Hi Scott,
I was able to play back a file that I exported from After Effects. I had imported a clip from the Hyperdeck SSD, did an effect to it, then exported it using Quicktime format options “Uncompressed YUV 10 bit 4:2:2”.
I’m not sure if you have to do this part, but I then copied it over an existing file on the SSD with the same name. This played back on our unit.
I should say ours is a recent purchase (not sure of rev.) in case there was some change in how it handles files.
