    Frame Rates Question

    in Super-8

    Posted

    Hello,

     

    another thing is the better sound quality @24fps!

    If the film runs "faster" you can use more magnetic tape on the film at the same time which means you can use a bigger sound spectrum.

    With 18fps around 70-10.000 Hz and with 24fps around 70-12.000 Hz

     

    greetings,

    Animorphic telecine?

    in Super-8

    Posted

    Hello!

     

    Now, which anamorphic lens is best suited for getting close to 16:9? Are they all super wide?

    You can use one with factor of 1.33, it turns your 4:3 frame to 1.772:1 very close to the 16:9 format (1.778:1).

    There are different compression factors for anamorpic attachments like 1.25, 1.33, 1.42, 1.5, 1.75 or 2.0

     

    Based on the 4:3 Frame:

    1.25 --> 1.66:1

    1.33 --> 1.77:1

    1.42 --> 1.89:1

    1.5 --> 2:1

    2.0 --> 2.66:1

    internal and external Filters

    Hello,

     

    @Bernie: Thank you for your postings too!

     

    ...On many cameras, nothing replaces it, and nobody ever worried about what impact that had on back focus until now.

    A lot of Super-8 users care about if the back focus is as good as possible. The discussion about this filter-remove-question is very old and not a result of this thread ;-)

    Maybe it is also a question why or for what somebody is using the Super-8 format.

     

    The only thing I was trying to say was that many Super8 cameras do not have a clear or UV filter to offset the theoretical shift in focus.

    And the only thing I was trying to say was that some super 8 cameras have maybe a backfocus problem after removing the built in filters. Maybe, someone here did not know this and now, thinks about checking the camera befor using it for professional shootings. Thats all why i said here something about it.

     

    The initial question was:

    "...should we ask the Tech to remove the internal filter and then go with an external one. I'm assuming correctly that this flimsy pieces of plastic can or could deteoriate, get damaged?..."

    My answer:

    Although I see no point in it, removing it will do no harm. All you really have to do is flip the switch from the little sun to the little lightbulb. Doing so removes the filter from the lightpath. On many cameras, nothing replaces it, and nobody ever worried about what impact that had on back focus until now.

    My answer:

    I think it is better to remove dusty old filters and shoot the next holiday home movie with (maybe) little back focus problem and filters in front of the lens than to shoot with dirty old filters inside the camera.

    But, if you want to use the Super-8 Medium for professional work, why not optimize all you can?

     

    Which means:

    - Use one of the better Super-8 cameras (Leicina, Beaulieu, Nikon, Nizo, etc.), think about the typ of lens and mounts

    - Find an professional camera technician for a complete service check-up

    - optimize the camera: remove internal filters (Beaulieu 4008, maybe other brands too?!), use sync options for stable 24 or 25 frames, use the FrameMaster to compensate a little the bad cartridge pressure plate

    - think about using digital stabilization in post production

    - shoot camera tests

    - etc.

    I read an article about an S8 filmmaker that used digital stabilization in post production, rather than a hardware solution like the Frame Master. Have any of you tried this?

     

    I never used digital stabilization in post production on my Super-8 projects, for me it is too expensive ;)

     

    Franka Potente used the SMOKE system in her movie called

    Der die Tollkirsche ausgräbt to stabilize the scanned Kodak Vision2. This movie is complete shot on super-8, after the DI process printed to 35mm for theatre release by an ARRI-Laser system.

    By the way, the DoP was Frank Griebe who shot Perfume: The Story of a Murderer or Lola rennt

     

    Link to the movie: http://www.imdb.com/title/tt0496272/

    There is an article about Tollkirsche in the german edition of schmalfilm 3/2006 which describes in detail the workflow.

     

    If i can choose, i would use all possible systems i can get to stabilize the film when shooting on S8mm!

    internal and external Filters

    Hello Tom!

     

    The filter is not an optical element. It does nothing more than alter the color of light passing through it.

    But not if the filter is inside the Flange Focal Depth, if this is the case, the filter IS relevant and changes the definition of this because it changes the standart c-mount flange focal depth (in case of the Beaulieu 4008).

     

    The built in UV-clear filter is there because something must compensate the optical distance like the 85 filter when you shoot tungsten (there is no other logical reason for this UV filter on this place).

    The modification (removing the filters and re-adjust the backfocus of the camera body) is done by camera technicians since the mid of 1970. In germany this cameras have the added word "Pro".

    As i know, Beaulieu stopped using built-in filters on the higher models like the 6009 to 9008 because of this, you have to filter in front of the lens.

     

    Please let me qote a sentence of Mr. Douglas C. Hart (Author of The Camera Assistant, page 256):

    The Flange Focal Depth is the distance between the rear mounting flange of a lens and the film plane. This distance varies from camera system to camera system, but is a specific critical distance, measured in ten-thousendths of an inch.

    I dont know exactly how thick a wratten-85 filter is, i think something between 0,01 and 0,1 mm - and then it counts in the world of "ten-thousendths of an inch"?!?

    Hello,

     

    have polish surface on perimeter and black cavity inside

     

    i think you discribe here (better) what i mean with "Metal-blank, not black (with vertical "reliefs")" :rolleyes:

     

    Today, i asked Mr. Klose why the FrameMaster is chrome silver and not black.

    He said, a chrome silver pressure plate is much more slippery than any kind of black painted plates, that is the reason why it is made by brazen chrome.

    I'm not sure I follow you. What is out of adjustment? Optical? What exactly does that mean? How do you know this? Seems to me all you are doing is taking the filter inside out and replacing it with an external filter.

    +filter-filter = -filter+filter. Simple algebra.

