bik files are (obviously) not compressable. Are there any options to exclude this files from compression in UltraArc? If not, this is my suggestions to razor
TIP: To save compression time, move out all bik and sound files from Infinite Warfare folder to somewhere else, run UltraArc and set any compression you want for Infinite Warfare folder. Next step compress the folder where you put bik and sound files with none compression using UA. Last step set up Records.ini accordingly. I guess you save ~30-45 minutes of time for compression. Or compress bik and sound files with standart bat converter.
