I seem to recall in past discussions that even when working with stills or progressive video the deinterlace method in Vegas project settings can affect the render quality. Is this true? I do a lot of panning/zooming on 4k footage and still images and I'm wondering what is best and if the new mode in Vegas 14/15 called "smart adaptive" is any better and what GPUs work for it.
Thanks, Marc
I think this is a misunderstanding. It affects the rendering when using interlaced footage even if you don't deinterlace for the output (e.g. when scaling). But I'm not aware of any affect when using progressive to progressive. It should be set to "None" then.
Here is one of those old discussions: https://www.vegascreativesoftware.info/us/forum/vegas-deinterlace-my-new-understanding--73998/
From Laurence's last comment there:
"What I'm saying is you may as well select a deinterlace method (I use blend fields) in your project properties, because Vegas will only use it when it needs to..."
Here is another discussion worth reading: https://www.vegascreativesoftware.info/us/forum/deinterlace-method-for-source-project--96167/
I've had mine set to "Interpolate fields" for many years, even if I'm working with progressive footage. I think it's ignored if your media is progressive, so no need real need to set it to "None".
Smart adaptive is pretty good if you actually need to deinterlace. Not sure what GPUs it requires. I guess if a GPU is available and works for "GPU acceleration of video processing" then it will work for that.
Got it, thank you.
