Welcome to Shoot 3d

Welcome to the shoot3d blog. I hope you find it useful and interesting.
This blog is a bit unusual. I started my research and training as a UK based Stereographer in January 2009. I kept a diary and notes and have only recently started the blog because so many people in the industry wanted to talk to me about 3d and how it works, and how to shoot 3d professionally, that I thought this would be a good thing to do. So I am gradually getting it up to date.
As of the present day - I have just finished shooting sample scenes in 3d for ITV. Including, Emmerdale, Countdown, The JK show and a 3d remake of the title sequence of Coronation Street. I am currently getting ready for an OPEN DAY in assoc. with Procam North - in Manchester in June. (June 18th)
I have just finished quite a complex shoot on 2 REDs... for some stereo footage for a 3d Viral.
Len Gowing Red DoP was officiating, and we had Rob Black and Dr Bernard Harper as Perception Consultants. If you want to get in touch I am one of a very few UK based Commercials Directors shooting 3d for cinema, broadcast, corporate films and virals.

Biology + Psychology + Technology = 3d

The eyes are NOT film cameras. So stop trying to 'think' like a camera when you are trying to visualize a shot or a frame or a scene... This is the first major hurdle when you are a 'died in the wool' time-served 2d director such as me. 13 years in London, 2 years in the States, 6 months in Belfast, 6 months in Cardiff, 4 years in Manchester. That all adds up to 20 years of years 'thinking in 2d'!
To create good watchable stereo 3d that doesn't pull your eyeballs out of their sockets, you cannot rely solely on the Technology. You have to begin with 'how we see' and how the brain uses 'what we see' and combines that information with a whole load of other factors before you even get a camera out of the case...
At this point in the blog I should bring into the frame my new best friends. Dr Bernie Harper and Rob Black. They are from Liverpool University Psychology Dept and they eat, sleep, drink, walk, talk, 3d! They think and communicate only in 3d! It took some adjustment from them to be able to talk to a numpty director like me and start to explain and unravel some of the complexities of stereo 3d. Dr Harper (Bernie to his friends) has been 'doing' 3d research for 10 years and knows more about 3d than is good for the mortal man... Rob Black on the other hand is a Perception Specialist / Consultant and he can show you things in 1d, 2d and 3d that you never knew existed! So Liverpool University, has a world renowned psychology dept. and I would have access to some of their greatest minds to help me learn about 3d. I was psyched
Who was it that said? : "I could teach you everything there is to know about 3d in an afternoon, but it would take you a lifetime to understand it." Sorry if that is a bad quote, but it make the point. It is such a complex area that if you fancy having a go then good luck. Throw yourelf into it and prepare to fail! And understand you cannot 'fix it in post' - It doesn't work like that!

Florette TV Commercial (2d) Feb 2010

I know this is a 3d blog. BUT I have to earn a living while the production community in the North West catches up with the rest of the world! Being a totally unheard of commercials director (not based in London or the South East) is quite liberating in an odd way. You have nothing to prove, no 'reputation' to live up to...and you avoid some of the more incestuous aspects of the business. The other thing is that I am really lucky having a company like The Mob Film Co represent me, because they have world class features directors on their books and so it shows they really have a superb reputation. The top directors in the commercials game can pick and choose who they work for. Ergo, if I am on their books - they must rate my work, because frankly they could pick and choose and boot me off in a instant. The other plus is that I sometimes get to pitch for big national and global brands - like Florette - those lovely 'crispy Salad' people. Their Ads have always been towards the surreal and fun end of the scale and so I guess the agency saw a something in my mad reel that appealed to them! The creative was great fun, and the development process went smoothly. Pre-prod was tight for time, but we got there. The guys at the agency are hilarious - well, they did dream up the whole Crispy Salad idea, and the wonderful world of Florette!
We filmed in Cheshire in one of only four 'Cruck' barns left in the country, a curious 16th century, European looking barn, it was a cold winters morning yet with the lights on and the superb set design by Paul Kondrass it looked amazingly late summer / autumnal! The DoP was Steve Weiser, a master at painting with light, and the shoot went flawlessly. You can see the finished results on TV - the deliciously fruity fruit segments, fresh from Florette! Look out for mad dancing people in a barn chopping fruit with their hands in a fruity ritual...
Directed by yours truly, shot in Arley Hall in Cheshire, edited by Olly at Delicious Post on Wardour Street,
audio at Grand Central and on a screen near you soon! (throughout 2010...).

