I'm working with XAVC 4k in PremierePro crashes after a few minutes if not immediately. I was able to work with this project over the past few days using 4k in 1920x1080 sequence. I even was able to get out a rough cut with only one crash. The project is under 5 minutes. I believe the problem is with resizing a couple of clips. I've tried lots of trick such as copying and pasting into a new sequense, creating a new project and improting the orig project, tried different external hard drives.... Please help. Client is expecting delivery unrealistically soon.
I'm working witha MacBook Pro (mid 2012) 2.7GHz, 16GB. It had enough juice to complete a recent Red project.
Official support for that format will be arriving with the October 15th update. You may have to wait a couple weeks to get this project done.
