Convert WTV to DV — Free Online Tool
Convert WTV recorded TV files from Windows Media Center into DV format, re-encoding the video stream with the dvvideo intra-frame DCT codec and audio to uncompressed PCM — ideal for importing broadcast recordings into DV-native editing workflows and legacy camcorder-based pipelines.

DownloadHow It Works
WTV files typically contain H.264 video and AAC audio captured from digital broadcast tuners by Windows Media Center. Converting to DV requires a full transcode of both streams: the H.264 video is decoded and re-encoded using the dvvideo codec, which uses intra-frame DCT compression (every frame is independently compressed, with no inter-frame prediction). The AAC audio is decoded and re-encoded to 16-bit little-endian PCM (pcm_s16le), which is uncompressed and required by the DV container. The output conforms to DV's strict format constraints, including fixed resolution (typically 720x480 for NTSC or 720x576 for PAL) and a fixed bitrate, so FFmpeg will scale or pad the source video to meet those requirements.
What Each Flag Does
| Flag | What it does |
|---|---|
ffmpeg
|
Invokes the FFmpeg binary, the open-source multimedia processing engine that handles all decoding, encoding, and container muxing for this WTV-to-DV conversion. |
-i input.wtv
|
Specifies the input Windows Television file recorded by Windows Media Center, which FFmpeg will demux to extract the H.264 video stream, AAC audio stream, and any subtitle or metadata streams for processing. |
-c:v dvvideo
|
Instructs FFmpeg to re-encode the decoded H.264 video frames using the dvvideo codec, which applies intra-frame DCT compression at a fixed bitrate (approximately 25 Mbps) as required by the DV format specification. |
-c:a pcm_s16le
|
Re-encodes the AAC audio from the WTV file into 16-bit signed little-endian uncompressed PCM, the only audio format supported by the DV container, resulting in lossless audio storage after the initial AAC decode. |
output.dv
|
Defines the output file in the raw DV container format (.dv), which wraps the dvvideo and pcm_s16le streams in the structure expected by DV-native editing tools, tape decks, and broadcast ingest systems. |
Common Use Cases
- Importing a Windows Media Center broadcast recording into Final Cut Pro 7 or Premiere Pro workflows that were built around DV tape-based footage for consistent timeline handling
- Archiving digitized TV recordings into DV files for ingestion into legacy broadcast editing suites that only accept DV or DVCAM input
- Preparing recorded TV content for output to a DV tape deck or camcorder for physical archival or distribution via tape
- Standardizing a mixed library of Windows Media Center recordings to a single DV format for editing consistency across a project
- Converting a WTV sports or news recording for use in a DV-based clip server or playout system used in small broadcast facilities
Frequently Asked Questions
Yes, some quality loss occurs because both the video and audio are fully re-encoded. The WTV file's H.264 video is decoded and then re-compressed using dvvideo's intra-frame DCT codec, which operates at a fixed bitrate (approximately 25 Mbps for standard DV) regardless of the source quality. Additionally, DV enforces a fixed resolution, so if your WTV recording was captured at 1080i or 720p, it will be downscaled to standard definition (720x480 NTSC or 720x576 PAL), which is a significant resolution reduction.
DV is a legacy format originally designed for consumer and prosumer camcorders and supports only a single stereo audio track in its container. WTV files from Windows Media Center can carry multiple audio tracks — for example, a secondary language track or a secondary audio program (SAP). FFmpeg will map the first audio track by default during this conversion; any additional audio tracks in the WTV file will be discarded. If you need a specific alternate track, you can add '-map 0:a:1' to the command to select it.
No. WTV files embed rich metadata including program title, episode information, channel name, broadcast timestamps, and Electronic Program Guide (EPG) data. The DV container has no support for this kind of metadata, so all of it is lost during conversion. If preserving this information matters, consider extracting and saving it separately before converting, using a tool like MCEBuddy or by inspecting the WTV file's metadata streams with 'ffprobe'.
WTV files from Windows Media Center frequently contain closed caption or teletext subtitle streams captured from the broadcast signal. The DV format does not support subtitle streams of any kind, so all subtitle data will be stripped from the output file during conversion. If you need to preserve subtitles, you should extract them to a separate SRT or SCC file before running this conversion.
The base command 'ffmpeg -i input.wtv -c:v dvvideo -c:a pcm_s16le output.dv' uses FFmpeg's default stream selection. To select a specific audio track, add '-map 0:v:0 -map 0:a:1' (replacing '1' with the zero-based index of your desired track). To control the output resolution and ensure correct DV framing, you can add a scale filter such as '-vf scale=720:480,setdar=4/3' for NTSC DV. DV has no quality adjustment parameters — bitrate and resolution are fixed by the format specification.
Yes. On Windows you can run a batch loop in Command Prompt: 'for %f in (*.wtv) do ffmpeg -i "%f" -c:v dvvideo -c:a pcm_s16le "%~nf.dv"'. On macOS or Linux, use a shell loop: 'for f in *.wtv; do ffmpeg -i "$f" -c:v dvvideo -c:a pcm_s16le "${f%.wtv}.dv"; done'. Be aware that each WTV-to-DV transcode involves full video re-encoding and can be CPU-intensive, so processing large libraries will take significant time.
Technical Notes
The dvvideo codec imposes rigid constraints that make WTV-to-DV conversion more involved than a simple remux. DV standard definition supports only 720x480 (NTSC, ~29.97fps) or 720x576 (PAL, 25fps), so any WTV recording captured at HD resolutions (1080i or 720p, which are common with ATSC or DVB tuners) will be downscaled, resulting in a meaningful loss of detail. The dvvideo codec uses a fixed bitrate of approximately 25 Mbps for standard DV, which may be lower than the original H.264 stream's effective quality, especially for high-motion content. Audio is stored as uncompressed pcm_s16le at either 48kHz/2-channel or 32kHz/4-channel depending on DV mode; the default FFmpeg output is 48kHz stereo. The DV container (.dv) does not support chapters, multiple audio tracks, subtitles, or embedded metadata tags, meaning the rich broadcast metadata carried in WTV files — including program titles, ratings, and EPG information — is entirely discarded. There is no quality tuning parameter for dvvideo; output quality is determined solely by how well the fixed-bitrate intra-frame codec represents the decoded source frames.
