What is an FLV file?

Flash Video

Developed By
Adobe Systems
Initial Release
2002
MIME Type
video/x-flv

The FLV (Flash Video) format is a container file format defined by Adobe Systems for delivering synchronized audio and video over the internet via the Adobe Flash Player. It supports various codecs, historically Sorenson Spark and VP6, and later H.264 (MPEG-4 AVC) and AAC audio. FLV files were the dominant standard for web-based streaming video (YouTube, Hulu) during the 2000s, utilizing the RTMP (Real-Time Messaging Protocol) for transmission before being superseded by HTML5 standards.

How to open an FLV file

Since the End-of-Life (EOL) of Adobe Flash Player in 2020, browsers no longer support FLV natively. To play local FLV files, users must utilize third-party media players that maintain legacy codec support, such as VLC Media Player, MPC-HC, or MPV. For editing or conversion, tools like OBS Studio and HandBrake utilize the FFmpeg library to decode and process the container.

What is a MOV file?

QuickTime File Format

Developed By
Apple Inc.
Initial Release
1991
MIME Type
video/quicktime

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.
