Anyone else try SC (ver 18.11.18) with a decklink 4K extreme card?
Getting a strange thing… it plays perfectly until I apply a video filter, any filter, then it just stops and wont play again.
SC does not crash, still responsive but video output frozen.
Always happens after about a second or two and only way to get video output again is to delete all filters and restart SC.
Anyone else experience this?
It’s not like the machine I’m using is a flea-powered thing, specs below:
Win 7 64 Bit
HP Z840 Workstation
Xeon CPU E5-2650 V4 @ 2.2GHz
64 GB RAM
1 TB SSD
NVIDIA Quadro M6000 24GB Video Card
Blackmagic Decklink 4K extreme SDI card.
I have an Intesity 4K HDMI on Windows 10, and I am not experiencing that. It is the same API as DeckLink SDI as I have used in the past for SDI on Linux. Make sure you have GPU processing turned off. Oh wait, I just ran into while testing with the Rotate and Scale filter. It appears the driver stops scheduling frames when Shotcut drops video frames. Maybe it does not like the timestamp on the frame when a frame drops. Turning off Settings > Realtime is making it more stable for me.
Thank you, will try it out and report back.
This problem is fixed for the next release v18.12
Great, thank you will wait for the next release then.
