What kind of file can you convert to create vector shapes in Adobe After Effects?

In Adobe After Effects, vector shapes can be created from Illustrator files, specifically those with the .ai extension. This is because Illustrator is a vector graphics editor, and the .ai file format preserves the vector information essential for scaling and editing. When you import an Illustrator file into After Effects, you can choose to convert the layers into editable vector shapes, which allows for greater flexibility and scalability in your animations.

Conversely, the other file formats listed do not support vector data. JPEG and PNG files are raster image formats that rely on pixels rather than vectors, making them unsuitable for vector shape conversion. Although Photoshop files can contain vector paths, they are primarily categorized as raster images when imported into After Effects, and may not provide the same level of editing capability as Illustrator files. Therefore, using Illustrator files is the correct method for creating vector shapes in Adobe After Effects, reinforcing why this choice is the best option.
