USB DV Capture

WinDV was originally designed for FireWire (IEEE 1394) DV devices. However, a small number of camcorders support full-resolution DV streaming over USB. This document covers USB DV compatibility and known working configurations.


Background

Most MiniDV camcorders use USB only for:

  • Transferring still photos from a memory card
  • Low-resolution “webcam” mode

These modes do not deliver raw DV data and are not compatible with WinDV.

A few camcorder models, primarily from Panasonic, support streaming full-resolution DV data over USB 2.0. When connected in this mode, the camera appears as a DirectShow capture device exposing MEDIATYPE_Interleaved – the same media type used by FireWire DV devices. WinDV’s device filter recognizes these devices and lists them in the device selection dialog.


Enabling USB DV Streaming

On supported Panasonic camcorders, USB DV streaming must be enabled in the camera menu:

  1. Set the camera to VCR/Playback mode
  2. Open the menu and navigate to USB FUNCTION
  3. Set it to Motion DV (not “WEB CAMERA” or “PictBridge”)
  4. Connect the camera via USB to the PC
  5. Start WinDV and select the device

The setting name “Motion DV” refers to Panasonic’s MotionDV Studio software, which was originally required for USB capture. On modern Windows (7/10/11), the camera is recognized without Panasonic’s proprietary drivers.


Known Compatible Models

Panasonic (confirmed USB DV streaming)

These models have been reported to deliver full-resolution DV over USB 2.0. The NV prefix is for PAL models, PV is for the equivalent NTSC models.

PAL Model NTSC Model USB DV Notes
NV-GS400 PV-GS400 Yes Tested on Win 7/10/11
NV-GS500 PV-GS500 Yes Tested on Win 7/10/11
NV-GS300 PV-GS300 Likely Higher-end model
NV-GS320 PV-GS320 Likely Higher-end model
NV-GS330 PV-GS330 Likely Higher-end model

Panasonic (USB for photos/webcam only)

These models have USB ports but are not known to support full-resolution DV streaming over USB. Use FireWire (DV port) for tape capture.

PAL Model NTSC Model USB DV Notes
NV-GS25 No USB = photos/webcam only
NV-GS35 PV-GS35 No USB = photos/webcam only
NV-GS75 PV-GS75 No USB = photos/webcam only
NV-GS150 PV-GS150 No USB = photos/webcam only
NV-GS180 PV-GS180 Unclear Check menu for “Motion DV”
NV-GS230 PV-GS230 Unclear Check menu for “Motion DV”
NV-GS250 PV-GS250 Unclear Check menu for “Motion DV”

Canon (confirmed USB DV streaming)

A few Canon models also support DV over USB. The camera menu setting is VCR SETUP > AV-DV > OFF.

  • Canon Optura 60
  • Canon Optura 500
  • Canon Optura 600

Sony (no USB DV streaming)

Most Sony camcorders do not support DV streaming over USB. However, a few models are known exceptions.

Model USB DV Notes
DCR-PC1000 / DCR-PC1000E Yes Tested with WinDV 1.2.4

Most other Sony camcorders support USB streaming but not raw DV quality – they deliver compressed video instead. Use FireWire (i.LINK) for DV tape capture on those models.

If you have a Sony camcorder that works with WinDV over USB, please report it so this list can be updated.


How to Check if Your Camera Supports USB DV

  1. Look in the camera menu for a “DV Streaming” or “Motion DV” USB function setting
  2. If the menu only shows “WEB CAMERA” or “PictBridge”, USB DV is not supported
  3. When connected via USB in the correct mode, the device should appear in Windows Device Manager as “Panasonic DVC DV Stream Device” or similar

Technical Details

When a camcorder streams DV over USB, it registers as a DirectShow video capture device under CLSID_VideoInputDeviceCategory. The device exposes output pins with MEDIATYPE_Interleaved – the same media type used by FireWire DV devices.

WinDV’s device enumeration filter (in EnumVideoDevices(), DShow.cpp) checks for MEDIATYPE_Interleaved on output pins. USB DV devices that expose this media type are automatically listed in the device selection dialog alongside FireWire devices. No code changes are needed.

If a USB DV device uses MEDIATYPE_Video with a DV subtype (MEDIASUBTYPE_dvsd, MEDIASUBTYPE_dvhd, or MEDIASUBTYPE_dvsl) instead of MEDIATYPE_Interleaved, it will not appear in the device list. Please report such devices so the filter can be extended.


Troubleshooting

Device not listed in WinDV:

  • Verify the camera is in VCR/Playback mode (not Record)
  • Check that the USB function is set to “Motion DV”
  • Try disconnecting and reconnecting the USB cable
  • Some cameras must be powered on before connecting USB

Panasonic GS400 detection issue:

The GS400 may not be detected if it is connected via USB and then powered on. Workaround: power on the camera first, then connect the USB cable.

Low resolution or no video:

If you see low-resolution video, the camera is in webcam mode, not DV streaming mode. Change the USB function setting in the camera menu.
