I'm using Sony Vegas Pro 16 and I'm trying to make my transparent video file I exported on Photoshop look transparent on Vegas. I'm on source alpha and I tried Straight (unmatted) and Premultiplied on the video and it's still showing black background. My file is a MP4 1080p and I even tried .MOV. Tried QuickTime instead of H.264 as my format on render video in PS. Nothing's working. Heres my export render settings on PS
