35mm 3perf impact on super 16?


Alain LeTourneau

Recommended Posts

I'm not currently working in the industry so forgive my questions if they come across as naive or uninformed.

 

I'm uncertain how widely the 3perf format is being used, but with Arri and Aaton offering modifications of their cameras and in some cases pushing for the format, what is the impact going to be on super 16 production? Or will there really be any impact?

3-perf will have a bigger impact on 4-perf than Super-16. Generally a more expensive format does not cut into the usage of a cheaper format, and 3-perf is still more expensive than Super-16.

 

 

 

I was curious as to whether the cost of 3perf is close enough to super 16 to warrant an actual choice between the two formats in terms of stock and lab work?

 

If 4perf is around .50/ft for rawstock and s16 around .32/ft, what's the cost with 3perf?

Wait, 1000' is a 1000'. Rawstock costs are the same. Just getting more for what you pay for, but does this calculate into a savings with stock and lab work?

 

Stock and lab processing & printing are per foot: so you pay the same per 1000 ft whether it's 3perf or 4perf. But you get almost 15 minutes of film instead of 11 minutes, so it's theoretically a 33% saving.

 

Telecine may be charged per foot but often is charged per hour on the machine. No saving there.

 

For TV projects, that's the end of the story. For cinema projects, you have the cost of the 3-perf to 4-perf blow-up to factor in. And costs thereafter (answer print, dupes etc, are all at normal 35mm cost.

 

What 3-perf doesn't offer is the convenience of smaller lighter cameras that you get with 16mm.

35mm 3-perf is not a film format, its a way of capturing more in a smaller space on the 35mm negative.

 

You still have to buy regular 35mm stock, which as said, is about $0.50/foot... It just takes it takes less stock in 3 perf to get as much as you would in 4 perf.

 

3-perf has more to do with Camera Movement than stock, the camera pulls less film through for each frame than in 4 perf, plus it uses the sound area on a regular negative. So you end up using more of the normally waisted real-estate on the stock. HOWEVER: you cant directly print 3-perf or 4 perf S35 (Note: the 3perf format always uses the "Super 35mm" standard). So this means the added expense of an optical step or a Digital Intermediate.

 

3 perf is really kind of like 16mm and Super 16mm, in super 16mm, you are just using the sound track area of the 16mm negative. However, 3 perf adds the twist that it pulls less film through before taking another frame, therein using more rela-estate than normal.

 

Make since? I think I confused myself :blink: ..... Oh well, you get the idea...

You can go to Arri's website and read a complete page and even view an interactive demo of how 3 perf works and saves money, etc... Go here:

www.arri.com, click on "Products", Click "Cameras", again click "Cameras", Choose "Arricam Studio", Go down to the bottom of the page and click on "Camera Technology: 3 perf", then you can read about it, also on that page is a link in the first paragraph to an interactive demo..

 

Have fun!

Thanks Landon, the demo helped tremendously.

Hi,

 

I don't know what you mean "always uses the Super 35 standard". If you mean the lenses are always centered for S35 thats not true. By recentering the lens, many lenses e.g Zeiss 16mm will hit the mirror or cause shaddow problems on cameras such as Arri III's. Other lenses e.g. older Cooke primes and older zoom lenses will vingnette when centered for S35. They were not desinged to cover S35.

 

3 perf can be 3 perf 35 or 3 perf Super 35. The point of 3 perf is to save money. When saving money the latest camera and lenses won't be an option.

 

Super 16, 2 perf, 3 Perf or any Super 35mm format will require the added expense of an optical step or digital Intermediate.

so your telling me you can use 3 perf in regulare 35mm as well as super 35mm? Thats news to me.

 

 

Hi,

 

The film is the same. You can expose and scan any area you want. If shooting 3 perf for 4x3 television you have to loose image from the sides in any case.

 

The standard eyepiece of an Arri II or III does not cover Super 35 but the film gate usually does. Its much cheaper to just modity the gate, ground glass and film advance to 2 or 3 perf. Moving the lens centre may well be possible and changing the viewing system just adds to the cost, and quite possibly limiting choice of lenses.

 

Arri Quotes over 30,000 euro to convert a 435/535.

 

Older cameras have been converted 2 or 3 perf for nearer USD 5000, giving a new lease of life to Ultracams, etc.

Basically, 35mm 4-perf is roughly 4 times more expensive than 16mm including developing costs.

 

3-perf is 3 times more expensive.

 

2-perf is 2 times more expensive.

 

So there is not going to be a 35mm format that's cheaper than 16mm, no matter how you count or do the math. We've all tried 'til we're blue in the face to get producers to rent 35mm gear instead of 16mm and the numbers never add up.

Hi,

 

So I guess 1 perf 4.7:1 could be the way to go LOL!

Landon,

 

If you read and understand the website above, then you will see that ground glasses are available in normal 35 3 perf & Super 35 3 perf. If the measurment is 22mm wide (0.866") its normal and if its 24.9mm wide (0.98") its Super!

Ha, actually that'sone of my old ideas - 1 perf 35mm and then Cinemascope lenses turned 90 degrees so that they compress vertically rather than horizontally. Voila, 2.35:1! I call it

Frischoscope... :D

I had no idea you could do a Regular 35mm 3perf, I thought it had to be Super 35... Unsure why, I guess thats just what I thought...

 

Most people would shoot 3-perf in Full Aperture / Super-35 mode; there's no reason to shoot it optically offset for sound aperture projection since it is not a projection format. Now within the Full Aperture frame, you can compose a variety of aspect ratios.

 

I haven't really heard of 3-perf projects NOT shooting optically centered for Full Aperture / Super-35.

See, at least from what David knows ( which is a LOT), even he dont recall productions using the offcenter method of 3perf...

 

And I cant see why someone would use it? Once you shoot 3 perf, your gonna do a Optical step or a DI, bottom line, so why waist the rest of the "Free" Real-estate on the stock?

 

PS) Almost all standard moderm lenses cover the super-35 frame. At least most all Zeiss's I know if do, and Im sure Panavisions do too...

 

To shoot in Regulare 35mm 3 perf is like buying a lot for your house... the real-estate agent says "I will also throw in an extra acer for free, and you say NO".

 

and of course, super 35mm and full Aperture are pretty close to being the same thing...
