I'm not sure if this is a SC issue or exists for all controllers. I have a 64gb sd card in my SC, but have not paid any attention to the cache.This morning I was in the middle of a 200 pic hyperlapse when a message popped up saying the cache was full. My setup writes RAW frames to the M2P SD card which was a freshly formatted 64gb. The hyperlapse continued and it appeared to go through and complete the "synthesize video" process yet no frames were recorded on the M2P SD since the time when the cache message appeared. Why should the SC cache prevent the recording of frames to the AC SD card ? I get that it didn't write anymore to the SC cache, but it seems reasonable to continue writing to the AC SD, especially since the hyperlapse process continued. I have since changed the cache settings.
