Convert DV to WMA — Free Online Tool
Convert DV camcorder footage to WMA audio by extracting the PCM audio track and re-encoding it as Windows Media Audio using the wmav2 codec. This is ideal for pulling clean, broadcast-quality audio from DV tape captures when you only need the sound — not the video.

DownloadHow It Works
DV files store audio as uncompressed PCM (pcm_s16le — 16-bit little-endian stereo), which is already high quality but enormous in size and incompatible with most audio players and streaming platforms. During this conversion, FFmpeg discards the dvvideo video stream entirely and re-encodes only the PCM audio track into WMA format using the wmav2 codec at 128 kbps. Because wmav2 is a lossy codec, the audio is compressed using Microsoft's proprietary psychoacoustic model, reducing file size significantly while targeting perceptual transparency at the chosen bitrate. No video data is carried into the output — the result is a pure audio file playable in Windows Media Player, older portable media devices, and any WMA-compatible application.
What Each Flag Does
| Flag | What it does |
|---|---|
ffmpeg
|
Invokes the FFmpeg tool, which handles all media reading, stream processing, encoding, and output writing for this conversion. |
-i input.dv
|
Specifies the input DV file. FFmpeg will demux the DV container, exposing the dvvideo video stream and the pcm_s16le audio stream — only the audio stream is used in this conversion. |
-c:a wmav2
|
Sets the audio encoder to wmav2, Microsoft's second-generation Windows Media Audio codec. This encodes the raw PCM audio from the DV source into the compressed WMA format that the output container requires. |
-b:a 128k
|
Sets the audio bitrate to 128 kilobits per second for the wmav2 encoder. This is the default quality level — sufficient for speech and most general audio extracted from DV camcorder recordings while keeping file sizes manageable. |
output.wma
|
Defines the output filename and format. The .wma extension tells FFmpeg to write a Windows Media Audio container, which is an audio-only format — the dvvideo stream from the DV input is automatically discarded since WMA cannot carry video. |
Common Use Cases
- Extracting interview or dialogue audio recorded on a DV camcorder for use in a podcast or radio broadcast edited in Windows-based software
- Archiving the audio commentary or narration from a DV tape capture without storing the bulky video, when the visual content is no longer needed
- Preparing audio from DV footage for upload to older digital distribution platforms or intranet systems that specifically require WMA format
- Pulling music or live performance audio recorded on a DV camcorder to distribute via Windows Media Player playlists or WMA-compatible portable players
- Reducing storage footprint of DV audio archives by converting uncompressed PCM audio from tape captures into compressed WMA files
- Extracting clean field-recorded audio from a DV shoot to hand off to an audio editor working in a Windows environment where WMA is the standard delivery format
Frequently Asked Questions
Yes — this conversion introduces lossy compression for the first time to the audio. DV stores audio as uncompressed 16-bit PCM at 48 kHz or 32 kHz, which is lossless in the audio domain. Re-encoding to wmav2 at 128 kbps applies psychoacoustic compression, discarding audio data the codec deems inaudible. At 128 kbps, most listeners find WMA audio perceptually transparent for speech and general audio, but artifacts can appear on complex musical content or high-frequency detail. If quality is critical, consider using 192 kbps or 256 kbps.
WMA is a pure audio container format — it has no capability to store video streams at all. FFmpeg automatically drops the dvvideo stream when targeting a WMA output because there is nowhere to put it. If you need to preserve the video, you should convert to a container like MP4 or MKV instead. This tool is specifically designed for audio-only extraction from DV sources.
Replace the value after -b:a in the command to adjust the WMA output bitrate. For example, use -b:a 192k for higher quality or -b:a 64k for smaller file size. Supported values include 64k, 96k, 128k, 160k, 192k, 256k, and 320k. Higher bitrates preserve more of the original PCM detail from the DV source but produce larger files; 128k is the default and a reasonable balance for most speech and general audio content.
Yes — you can substitute -c:a wmav1 in the command, but wmav1 is an older, less efficient version of the Windows Media Audio codec and generally produces lower quality at the same bitrate compared to wmav2. wmav2 is the default and recommended choice for virtually all use cases. wmav1 exists primarily for compatibility with very old devices or software that predates wmav2 support.
On Linux or macOS, you can use a shell loop: for f in *.dv; do ffmpeg -i "$f" -c:a wmav2 -b:a 128k "${f%.dv}.wma"; done. On Windows Command Prompt, use: for %f in (*.dv) do ffmpeg -i "%f" -c:a wmav2 -b:a 128k "%~nf.wma". This processes each DV file in the current directory and outputs a corresponding WMA file with the same base filename. The browser-based tool handles one file at a time, so the FFmpeg command is especially useful for batch workflows with large DV tape archive collections.
DV files carry very limited metadata — typically timecode and camcorder-specific technical data rather than standard title or artist tags. WMA supports rich metadata tags including Title, Artist, Album, and Year, but since DV sources rarely contain this information, the output WMA file will generally have no meaningful tags populated. You can add metadata manually using FFmpeg's -metadata flag, for example: -metadata title="Interview 2024" -metadata artist="Field Recording".
Technical Notes
The DV format's audio is recorded as pcm_s16le — uncompressed 16-bit signed little-endian PCM — typically at 48 kHz (four-channel 12-bit or two-channel 16-bit depending on the camcorder mode). FFmpeg reads this natively and feeds the raw PCM samples directly into the wmav2 encoder without any intermediate decoding step, preserving the full dynamic range of the source before lossy compression is applied. The wmav2 codec uses a transform-based compression model similar in concept to MP3 but with Microsoft-specific optimizations tuned for streaming. WMA files do not support multiple audio tracks, subtitles, or chapters, and DV's lack of subtitle or chapter support means nothing is lost in that regard. One practical limitation: if your DV source was recorded in 32 kHz audio mode (common on older consumer camcorders), FFmpeg will handle the sample rate difference automatically, but you may notice the WMA output reflects this lower source sample rate unless you add an explicit -ar 48000 resampling flag. File sizes will drop dramatically compared to the original DV — a one-hour DV tape capture produces roughly 13 GB of video+audio data, while the extracted WMA audio at 128 kbps will be approximately 57 MB.
