I don't know what I did wrong. The previews were starting to go unbearably slow, so decided to try out proxy clips. Setup according to the instructions, but now the previews are still in HD, but when I renter it renders the project in the proxy clip resolutions. I'm sure I screwed up somewhere but can't seem to fix it. I have the yellow P in the thumbnail on the left.

I'm using the Windows 10 version on an older I7.

Never mind, was just my render settings. It still doesn't seem to be using the proxy clips for the timeline preview though. Is there something else I need to turn on other than proxy clips in the settings?
