I also got the message ""Error encountered during optimized media generation" with 12.5 Studio using RAW footage. I solved it by re-mounting the SSD I was using as a cache, and making sure the path to the media storage location was set correctly under Preferences | Media Storage (I had changed the volume--cache is best left permanently attached). I believe there is another thread that addresses issues with h.264 specifically,but you might check to see if your problem is specific to h.264 by trying another format to see if it reproduces there as well. If so it could be the cache volume or path issue (could also be cache volume full or corrupted).
