Importing and Exporting AAF Files
You can use AAF (Advanced Authoring Format) files to exchange projects between applications. For
example, if your postproduction facility uses a tool other than Vegas Pro, you could provide your project as
an AAF file.
Creating an AAF file
If you intend to export your project as an AAF file, please note the following usage guidelines and plan your
project accordingly:
n Audio and video cuts are preserved.
n Track-based audio gain and panning are preserved when saving or importing AAF files.
Select the AAF Export - Use clip-based audio envelope check box on the General tab of the
Preferences dialog if you want to combine track and event gain envelopes and save them as clip-
based gain envelopes in the AAF file. When the check box is cleared, track envelopes are saved as
track envelopes, and event envelopes are saved as clip envelopes. For more information, see
"Preferences - General Tab" on page 576.
When exchanging AAF with another application, refer to its documentation to determine whether
audio gain and panning changes are supported.
n Muted audio tracks are not included in the AAF file.
n When you import an AAF file, the track- and clip-based gain envelopes are combined and imported
as track envelopes.
n Audio and video effects are ignored.
n All video transitions are exported as AAF Video Dissolve transitions.
n All audio crossfades are exported as AAF Mono Audio Dissolve transitions.
n Time-stretched video is exported using the AAF "Video Speed Control" effect.
n Time-stretched audio is not supported: audio events that are time stretched will play at their original
speed, and time is added to the track to represent the stretched duration; audio events that are time
compressed will play at the original speed, but the event is trimmed to match the compressed event
length.
n Any track that has mono and stereo audio will be ignored; the AAF format does not allow mono and
stereo audio on a single track.
n Still images will be exported as 1,080,000 frames (the AAF specification does not allow media with
a length and frame rate of 0).
n Track order in your exported AAF will not match your Vegas Pro project: in the Vegas Pro track
model, the first track represents the foreground; in the AAF specification, the first track represents
the background.
