Yes we can on our new, by request, package called Siberian

On the Pom and Eskimo plans, we can only render final videos in 1080p. If you’ve filmed 4k footage, we can edit it if you can provide us with proxy files or we can do a conversion.

Most of our customers submit proxy files so it’s easier to upload, download, and work with their editor. In those cases, we can also submit the Premiere Project Files back to you so you can link all the final videos.
