I'm working out of my 2014 iMac 5K Retina computer on a project in Premiere. My client has requested this project have multiple export presets for multiple videos, particularly YouTube and Vimeo. My problem is that the QuickTime Player only plays back properly when the source is matched. Any time I try to export in a preset, the video ends up freezing or scrambled. Is there anything I can do to fix this?
Error or problem
Freeze or hang
Which version of Premiere Pro are you using? If you use a current version, you cannot harness older Mac hardware to assist your session if the source footage is H.264. For example, the iMac is too old to support H.264 hardware encoding or decoding. Try "Software Encoding" as a first step, as the presets probably are set to Hardware Encoding, which requires components that you do not have.
