Nearly all DV camcorders and decks have [[IEEE 1394 interface|IEEE 1394]] (FireWire, i.LINK) ports for digital video transfer. This is usually a two-way port, so that DV video data can be ''output'' to a computer (DV-out), or ''input'' from either a computer or another camcorder (DV-in). The DV-in capability makes it possible to copy edited DV video from a computer back onto tape, or make a lossless copy between two mutually connected DV camcorders. However, models made for sale in the [[European Union]] usually had the DV-in capability disabled in the firmware by the manufacturer because the camcorder would be classified by the EU as a video recorder and would therefore attract higher duty;<ref>{{cite web |url=http://www.dvdoctor.net/forums/why-dv-input-disabled-most-digital-camcorders-sold-europe/index.html |title=Why Is the DV Input Disabled on Most Digital Camcorders Sold in Europe? |date=5 April 2001 |access-date=1 February 2020 }}</ref> a model which only had DV-out could be sold at a lower price in the EU.

When video is captured onto a computer it is stored in a container file, which can be either raw DV stream, AVI, WMV or QuickTime. Whichever container is used, the video itself is not re-encoded and represents a complete digital copy of what has been recorded onto tape. If needed, the video can be recorded back to tape to create a full and lossless copy of the original footage.

Some camcorders also feature a [[USB 2.0]] port for computer connection. This port is usually used for transferring still images, but not for video transfer. Camcorders that offer video transfer over USB usually do not deliver full DV quality; usually it is 320x240 video, except for the Sony DCR-PC1000 camcorder and some Panasonic camcorders that provide transfer of a full-quality DV stream via USB by using the [[USB video device class|UVC]] protocol. Full-quality DV can also be captured via USB or Thunderbolt by using separate hardware that receives DV data from the camcorder over a FireWire cable and forwards it without any transcoding to the computer via a USB cable<ref>{{cite web |url=http://www.dvmp.co.uk/dv-capture-over-usb.htm |title=How to Capture DV Video via USB |work=dvmp.co.uk }}</ref> or a Firewire to Thunderbolt adapter<ref>{{cite web |url=http://www.dvmp.co.uk/dv-capture-over-thunderbolt.htm |title=How to Capture DV Video via Thunderbolt on Windows |work=dvmp.co.uk }}</ref> - this can be particularly useful for capturing on modern laptop computers which usually do not have a FireWire port or expansion slot but always have USB or Thunderbolt ports.

High end cameras and [[VTR]]s may have additional professional outputs such as [[Serial digital interface|SDI]], [[Serial Data Transport Interface|SDTI]] or analog [[component video]]. All DV variants have a [[time code]], but some older or consumer computer applications fail to take advantage of it.
