Vray and Render Mask problem

[branskyj]

Hi all,

I am doing an interior scene in VRay. It's an office, day time. I have already rendered the animation (660 frames, took me 2 weeks). I am trying to isolate the whole scene from what is outside of the windows (I have currently a static HDRI and want to replace it with real life footage). For that purpose I use Render Mask.

And here is the problem- once I stack up the videos (the office animation, the Render Mask and the real life footage) in Premiere I get some nasty aliasing left over from the mask. It's not a lot, only around the edges of some objects but it is visible.

What is the normal procedure with Render Mask? I also tried rendering the mask with twice the resolution of the animation and then resized it to the appropriate size- same thing.

I just want to place the animation minus the current background image, put a nice real life video under them and get a CLEAN output with no leftovers.

 

Thanks a lot

@acjwalker - 'Premier is shit' made me laugh a little bit then, after seeing your tweets the other night. Didn't solve it then?

Premiere is ok for editing, rubbish for encoding.

 

I tend to spit out of premiere as uncompressed quicktime and then put that into Procoder which does a fine job of compression.

 

And yes AFX appears to be better than premiere which seems incredibly odd as you'd have thought they both worked on the same platform, both being Adobe and all that.

premiere is great for ecoding nowdays!

what are you guys drinking?

I almost always encode my final stuff thru Premiere. I do all my heavy stuff in After Effects and do the final encoding from Premiere. Works well enough when you have the settings right.
