M4V에서 WMA(으)로의 변환 소개
M4V files from Apple's ecosystem store H.264 video with AAC audio, typically from iTunes or Apple TV. WMA (Windows Media Audio) is Microsoft's proprietary audio codec, developed as a competitor to MP3 and AAC. Converting M4V to WMA extracts the audio and re-encodes it using Microsoft's Windows Media Audio codec, producing files optimized for the Windows ecosystem — Windows Media Player, Zune, and older Microsoft platforms.
M4V을(를) WMA(으)로 변환하는 이유
WMA remains the preferred audio format for certain Windows-centric environments. Older Windows Media Center installations, Zune devices, and some Windows-based enterprise media systems expect WMA format. WMA also offers slightly better compression than MP3 at low bitrates (below 96 kbps), making it useful for voice recording archives on Windows systems where storage is constrained.

작동 방식
FFmpeg decodes the AAC audio from the M4V and re-encodes it using the wmav2 encoder (WMA version 2). Standard WMA supports bitrates from 48 to 192 kbps at sample rates up to 48 kHz. The output is wrapped in the ASF (Advanced Systems Format) container with a .wma extension. WMA version 2 is the most compatible variant — WMA Pro and WMA Lossless have more limited player support.
품질 및 성능
WMA at 128-192 kbps produces quality comparable to MP3 and AAC at similar bitrates. At lower bitrates (64-96 kbps), WMA typically outperforms MP3 but is roughly equivalent to AAC. Since this conversion goes from lossy AAC to lossy WMA, expect a small amount of additional quality degradation.

최상의 결과를 위한 팁
- 1Use 128 kbps WMA for a good balance of quality and file size in Windows Media Player
- 2WMA version 2 (wmav2) has the best compatibility across Windows versions and devices
- 3If cross-platform compatibility matters, prefer MP3 or AAC over WMA — WMA is Windows-only in practice
- 4For voice recording archives, WMA at 48-64 kbps provides acceptable speech quality with very small files
- 5Verify the target system supports WMA before batch-converting — many modern cross-platform apps have dropped WMA support

M4V to WMA conversion is a practical solution for Windows-centric audio needs. While WMA has largely been superseded by AAC and MP3 for general use, it remains relevant for legacy Windows media workflows.
