ISO performance tips for editing 4K video
I recently made a major upgrade to my camera gear. I bought a Lumix G9. Previously, I'd been doing my videos on an ancient Canon Vixia HFS-100. Not only do I now have the option of shooting 4K, but the upgrade opens up a whole Pandora's box of possibilities with color profiles and grading.
Here's the problem though: my trusty old iMac*, which edits 1080 footage just fine, slows to a crawl when I try to edit 4K footage in Hitfilm Pro. The Viewer just hiccups and glitches and herks and jerks. I can put clips on the timeline, export the series, and look at it, but I can't really tell what I'm doing with any careful editing.
Buying a new computer right now is not an option; I over-extended myself financially with the shooting gear.
Are there any tricks to make this work, or should I stick to 1080 for now?
I've looked through the archives a bit trying to find answers to my question, but haven't found much that's applicable.
