I’ve been playing with proxies a bit as I’m editing on a 2008 MacPro a w/4 internal drive 8gb raid and a Geforce GTX 680 card. It’s slow… I’ve created a proxy for the 4k camera file that is 1/4 size ProRes LT. Here’s what I know so far:
I copy all my camera cards to a 2 disk raid that is set to mirror, that way I have 2 HDs with all my camera files for eternity… I always copy the camera files to the 8gb/4 drive raid for editing. There is an option in the ingest settings to “Copy and Create Proxy” which is what I’ve done for the first time with my most recent project. It takes awhile and slows down the Mac but it does put both the original file and the proxy on my raid.
I have to make the sequence 4k. I added the button in the source and program windows to toggle back and forth, even added a watermark so I knew for sure I was looking at a proxy.
One thing to note, whenever you export a sequence it will use the original file, I guess there’s a default setting that tells it to match frame size of the sequence. Very handy if you are working in 4k all the way. I’ve just started a project that is shot 4k but will be edited 1080, I’ll check my proxies when I open the project in a bit. I don’t know if there’s a setting somewhere, maybe the frame size opotion mentioned earlier in this thread, but I’m after the same solution.
One thing that has tripped me up is the ingest setting. I set things up to copy and create proxy thinking it would use my ecustom ingest settings but it defaulted to one of the presets. Might have been user error
