Hi,
I'm new to Vmix and it looks great.
The main problem I'm facing relates to performance and I kindly ask for your advise:
Upon opening 3 clips/players, the frame rate drops + the recordings has a lot of dropped frames.
While in project, the system indicates that the utilization is no greater than 25%, black magic disk speeed indicates 220MB/s write and 224MB/s read - so I assume it isn't due to lack of resources.
Here's the log output:

Hi,

vMix doesn't require a lot of resources, the specs you have listed are well and truly enough to handle the majority of situations, so this is a particularly strange problem.
Have you tried just playing each clip separately then adding a second clip until the problem appears?

Regards,

Martin

What are the framerates of your clips, especially: are they all the same? And what is your system frame rate? Maybe there is a difference, like mixing 24fps and 30fps sources to a 50p output...
