Uncompressed audio with significantly compressed video

Hi there,

I need uncompressed audio and significant video compression for 4K 60FPS material. What codec / setting would you recommend. Prores 422 Proxy gives me too big files, h.264 compresses audio, but if I choose "Quicktime" in Adobe Media Encoder and then separately h.264 as video codec (which allows me uncompressed audio option) the resolution is limited to 2000x2000.

Am I doing something terribly wrong?

Thanks in advance for your answers!
