Highest quality to export a film?

[Walter Soyka]

[nige morgan] “Using adobe premiere pro cs5.5. Film is 83 minutes. 1080 HD. Want to have the film in the highest quality for back up / master, what would be the best options for this? “

Practically speaking, a mastering format like Apple ProRes or Avid DNxHD are good choices. They are compressed, but very lightly — the result is usually visually indistinguishable from the original. MXF Op1A AVC-Intra Class100 might be a good choice, too.

As always, though, the best answer to your question depends what you mean by “best.” It also depends on a bit on how it was shot, graded, VFX, etc.

A 16-bit TIFF sequence would be perfectly lossless, but huge and unwieldy. A 10b RGB uncompressed movie would also be very large and high quality. A 10b YUV movie may be a good option if the chroma subsampling isn’t a problem in your workflow.

The Avid DNxHD codec you downloaded is a QuickTime codec. You won’t be able to view DNxHD-encoded movies in Media Player, but you could view them in the QuickTime Player (or VLC, as you note).

With respect to the lines you are seeing, you should make sure that the DNxHD codec settings (there’s a button for this in the video tab under Video Format when you export) matches your sequence settings.

Ok it’ll try doing that, even on mpeg preview it does that line thing, thought it could be because its progressive and it might be set up as interlace.
