When we use a camera feed as a picture in picture layer it sometimes in unclear visibly that that image is actually separate from the full screen behind it. I’d like to see a way to attach a simple line frame (in color if possible) to just that picture in picture layer. Such a frame needs to resize and/or move along with the layer.
We’ll consider your suggestion. In the meantime, if you need to see where the border is, click on the PiP layer to highlight it. You’ll see a green frame that will separate it from the main layer.
Adding custom borders around video frames would be a nice feature. Please consider adding in the future?
