Hi,

First, make sure that you are using Blackmagic Desktop Video version 12.5.1 or higher.
(Desktop Video version 14.2. or higher if using Aximmetry 2024.3.0 or higher)

Next, test the input by using only the Video Input module in Aximmetry. Do not set any specific Mode or set it to AUTO:

If the image quality is still poor, set the resolution and frame rate of the Mode parameter to the same as used in Blackmagic Desktop Video:

If you continue to experience issues, we need a clearer image of the input to diagnose the problem. You can capture video as a PNG image in Aximmetry using the Video Recorder module. Make sure the Video Format is set to PNG, and use the Snapshot trigger button to capture the frame:

Additionally, if you can capture what you observe in Media Express and your Blackmagic Desktop Video settings, that would be helpful.

Alternatively, you could try updating to the latest Aximmetry.

Warmest regards,

Thank you so much. I will try that. Meanwhile, I've already managed to get a proper image by taking the HDMI video output from the camera and converting it to SDI. It's strange that the HDMI with a converter works fine, but the direct SDI output from the camera doesn't. This is probably related to the camera's SDI output when switched to 4K, as the SDI works fine in HD.

Anyways, thanks again.

Kind Regards,

Alain

Hi Alain,

Note that 2160p at 25 fps cannot run on 3G-SDI; it requires at least 6G-SDI. If you are using 3G-SDI, that could explain why it works with the HDMI converter or when outputting in HD. However, since you didn't experience the same issue in Media Express, it is likely that you are already using 6G-SDI or a higher.

Warmest regards,
