Now I’m worried something else is wrong as I just got a message that Time Machine couldn’t back up, saying ‘an error occurred while copying files’. Could this be related?
Anyway specs are
OS X Yosemite 10.10.5 on 20inch early 2009 machine, 2.66Ghz Intel Core 2 Duo, 4GB memory, new SSD startup disk. Is that what you’d need to know?
I am trying to export to format ‘computer’ video codec H.264 better quality, resolution 1280 x 720, audio format QuickTime movie (AAC).
Any thoughts or advice I’d be really grateful for.
