4K lossless Smart Rendering in Vegas Pro 13

Last summer I remember being told that XAVC-I files were able to be smart rendered. For some reason this morning the search function is bugging out on me.

What I am looking to do is create a master file of my projects I can work with and review for changes. WIth 4K video and adding NeatVid and MBLooks and more high process effects to a track it is tough for me to really see what is going on and many times I am crossing my fingers that all is 100% perfect. Then I spend half a day rendering to XAVC-S and end up with a 30-60 minute video that I review and there might be 2-3 seconds in the entire video that go bad.

What I would like to do is have a file that I can lay over the top, watch easily for mistakes, and if I see something wrong I can just cut that part away and fix a certain clip. Then re-render in the most efficient way without losing quality.

However, when I go to render to XAVC-I again, it still seems to be rendering each and every frame, and not "skipping" that part like a smart render would.

Are there certain setting I need to have to make this possible? Are there other ways to make this possible so I do not lose quality on a 2nd generation render?

Thanks in advance!

Works fine here. Your file on the timeline must be same format as the one you want to render to. I convert all my XAVC-S 4K files in Prepare or Browse to XAVC-I and as long as you don't apply any FX it will smart render.

I am rendering full projects straight to XAVC-I in the hopes it could be a master track that would be easy to fix mistakes. So these are rendered straight from Vegas.

Well, it tried that here too and it works as it should.

I tried from an XAVC-I render straight from VP 13 and it seemed to work. I was using files from VP 12 and I think they are slightly different than the files VP 13 creates as we figured out the other day. Another problem is about half my projects from VP 12 that I try opening in VP 13 crash VP 13 immediately, so I was also trying this as a way to get the bulk of my project to VP 13.

XAVC-I is lossless, correct? I am trying to preserve as much as possible. Even after I get my XAVC-S final files completed, I still run them through Media Encoder to 40Mb/s H.264 4K files to give to clients, as they tend to be much easier to play universally. 100Mb/s XAVC S takes some decent specs to play. So... the less generations of render quality loss, the better.

No it's not. But it does hold extremely well over several generations.

Thanks for the info.

I wish I knew what was in some of these projects that VP 13 does not like. I still have hopes it is a very stable program once I start originating projects from it.

It's usually a missing 3rd party plugin.

I bet it is spitfish. I don't see it in VP 13, but I think all my other plugins are there. I don't have a project in front of me to test at the moment, but I would count on that being the problem. Thanks again.
