Split screen render?

[Graham Bernard]

[Paul Gregory] “I have never had much success with using the split screen preview to see before/after effects of filers that I would like to try out.”

What exactly are you doing? You’re “solutions” are way way over the top for something that should just be working. As I say, what are you doing?

Just to confirm, it is working for me, I’d be lost without it and I’d like it to be working for you too.

Cheers

I think i understand what you are saying Paul,
but a split screen rendered view would simply take too much
effort to setup for what you want it for, seeing that the split
screen feature doesnt show up in renders!

I would never contemplating doing this on an on going basis just as an experiment to trying out. I thought that this might be a good way to try out some filters to be able to display it on a large screen TV & I could then see just how effective these filters are. I thought that for instance the sharpen filter might best be judged large screen.

Thanks in advance

i am not really sure if i understand. you wanna have a video with split screen comparison filter on/off?
.
two video tracks. two events one over another on those tracks. one track is no filters, another is filters on.

use event PAN/CROP or TRACK MOTION to the upper event or track, move it left or right depending on which half of the picture you want to show.

you can also use newblue filter “splitscreen” i guess is its name.

that is all
take care

Assuming your project is not trivial the only way I can see to do this is to render 3 times! Once with FX on, once with FX off, and a third to composite the first two together in split screen mode.

I guess you could use nested projects. Save one version of the project with no effects. Save another with the effects. Then drop those two projects into a third project and composite side-by-side. The problem is, there is no way to disable effects so you would have to manually go through and disable every video FX yourself. As Steve said, this is a lot of work.

Why would you even need this? You can use the split screen preview built into Vegas and use RAM Preview to an external monitor. That should give you exactly what you are looking for and it only takes seconds to set up.

It would seem that everyone thinks I’m crazy for asking this question in the first place. Perhaps this stems from the fact that often when I have tried using the split preview screen I can see the lines from interlacing,yet it’s rarely seen in the finally rendered out file.

I was only contemplating trying doing this with older analog footage. Maybe I just need to tell the program that the output will be progressive? It would be nice to see in the preview window what I expect to see when the project is finally rendered out. Perhaps my setting are wrong?

Thanks in advance

That’s what the Secondary Display is for. The preview is just a preview for editing. If you want to see the final output you need to use the Windows Secondary Display option and you can tell it to deinterlace so that you can check interlacing problems.
