Canon EOS 5D MKIII - the Swiss Army knife of video cameras

When the Canon 5D MKIII was launched in March 2012 after years of anticipation the reaction of the market was one of slight disappointment or even indignation. The long delay of the launch (caused in part by the tsunami in Japan) had left everybody expecting a camera that would turn the video shooting world on its head and it seemed that this was just an improvement of the MKII.

Or so it seemed.

I used to work for Bernie Ecclestone on Formula One and I had all these ideas for on-screen information we could provide the viewer and asked why we didn't do them for the new season. Mr E's right hand man Eddie Baker replied "Don't add too many new elements in one go, if you do some of the best stuff will go unnoticed." Gradually in the seasons that followed the on-screen graphics were added to, much to the joy of F1 fans.

In a way the Canon 5D MKIII is the same and has lots of features hidden away that are now being revealed both by Canon and others and I see the camera now has three levels of operation. 

Level 1. This is the camera as it comes out of the box (with original firmware). Shooting to the internal cards using H.264 with All-I compression at 90 MB/s or IPB at 31 MB/s the quality was a distinct improvement on the MKII (especially with the improved low light performance). It is used as a B-roll camera in the main and CF cards don't have to be massive or ridiculously fast. It was a camera used to supplement other cameras.

Level 2. Other cameras such as the Panasonic GH3 started to have the ability to output the video signal through the HDMI monitoring port directly to an external recorder like the Atmos Ninja or the Blackmagic Design Hyperdeck Shuttle.

This could also be done with the MKIII but it was not possible to get a clean output - no information over the pictures including the red recording dot. In October 2012 the Magic Lantern team released Alpha 2 which allowed clean out pictures on the HDMI among a host of other improvements. Six months later Canon released a firmware update that allowed the camera to do the same thing - officially. This gave the MKIII the ability to record in 4:2:2 colour space which I won't explain here but gives more flexibility for colour correction. It also meant it is possible to record in less compressed formats such as ProRes 422. With a proper external sound recorder this brought the MKIII up to A-camera status and it became a more practical unit to use for interviews and documentaries.

Level 3. This was the Level people had dreamed of and hoped for when the MKIII was launched. Because the camera is a DSLR is can shoot still pictures in RAW format which gives simply the best recording format available and the dream was to capture this stream of still images and combine them to a video clip in the way that time lapsers have done for years. But it seemed a pipe-dream until Magic Lantern discovered a way of making the camera do it, and do it to internal recording media. They have just announced the possibility to record 14-bit which gives even more colour information to play with. This level goes beyond that of an A-roll camera and becomes a film camera and the results are quite stunning as James Miller's Genesis film displays.

Level 4 would turn it into a EOS 1DX C+ and record 4K RAW to an external record device. This is my dream and a month ago I wouldn't even have mentioned it in public, but now I don't think it is all that fantastical, I'm sure Magic Lantern think the same. Canon have probably got their fingers crossed that no-one ever achieves it.

So the Canon 5D MKIII really is the most flexible camera around and can be used for everything with the possible exceptions of sports and car chases and the analogy with the Swiss Army knife would be complete if there was a flip out bottle opener in the card bay - Canon please work on that. Design supplied.

4K at BVE in London and future proofing

It's been a week since BVE was held at it's new location at Excel in East London and I really enjoyed my two days there, partly for the old colleagues I kept bumping in to, partly because of the new kit I could actually see and touch and partly because of the 4K Cinema presentations. The 3D & 4K Cinema seminars were held in a room about 5 minutes away from the main exhibition so I felt like an orienteerer (or whatever someone who participates in orienteering is called) getting my badge scanned each time I moved between the two locations.

Philip Bloom's excellent presentation "The DSLR journey: from the 5D mkII to the 4K 1DC" was so popular that over 150 people were turned away each day, including me on Tuesday. Philip has not been too positive in the past about 4K's future but one of the reasons I follow him on twitter (@PhilipBloom) is because he is prepared to have his mind changed. He had shot a pop video with Olly Knights on the Canon EOS-1D C the previous week, quickly edited it in Adobe Premiere and Dissolve and produced a 4K ProRes 422 file which the venue guys converted to a DCP to show on the 4K projector at BVE.

The first time he had seen the video in 4K was at rehearsals the previous day, because he, like 99.9% of us working in 4K, doesn't have a 4K monitor (Sony had one on their stand). The only way he could check his pictures at 4K resolution was blowing them up into quarters on his retina screen. I have to say the pictures looked very good and Philip didn't have a massive rig like Canon used on "The Ticket", he just added a TV Logic field monitor:

The video had been shot very quickly and on the hoof, in Philip's words - guerilla filming - which is pretty incredible at 4K, and he managed to turn it around in about 5 days, which makes a nonsense of anyone claiming that shooting 4K at the moment is impractical.

Of course when you are on an island in the Pacific you might need a bit of backup and Sky's Galapagos series was certainly ambitious. 3D on a volcano - tick, and 4K? Why not. The first episode was shown in 4K 3D (or is it 3D 4K) at BVE and we were suitably furnished with dark glasses, which was a little disappointing. But the effect was not. Once you have seen a marine iguana snort out salt in 3D4K there is little that can impress you. I was in row 6 but wanted to be in row minus 3 to really see the crispness of the image but it was still pretty good from 12 metres away.

In an interview with tech radar this week John Cassy, the head of 3D at Sky TV reaffirmed the company's commitment to 3D and claimed that 4K would not be the innovation that replaces 3D but the technology that enhances the format, "There are very clear benefits that 4K gives 3D. The resolution is better and also it could help in glasses-free 3D because it enables that whole resolution and picture quality." He also claims to have seen a glasses free version of 3D but like a News of the World journalist failed to reveal the source.

Canon's 4K camera the C500 is dropping in price but is still at almost £19,000 so it is a hire only beast for now,but the EOS-1D C £10k less than that but still some way off my Christmas list. To me the cameras that will change the broadcast world though are the Sony PMW-F5 and F55 with the AXS-F5 4K recorder (about £16k and £24k respectively) which get round the rolling shutter problem and are "proper cameras" provided you have perfectly flat shoulders. 


There was a lot of talk about how much storage all this 4K material is going to take up but now I wouldn't consider buying less than 3 terabyte external drives (4 TB are out there), 6 times larger than I was buying 2 years ago. With the amount of storage looking like it will shortly double on a hard drive platter I am looking forward to shooting RAW 4K at a price point close to shooting HD now in about 2 years. 

To conclude I will quote John Cassy of Sky again who sums up my opinion on 4K, "We have a watching brief on Ultra HD and 4K. Actually what we have been doing, the Attenborough shows have all been filmed in 4K - and in some cases 5K - so they have been captured and future-proofed in a sense, as far as we can." 

Future proofing avoids obsolescence, if you get it right.
