previewing 16:9 clips in a project with vertical timeline

The final video must be in vertical aspect ratio, so the timeline is created in 9:16.
But the source clips are in horizontal 16:9. How do I preview them properly? Currently, they are cut out to match vertical resolution, even in the Source Viewer for some reason.

You can use guides for preview of where the crop will happen. They are above the viewer.
You can set up differnt timeline format than output format in the timeline settings. So you can keep horizontal clips while working in vertical format and than just position them where you need to. That is the common workflow. If you don't want to see the crop until the end you can use the guides and just change output sizing at the end in the same or duplicate timeline, depending on how you want to work. If you have studio also consider using smart reframe. Which can make it easier to reframe Or you can use regular position controls. And keep an eye on mismatch resolution settings since they will be key to how clips of differnt aspect ratio than the output resolution or working resolution of the timeline, interact with each other.

The Source and Timeline Viewers are currently locked with regard to aspect ratio. Whatever you set the Timeline to will hold true for the Source Viewer as well. Currently, there is no way to separate them.

Kruno's idea is to edit in the normal 16:9 aspect and then switch to Vertical afterwards. The Social Media Guides can help with framing.

Yes. Something like this.
