When a Library visual needs to leave Brandiseer for print or a client pack, you should not have to bounce through a third tool just to get a PDF at the right size. Library PDF export turns stills into PDFs that keep the same footprint you generated, from the places you already browse assets.
One honest limit up front: video and SVG are out of scope for this export. Stills in Library are the path. That keeps the PDF path predictable for print and review workflows.
Grab a still from Library, export PDF, and check the size matches what you generated. If it looks right on screen, the PDF should carry that same footprint out the door.
