Hey,

I would just like to follow up on the above, since I too, having just migrated from FCP, am accustomed to editing in lower res and swap out with full quality footage at final stages – and have as a result spent ages trying to figure out how to avoid starting my multiclip edit from square one.

Here is a more detailed description of the steps, based on the comment above, to save whoever else is looking for a solution a whole lot of time that could be better spent….

so,

To replace multiclip, open up project, relink media to new full quality footage, you will notice that the footage looks ‘zoomed in’/cropped to fit frame size. This is fine. Save and close. Now, duplicate the project to keep a backup of the file (.prproj) then open the original project using textedit.app, and find and replace all instances of your old dimensions, to the desired ones as follows:

<FrameRect>0,0,1280,720</FrameRect>

to

<FrameRect>0,0,1920,1080</FrameRect>

**in my example I am changing from 1280×720 to 1920×1080

Done.

Quickest and easiest solution I found. And most importantly, it works.

Good luck to all
