This seems to be a persistent problem since previous versions. Please fix.
Steps to reproduce:
In my case:
1. Create a project with about 40 audio files down the timeline
2. Edit stills on the video tracks to sync with the audio files
3. Select a short section to export (aroud 30 sec. worth)
4. Send to Media Encoder
Result: ...
Media encoder has to process 40 audio files before it renders the video. Rendering video takes 2 seconds. It takes about 30 seconds to process all the audio.
Expected: ...
For it to take 10 seconds to render the whole thing. Only one audio file was selected to export.
