Catalina Users: Exporting from Avid Media Composer 2020.2 beta

It has come to our attention that the 2020.2 beta release of Avid Media Composer for Mac OS Catalina users does not support standard Quicktime Exports. This guide provides a work-around and is ONLY intended for students working on Catalina and Media Composer version 2020.2.

Alternate Export Setting

Use the typical Output/Export to File

Choose the 'untitled' preset in the 'export as...' window (we're changing this anyway). Then hit options.

In the 'Export Settings' window, next to 'export as" choose "MXF OP1a"

Under Video Compression select DNxHD 115

Under Audio select 4800kHz, 16, stereo (unless you've mixed for 5.1 surround)

Click Save

Name your file and give it a location. (Notice the new .mxf extension)

This will give you an uncompressed MXF file which can be played by most programs - except Quicktime. 

 

VLC Player is a great free video playing application that can handle more formats than Quicktime. This program should be able to play your MXF file smoothly. Here's the link if you need to download it: https://www.videolan.org/vlc/index.html

 

Transcoding MXF to Quicktime or H.264

 

If you are unable to download VLC, need a compressed file, or you are required to submit a Quicktime format file, you can transcode one using Adobe Media Encoder. This program is automatically installed if you have Premiere Pro on your computer. 

 

Open Adobe Media Encoder from Applications

Add your file to the queue by dragging it into the window on the right.

Select a preset by clicking the dropdown arrow. H.264 is a great preset if you’re playing in quicktime or uploading to the web.

Or you can customize your settings further by clicking directly on the blue text to reveal the familiar Premiere export settings window

Be sure to rename your file so you don’t overwrite the original. Click on the blue text under "Output File"

Using the codec to organize your exports is a nice organizational tip. Choose the location for your export.
