See you
again! I’m Ying.
After we
talked about advantages of digital movies in the last few days, of course, now
we will go through the weaknesses of digital movies.
In the hypothetical,
resolution of 35 mm film is better than that of 2K digital movies. 2K
resolution (2048×1080) is only insignificantly over than that of consumer based
1080p HD (1920x1080). Nevertheless, as digital post-production techniques developed
the standard in the early 2000s, the most of movies, whether photographed
digitally or on 35 mm film, have been controlled and ran at the 2K resolution. Furthermore,
4K post production is come to be more popular. Since projectors are substituted with 4K
models, the change in resolution between digital and 35 mm film becomes tiny.
In
addition, digital movies need more bandwidth to support over domestic 'HD'
which is what makes the change in quality. For example, Blu-ray color encoding
4:2:0 48MB/S MAX data rate, DCI D-Cinema 4:4:4 250MB/S 2D/3D, 500MB/S HFR3D.
Therefore, each pixel has greater detail per frame.
On the
other hand, the initial costs for converting theatres to digital are quit high:
$100,000 per screen, on average. Theatres are unwilling to change without a
cost-sharing arrangement with film distributors. A solution is a temporary
Virtual Print Fee system, where the distributor (who saves the money of
producing and transporting a film print) pays a fee per copy to help finance
the digital systems of the theatres.
