Unable to publish to mp4
Hello,
I'm having trouble publishing my Captivate 9 project (mac, el capitan) as an mp4.
When I attempt to publish the video, I see the screen below:

When I click "Yes", none of the settings are adjusted, and the same screen pops up when I try to publish. I just published a similar, larger file (4MB versus 2.4MB) with these exact settings and had no trouble. Additionally, I checked my activity monitor on my mac, and when attempting to publish, 98% of my cpu capacity was idle.
Here are the settings that it is currently attempting to publish at:

Any suggestions on how to publish this file?
