Which statement best describes MOV file characteristics?

• A. They are the default for YouTube uploads.
• B. They always have smaller file sizes than MP4.
• C. Good quality and compatible with YouTube for streaming, but larger file sizes than MP4.
• D. They cannot be streamed over the internet.

Answer: (C)

MOV is a QuickTime container that’s designed to hold high-quality media and works well for editing, often using codecs like ProRes. Because it can preserve very high quality, the files tend to be larger than MP4 when you compare similar content and settings. MP4 is the more universal, efficiently compressed format used for online streaming, which is why it usually has smaller file sizes and broad compatibility across devices and platforms. YouTube does accept MOV uploads, but MP4 with H.264/HEVC typically offers the best balance of quality and size for streaming. So the statement is best because it acknowledges the strong quality and YouTube compatibility of MOV while noting the common trade-off of larger file sizes compared with MP4.
