Only those VTRs with a timing that matches the video timing are available for use in the Archiving menu. When you want to archive or restore clips of multiple resolutions in one project, enable the VTR lines in the VTR keyword of the configuration file for all the resolutions you use on the project. This way, each time you change the video timing for archiving, the compatible VTRs are available in the Archiving menu.
When you archive to a VTR, only clips with a resolution compatible with the selected VTR device are archived. If you select a set of clips of differing resolutions, only the compatible clips are archived. Clips that are not compatible are greyed out in the library.
