In a project with 1920 x 1080 resolume 4.2.1 in a osx 10.10.4 shows an output frame rate of 60 fps.
All internal content is DXV3 1080 format.
When active a video signal from a Blackmagic live, the low output frame rate to 19 fps.
We tested several blackmagic with the same result (19fps).
- Studio DeckLink 4K - DeckLink SDI 4K - UltraStudio SDI - Intensity Shuttle for USB 3.0 -
This problem occurs in two different computers.
Mac Pro 5.1 with 16GB RAM and i7 Hackintosh with 4790 K with 16Gb RAM.
If we use two computers in 770 or 680 Nvidia cards and blackmagic live video activated, the output frame rate remains at 60 fps. (nvidia drivers not installed)
Using the Nvidia 770 or 680 cards with Nvidia driver drops the frame rate to 19fps.
Is it a compatibility problem resolume with Nvidia drivers?
Is it problem really no solution???dcaiman wrote:Similar problem. No solution.
Only solution, change Nvidia card model.
This is my post with this problem: Problems with GTX970. Low frame rate.
First try updating Arena to the latest release. I can not recreate this issue with any of my machines. MBP AMD + Nvidia. PC AMD + Nvidiamiek wrote:I think I've found temporary solution for this issue.
I've tested wirecast's virtual camera out with full HD resolution as a source in resolume (Capturing 1080i50 in wirecast and sending it to virtual camera out). Works on 60fps without any fps drop. I didn't tested latency.
So I think that something wrong with Blackmagic's support in Resolume. It works OK on low resolutions but uses to much CPU on Full HD.
By the way, output to Blackmagic do not works properly too...
