Hi,
I need some one who has good experience.
I'm doing a scan of a 35mm trailer for my friend,
there's no Oneg to work with.

Can someone check my forumala.
MTFlens x MTFnegative x MTFi.p x MTFo.p x MTFprint
Based on late 90's stock's and equipment

I estimate the resolution would be around 1k or 2k
would you get a HD scan or 2k scan

The Format is:
35mm 4 perf
Aspect ratio: 2.35
Print year: 1997

I'm a little confused by your posting. Is this a full height anamorphic scope print? It makes a big difference.

As far as resolution goes the difference between HD and 2k is VERY minimal in theory but maybe not so minimal if your print is a full height anamorphic scope print.

Having said that the scan process might be quite different between the 2k scanner and the HD scanner unless you are looking at getting them scanned on the same system?

love

Freya

Hi Freya as far as I've been told it's not scope. So it would look similar to this image

Black bars inside of each 4perf frame.

Because HD would be 1920x850~
2k should be around 2100x1080

I would get 2k or higher scan for the width; 2048 by "X". X being what ever your frame height is like Freya stated, matted or full frame, scan it all. I would get the highest res you can afford. Also get an IR flash, again if you can afford it.

Well theres an interesting discussion about continuous scanners / telecine scanners here in the context you are talking about:

http://www.cinematog...on_a_spirit.htm

However I'm guessing you are talking about scans on film scanners like arri scan etc that have the advantage of pin registered transports? I would check that you would be definitely getting 2100x1080 in the context you are talking about and that it isn't also a crop.

Also it's worth remembering the other issues with various kinds of scanning, such as whether it is a pin registered scan or the kind of thing discussed in the above discussion.

Hope that's useful info.

Another thing to think about...

I'm not sure what is available out there for a reasonable price these days, but if you could maybe get a 2k scan on a 4k or 6k scanner so that you get a full frame 2k anamorphic scan (2048×1556) as your completed files, that could be kind of neat depending on what you are up to! ;)

Not sure at all how that would be in practice tho.

I'm trying to figure out how or why someone made a flat print with a 2.35 letterbox in it, rather than a scope print. Unless it was shot with a 2.35 hard matte in-camera (unlikely) that means that it went through an optical printer and probably through an IP/IN step to add those borders. -- Oh, I see that you said it was a trailer, then it makes sense to letterbox it if it ran before a flat movie.
