user5546: I have edited a 640 x 360 clip into a sequence in Premiere CC. The sequence includes changes to the scale for different shots. Now I want to replace the 640 x 360 clip with a 1920 x 1080 version of the same clip. When I do that, the apparent scale increases by a factor of 3; a shot in the sequence that should have a scale of 100% now APPEARS to be at 300%.

I'm sure it's because the new clip is so much bigger.  But is there a workaround that lets me keep the APPARENT zoom level of the original, tiny clip?  That is, can I make this new clip LOOK like its scale is 100% when the original sequence had the scale set to 100%? Can they look the same?
BTW, I know I can set the scale of each shot manually in the timeline.  But I may have 50 or more edits so I'm looking for a global solution.  I was hoping there was like a "master scale" setting for clips in the media browser, but I didn't find one.

user2836: After the fact, no I don't.  If you know before the fact in the future though, you can put the source on a timeline by itself and apply the scale there and make all the clips point at that timeline.  This is the same technique I use in After Effects whenever I am working with animating a base layer that I know I am going to need to change.  That way I can make a simple change to the source clip and not have it impact the overall sequence.

user5546: Premiere CC lets you adjust the dimensions of the sequence.  It will keep the same scale changes (zoom in & out) in the timeline.  So increase the dimensions of the sequence to accommodate the larger clip, then replace the small clip with the large clip.
This isn't a perfect solution. For example, titles will appear very small, and will not be in the right positions, relative to the new larger clip. I'm pretty sure that any position changes of the clip will be reduced as well, since they're in pixels rather than percentages of the width/height of the sequence.
