A MOV file is a multimedia video file that Apple first created for their QuickTime media playback application. A MOV file can contain audio and video in a highly compressed format, using a number of different codecs for maximum flexibility.
Internally, a MOV file is arranged as a series of independent tracks. These tracks can contain audio and video; allowing these two different data types to be separated ensures playback is always in sync.
Although there are other popular formats, such as MP4, MOV files are still very much in demand due to their flexibility, and with the backing of Apple, this ensures there is widespread support for the format amongst video editing software.

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.
The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.
One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colours down to 256 or 16 colours to help reduce the file size of the PNG.
