How to Create Audio Mixdowns for 8 channel MXF OP1a Export

Creating audio mixdowns like this can be tricky, because you need certain tracks (like VO or SOTS) center-panned for the full mix but assigned to specific channels for the split. Here’s how you can achieve this:

Step 1: Set Up a Multichannel Sequence

1. Go to File > New > Sequence.
2. In the Tracks tab, set the following:
   • Audio Mix: Multichannel
   • Number of Channels: 8
3. In the track list below, add 6 audio tracks and set each track’s Track Type to Adaptive.
   

Step 2: Assign Audio Outputs

Assign the output channels for each track:

• For the VO track:
  • Click the Output Assignments button.
  • In the first column, check Ch. 1, 2, and 5 to send audio to these channels in the output
• For Camera Mic/SOTS, Natural Sounds, and SFX tracks:
  • Follow the same approach as above but assign channels as follows:
    • Camera Mic/SOTS: Ch. 1, 2, and 4
    • Natural Sounds: Ch. 1, 2, and 3
    • SFX: Ch. 1, 2, and 6
• For Music tracks:
  • Assign to Ch. 1 and 7 in the first column and Ch. 2 and 8 in the second column.
