I put a video on to compressor, and applied the MP4 setting to it. When I go to the audio tab, there is an option to choose the quality of the audio, which I always choose 'BEST' for.
However, there is also a 'bit rate' tab, which is 64kbps by default. Surely the 'Quality' and 'bit rate' are the same? Or is the bit rate option just there for more precise adjustments? If so, would my 'BEST' quality setting mean a higher bit rate than 64kbps?