Motion artefacts / temporal occlusion 101 - JAN 2010

Yesterday, Simon Stappleton from Procam North and I, and Dr Bernie Harper from Liverpool University took two Sony XD cams off the shelf to take a look specifcally at motion issues as I had read some stuff on line about 3d blur and movement and how things can get tricky when shooting movement. I wanted to find out for myself what happened under different circumstances. During my 3d training I have come across loads of people in the film and TV bizz who are full of advice and are quite happy to tell you how it should be done... But then when I asked the questions, I found out that although everyone is ready with advice, NOT MANY have actually shot 3d!(I guess thats just a bit like life...)

We put the cameras onto the prototype Procam SbS Plate, a special plate that Jonathan Bolton at Procam North had engineered so that we could mount ANY camera Side by Side for trials. When you are training it's hard to get access to large mirror rigs, apart from the obvious reasons of cost, ie you need a team of Nasa trained scientists to program it, align it, and 'fly it' for you. Pretty much all of that technology is very expensive to hire, and because 3d is the latest 'in thing' particularly in London and the South east, access is very limited.

Training - is limited and expensive, but if you have the money then Pinewood and Shepperton run 3d training courses. Actually, on the subject of training I was very fortunate in being able to secure an 'Innovation Grant' from the RDA in our region, and that was used to get me superb access to some of the keenest and most intelligent minds on the planet who have been living and breathing 3d for 10 years or more. Now at last the technology is catching up...

For our motion test shoot we shot a variety of settings - interlaced, progressive, different frame rates. We filmed loads of cars driving by and I spent hours in Noise Industries Dashwood Stereo 3d Cinema Toolbox looking at disparities and basically trying to understand what worked, what looked good and what looked bad. Whether or not to track convergence on the passing cars or leave convergence set at an optimal distance. I will talk about convergence in a separate post because it is another of those 'sensitive'' areas in the 3d community, and the idea of this blog is not to cause stress and anger, but to raise the issues for discussion...
In terms of motion - Point One: I would always shoot progressively for motion. Full stop. end. new para.
Yes, you can play with frame rates and electronic shutter speeds - but you must shoot progressively because of how the frames with movement on have motion artefacts when shooting interlaced. You may have seen it yourself in 2d TV - that weird jagged edge where the scan lines have captured slightly different moments in time so a waving hand breaks up across scan lines. If you combine stereo shots with this effect you end up with a mess that the brain can not fuse, so no 3d. Always shoot motion progressively.
Point Two: Your cameras should be synced or 'gen locked' so that each frame is written and captured at the same time - that is to say the beginning of each frame must start at that 1/50th or 1/25th of the second (or 1/60th) and scan each line, both camera's perfectly in sync. Line 1 right eye camera, scans at the same velocity and the identical moment in time as Line 1- left eye camera and so on through the full frame scan.
So Progressive and genlocked / synced. We did try some early days tests with 2 HVR-A1's that were not 'genlockable' but were synced through a dual lanc within 100ms and on the whole the results were not bad. Though we weren't filming anything with much movement - just some stuff around 'sets' for a tv drama, kitchens, living room, that kind of well lit set up in a TV studio. We used a digislate to mark top and bottom of each take to see how the sync help up over time and it was reasonable and useable.
Definitions:Motion artefacts - weird bits of video that are created when the technolgy has to 'predict' what the movement in the frame is - or how the technology sometimes fails to capture the action properly.
Temporal Occlusion - when the differences between the two shots are caused by time, by the the way the 2 cameras have recorded or 'captured' everso slightly different moments in time, and so they don't work in 3d.
My final thoughts - you can shoot on interlaced formats - I use 2 little HD JVC's shooting AVCHDs or MPEG.TS for 'Pre Viz' and ' recce' . They are not locked, not synced and interlaced!
But they show me enough to see what works and what doesn't work...
