Supports: DV
.dv and .dif files both work. Batch is supported, including multi-hour tape captures.DV (Digital Video) is the tape format used by MiniDV camcorders from roughly 1995 to 2010 — the era of Sony Handycam, Canon Optura, Panasonic PV-GS series, and JVC GR-D camcorders. When you captured tapes via FireWire (IEEE 1394) into Windows Movie Maker, Adobe Premiere, or Sony Vegas, the result was a raw .dv or .avi-wrapped DV file. These files are huge — about 13 GB per hour at standard definition (25 Mbps constant bitrate, intraframe-only compression) — which is why archiving an attic full of MiniDV tapes can quickly fill a hard drive. WMV (Windows Media Video) compresses that 13 GB hour down to 1-3 GB without visible quality loss for SD content.
| Property | DV | WMV |
|---|---|---|
| Origin | Consortium of camcorder makers (1995) | Microsoft (1999) |
| Typical use | MiniDV / DVCAM / DVCPRO tape capture | Windows Media playback, streaming |
| Compression | Intraframe-only DCT (lossy video, ~5:1) | Inter-frame WMV1 / WMV2 / WMV3 (VC-1) |
| Bitrate | Locked at ~25 Mbps (SD) | Variable — typically 1-8 Mbps |
| File size (1 hour SD) | ~13 GB | ~1-3 GB at "High" quality |
| Resolution | 720×480 (NTSC) / 720×576 (PAL) | Any — preserve original or rescale |
| Audio | Uncompressed PCM (16-bit, 48 kHz) | WMA v1 / v2 (compressed) |
| Native Windows playback | Needs codec / VLC | Native in Windows Media Player |
| Edit-friendly | Yes — every frame is a keyframe | Lossy on re-encode |
| Best for | Lossless editing master | Playback, sharing, streaming |
| Setting | Recommended | Notes |
|---|---|---|
| Video codec | WMV2 | Default — works on every Windows build since XP SP2 |
| Audio codec | WMAV2 | Smaller files than WMAV1 with no audible difference |
| Quality preset | High | "Highest" doubles size with no perceptible gain on SD source |
| Resolution | Original (720×480 / 720×576) | Don't upscale — DV is locked to SD |
| Bitrate target | 2-3 Mbps | Sweet spot for SD camcorder footage |
| File size % | 10-15% of original DV | Standard archival ratio |
Some loss is unavoidable because WMV uses inter-frame compression while DV uses intraframe-only compression — but at "High" quality preset or 2-3 Mbps bitrate the loss is invisible on SD content. The DV source itself is already lossy (about 5:1 DCT compression), so you're not converting from a lossless master. For a true lossless archive, keep the original .dv file alongside the WMV viewing copy.
DV uses a fixed ~25 Mbps intraframe-only bitrate — every single frame is fully encoded with no temporal compression, so each second is the same size regardless of how much motion there is. WMV2 / VC-1 use inter-frame compression where only the differences between frames are stored, dropping a typical SD camcorder hour from 13 GB to 1-3 GB with minimal visible loss at high-quality settings.
For irreplaceable family footage, yes — keep the DV as a cold-storage master and use the WMV as your daily viewing copy. DV is the closest thing you have to the original tape (FireWire capture is bit-exact), and you can always re-encode to a newer format later. WMV is fine as a permanent viewing copy, but it's a one-way lossy step.
Both work. NTSC DV is 720×480 at 29.97 fps (North America, Japan); PAL DV is 720×576 at 25 fps (Europe, Australia, most of Asia). The converter detects and preserves the original frame rate and aspect flag. If your tape was shot interlaced (most MiniDV cameras), the WMV output stays interlaced unless you explicitly choose a progressive resolution preset.
Yes — drop in dozens of DV captures at once. A typical use case is a 50-tape MiniDV box: capture each tape via FireWire to a single .dv file, then queue all 50 in one batch. They process withon our servers and download individually. Settings apply uniformly across the batch.
Yes. The date/time overlay that many MiniDV camcorders burn into the video frame (when "Date Display" was enabled in-camera) is part of the picture, not metadata, so it survives conversion exactly as it appears in the original. If you'd rather not see it, you'd need to crop or letterbox in a video editor before converting.
Yes. DV stores uncompressed PCM audio at 48 kHz / 16-bit (or 32 kHz / 12-bit on some older cameras), and the converter re-encodes that to WMA v2 while preserving sync. Long FireWire captures (multi-tape stitched files) sometimes have drift in the original DV — if so, the drift carries through to the WMV but isn't introduced by conversion.
WMV is the right choice when your viewing environment is Windows-native — Windows Media Player, Windows Movie Maker, Windows Home Server, older DLNA TVs and PowerPoint embeds. For everything else (Mac, iPhone, smart TVs, modern web), DV to MP4 is the safer pick. Many home archivists keep both: one WMV viewing copy and one MP4 sharing copy, with the original DV as the cold-stored master.
Yes — use the trim section to set a start time and duration (seconds, e.g. 12.5, or HH:MM:SS.sss, e.g. 00:00:08.500). MiniDV tapes captured via FireWire often include a few seconds of blue-screen or static at the head before the actual footage starts, and trimming those out at conversion time saves a manual step in a video editor later.
