@shinguk > The analysis problem is likely that you have it set to NORMAL analysis mode instead of PERFORMANCE; check that box in the preferences to increase the analysis speed.
Overall, the stability is good provided you have a decent computer. Any computer older than 4 years really shouldn't even be considered for the task.
The problem I have with our recommended system specs for rekordbox is it says "Intel Core i3 / i5 / i7 / i9," but they've been making those CPUs for 12 years now, and I can tell you that even some of the early generation i7's are no longer suitable.
I have not personally tested an M1-based computer for use with rekordbox, let alone video performance, but from all accounts it's very fast. Our team is investigating the need for an Mac-silicon optimized version of rekordbox (vs. Rosetta-translated).
As for crashing, as noted, if that occurred with your AMD-based computer, we won't go near it, but if it's crashing on the Intel, then filing an inquiry ticket allows us to collect some additional data you probably don't want shared on the forums here so we can troubleshoot further and find the cause.
Thanks!
