XPe Film Credits

Video Assist

Directors of films need to be positioned very closely to the cameras in order to anticipate the suitability and quality of footage being shot. However in many scenes this is simply not possible, either because there is action and movement or because there are a number of cameras widely spaced to cover different angles.

In these cases video assist equipment may be used to bring a TV picture of the film cameras point of view to the director. This can be done with cables but often it is not practical, cables get in the way and can not be used on mobile cameras without causing more problems.

Wireless video camera systems therefore have been used for a few years, but the older analogue type equipment has limitations, in that they really only work well in line of sight applications and they require people to point directional radio antennas in order to get the best results.

The XPe Digital Wireless Camera System

Link's XPe system uses modern video and audio encoding techniques to convert PAL or NTSC signals into a format that can be transmitted using a digitally modulated radio link.

The digital modulation technique allows the system to work in non line of sight environments and without the need for pointing transmit or receive antennas.

In built up areas ranges over 100M are easily achieved and much greater distances can be covered in more open environments. Even high speed movement can be accommodated, so action sequences can be followed seamlessly.

The list below is by no means complete, but it gives an idea of the type of applications the XPe system can be used for.

Da Vinvci Code 2006, car chase scene.

Casino Royale 2006, used throughout shooting on both tracking and staic shots.

Children of Men 2006, tracking sequences, urban gun fight.

The Holiday 2006. tracking wire shot, over the lake.

The Omen 2006, Wire shot of the point of view of the stake going through the preist's chest and other tracking shots.

Blood and Chocolate 2007, Wire rig tracking shots in forest etc.

Bourne ultimatum 2007, wire rig and action sequences.

Goal 2 2007, Real Madrid wire rig shot.

BBC ident: Capturing video of surfers off the coast of Mexico. The camera shot the surfers from the back of a jet ski and the XPe systems transmitted the footage back to a speed boat that had the receiver and recording equipment on board.

 

XPe has also been used during filming of the following:

Harry Potter and the Goblet of Fire. 2005

X-Box commercial. 2006: Used throughout the ‘car chase advert'

Golden Age (Elizabeth 2). 2007:Cate Blanchett, Clive Owen

Star Dust. 2007: Charlie Cox, Claire Danes, Sienna Miller, Michele Pfeiffer, Robert De Niro, Sir Ian McKellen.

Atonement. 2007: Keira Knightly, James McAvoy.

When did you last see your Farther. 2007: Colin Firth, Jim Broadbent

Fred Clause. 2007: Vince Vaughn

Inkheart. 2007: Brendan Fraser, Eliza Bennett

Golden Compass. 2007: Nicole Kidman, Daniel Criag, Dakota Blue Richards
