Movies in 4k (digital cinema standards)
 
April Showers is shot in 4k using Delsa Digital cameras that are close to $800,000 each. 4k is about four times the resolution of 1080p thus allowing the resolution to create a film-like picture that in most ways looks BETTER than film.

Relative to Blu-ray and home video - its SUCH a pleasure to be able to downconvert from 4k to 1080p (which is how we are editing the film and then resynching up the 4k master) as upconversions never really look THAT good. Downconverting from digital gold like well-shot 4k provides for a pretty special video experience.

Have you seen a movie made in 4k (think the Adam Sandler movie Click on Blu-ray)? Are you ready to give up film? We are.

The Dalsa Origin was the first commercially available digital camera able to capture 4K resolution. It is still the only digital camera capable of capturing 4K resolution uncompressed. Dalsa recently made a deal with the DP of the new James Bond film, Quantum of Solace, to shoot entirely with Dalsa 4K cameras.

4K is definitely the film making trend of the future. Currently about half of all Hollywood feature movies are shot in some form of HD video. (Many use the same HDCAM SR used by television.) Digital video lends itself more readily to computer generated special effects, editing, etc. Film is cumbersome since the film stock has to be processed. Quality is lost when copies are made (each time the film passed thru a lens). Directors like the ability to see immediately the results, as well as the flexibility to shoot the same scene simultaneously from many different angles which would be impractical with film, etc. Before long, I think, film will become an outdated relic of the past.

Adam Sandler's Click was not shot in 4K. It was shot in 1080p using the Sony Varicam line of cameras which was in its infancy when they used it. The same camera package was used in the last three Star Wars films which in my opinion did not look all that great. Dalsa is a native 4K sensor that produces a raw image file that is greater than 1080p and 35mm. It is the ONLY camera that does this as the RED camera is a bit of a cheat and the Viper system is only 2K. 4K raw provides so much "wiggle" room in terms of post that it can not be beat. It's not digital the way many consumers probably think it is. Sure it's a digital image but the optics and shutter are all analog which is why it has such a 35mm feel with more resolution. Other 2K and even faux 4K cameras use a digital shutter or other trickery which is why many purists shun the idea of abandoning 35mm. Optics are just as important as resolution and while other companies jockey for resolution figures Dalsa has the formula right with their Origin II system.

As for down converting to 1080p its an interesting dilemma. As it pertains to our film, much like SD DVD, we'll have to compress things a bit to "fit" everything onto a Blu-ray disc, however, unlike other digital films when then next format (2K or better) hits the consumer market April Showers will be able to be viewed even better or in its native format which is very exciting. That being said even when viewing dailies back in 720p (some of our on set monitors were only 720p) the footage is very impressive. You can always down-convert successfully but up-conversion is a bit of a mixed bag.

Lastly, no film has been shot in its entirety in true 4K except April Showers. Other Dalsa projects have been all 2K and the new James Bond film (also using the Dalsa Origin II) is using them for 2nd unit VFX only. While this is bound to change as the months pass we have no basis of comparison as to what others will do with the format and a true 4K resolution.

My bad.

I misunderstood what I heard at Sony when they launched Blu-ray.

Another 4K feature length movie, "Reach for Me", was recently screened with a 4K projector:

I would sure like to see what one of these movies, shot in 4K, looks like on a 4K projector; but sadly this technology is not available around here, yet.

Fly to the premier and tell EVERYONE you KNOW to go see April Showers. April 2009.
