Blackmagic Design have just released the latest update to DaVinci Resolve. If you have been experiencing crashes when using XAVC material from the PXW-FX9 I recommend you download and install this update.
If you are not a Resolve user and are struggling with grading or getting the very best from any log or raw camera, then I highly recommend you take a look at DaVinci Resolve. It’s also a very powerful edit package. The best bit is the free version supports most cameras. If you need full MXF support you will need to buy the studio version, but with a one off cost of only $299 USD it really is a bargain and gets you away from any horrid subscription services.
