What is a MOV file?

The MOV filename extension represents the QuickTime File Format (QTFF), a proprietary multimedia container developed by Apple Inc. It serves as the structural basis for the ISO/IEC 14496-14 (MPEG-4 Part 14) standard. The format utilizes an atom-based structure where data is organized into hierarchical units, allowing it to contain multiple tracks of video, audio, timecode, and text (subtitles). Common codecs encapsulated within MOV containers include Apple ProRes, H.264, and HEVC for video, and ALAC or AAC for audio. It is the default recording format for iPhones and iPads.

How to open a MOV file

MOV files are the native format for macOS and open directly in QuickTime Player. On Windows, native support is available in modern versions of Windows Media Player, though legacy support relied on the now-deprecated QuickTime for Windows. For cross-platform compatibility and to handle professional codecs like ProRes on non-Apple systems, VLC Media Player or Adobe Premiere Pro are the recommended tools.

What is an AAC file?

Advanced Audio Coding (AAC) is a lossy digital audio compression standard defined by ISO/IEC 13818-7 (MPEG-2) and ISO/IEC 14496-3 (MPEG-4). Developed by a consortium including Bell Labs, Fraunhofer IIS, and Dolby Laboratories as the successor to MP3, AAC utilizes the Modified Discrete Cosine Transform (MDCT) algorithm and perceptual noise shaping to discard imperceptible signal components. It supports up to 48 audio channels, arbitrary sample rates, and utilizes extensions such as Spectral Band Replication (SBR) to achieve higher fidelity at lower bitrates than predecessor formats.

How to open an AAC file

AAC serves as the default audio container for Apple's iTunes and iOS devices, ensuring native support within the macOS Core Audio framework and Apple Music. Windows 10 and 11 provide native decoding support via the Groove Music and Windows Media Player applications. For cross-platform playback or advanced stream analysis, users should utilize VLC Media Player or FFmpeg, which contain the necessary libavcodec libraries to decode AAC streams without external codec packs.
