I purchased maximum version of this program (Video Converter Ultimate) in order to convert H.265 4k material to Apple ProRes for further processing. This program is a cheater: During conversion it apply additional contrast to the original material: 1. Black point level goes down at least 10 points, which destroys details in shadows. 2. Probably the same trick is used on opposite. As a result, converted material looks a bit better from the beginning. But in fact, details in shadows are gone, and colour are incorrect. Also i can not see any advantage in conversion speed (MacBookPro 15 late 2014). Again cheating. Verdict = useless. Please refund.
