ALAC stores lossless audio in Apple's M4A container. WMV (Windows Media Video) is Microsoft's video format using the ASF container. Converting ALAC to WMV bridges Apple's lossless ecosystem with Windows video environments.
The lossless ALAC source provides perfect PCM for WMA encoding within WMV, producing the best possible Windows Media audio quality.
Some Windows-based systems (PowerPoint, digital signage, corporate media servers) require WMV format. Converting ALAC to WMV with a static image creates compatible content for these environments.
The lossless source ensures optimal WMA audio quality within the WMV container — a single lossy step from perfect PCM.
FFmpeg decodes ALAC to perfect PCM and encodes to WMA (wmav2) within an ASF container with .wmv extension. A static image is encoded as the video stream. The lossless source means only one lossy step occurs, producing optimal WMA quality.
WMA at 192 kbps from lossless ALAC produces the best possible WMA quality for that bitrate. The single lossy step from perfect PCM is superior to transcoding from other lossy formats.
