Corel Painter supports importing and exporting numbered files. Numbered files are any series of files that are the same size and resolution, and named following a specific style, which includes a number at the beginning or end of each file name. For example, the first frame might be called "Movie01," the second frame "Movie02," and so on.
When you export a movie as numbered files, you can import the numbered files into an application that may not support other movie formats. When exporting, you specify the filename for the first file. You must include zeros so that all numbered files have the same number of digits. For example, to create numbered files from 1 to 24, include "01" in the filename. To create numbered files from 89 to 110, include "089" in the filename.
Importing numbered files is an excellent method of bringing an animation from another 3D or animation program into Corel Painter. The file format of the numbered files you are importing must be supported by Corel Painter, and the number of digits in each filename must be the same. When you import numbered files, you create a new frame stack, and you are prompted to choose a number of onion skin layers and a storage type.
