We have a 4 camera replay set up, all at 1080p 50, and the replays quite often start to jump on our rig.
Specs:
12th Gen Intel® Core™ i7-12700 (25 MB cache, 12 cores, 20 threads, 2.10 GHz to 4.90 GHz Turbo)
32 GB, 2 x 16 GB, DDR5, 4400 MHz
NVIDIA® GeForce RTX™ 3070, 8 GB GDDR6, LHR
1TB M.2 PCIe NVMe SSD

I since bought a WD_Black SN750 4TB SSD just for replays thinking this would fix the issue, but it still persists.


Any fixes or workarounds would be great. I read another post about potentially turning off recording whilst we play a replay. This isn't ideal, but would be a better solution if I could get some advice on how to implement this?

Thanks.

I suspect that your CPU is too slow and does not meet the minimum system specs for vMix 4 camera Instant Replay:

It is the major reason why laptops are not recommended for use with vMix Instant Replay.

Same issue here.

I have recreated this with a single NDI camera. Sometimes it stops, starts, stops, starts. Sometimes it goes fine.. then speeds up at the end.

I have found an issue where Windows defender is scanning the USB ports for virus' and slows the band width down to a crawl. This may be the same for LAN but I am not sure. My tech told me to download malware bytes and use the free version and this will uninstall defender. In testing it has made a huge difference. I will try it in production tomorrow and get back with the results. 90% Better in production.
