I'm having an issue where any clips I link (using the source browser) at a different frame rate from my project are set as "Blended Interpolated" instead of "Both Fields" in the motion effect editor.  I'd like to set the default behavior to the opposite since all my footage is all progressive.

Example:

I shot footage at 59.94 and am editing in 23.976 1920x1080 HD.  I linked in the clips using source browser and all the footage shows up as interlaced (see example below).  

If I promote the clip in the Motion Effect editor, I can change it from "Blended Interpolated" to "Both Fields" which fixes the problem, but I have thousands of clips and I don't want to have to promote each clip and make this change several ahundred times.

Is there a way to set the default way clips of different frame rates are handled?

NOTE the blond lady on the right and her wine glass...

Here is before (top image) set by defualt to "Blended Interpolated":

And here it is after promoting the clip in the Motion Effect Editor to "Both Fields":

What are the project settings (for the timeline), and what is the format for the linked clips? For example, is this a 24P timeline and 30P clips, etc.? I'd like to try and reproduce this using MC 12.x.

It's an HD 1080p 23.976 fps project in YCbCr color space.  The clips were shot in 59.94 progressive.  The clips were filmed on a Nikon Z6 with an AVC codec.  

The source browser shows the Plug-in as: Avid Generic Plug-In --  and the codec as AVC Long-GOP High (HD1080p) when linking it.

Do you need a sample clip to try to recreate?

Also, I'm using the most up to date Media Composer version.  When I made the post, my profile had a very old set of specs.  I'm using MC version 2019.12

Look under the Render settings.  There is a option for that.  Sadly, it does not change clips already imported.  You might have to start over.....

I've got render motion effects set to Both Fields. I probably set it that way a long time ago. Apparently the default is blended interpolated. Good call Jef.

I think that was the setting I was looking for!  Thank you!  I'll give it a try on my next project to see if the problem goes away when I set it before linking/transcoding.
