Time for an update. Actually, we've been intending to kick off with a  video, which is almost done, so look out for that in the next day or  two. In the meantime, I thought I'd address the news that has been  reported about us shooting THE HOBBIT at 48 frames per second,  and explain to you what my thoughts are about this.
We are  indeed shooting at the higher frame rate. The key thing to understand  is that this process requires both shooting and projecting at 48 fps,  rather than the usual 24 fps (films have been shot at 24 frames per  second since the late 1920's). So the result looks like normal speed,  but the image has hugely enhanced clarity and smoothness. Looking at 24  frames every second may seem ok--and we've all seen thousands of films  like this over the last 90 years--but there is often quite a lot of blur  in each frame, during fast movements, and if the camera is moving  around quickly, the image can judder or "strobe."
Shooting  and projecting at 48 fps does a lot to get rid of these issues.  It  looks much more lifelike, and it is much easier to watch, especially in  3-D. We've been watching HOBBIT tests and dailies at 48 fps now for  several months, and we often sit through two hours worth of footage  without getting any eye strain from the 3-D.  It looks great, and we've  actually become used to it now, to the point that other film experiences  look a little primitive. I saw a new movie in the cinema on Sunday and I  kept getting distracted by the juddery panning and blurring. We're  getting spoilt!
 
Originally, 24 fps was chosen based on the  technical requirements of the early sound era. I suspect it was the  minimum speed required to get some audio fidelity out of the first  optical sound tracks. They would have settled on the minimum speed  because of the cost of the film stock. 35mm film is expensive, and the  cost per foot (to buy the negative stock, develop it and print it), has  been a fairly significant part of any film budget.
So we  have lived with 24 fps for 9 decades--not because it's the best film  speed (it's not by any stretch), but because it was the cheapest speed  to achieve basic acceptable results back in 1927 or whenever it was  adopted.
None of this thinking is new.  Doug Trumbull  developed and promoted a 60 frames per second process called ShowScan  about 30 years ago and that looked great. Unfortunately it was  never adopted past theme park use. I imagine the sheer expense of  burning through expensive film stock at the higher speed (you are  charged per foot of film, which is about 18 frames), and the projection  difficulties in cinemas, made it tough to use for "normal" films,  despite looking amazing.  Actually, if anybody has been on the Star  Tours ride at Disneyland, you've experienced the life like quality of 60  frames per second.  Our new King Kong attraction at Universal Studios  also uses 60 fps.
Now that the world's cinemas are moving  towards digital projection, and many films are being shot with digital  cameras, increasing the frame rate becomes much easier.  Most of the  new digital projectors are capable of projecting at 48 fps, with only  the digital servers needing some firmware upgrades.  We tested both 48  fps and 60 fps.  The difference between those speeds is almost  impossible to detect, but the increase in quality over 24 fps is  significant.
Film purists will criticize the lack of blur  and strobing artifacts, but all of our crew--many of whom are film  purists--are now converts.  You get used to this new look very quickly  and it becomes a much more lifelike and comfortable viewing experience.   It's similar to the moment when vinyl records were supplanted by  digital CDs.  There's no doubt in my mind that we're heading towards  movies being shot and projected at higher frame rates.
Warner  Bros. have been very supportive, and allowed us to start shooting THE  HOBBIT at 48 fps, despite there never having been a wide release feature  film filmed at this higher frame rate.  We are hopeful that there will  be enough theaters capable of projecting 48 fps by the time The Hobbit  comes out where we can seriously explore that possibility with Warner  Bros.  However, while it's predicted that there may be over 10,000  screens capable of projecting THE HOBBIT at 48 fps  by our release date in Dec, 2012, we don’t yet know what the reality  will be.  It is a situation we will all be monitoring carefully.  I see  it as a way of future-proofing THE HOBBIT.  Take it from me--if we do  release in 48 fps, those are the cinemas you should watch the movie in.  It will look terrific!
Time to jump in the car and drive to Bag End for the day. Video coming soon!
