You may have noticed that when you open up EDL Manager, one of the options is to display Comments. The Comments the EDL Manager is referring to are specific to the clips in the timeline, not the masterclips. Here's how you apply comments to your clips.

1. Highlight a clip in your sequence.
2. click the sequence title in the upper-right corner of your monitor window
3. Select Add Comments from the drop down window and add your comment in the dialogue box

Now when you create your EDL, any comments made to your clips will show up. You can put useful information like order codes for stock footage, clip descriptions or any other notes about that specific clip.

It's important to note that these comments are specific to that clip in that sequence and won't show up in other timelines where that source clip is used.
