Convert MOV to FLV Online
Transform your QuickTime MOV files into Flash Video (FLV) format with our online conversion tool. MOV is Apple's professional video format used in Final Cut Pro and across the Apple ecosystem, while FLV is a legacy web format from the Flash era.
How to Convert MOV to FLV
Converting your video files is straightforward. Upload your MOV file using the tool above, and the conversion process begins automatically. The converter processes your QuickTime video and generates an FLV file suitable for legacy Flash applications. Once complete, download your converted file for use with older web platforms or archived Flash systems.
Why Convert MOV to FLV
While FLV is a legacy format no longer recommended for modern applications, conversion may be needed for specific archival or compatibility purposes. MOV files from Apple devices and professional editing software offer excellent quality and advanced features but may not be compatible with legacy Flash-based systems. FLV was designed for Adobe Flash Player and is now obsolete since browsers discontinued Flash support. This conversion is typically only useful for maintaining old Flash applications, archiving historical content, or compatibility with legacy streaming systems. For modern web use, consider MP4 or WebM instead of FLV.
Video Quality and Compatibility
MOV files support high-quality codecs including H.264, H.265, ProRes, and others, making them ideal for professional video work. FLV uses older compression technology optimized for Flash Player streaming. Converting from MOV to FLV typically results in reduced quality and limited codec options due to FLV's legacy design. FLV has virtually no compatibility with modern systems, as browsers and devices no longer support Flash. This conversion should only be used when absolutely necessary for legacy requirements. For better quality and modern compatibility, keep content in MOV or convert to MP4 or WebM.
Common Use Cases
- Archiving legacy content in FLV format for historical purposes
- Converting videos for compatibility with old Flash-based systems
- Maintaining archived Flash applications and streaming platforms
- Preparing content for legacy e-learning systems requiring FLV
- Converting videos for outdated video management platforms
- Supporting specific legacy requirements in older corporate systems
Format Comparison
MOV is Apple's QuickTime container format that supports a wide variety of professional-grade codecs and is the standard for video editing on Mac platforms. It offers excellent quality, advanced features, and seamless integration with Apple devices and editing software like Final Cut Pro. FLV is a legacy container developed by Adobe for Flash Player with limited codec support and basic features. While MOV is designed for professional workflows and high-quality distribution, FLV is obsolete and has no place in modern video applications. Converting from MOV to FLV is generally not recommended except for very specific legacy system requirements.
Technical Conversion Limitations
MOV files may contain video encoded with H.264, H.265, ProRes, or other advanced codecs that FLV doesn't natively support. During conversion, video must be transcoded to FLV-compatible formats like H.263 (Sorenson Spark) or limited H.264. ProRes or HDR content loses significant quality in this process since FLV's legacy codecs cannot preserve modern video features.
Multi-track audio, chapter markers, and metadata common in professional MOV files are stripped during FLV conversion. FLV supports only single audio tracks and basic metadata. If your MOV contains multiple audio languages or extensive metadata, consider keeping the original format or converting to MP4 which preserves more features.
Better Modern Alternatives
Unless you have specific requirements for legacy Flash systems, consider converting MOV to more modern formats. MP4 with H.264 provides universal device and browser compatibility without Flash. WebM offers excellent web streaming performance with native browser support. Both formats preserve quality better than FLV and work on all current devices and platforms.
For web video delivery, HTML5 video with MP4 and WebM sources has completely replaced Flash-based FLV playback. Modern content management systems, video platforms, and browsers all support HTML5 video natively. Only convert to FLV when absolutely required by systems that cannot be updated.
