I previously posted my experience mixing in the 5.1 format so I thought I'd mention
mastering my movie, "What Really Frightens You" in high definition for those who
are interested in the technical process of releasing a film on video.
I shot the film in 35mm and it's in four reels (80 minutes) plus a 1 1/2 minute trailer.
The film was negative matched so it's complete as I wanted it although many producers
don't go this route anymore.
There are two ways of mastering a movie in high definition.
One method is to digitally scan in each frame of the entire feature into a computer at
either 2K or 4K. Then color correct it and output it to a high definition tape. They now
have a videotape that contains 8 channels (previous HD tapes only had four) so a producer
can input the 5.1 mix and 2 channel stereo directly onto the master video in HD. The tape
is HD SR 4RR 1080p. Previously only the 2 channel stereo and M & E would fit onto the tape
and the producer would have to supply the 5.1 mix as a separate CD-ROM which would be
played in synch when the film was authored for release so this new tape is much better and
doesn't run the risk of drifting out of synch. The advantage of this method of mastering is
if the movie is very old and a bit shrunken, the splices of the negative might jump at each
cut. The computer can stabilize the image since each frame is a separate entity. You can
also clone out scratches, dust, dirt, fill in missing frames by sampling previous ones and other corrections since each frame is a separate image in the program. The disadvantage
of this method is the cost. It's about $10,000 for a 80 minute feature or
more if a lot of digital fix ups are required. But, for an aging worn out negative you can
make it look brand new providing you can afford the expense.
The other way is what I utilized which was to master the film on a Spirit 4K telecine which
plays the negative continuously through sprockets and rollers. Rather than scan it in a frame at a time, the reel just plays as if it was being shown in a theater and the telecine
tapes it. The process involves first going through the entire negative on a shot by shot (instead of frame by frame) basis in the telecine (which is similar to a projector and has
a lens that inputs the film) and adjusting the color so it matches. Then the negative is cleaned and it's transferred to tape with the proper color timing on a reel by reel basis
which has already been pre-programed from the first shot to the last, leaving out the leaders at the head and tail of each reel and making it a continous movie. It's considerably cheaper this way and ran me $300 per hour. I was able to transfer my 80 minute feature and trailer in nine hours. After transferring the image, it went to the sound department to dub in the 5.1 and 2 channel stereo tracks in the eight audio tracks available. The M&E will be on a separate CD rom for foreign release (both 5.1 and 2 channel but without the center channel dialogue). This method will only work with brand new features that aren't shrunken or damaged because there are limits what can be done in terms of stabilizing
a shrunken frame or eliminating dirt and dust. If the film is very worn, it should be done in the computer frame by frame method.
What was quite interesting was how the Spirit telecine was set up. The colorist, Jane, kept the room in darkness except for the control panel and adjusted the color, contrast and brightness on a 25 foot HD monitor according to my specifications. However, next to the screen was a computer monitor that took a sample of each frame and retained the color correction in a succession of tiny thumbnail images. So when we were working on another reel that had the same location that was used in a previous reel, she could go through the computer thumbnails of each scene, click it on and the new scene would automatically match the early sequence in the same location. For example, the publisher's office is
used in three scenes in my film contained on reels #1, #2 and #3. So after color correcting the scene in Reel #1, we could automatically correct the later scenes in #2 and #3 by just clicking on the color corrections from Reel #1. This was much easier than color correction on film for a print where you had to physically put up the other reels and manually rewind it down to the scene and check the timing numbers. This method ensured that the timing would be identical from scene to scene and shot
to shot.
My final transfer really looked awesome. Because I used a lot of light on set and a stylish color design which replicated the Technicolor Hammer horror thrillers of the sixties, my movie is razor sharp, incredibly fine grain and detailed with vibrant primary colors and fleshtones. It really paid off shooting at a high f stop (5.6) compared to some cinematographers like Gordon Willis ("The Godfather") who shot with very little light and the camera lens wide open at f 2. There is no grain at all in my film and the HD master looks better than a camera negative release print because it's not 'first generation' but the actual generation of the image that was exposed in the camera.
So at this point in time I would still strongly advocate shooting in 35mm rather than digitally
and then transferring the cut camera negative directly to 4K HD. I think it looks better in
some respects than a Technicolor print. Also, I have the advantage of being able to transfer
the negative to some other future higher definition format. 35mm emulsion is very fine grain
with a lot of detail. If I shot digitally I'd be stuck with the limitations of that pixel count and
couldn't generate the same quality at a later date. Plus digital isn't permanent. Whether it's
videotape or a computer disc or hard drive it's subject to long term degradation if not complete erasure. 35mm negative is a hard copy of the images and far more permanent for the long run.
As a footnote, some producers are not actually cutting the 35mm together into reels
and just putting up the dailies and taping the shots they used and making their HD
master that way. This is really penny wise and pound foolish because then the original
movie will be contained on hundreds of little reels and if they need to make a higher
definition version in the future, they will have to tape each shot one at a time from
the original camera rolls. It makes much more sense to have a completed cut negative
will all the shots you selected on each reel which you can then master to HD or make
a film print from. Unfortunately, since so few people are actually creating a final cut
camera negative now, all of the negative matchers have folded in NYC. I had to hire
a free lance cutter to assemble and splice my negative this time. I might have to negative
match my next movie personally. Curiously, Jane, the colorist asked why I bothered to
cut the negative together into a continuous feature since she was used to taping each
individual shot from a separate camera roll for other clients. But I'm one of those people
that doesn't 'follow the current trend'...especially if the current trend doesn't make
fiscal sense to me. Most producers just do what everyone else is doing at any given
time and then worry about the expense or problems later.
