So they are XAVC in a MXF? I’m just trying to figure out the video codec. h.264 is really processor intensive – especially at 4k. I don’t use XAVC or an F7 – but I think that it uses a form of h.264, you can correct me if I’m wrong. But you can use MediInfo app to find out what the codec is – or VLC should even tell you. But, yes, in the instance of h.264, ProRes or DNx are better options for editing. Then if you have a lot of effects on top of it, and a number of large still images, you will slow down the processing considerably on any system. Adobe/FC/AVID – but I’m guessing Resolve as well…
