Premiere Elements 2018 (Mac, Mojave) won't accept .mov files

Hi,

I have videos done with my iPhone, which produces .mov files. But I can't import them into Premiere Elements 2018 to edit.

If others have this problem have you found a workaround? Using a third-party converter to render the files in another video format?

This seems a real flaw in an otherwise fine program, not to recognize a very common file format.

Any help will be appreciated! Lots of great videos of 4 year-olds await.

Thanks.

Rachel
