Media Server can encode images to disk.

There are several reasons you might want to do this:

You can encode images in one of several formats. If you intend to use the images for training, HPE recommends using a format that is not compressed, or uses lossless compression. PNG is a good choice for training images. The JPEG image format uses lossy compression to reduce file size and, as a result, the quality of the image is reduced. This makes JPEG images unsuitable for training but the smaller file size is advantageous if you intend to use the images in a front-end that might be viewed over the web.
