If you import a file and it appears horizontally or vertically distorted (stretched), its pixel aspect ratio may not be
interpreted correctly. Change the pixel aspect ratio for the file if necessary. Adobe Premiere Pro continuously
rasterizes EPS images, so you can scale these files without pixelation.
•
To import clips, choose File > Import. Locate and select a file, or hold down Control and select multiple files. Click
Open.
•
To import a recently imported clip, choose File > Import Recent File > [file name] . (The file name may not appear
if Adobe Premiere Pro preferences have been reset.)
•
To import a folder of clips, choose File > Import. Locate and select the folder, and then click Import Folder. The
folder imports as a new bin in the Project panel with the folder’s contents.
You can also import files and folders by dragging them from Windows Explorer into the Project panel.

Importing digital audio
You can import digital audio clips stored as audio files or tracks in video files. Digital audio is stored on computer
hard disks, audio CDs, or digital audio tape (DAT) as binary data readable by computers. To keep quality as high as
possible, transfer digital audio files to your computer via digital connections. Avoid digitizing the analog outputs
from your audio sources through your sound card.
For maximum editing performance, Adobe Premiere Pro conforms each imported audio channel to 32-bit
floating-point data at the project’s sample rate. All imported audio is conformed, even audio tracks in video files.
Note:
If you want to capture an audio-only file from a digital video source, choose Audio from the Capture pop-up menu
in the Logging pane of the Capture panel.
You can use CD audio (CDA) files in a project, but before you can import them into Adobe Premiere Pro, you need
to convert them to a supported file format, such as WAV. You can convert CDA files using an audio application such
as Adobe Audition
®
.
Note:
Make sure that you own the copyrights or have licensed the copyrights to any CD tracks you use.

Using compressed audio formats
Music stored in formats such as MP3 and WMA are compressed using a method that removes some of the original
audio quality. To play back compressed audio, Adobe Premiere Pro must decompress the file and may need to
resample it to match your output settings. These conversions are likely to degrade audio quality. For this reason, use
an uncompressed or CD audio version of the audio clip whenever possible.
Using audio from Adobe Audition
You can use Adobe Audition to perform advanced audio editing. If you export the audio from Adobe Audition to an
audio file format compatible with Adobe Premiere Pro, you can import the audio into your Adobe Premiere Pro
projects. If you select the Project Linking option as you export audio from Adobe Audition, you can choose Edit >
Edit Original in Adobe Premiere Pro to open an audio clip’s Adobe Audition project directly from within Adobe
Premiere Pro.
