HOW TO FIND OFFLINE CLIPS IN THE TIMELINE

In the timeline open the Fast Menu and go to Clip Color and select Offline and it's show me whatever clips are offline in Red so I'll know which clips need to be re-digitized or I may have to mount another drive because the source material is missing.

FINDING CLIPS OR BINS IN ANOTHER DRIVE THAT MAY BE OFFLINE
•  In the Timeline Fast Menu, choose Show Clips that are offline
•  Make a New Bin (call it Offline Clips)
•  In the Timeline, find the clips that are offline
•  Drag Subclip into Bin
•  Highlight the clips
•  Set Bin Display
•  Highlight all and OK

FINDING CLIPS THAT MAY BE HIDDEN

This may be because multiple editors are sharing media for multiple projects. I may want to open a Bin from someone else's project to find a clip. To do this, go to the Fast Menu in my Project Settings Window and make sure none of my Bins are selected and choose Open Bin and the Finder Window will open and I can navigate to another project folder and then I can double-click on a Bin and it'll open the Bin in my project and I can use the clips as long as they are the same frame rate. Just don't delete someone else's master clips for media. I need to make a copy of their clip(s) and bring it into my bin.

TO FIND WHERE A CLIP IS LIVING ON THE COMPUTER
Highlight a clip in the Bin and choose File – Reveal File and it’ll go outside the Avid and open the computer folder that it’s in.

MEDIA TOOL- this is an amazing way to find stuff and I can sort by different things
I can search by drive. If I’m low on memory, I can erase Precomputes (render files) for stuff I’m not using
