I just upgraded to Resolve 15 Studio beta 3 and a problem that I had with the Fusion Output Cache in beta 2 seems to have found it's way to this version too.

Mainly, if I turn on User cache and the option to cache the Fusion Output , I get a Media Offline screen on the selected clips when using DNxHR LB or SQ as Render Cache Format. After checking the logs, I noticed a long list of IO Errors similar to this:

Code: Select all

[0x00003ee8] | IO                   | ERROR | 2018-05-16 08:17:52,185 | Failed to read frame frame from video frame <F:\resolve\CacheClip\bc29aa97-eb9d-484b-9db3-17d63b62f374\ff04cfac-447e-40da-bcfd-28a642725cb0\6c599d5a-e33e-4037-b90e-971b9c71c6d4\70a1aae8-f671-42c2-9696-03759d6e5094\SourceOne\564.dvcc>, error: <File does not exist, or file format is not recognizable.>

I double checked the referred cache folder above and it seems that Resolve does create it, but there are no files inside.

The logs don't seem to show any other errors that would refer to the cache.

I'm caching to an internal NTFS SSD which for version 14 worked great.

Running Windows 10
i7 6700k 4.00GHz

2x GTX 1070 8GB

I did try to find a workaround by caching the first color node instead of the Fusion Output Cache to DNxHR SQ or LB, but for some reason it only plays back at 14fps although the Fusion Output cached in DNxHR HQ for the same clip plays back at 24 fps.

Could you please post detailed logs after you have tried to cache and you see offline media.
