This page will describe the settings that are being used by TMAN for the creation of the 4k derivatives that go into NetX. These settings were worked out years ago by a former staff member of YUAG.

How the 4K derivative is created, demo with an example
Step 1: extract the color profile
convert -quiet /tmp/ba-obj-5044-8001-mas.tif /tmp/ba-obj-5044-8001-mas.icc
Step 2: create the 4k sized derivative
convert -quiet -profile /tmp/ba-obj-5044-8001-mas.icc /tmp/ba-obj-5044-8001-mas.tif[0] -strip -units PixelsPerInch -depth 8 +matte -resize 3840 -matte /tmp/ba-obj-5044-8001-mas.jpg
Step 3: add the original color profile back
convert -quiet -profile /tmp/ba-obj-5044-8001-mas.icc /tmp/ba-obj-5044-8001-mas-final.jpg
