IIRC... Temporarily set project settings to progressive, run analysis, set back to interlaced. Or something like that :) I posted about this before so you can search the forum. (No time at the moment to confirm steps.)
You can leave project settings on progressive and render with a interlaced template. It is just important that you switch projectsettings to progressive before letting Mercalli 4 analyze your events.

Thank You Kinvermark and 3POINT. Worked Here!
I also realized that if you apply Mercalli 4 using Vegasaur Batch Stabilization it also works and you do not even have to configure the project to progressive. Thank you for your help!
