I think a great feature would be to introduce hardware video decoding when playing video files in vmix. (h264 and h265)
Hardware video decoding is supported in nvidia gpus, amd gpus and intel(igpu).
In nvidia it is called NVDEC.
In amd it is called UVD or VCN. on intel it is quicksync/
Hardware video decoding is now supported in premiere pro ( on intel ) or premiere pro beta version (nvidia and amd gpu).
It is supported in davinci resolve studio. It is supported in videofile player mpc-hc.
It will be great feature, that HW decoding will be also in vmix.
This will decrease CPU usage.
