Re: DG System Back Level

MPEG2 is normaly 720x480. In my template I have setting that crops 720x486 to that size.

720x512 is a setting that Pathfire uses. You "crop out" sort of like creating black letter box during encoding. You're not resizing the video image at all. That creates space in the verticle interval for Sigma encoding for VNR use tracking. You don't need to do that for TV spot distribution since you just need proof/certifcation that they aired.

It's important to note that for broadcast you're not changing pixel aspect ratio either (compared to changing not square to square for computer/web use).
