Generally, archiving to data tape or filesystem are easier ways for archiving mixed-resolution projects, as clips of any resolution can be archived on the same medium. It is also possible to archive multiple-resolution projects to a VTR. This operation, however, may require multiple tapes with different timing corresponding to each segment resolution. Alternatively, you can use the Unlink tool to unlink media from clips of any resolution, archive unlinked clips, and then relink the media at restore time. See Unlinking Media from Clips in the Clip Library.
