Interlacing issue in Vegas Pro 13

[John Rofrano]

[Martin Stanesby] “if it’s not about deinterlacing the footage…why does Vegas call this option ‘deinterlace’?”

Sorry if I didn’t explain it clearly. It absolutely is about deinterlacng the footage but not about you “wanting” the footage to be deinteraced but rather Vegas Pro “needing” the footage to be deinterlaced to perform some operations. Confusing I know.

[Martin Stanesby] “I would h ae thought Vegas would default this option if interlaced footage MUST be deinterlaced….why have the option for none?? “

It’s an option because you might want to use a 3rd part deinterlacer like the one that comes with Boris Continuum Complete. So Sony gives you the option of using theirs or providing your own but you need to provide your own deinterlacer if your footage is interlaced and you set this to None. They forget to warn you about that one and allow you to “shoot yourself in the foot”.

Yes, many broadcasters still use interlaced formats. So the “jaggies” live on. Sorry, I don’t have a good answer for you.
I have usually selected “blend fields.”

Here is an interesting article. https://www.cnet.com/how-to/1080i-and-1080p-are-the-same-resolution/

Hi John,
So even though Vegas needs to deinterlace…….will the project still be interlaced when rendered? I’m presuming so as this is the point to shooting interlaced and having an interlaced project running. Otherwise I’d be really confused…..

Thanks
Martin

[Martin Stanesby] “So even though Vegas needs to deinterlace…….will the project still be interlaced when rendered?”

The Project will retain the properties of the project settings. So if you set up the project to be interlaced, Vegas will keep everything interlaced. How you render the project is completely a separate thing. You can render it as interlaced or progressive. But setting the project properties to be interlaced and selecting an appropriate deinterlace method (like Blend Fields) will keep everything interlaced throughout the editing process.

Yes, exactly!
