Sample Rate Conversion Options
These settings allow you to convert the sample rate of your Pro Tools session during export to AAF or OMF by sample-rate converting each audio file, and adjusting the edits in the resulting AAF or OMF file to compensate for this change.

You might want to change the sample rate of a session if you are exporting to a system or are at a stage in the process that requires a different sample rate.

For example, your session contains audio media at 29.97 fps (NTSC video) at 48 kHz, while the film composer to whom you are exporting your session requires audio media at 24 fps (film speed) at 48 kHz. To convert all the audio files and edits to play back at 24 fps (film speed) at 48 kHz, you would set the Source Audio Sample Rate setting to 48,048 (a pull up rate of 0.1%) and the Destination Audio Sample Rate to 48,000. These settings tell Pro Tools that you want to fit 48,048 of the original video speed samples into 48,000 of the new film speed samples. With these settings, you sample-rate convert the video material to film speed.
This setting allows you to specify the sample rate of the material you are working with in Pro Tools, independent of the session’s sample rate settings.
This setting allows you to specify the sample rate for audio files after the AAF or OMF translation.
If this setting differs from the Source Audio Sample Rate setting, audio is sample-rate converted digitally to the Destination Audio Sample Rate.
These settings correspond to Pro Tools sample rate conversion settings. It is not recommended that you use the Low (Fastest) setting. The Tweak Head (Slowest) setting provides the highest quality sample rate conversion.
