Help with Camera Issue

[peterstephenson]

I am having trouble with a scene that I am rendering for work. a standard installation guide for one of our products. I have done long scenes in the past and had not trouble with the renders before. I have provided a link to the scene below with the problem I am having.

As you can see, the camera shifts multiple times toward the end of the video and seemingly does it randomly. I have run low resolution test renders of the entire scene before rendering at 1080p and there were no shifts so I thought I was ok to proceed. there are no animation points for the camera or target in the timeline when the camera shifts.

 

my computer isn't the best so i am rendering individual frames and rendering about 40 or so each night but I can't seem to find a solution to this problem. Any help would be appreciated.

 

Thanks

Btw, what renderer?

Are you using perspective correction in your camera??

I don't understand when you explain that you are "rendering individual frames and rendering about 40 or so each night"

This mean that you start your render when you leave for the day?

are you sue you didn't change the proportions or size of your output image by mistake in one of those submissions?

 

What you could do is setup Backburner in your machine,(Master and slave) and submit your animation. then when you need to work in your computer, just pause the rendering in Backburner, then later in the day start the rendering again. this way you avoid any mistake that could be made in submitting the file several times.

Apologies for the vagueness of my initial post. I left the post last thing on friday before leaving work so rushed it out. I am using Vray 3.20.02 in response to the first reply. In response to "rendering individual frames and rendering about 40 or so each night", I meant that the file is very large and my computer can't really do much more when the file is open so I render frames of the animation every night instead of rendering the whole animation as a video file and then I save and close the file on a morning and open it again before I leave work.

Well you should never save straight to video any ways, there are too many thing that can go wrong while rendering and you can loose hours of work.

Always save a JPG, TGA, EXR or whatever you please. Then put it together in any video application or even the same ram player of 3D Max.
