I am having this big problem. I rendered a 15 second video in Vegas, but it is 4:9, and the video player is 4:9 as well. The platform I am trying to upload it on does not support 4:9 videos, and I do not want to stretch it. I want to video to be 16:9, but with black bars on the sides so the video stays the same aspect ratio. Is there any way I could do this?
