I've tried directly importing 4K footage directly into FCP7 but it doesn't play nicely in the viewer and even worse on the timeline - which I sort of expected. I'm on a MacBook Pro but it's a few years old now and doesn't look 4K footage.
So... I converted these .mov files (from my DJI Phantom 4) to ProRes HQ in compressor. They now play great in the viewer (from the bins) but horribly when dropped onto a timeline. I'm saying yes to setting timeline setting to clip setting and it's giving me a red line to ask me to render which I thought I'd avoid if I was to convert them to Prores.
I see things changed from a red line to an orange one when I change the playback settings to low. I'm not looking at editing these shots, just topping and tailing them. Any help would be much appreciated.
