When I import a clip, the video is fine but audio requires a render. I looked a clip properties (48khz, 32 bit floating) but don't see option for 32 bit float in the sequence settings. Any thoughts on how to lose the need to render?
32bit? Where did this audio come from? You need to change it to 16 or 24 and then bring that into FCP. Or find another audio application that supports it.
