## Rendering Animations

Relevant to Blender v2.31

The rendering of an animation is controlled via the `Anim` Panel (Figure 17.16, “Animation rendering buttons.”).

Figure 17.16. Animation rendering buttons.

The `ANIM` button starts the rendering. The first and last frames of the animation are given by the two NumButtons at the bottom (`Sta:` and `End:`), and by default are 1 and 250.

By default the 3D scene animation is rendered, to make use of the sequence editor the `Do Sequence` Tog Button must be selected.

By default the animation is rendered in the directory specified in the `Output` Panel (Figure 17.17, “Animation location and extensions.”). If an AVI format has been selected, then the name will be `####_####.avi` where the '####' indicates the start and end frame of the animation, as 4 digit integers padded with zeros as necessary.

Figure 17.17. Animation location and extensions.

If an image format is chosen, on the other hand, a series of images named `####`, ('####' being the pertinent frame number) is created in the directory. If the file name extension is needed, this is obtained by pressing the `Extensions` Tog Button (Figure 17.17, “Animation location and extensions.”).

### Complex animations

Unless your animation is really simple, and you expect it to render in half an hour or less, it is always a good idea to render the animation as separate Targa frames rather than as an AVI file from the beginning.

This allows you an easy recovery if the power fails and you have to re-start the rendering, since the frames you have already rendered will still be there.

It is also a good idea since, if an error is present in a few frames, you can make corrections and re-render just the affected frames.

You can then make the AVI out of the separate frames with Blender's sequence editor or with an external program.
