I am importing 4k Raw from a canon C300 Mark II from an inferno drive. The problem is, even though I am using two mono mic tracks to audio Channel 1&2, when I import it it gives me 4 audio tracks. Since I am using proxy files (now working, thank you), I have been told that if I delete the additional audio tracks that it will not render back in 4k as the final product. Has anyone had this problem and do you know if this is true? Does anyone know how to have Premiere not import these two track as it seems the camera is unable to shut them off in 4K Raw. Thanks again to all for any insight.
All audio track modification happens after you import the original media into Premiere.
Make your proxies based on the number of audio channels on the original media. Then once you have all media in Premiere you can simply modify the number of audio tracks of all of your media by highlighting the clips in the bin, control clicking and selecting modify audio.
