<p>I have just edited a 4 hours video down to an hour, and now want to make that 1-hour long video into parts of 12-18 min. How do I do that without the need to render the 1-hour video first?</p>

I have just edited a 4 hours video down to an hour, and now want to make that 1-hour long video into parts of 12-18 min. How do I do that without the need to render the 1-hour video first?

Also, is there a way that I can take my microphone recording from video and put it into Adobe Audition to remove white noise and background noise?
