VIDEO TRANSFER

Digital cameras in the studio can be used import older analog video to digital in real-time. Transcoding is available but not recommended.

The Canon ZR10 camera supports IEC 61834 and it has analog inputs so it can digitally import any analog source including Beta and VHS or other formats. While analog video is crude it can be cleaned up to some extent.

The MiniDV tapes can tolerate repeated recording easily reducing costs. Additional tapes are readily available for larger projects. The standard 60 minute miniDV tapes are about 13 GB of data each. Large capacity hard disks and SSD can handle editing.

Firewire can handle all DV rates from 25 megabit and above easily so importing DV video is the best quality possible. DV also is used for 720p and 1080i video which tend to reach 45 megabit data rates which DV handles fine. Multiple cameras using Firewire can interoperate easily with computers and even hard disks. Some audio mixing boards have Firewire which allows for interoperability with Avid Pro Audio.

Older Sony Digital8 cameras can play older analog tapes along with digital tapes. The newer models dropped the analog support.

HDMI capture cards are able to handle 3840×2160 HDR streams so they can handle consumer video sources. This allows the video to be edited with Avid Media Composer.

Sony recommends using cleaning cassettes once every 50 hours of recording or playback. For those who are still skeptical, Sony recommends cleaning video heads with a cleaning cassette before trying another brand of tape.

More recent cameras now use USB to handle importing video. Cameras have now adopted various flash memory chips which have enough bandwidth to handle compressed HD and 4K formats.

12G-SDI cards are used in the modern professional studio. The allows a PC to interface with advanced edit bays. D5 tape has given way to dual SSD based units that pop right into the rack and even have the RS242 serial control lines to connect to the remote control.

Some professional rigs have both HDMI and SDI cards to handle equipment. Red professional cameras generally swap out the SSD which is easier to use and a low cost adapter is readily available. Copying the raw video to a high capacity hard disk or SSD array is easy.
