I assume you are asking about our pricing page. The price is mentioned both at the top of the table and at the bottom, so people with small monitors can see it when they have the page scrolled. So it’s for convenience only
The time a render takes can’t be estimated without the file actually rendering. Not even Blender, with the file opened in it, provides such an estimate. Generally speaking though, we can allocate enough servers to get the animations rendered fast enough (two hours or less depending on how many frames).
For still images, we have an option to break the image into parts and render it on multiple machines so it speeds it up. The stitching is done automatically after each part is rendered and you can preview the render as soon as a part is done rendering.
