Pls a hypothetical but equally important question (at least to me).
If a premiere 2.0 project with footage captured and initially edited at 1980x1080 using ProspectHD was latter reopened using Apect HD at 1440x1080, what are the issues one should expect.
Will realtime editing still be possible.
Thanks.

Aspect HD will decode Prospect HD, but only to 8-bit precision. Although Aspect HD is limited 1440x1080 the 1920x1080 will play.
