Will I lose any quality by exporting 25fps clips to 50fps?

Hi,

I’m trying to create clips from a long 50fps video - some I’m exporting just as 50fps, and others I’m slowing down to 25fps and playing at half speed.

The end goal is to have a large repository of clips which I can import into a 25fps project.

Should I be creating the 25fps slowed down clips in their own project, or doesn’t it matter?

Thanks
