Frequently Asked Questions
Will converting M4V to FLV reduce video quality?
The conversion process optimizes video for Flash compatibility while maintaining good quality. However, FLV uses different compression methods (VP6/Sorenson Spark) than M4V’s H.264, so some quality changes are expected. Convertify’s intelligent encoding minimizes quality loss during conversion.
Can I convert DRM-protected M4V files from iTunes?
No, DRM-protected M4V files purchased from iTunes cannot be converted due to digital rights management restrictions. Only DRM-free M4V files (like personal recordings or unprotected content) can be converted to FLV format.
Why would I need FLV format when Flash Player is deprecated?
FLV conversion is useful for maintaining legacy websites, archiving content for older systems, supporting Flash-based applications, and ensuring compatibility with existing infrastructure that still requires FLV format for video playback.
How much smaller will my files be after converting to FLV?
FLV files are typically 20-40% smaller than equivalent M4V files due to different compression algorithms. VP6 and Sorenson Spark codecs used in FLV are optimized for web streaming and generally produce smaller file sizes than H.264.
Can I convert multiple M4V files to FLV simultaneously?
Yes, Convertify supports massive batch processing, allowing you to convert thousands of M4V files to FLV format in a single operation. Simply drag and drop all your files, and the converter will process them automatically.
Will the converted FLV files work in modern browsers?
Most modern browsers have discontinued Flash Player support, so FLV files won’t play directly in current browsers. However, they’ll work in specialized Flash players, legacy systems, and applications that still support Flash content.
Does the conversion preserve video metadata and timestamps?
Basic metadata like duration and dimensions are preserved, but FLV format has limited metadata support compared to M4V. Some advanced metadata fields from the original M4V file may not transfer to the FLV format due to container limitations.
Can I adjust video quality settings during M4V to FLV conversion?
Convertify automatically optimizes conversion settings for best quality-to-size ratio. The Pro version includes advanced settings that allow you to customize video bitrate, resolution, and codec parameters for specific quality requirements.
