Displaying Media During a Digital Cut
The Digital Cut tool lets you output multiple formats at various play rates, all from 24p and 25p
media. When you click the Play Digital Cut button, the system displays the sequence as
described in “Displaying Media While Editing” above, depending on your selection in the
Digital Cut tool.
For more information, see “Selecting Output and Timecode Formats for 23.976p, 24p, and 25p
Projects” on page 1074.
Outputting a Sequence
You can output your sequence at HD by first transcoding it to an HD resolution. You can then
output it by performing a Digital Cut or an export to file. Avid editing systems support output to
tape, write-back to the original device, or export to common industry-standard formats.

Some media formats cannot be output to their native format. Refer to the Avid Editing
Systems—Supported Formats compatibility guide in the Avid Knowledge Base.
(Symphony) Using HD Universal Mastering
Universal Mastering is the ability to generate many different types of output from a single
sequence and project and from the same 24p, 25p, or 23.976p media. HD Universal Mastering
allows 1080p high-definition sequences edited at one frame rate to be played back in real time at
a different frame rate and with audio conversion that matches the video conversion.
HD Universal Mastering applies only to sequences created in a 1080p project format, and the
audio quality is best if you are working with 48 kHz audio.
If you create a sequence in one frame rate (for example, 24 fps), you can then output the
sequence at an alternate frame rate (for example, 25 fps). This modifies the duration of the
sequence to roughly 96% of its original length.
HD Universal Mastering preserves synchronization with the converted video by remastering
audio at a different sample rate to generate replacement audio tracks from previously
mixed-down audio clips. Once replacement audio tracks have been generated, you can edit them
into a new sequence, or edit them into the original sequence as alternative tracks, and then use
the Digital Cut tool to output the sequence.
With Nitris DX, when you downconvert a 1080p/24 project to NTSC, there is no need to
resample the audio.
