Allow for multicam proxying for better UX
As a user with a machine that is not built for intensive video editing, I'm experiencing significantly slow UI response time when working with multicam, to the point where it's not usable. However, I'd still like to be able to use the multicam feature and believe it is possible by creating proxy file(s) for multicam previews or otherwise having PP pre-processing them for me for a smooth user experience. This will save the need for PP to resize each frame from each source in realtime.
So i'd like PP to either:
- create a separate resized preview proxy for each of the sources in the array
- or, if that's not going to help, at least to create one single proxy file of the entire MC array
- integrate the proxied preview into the multicam feature so that the rest of the workflow is the same.
- in case there are changes in the underlying videos, proxies should be partly or fully purged and re-built.
Working on a Macbook Pro Retina Display mid 2014, i7 2.5Ghz quad-core CPU, 16 GB RAM, internal SSD, GPU NVidia Geforce GT-750 with 2GB memory, Premiere Pro 13.1, 10-12 ProRes 442 Proxy source clips.
In the attached image I have created myself a workaround, by exporting a "mock multicam" preview into a file and placing that file as one of the clips. This worked around the performance issue. I can monitor and edit all clips together, without latency and with a smooth workflow, but not using true multicam features of course.
If PP could do the same in the real multicam feature, it would allow for users like me to work with it without needing to upgrade their hardware.
