Resolve 12b3; fine PC but slow with 4k and hundreds of mask keyframes ???
on Aug 31, 2015 at 7:36:03 pm

This a fine PC, 6-core, latest Asus mb, SSD for OS, 32GB DDR4 ram, AMD R9-280 card; about 70GB virtual ram setting. Terabytes of storage as needed.

BUT it is slowing down, almost always showing full ram utilization, even after a save with no operations pending. Takes about 30 seconds to save even with no changes. (FWIW, Premiere doesn't even offer the Save option if there are no changes.) With changes, takes several minutes to save.

Here is the workload: 4k (UHD) ProRes 422 HQ source, with about a dozen color nodes to mask simple face against background and hundreds of keyframes to follow a highlight mask. New keyframe every few seconds.

Is this workload itself the issue??? Or, some configuration options that need attention???

Moving or re-positioning the mask quickly slows down until it becomes unworkable.

Must be missing something in configuration??? Asking too much???

I have tried cutting the long original take into smaller segments. No joy.

Must be a fix for such a fine and very mature program.

Thanks,
Mike
