I was making a video and then I realized it was in 480p. I went to Sony Vegas to render it in 1080p quality so I could upload it. Does it make the video in 1080p quality? I didn't render yet because I wasn't sure.
No; the video quality will still be the same as the original 480p recording.
Additions you've made in Vegas would be 1080p-quality, though.
Do you know anything that can make my videos from 480p into 720p or 1080p? I really need it because of my videos I'm making and people keep telling me that not much people watch video in 480p anymore.
