What Quality are Nested Veggies?

Grazie wrote on 9/29/2006, 7:23 AM


I want to know what quality setting the Nested Veg proxy is created in? Preview? Good? or what? I would have thought they would be a t least at a quality that would allow nigh on optimum frame rate? No?

I'm asking 'cos at present I'm getting low framerate on a nested Veg, compared to the Parent Veg of the same media. Hey, I guess even if I/we did know I'm NOT in a position to change it - yeah?

TIA

It's realtime render, Grazie, that's why it can be slow. If you have effects in the nested veg, it has to render that before it can render/merge with the higher level tracks.

Now, if you were to do an uncompressed pre-render on the nesting, I think people have found that it keeps the association up the chain.

there was a recent topic on just this a few weeks ago.

Bottom line, there is some overhead using nesting. I do a lot of RAM renders to work with the footage.

Edited: Re. Quality, I haven't tested, but I would assume the quality would be the nested veg project quality setting. So if the nested project was Draft, setting the upper project to Best would still make it look crappy. I always use Best, so there is nothing missed in the final output. I'm sure you would get better system response from Good.

Grazie, I just tested, and it appears that the Project Good/Best settings have no effect when it is nested. I placed a video in a project set to "Draft", and it looked horrible.

Started a new project with the same video on timeline 1, timeline 2 had the above veg. I toggled back and forth between the two at Best, and there was no difference on the secondary monitor.

I guess a better test with Best/Good compare would be to use identical text media in the vegs, where if the project were set at HDV, make the text media set to DV so it has to resize. Then compare a Draft nested veg in a Best main veg, and toggle back and forth.

In my experience, ALL parameters in a nested veg are applied regardless of hosting veg parameters.

Originally it's vewing quality was determined by its project setting. Folks complained about that though, so now it's viewing quality is determined the host project setting. When it comes to rendering, I don't know at all what determines the quality in that situation.

Perhaps Sony would chime in?

Dave,
Yes, it appears that the nested veg's project setting has no effect. I put Sony Text at 320x240 into an HDV size project at Draft project quality. It looked exactly the same on the main veg's timeline as the Best sample text.

Strange, I saw a "Last Post" by Forum Admin at 1:46 pm, but when you selected the topic, it's not showing up???
