Resolume Forum

Hi All,

I have a camera hooked up to my Blackmagic Mini Recorder card and the picture is choppy - both in the Output Monitor and on the output itself. Cam is running 720p@50 but it almost looks like it's showing in 25p with how choppy it is.

Thing is, resource usage is low and Resolume reports 60fps output at all times so I don't think it's putting much strain on the hardware.

My output is 1080 @ 60 - could this be something to do with it?

Thanks

J

Just as an update to the above, I did stay late one night and change my graphics card settings to output in 720 instead to match my SDI input, but still no dice - if anything it was worse.

Open to ideas - I do prefer to output 720 from my ATEM but I can always run it through a Decimator before it reaches Resolume so that I can scale it to match? Or are there other settings or hardware issues I should be looking at first?

Cheers,

Jay

How does your input look like in Blacmagic Media express?

Could you describe your hardware setup, what kind of machine you're using and what kinds of outputs?

Hey Zoltán,

The input looks exactly the same in Media Express, this weekend I ran the input through an SDI distro first so that I could see it direct into a monitor and also see it via the PC and the monitor is just so much smoother.

Specs are as follows:

• Windows 10 Pro
• i5-3470 @ 3.20Ghz
• 8GB RAM
• 64 Bit O/S
• 256GB Seagate Barracuda SSD
• NVIDIA GeForce GTX 660 Ti

Weird thing is, when the video does get really choppy, Disk, CPU and Mem usage remains really low. Memory doesn't peak past 60% use, CPU around 25%, GFX card usage around 60%.

I'm willing to upgrade any part of the system to get this working reliably, but just don't want to invest in something that won't make any difference.

Cheers,

Jay

Has anybody got any ideas on this? I just can’t seem to get SDI video input to be as smooth as it is ‘not’ via my PC, even though specific resources aren’t being maxed out

So, does the output look also choppy in Media Express?

Yes, exactly the same.

did you try setting your graphics card output to 50Hz as well?

Sounds like a case for BMD support, if Media express is also choppy.

The Mini recorder is thunderbolt 2 right?
How do you connect it to your windows machine?

No, it's the PCIe version
