With a few thousand videos spread across multiple drives and arrays, 
performing a scan of the Video Library only takes me a couple seconds.  
Any new content added needs to be hashed, but you're talking about 
reading 64KB from the front and back of a file.  Not something time 
intensive for even dozens of new files.  If you have the batch metadata 
grabber enabled, that can take some time churning through the new 
content, but that is run in the background and is going to turn up empty 
on home videos anyway.

If your scans are taking several minutes to run each time, there is 
something misconfigured on your system.  Is this content local to one of 
your backends, or on a remote network share?  There is a known issue 
where CIFS shares, and especially deeply nested ones, take an 
inordinately long time to scan.
