vray animation..

[shikodesign2000]

Hi,

 

After I make one shot in architectural animation, I found that the video is not stable, a lot vibration pixels are very obvious especially on trees parts.

 

I rendered the shot in max as avi format, uncompressed, then I export the video from adope premiere as avi.

 

Is there any options in vray I have to take care before making the animation?

 

Or it is better to render the animation as image sequence then gathering, than making it as avi file format?

The vibrating pixels could be down to a whole load of things, I would test and see whats causing them. Start with the obvious things like GI, filter, etc.

 

Also, never render as an AVI, or any other video format. Always render as stills, and compile them afterwards. You have more control, you can re-render frames easier, and you wont have any artifacts from any compression a video format may put on your animation.

Thanks a lot, and I think I have to adjust some settings, also, rendering images sequence is more pro. ofcourse.

 

I just want to ask about the best format I can use to get the best result; I tried jpg, targa, png for images sequence, and I collapse each set in premiere, but I didn't get good result in final video.

 

Can I know what format is good, what basic settings I have to take care of in video editing software like premiere? and ofcourse with good file size.

I use openEXR format as its 32 bit float, and doesnt compress. Just use a lossless format and you should be OK, oh and make sure you have plenty of harddrive space!!!

In fact, I used uncompressed, but the problem stills, I had a quick look on this issue here and at other places online, I realized that I have to raise some essential settings, like making current preset to high animation, HSph. to 60 or 80 subdivision, interp. samples to 20, and also light cach subdivision to 1000, and so on in that way, I found that increasing these values is impossible cause it will increase rendering time too much.

 

I don't know if there is a real solution to make quality animation with vray or not? I have pc: i7 , 12 gega ram, h.d. 1 tera

You could bake all your textures and then you wouldnt need to calculate GI at all for rendering, so long as you dont have any moving objects, and the time to bake all your materials!

also if Light Cache is set to Screen instead of World could cause pixel swimming for animations..

increasing your GI wont make much of a time difference overall if its pre-calculated...

 

what will make a difference is your sampling settings - this will make pixels 'shimmer' if set low.

its impossible to help you without pictures and settings.
