I installed the K-Lite mega codec pack v. 10.3.0.0 in the hopes of expanding my encoding capabilities and options. I use MEP 2014 plus at work and Pro X 6 at home. I've since had problems encoding to mp4 or Quicktime mov. at work I've uninstalled the codec pack at work as well as run a registry cleaner (CCleaner), but the problems persist. During the uninstall I was prompted to close both MEP 2014 + and MS Outlook. I clicked OK at the prompt thinking it meant, OK, I will close the programs. In fact it was saying OK, the programs are closed, proceed with the uninstall. So the uninstall may not have been flawless, and is why I checked for registry errors afterwards, and rebooted after that.
At home on Pro X 6, i WAS able to encode to mp4, but not to mov
I'm looking for insight or past experience with this situation. I'm not 100% sure the two are related.
