successfully obtained the camera's time code through the BMD acquisition card, and then compared it with the time code of the tracking device. We found that after running for an hour, there was a 3-frame offset between the camera's time code and the tracking clock.

But the ultimate result is that the delay is not as significant as the deviation.

May I ask if you can help analyze this idea correctly?

Hi,

If I understand correctly, you operate your camera and tracking systems without any genlock. After an hour, there was only a three-frame discrepancy between the camera's timecode and the tracking's timecode.

That interpretation is correct. Implementing Genlock would prevent that three-frame variance from occurring. For prolonged production periods, Genlock would be essential to maintain constant delay. However, for example, for productions with short takes—say 1-2 minutes—and where there is an opportunity to make adjustments between takes, you can realign the delay in Aximmetry. In such cases, Genlock may not be strictly necessary.

Warmest regards,
