Settings that relate to the JPEG quality you choose for your output files.
Where: Channel | Output File Formats | JPEG Quality tab
Here you can adjust the output quality of JPEG files. It is also possible to adjust the chrominance settings for each quality level. Keep in mind that these settings are channel-specific.
By entering a value of 100 the file is stored in JPEG format without any loss of data, but the file will naturally be much larger than when applying compression. Clicking Set Default resets quality settings to their original state. Note that the actual choice of output quality is set on the Main Channel Settings page.
