I purchased a brand new Sony FDR-AX33 which produces XAVC S at 100Mbit/s. PowerDirector will edit these files fine, but the timeline preview is very slow, even at low preview resolutions. I noticed that the CPU isn't being used at its max capacity and neither the GPU. I even went to the settings and disabled and enable the use OpenCL option and the use hardware decoder option, it didn't make a difference in speed. Also, I tried using either the Intel HD Graphics 4600 and switched to the NVidia GT750M. It also didn't make a difference. I used GPU-Z to measure the GPU utilization but it is always between 1% to 5%. I must use the Non-Realtime preview so I can edit correctly or else it will skip forward using the realtime preview.
My system is as follow:
Processor: Intel i7-4700MQ
GPU: Intel HD Graphics 4600 (Integrated), NVidia GT750M x2 (one integrated, the other is removable, SLI capable, Intel graphics is disabled when both cards are present in the system)
Stogare: 2TB USB 3.0 HDD (Can easily get 200MB/s of transfer rate on that HDD)
I bet this is a PowerDirector issue since the 4K files play nicely if I preview them in the Media Room, but will not in the timeline. Main Machine: Jetway NF9G-QM77, Intel i7-3610QM, Nvidia Geforce GTX 1060 3GB, 128gb SSD, Windows 10 Pro
