I'm having serious issues trying to convert material shot in 4K HD with the Red Rocket. I get "error decoding frame" errors. In software it works fine (albeit slow) so this is a Rocket issue.
I've tried reinstalling the latest firmware and driver and naturally I'm running the latest version of everything.
See attached screenshot for error messages.
I have a still frame extracted that gives the same error. Available for download from my dropbox: STILL.R3D
