PAL 601 resolutions have an odd (upper field first) ordering. NTSC 601/DV resolutions have an even (lower field first) ordering. This setting defines how the source material is interlaced.Īn odd, or upper-field ordering uses the first line of each frame for field one.Īn even, or lower-field ordering uses the first line of each frame for field two. This is because the Avid QuickTime codec inverts the alpha during the movie's creation, saving time on import into your editing applications while not significantly adding to the creation time in a third-party program. When alpha is imported from a non-Avid QuickTime codec, select Alpha > Invert Existing. Use Existing in the Import Settings dialog box.
