dpi question

What dpi level does a picture need to be scanned in at to be acceptable on a conventional sized movie theater screen?

Also....If you have a bunch of digital pictures at a relatively low dpi is there any way to boost their resolution? Software? tricks? any way at all?

Thanks
 
Are you going to film out or you just projecting on a digital projector. I usally do it a 300 that is what normal print DPI is. TV usally uses images that are 72 DPI. But FCP will let you use what every you want.

Now if you are going to a film out. I would talk to the lab and see what they recomended. I have hered of some people going as high as 2000+ But I can't say if that would be a good Idea

You can always use Photoshop to boost the DPI. It will not help the way the pic looks
 
I am eventually going to film out so I guess i should qualify the question two ways...

My main concern now is for a trailer that will not be going to a film out. However it may be projected onto a fairly large screen. Won't 300 dpi begin to look a little pixely? Dpi does relate to pixels correct?

As for a film out...and directed towards your photo shop advice.... Are you saying that if I have a photo taken at 300 DPI I could use photoshop to boost the DPI and make the pixels acceptable on a big screen? When you say you can't make the picture look better are you saying that if it is simply a bad picture there is nothing I can do:) Or are you saying that the picture will remain pixeled on a large screen regardless of any photo shop doctoring?

Thanks so much.

DPI does relate to pixels, however, the more DPI, the higher the resolution. Think of this: If you go to close to a stock ticker, it's hard to read, because the dots are spaced out. If you move farther away, it's easier to read, because you percept that the dots are closer together. DPI equals dots per inch, which means how many dots are in an inch on a computer screen. If they're closer packed together, like say 350-400 DPI, you're going to have a great resolution, but if you only have say 100 DPI, your quality is gonna tank. Really tank.

You could always try using genuine fractals to boost the resolution on the pictures. Works a hell of a lot better than photoshops resizing capabilities.
 
What format are you projecting? Because each has it's own pixel size (SD is 720x480). Forget about resolution and care about pixel size. If your picture is larger than your video stream, you're good. No matter what is the size of your projector, it's not going to retrieve pixels that are not in your rendered video.
 
by the way...Super newbie to having to use pictures if you haven't noticed.

First question...Any good tips on finding out more about genuine fractals?...because I'm not sure what that is.

As far as "what format am I using"...I guess I'm not really sure. The trailer is a ten minute promotional thing, set to be shown about a month from now (documentary). The sponsors of the event will probably be providing some type of digital projector with a screen. Just in case I'm totally misunderstanding my footage was shot in 24pa. The pictures were shot on a consumer digital camera on a "consumer" level dpi (don't know exact level)

I understand what you are saying about the format stream ext... but the root of the problem is that I don't understand how adjustable still photo resolution is. I have a ton of these low dpi pictures and their value to the film would be immense. Is the dpi adjustable and will I be able to adjust the cuts to whatever format I may encounter?

If so could you lead me in the right direction?

thank you so much
 
Don't bother with the DPI, that is not your main problem. Check the pixel size of the photos, and since you're projecting a DV stream (that's your format, I take it...), anything that's over 720x480 will be acceptable.

Google will help this.

For your pic question: Go into Photoshop and open up your pic. Go to Image->Image Size and there you will see what the resolution is. The resolution will be at the top in pixels. Find out what it is and if you're still confused, post it here and we can help.
