Sequence Audio Format
Your sequence has an audio format, specified in the Audio Mixer. You indicate your sequence's audio format using the Sequence Mix Format button and you indicate your hardware output from the Mix Mode Selection button.
| The drop down menu on the left is the Sequence Mix Format button. |  | |||||||||||||||||||||
| Your sequence can be Stereo, 5.1, or 7.1. You should choose 5.1 or else you would not be reading this wiki. |  | |||||||||||||||||||||
The drop down menu on the right is the Mix Mode Select button. Audio Mix Mode and Monitoring Options To hear a surround sound mix, you need surround sound hardware. If you don't have the hardware, the mix options will be grayed out. The hardware connects to the speakers through which your surround sound mix will play. Media Composer can use a third-party sound hardware, or you can use the Avid Artist I DNxIO hardware, which has an HDMI connector capable of transmitting surround sound to a receiver. The mix mode sets your speaker layout so Media Composer sends the correct signals to the associated outputs on your hardware. The mix mode addresses the following questions : • Do you have two, four , six, or eight speakers? • How are your surround sound speakers connected to your hardware? • How does a stereo sequence play back when you have 7.1 surround speakers? • How does a 5.1 sequence play back when you only have two speakers? (This is probably you) |  | |||||||||||||||||||||
When your sequence mix format is set to either 5.1 or 7.1, you will see that the Master output switches to display 6 or 8 audio meters. The order that these meters show the different output channels is set in the Audio Settings (found under the Settings tab of the Project Window). Since Media Composer v8.6 you can choose to monitor in ProTools or SMPTE order. We recommend SMPTE order (L, R, C, LFE, Ls, Rs) |  | |||||||||||||||||||||

| Now that you're familiar with the audio settings, lets export a 5.1 QuickTime movie. | ||||||||||||||||||||||

Simply highlight any other export setting and press Command + D. Don't know how to rename an export setting? Simply click on it's name and type.

3. Configure it as shown: Video Format 1920x1080 Size to Fit Scale from Legal to Full Range Audio Format 5.1 Movie Settings Video Compression Type: Avid DNxHD Codec Color Levels: RGB Levels Resolutions: 1080p/23.976 DNxHD 115 8-bit Audio Format: Linear PCM Channels 5.1 (L R C LFE Ls Rs) Rate: 48.000 Quality: Best Sample size: 24 Little Endian |      | |||||||||||||||||||||

5. Now in the bin, select the sequence, right-dick and choose OUTPUT> EXPORT TO FILE . |  | |||||||||||||||||||||
6. Choose the Export setting you just created and a destination (the desktop for example). |  | |||||||||||||||||||||
7. Perform the export. You have now created a surround movie as a Quick Time format. If you play it, you will see (or perhaps hear) surround, but how do you know it is a surround movie? Well the answer is to re-import it. | ||||||||||||||||||||||
TO RE-IMPORT Link to the file you just exported. |  | |||||||||||||||||||||
