Avid Guide for AMA Workﬂow

QuickTime

What happens if….I try and link to a QuickTime reference movie?

This is supported, but keep in mind these limitations:

• You cannot make a QuickTime reference ﬁle from your Avid editing software if your timeline contains AMA

clips within it

• You cannot create a QuickTime reference from your Avid editing software if your timeline contains LongGOP

media, such as XDCAM clips

Working with ProRes Movies

Apple ProRes is a popular QuickTime codec that permits the exchange of media between many devices

that use this codec, including Final Cut Pro. Media Composer, Symphony, and NewsCutter all support this

codec natively, although slightly differently on a Mac compared to a PC. These differences are due to licensing

considerations between the two platforms.

The chart below shows which Avid editing functions are supported on Mac- and Windows-based computers

when working directly with ProRes ﬁles. For example, TRANSCODE means can you transcode into a ProRes

codec—not whether ProRes AMA-linked media can be transcoded to other formats.

EXPORT

Same As Source yes*

* ProRes export on a PC is possible when performing a “Same as Source” export to a .mov ﬁle. However, this will

not work with sequences that contain mixed formats—meaning, media other than ProRes. AAF- or MXF-wrapped

exports as ProRes are not supported.

Ingesting Apple ProRes

AMA linking to a ProRes ﬁle is the same as with any other QuickTime ﬁle. You can link to and edit the ﬁle as

you normally would. You can also transcode it to create a copy using a different codec into Avid storage.

But what if you wanted it to stay in its ProRes format after you ingest it? Here are a few ways of getting ProRes

media into your Avid storage (local or server) as ProRes ﬁles, with the fastest speed and best possible quality.
