Resizing Project to very high resolution fails.

[Animark]

Hi,

I want to resize my 1920px x 1080px project to 10100px x 5680px. It's for a bg where I want to zoom back from very close to very total.
When I try to resize to the new size, TVP starts working, but ending up in a delay. The progress bar stops at 0%. TVP uses about 700 MB of Ram (there are 2GB in the slots) and 50% of the cpu.
(System = Windos XP SP2)

Is there a limitation of project size?
Is there a workaround to solve that problem (ram / cache usage)?

Yes, I could try to paint that bg in Photoshop. The project size don't makes any trouble there, but I want to use the TVP Tools.

Thanks from Animark.

I managed to create a project of 10100 x 5680 pixels.
I admit my first attempt ended up in TVP not responding, and then I terminated its process.
but once restarted I created the file easily.

what's the size of your cache? and on which drive is it?

[Animark]

I will come back tomorrow, cause the problem exists at my working place, where I can have a closer look at cache and friends. I don't have TVP here at home --- not yet

So, I don´t really understand how to manage the cache. I think, it is managed automatically by TVP at the moment. Should I increase or decrease it?
Doesn't the auto-setting means, that TVP takes as much cache as it needs - managing it dynamically?

I also think, that the cache is not on a harddisk drive. Its made of ram, isn't it? Is there another cache?
Are there possibilities to mix some ram and some diskspace to get more ressources for my project size?

Your planned BG is roughly 165 MB big when opened. This will be only one layer in 24bit RGB, mind you. For Photoshop there was the rule of thumb to have at least three times as much memory in RAM reserved for the program as the open file needs: one for the open file, one for the version you're creating, and one version for Undo. In your case this would be 495 MB just to open that file and allow one level of undo. With your 2 GB RAM I don't see much of a problem - as long as you only have one layer! The more layers you have, the slower TVP responds (my observation).

Some tricks: start with a freshly rebootet machine and freshly started TVP. Create the empty file in Photoshop and just import it to TVP. Make sure not to have something big in the clipboard.

An inventive workaround for this (that Eric clued me into)is to split up the image you want to zoom in on into a number of images of the same size each representing a fase of the zoom(in the example image they are 1920x1280)
and then stack them on top of each other in the multiplane camera (make sure to put them all on the same z-depth but still have the smaller ones showing in front of the bigger ones) each image should be scaled to fit in the previous.
it takes some fiddeling and calculating (well... maybe quite a lot) but once you have set it up you can theoraticly make a zoom without any pixelsize limits without straining your system resources!

OK, i solved my problem.
I reduced my zoom back a little bit so that I can work with a resolution of ca. 7000 x 4000 pixel. The story of my film is also working with a little bit less zooming . Generally I think, my problem was based on ram limitation.

I think about Peter`s solution - for future situations. I am not sure if it is working, because I can imagine, that there will be some trouble with different line thicknesses.
Did anybody testet this workaround? I think it`s just a theoretical solution, because I also cannot imagine how I can draw the different pictures so, that they will fit perfectly while zooming. Maybe I am wrong.

I found that I can rig a multiplane setup before I even start drawing, just with empty layers. This works for normal multiplane stuff with planes with different Z, but identical % settings. It doesn't work for setups with different % settings.

for fun indefinate zooming check this out:

you can see some issue with linethickness/sharpness but they do fit perfectly.

This gimmick also demonstrates the limit of zooms, they cannot replace camera movement because the perspective remains static.
To really get a sense of motion the perspective of the different elements should be constantly changing.
