Hi

This is my first post so apologies in advance for anything I do wrong :usd:

Could anybody tell me what the resolution would be if you took a still from a piece of video shot on a RED?

I know this is a really big ask but if somebody could post a still/link to still that would be really helpful as well

Many thanks for you time :bye2:
 
RedAlert exports a 4k tiff image. Not sure there's any better resolution from the image than that.
 
That's as good as a solid DSLR, like the professional models from Canon.

Regards,

Uli
 
In one of yesterday post from Jim, it will be possible to shoot in 4.5K in a very near future.

It is being finalized but I think we have landed on 4480 x 1874.

I recommend talking this feature up to your clients... The chance for them to look at ANY frame of your footage and choose that pic for their poster... That's a pretty awesome feature.

That's not entirely true. It depends on your shutter speed, since if you're shooting for a film like look, it's probably going to create to much motion blur to pull a decent still from anything with any real motion.

The resulting tiff file is 72 dpi.

Sure, but that's only relevant to how an image will size in print. The dpi can be changed to any figure without altering the actual image. 72 dpi is the default Mac screen display size but print resolutions are more like 180 to 300 dpi. A 4.5k image at 300 dpi would print nicely at about 37 cm across.

All I am saying that the tiff you export from RA or RC is a 72 DPI tiff. I have a photographer working with these images now because we are making prints for the production.

The images can be resampled to the resolutions you are describing, but it is not exported from the software.

The size you are describing are correct, but an earlier poster compared a still from RED to a DSR and it is not quite the same as the camera RAW that the DSLR shoots. RED's raw (unsharpened is still amazing) but not quite the same as a DSLR as the images need to be upsampled for print.

If facetmedia got a still file from RedCine of 4096 x 2304 pixels, then it's not terribly smaller than that from a high-end DSLR. The Nikon D3's highest quality output is 4256 x 2832 pixels.

The DPI value has no meaning until it's applied in printing. The 72dpi value is used as a sort of default for computer screens (though many computer screens are better than 72dpi now). Changing the DPI value in Photoshop - as long as you DON'T resample - does not change the image at all, it only changes that number.

I'm using Photoshop. Under the Image:Image Size menu item let's say you change the Resolution (DPI) value to 300 pixels per inch (and make sure the "Resample Image" checkbox is UNchecked). This now means that the print (from the 4096 x 2304 Red Camera output) would be about 13.5" (343mm) wide by 7.5" (190mm) high. At 200 DPI the resultant print would be 20.5" wide. What settings you use depend on how big you want the final print to be OR how fine you want the final print to be (or what your printer requires).

Since 13x7 would probably be too small for a poster you could choose a lower DPI value OR you could up-rez - but you'd have to do the very same thing for the D3 output.

So, Red still image output is about the same resolution as the latest high-end professional DSLRs. The main issue with such stills is going to be the Red's 1/48 second 'shutter speed' causing motion blur, but that applies to pretty much any motion picture camera shooting normal frame rates.

I'm using the D3 as an example. There might be some higher resolution cameras coming out - and there's medium format digital and 4x5 scanning backs, too. And film scans. But the D3 at about USD5000 probably qualifies as a professional camera. :)

quality of the image and the camera is not measured by the # of pixel, and d3 is one of the best cameras out there.
 
I think everyone covered the bases for using a red raw frame to create a still, then go to print. I had to do this with a documentary I shot with the Red. We carefully choose a frame that did not have motion blur and imported it in to photoshop. For the resizing we used Genuine Fractals. I have friends that say everything you need is in Photoshop and within the image sizing box. They may have a point. Genuine Fractals was good. Also, Alien Skin makes a program called Blow Up. These are good programs and may help your particular shot. Whatever works for you. Someone mentioned that there is a monitor that has greater than 72dpi. Who makes it? What dpi does it display? I'm interested. F
 
I've made 24"x36" prints from Red files straight out of RedCine that easily compare with professional 35MM CMOS cameras.

My clients were shocked at the image quality of the prints; one art director in particular all but refused to believe the print was not from a 35MM film still camera.

My prints were pulled on an HP Z3100, 12-pigment printer.

This is a MAJOR selling point for using Red in production vs. 2/3" sensor HD camcorders such as the VariCam. The Panasonic is capable of very beautiful HD images, but the stills can't hold a candle to the Red's; they are OK for small magazine ads, but Red images can be used for giant point of sale display posters.

Good shooting and best regards,

Leo
 
Most monitors these days have greater than 72 PPI*. My cheap 17 inch 1280x1024 LCD is 96 PPI, and 15.4 inch 1920x1200 laptop is ~144 PPI (!). The PPI on CRTs is variable, depending on the resolution you set it to. I think the average now is around 96 PPI.

*PPI (Pixels Per Inch) is preferable to DPI when measuring monitors.
 
just seeing my first prints today.

The files were 4k tiff. Upsampled to 280dpi. Printed at 7x14 and they look


FANTASTIC!!!!
