Has anyone achieved smooth 60fps into VDMX over USB? I get skipped frames which is a problem as I’m doing image magnification onto large screens. To date I’ve had mostly good success with Blackmagic devices at 60fps but annoyingly they don’t support my camera at 1080p60, only 720p60.
I’ve tried the AJA UTAP-SDI and Magewell SDI adapter - which do work with my camera - but usually drop numerous frames, while occasionally doing 60fps for a stretch. I’ve messed with the render settings but not found a combination that improved things.
VDMX drops frames at all resolutions when at 60fps, so it’s not strictly a performance issue.
Using OBS with buffering on I get smooth 60fps but after a substantial delay.
I’m currently using a 2015 MacBook Pro (but have a 16" on order :-).
My hope is that VDMX can do 60fps somehow but with less buffering than OBS.
Not sure about the 60’s… but using several sources here same time…
Got good and tons of bad adventures with professional hardware in many ways already…
… started to use IOS devices as input/browsers… (like older and newer iPad’s)
works much better and faster in re/connection /even after crashes!!!
… like for GoPros as separate router per cam + input…
… or way much more content you are able to connect and display…
It was a “Magewell USB Capture SDI USB 3.0 HD Video Capture Dongle Model XI100DUSB SDI”.
I did try the Magewell utility but didn’t find anything obvious to change there. Because OBS can receive 60fps without dropping frames (after a delay that’s so long it’s unusable) I think the problem is a buffering/handshaking issue on the USB/VDMX side.
I can’t say. I remember having good luck with the “Magewell USB Capture HDMI Plus”, but that is HDMI only. When I tested the 4K version, it was awful, but maybe not for this. “Magewell USB Capture HDMI 4K Plus Device.” How does CamTwist handle the live input?
It sounds dumb, but maybe there’s another way to get your feed into syphon and then share it with VDMX. (I’m also on a 2015 MBP w/ OSX 10.12 16GB).
Thanks very much for the additional details. I did try that Mokose SDI adapter last year but ultimately returned it as I was searching for lowest latency (my main application is Image Magnification) and my Thunderbolt based BlackMagic UltraStudio Mini had lower latency and resource usage. However, I don’t recall having frame-drops at 60fps, so perhaps I should get another to try…
