This appears to be a company decision to not support that format at this time. The vertical 9:16 setting is a fairly recent addition, for example. Both of these threads offer different approaches to making 1:1 videos from the PD side.

If you're making a FB ad, you can make the video in PD with the content in the central square (which may actually be easier with the 4:3 format) and use FB's cropping tool under Manage Ads to crop it it 1:1 as explained on this page. This would seem like the simplest way to go.

Hi Stephane99 -

In a world of Instagram, Facebook, Twitter, IGTV & mobile devices, I guess it is an odd decision NOT to incorporate 1:1 apect ratio into an NLE.

As has been mentioned in other posts, PDR cannot produce square videos at this time. Once you've built your video in PDR, there quite a few easy ways to get it cropped to 1:1.

One of the simplest (free) ways is to use VLC Player to convert/save the video using the method shown in this tutorial. For converting a 16:9 - 1920x1080 - video to 1:1 - 1080x1080 - this involves cropping 420px from left & right. Once you've set that up in VLC Player's preferences, it's permanently available for other similar tasks.

Here's a little 16:9 video made in PDR17. Here's the cropped 1:1 version made in VLC Player & the same thing posted on Facebook.

As a guide, when making the video in PDR, you can use a temporary overlay like the one attached so you know what space you're working with.

Cheers - Tony
