When you say "the time of the show", do you mean the total duration of the animation you have made?

Xara3D does not set a show duration of 1 minute. The duration will be set by the duration of individual frames times the number of frames. The user can set either or both of these to meet the user's needs at the user's will within Xara3D's animation dialogue box with Frames per cycle, and Frames per second settings. If you need the animation to take longer, you can either set fewer frames per second, or use more frames to achieve the full cycle, or both.

Xara3D was never intended for creation of animated movie clips, but for simple text and/or graphic logo animations for web sites. A resolution limit of 2000x2000 pixels is still not a serious limitation in the web world.

Perhaps you could provide more information on your animation? It is a little hard to provide more specific help without a better idea what the issue is. It is often the case that a little lateral thinking can sidestep the problem, and with Xara3D there is almost always more than one way to skin a cat.
