While the dimensions a animated GIF should have can be specified exactly in GrabzIt you can also just specify one dimension with the other defined as -1.
This will scale the video to the size of the specified dimension, the other unspecified dimension will also be reduced in the same ratio. However the size of the unspecified dimension will of course vary depending on the dimensions of the source video.
The advantage of this technique is that it allows an entire video to be scaled down to a small size without any padding or cropping. Below is an example showing a animated GIF with a width of 200px and the height being auto-sized depending on the ratio of the 200px width to the source video width.

When calculating the Total Resolution of the Animated GIF, to determine if it is allowed on your current package, the value of the non-auto-sizing dimension is used instead.
