I Have updated from previous version (Mountain Lion to Yosemite) and from zero and I have Premiere constantly crashing as well. Did the latest CUDA upgrade today and I think it’s even worst.
I have GeForce 650M on a MBPr early 2013.
It depends, maybe the codec is not suported by The TV.
I have send material to TV channel with DVCPRO that were original from 24p material with no problem.
It’s normal because your monitor is progresiv and your material interlazed. Old TVs where interlazed to save bandwith but now new TVs can show both I and P.
So If move your project file it does´t matter as long as what you open is your duplicate and not the original. Keep a copy of what you are moving in it´s original place but make sure you change the project settings to your new place.
It depends, if you have free Vimeo then you can’t upload a 1080p, only 720p movie but with Youtube you can.
I would say go with 1080p unless you are planning to upload to Vimeo only.