     

    Hi,

     

    first, i forgot to wrote that this is guilty for the Beaulieu 4008 and maybe other S-8mm cameras with changeable lenses, sorry for that!

     

    You are right that it makes sense to remove the old wratten filter because this 20-30 year old filter losts his optical quality most of the time.

     

    I try to explain it for the Beaulieu 4008. Inside the camera body are two filters, one is the wratten (85) filter for daylight, the other one is a clear UV filter for tungsten.

    if you look through the viewfinder, you cannot see a switch to "red" when you use the built in wratten because the filter effect happens after the viewfinder take-off.

    The "optical-system" inside the camera is calculated inclusiv this little, thin filter (UV or 85). If you only remove the built in 85 filter, these minimum millimeters are gone and the back focus is not exact anymore. This will be no problem for long telephoto shots with f11 or f22 but using short 4, 6 or 8mm at f1.8 you can get a problem here!

    This is also the reason why it is a difference to filter in front of a zoom lense or after the last element of the zoom inside the "flange focal depth".

    I hope that makes sense to you?!

     

    As far as i know the Leicina also has the two built in filters, but i dont know 100% for sure.

     

    cheers,

    André

    Hello!

     

    please keep in mind that if you remove the neutral and wratten filter, the original optical setup inside the camera has changed! After removing the filter you have to re-adjust the camera optical system.

    If not (only popped out the filter), you loose image quality!

    Hello!

     

    I checked some pressure plates:

    Metal-blank, not black (with vertical "reliefs"):

    - ARRI-SR

    - ARRICAM

    - Cinema Products GSMO 61M

    - Aaton XTR

     

    Black (no structur):

    - Arriflex 16m

     

     

    i am still thinking about it, why black or not. :blink:

    Hello,

     

    i worked with the old Leica Disto Lite 5 and its a very exact distancemeter, nice and fast to handle. The only bad thing for the camera assistent working with the Disto Lite 5 it that it makes a beep-noise when you press the measure button. I wrote a little manual to modify this device to stop beeping, maybe its helpful for somebody? Its written in german but the pictures speak for themselves:

    Hello!

     

    Maybe this setup is good for you (its calculatet for camera+lens around 2,5 kg):

     

    Tripod: Manfrotto Basic 055DB

    http://www.manfrotto.com/Jahia/site/manfro...=69&child=2

    Head: Manfrotto MA 804RC2

    http://www.manfrotto.com/Jahia/site/manfro...=81&child=1

    Head: if you want to pan while shooting: Manfrotto 700RC2

    http://www.manfrotto.com/Jahia/site/manfro...=86&child=1

     

    Price in Germany/Euros:

    055DB = 82,70 ?

    MA 804RC2 = 72 ?

    700RC2= 85 ?

     

    If you need some Rods and Mattebox, etc. that has to be counted extra.

     

    Good luck,

    Pressure Plate Device for S8

    At 239 Euros plus shipping for 1000 ft. of film it comes to about $15 per 50' roll excluding the 1000 foot roll shipping. Then load your own cartridge with the metal plate. Or buy 50' cart. of film direct from Kodak and use you own reuseable plate. Seems like the metal plate in Kodaks cart. is the better deal all around. Am I missing something?

     

    Yes, K40 in Super-8 cartridges is not longer produced by Kodak :( !

    The only way to use this emulsion in the super8 format is to shoot in DS8 or use offers like the one from Wittner.

     

    But you can calculate it against the new Ektachrome 64T:

    If you buy 1000ft in 50ft cartridges (Wittner price), you have to pay US$ 9,34 against US$ 9 for 50ft K40 (Witter price, buying 1000ft and reloud it yourself).

    If the Ektachrome emulsion is ok for you, take it and dont stress yourself with loading 20 cartridges in the dark room :ph34r:

     

    You can use the FrameMaster with any cartridge (as i know), but not with the russian one with another metal pressure-plate inside.

    Hello!

     

    The Frame Master is invented and built by GK-Film GmbH

    (Mr. Gottfried Klose). You can find all information about this Pressure Plate for Super-8 on his website in english:

    http://www.englisch.film-super8.de/

     

    Here you can see a demo video which shows the result by using thie Frame Master:

    http://www.englisch.film-super8.de/3_andru.../demovideo.html

     

    The old super-8 problem is the cheap plastic pressure plate inside the cartridge which causes bad picture steadiness and sometimes out of focus pictures. If you put the Frame Master in the cartridge, you get a very steady image, much better than without it! You can change it very quick from one cartridge to another.

    On the GK-Film website you can find an english Frame Master manual pdf-file:

    http://www.englisch.film-super8.de/3_andru...atte/manual.pdf

     

    You can buy it on GK-Film website for 128 Euro.

    The same original Frame Master is sold by ANDEC Filmtechnik:

    http://www.andecfilm.de/en/e_s8_pressureplate.htm

    Price here is 120 Euro inclusive shipping to the US

     

    Film stock from 50f to 1000f (depends on which stock) are availible here:

    Reloadable cartridges:

    Wittner Cinetec Germany

    http://www.wittner-kinotechnik.de/katalog/...mm/s8_meter.php (bottom of page)

    - Plastic cartridge with plastic pressure plate, you can use this type with the Frame Master!

     

    Olex Kalynychenko (Ukraine ?)

    - Plastic cartridge with metal pressure plate (you can see it on the pictures linked 4 postings above by Mr. Rodolfo Guzmán Huerta)

    Attention: you cannot use this typ of cartridge with the Frame Master!

     

     

    I think this piece of metal is worth the money and now, Super-8 is really near the stable pictures of Double-Super 8!

    André
