Hi there,
I've just installed the SMSP 16 and there is a problem with preview lag, but only when I try to edit raw footage recorded in XAVCs format coming right from my Sony a6400. The preview works perfectly smooth with other video formats such as AVCHD.
I have to admit that before I decided to upgrade to Movie Platinum 16, I had been using Movie Studio 12, and then everything was fully operational. No issues with the preview. Recently I also made a PC format, and reinstalled my Windows 7 64bit and I must have forgotten about installing some codecs or something crucial needed for video editing, because right now neither the 12 version nor the 16 want to work with XAVCs format.
It would be great if there was someone willing to suggest some possible solutions. I installed every single driver, K-little codeck pack, tried to change dynamic RAM preview etc.
I use a PC with 32 GB of RAM, i7 4790K, Radeon R7 260X.
