well... o.k. maybe not high quality.
but at least descent enough to be used in printed promo material.

Shooting in standard def 720x480
is there a best way to get good stills from video?

last week a prodution company said that the jpegs i sent them
were not good enough....
they said they need at least 300 d.p.i.

i created a still from the timeline
then i exported stills from fcp at highest quality
and while the resolution was 720x 480
the d.p.i was only around 70.

is there a simple upresing possibility?
does it make a difference if i have my pixels set to "square" when
creating the still in fcp?

thanks!
 
well
after looking around a bit
it seems that standard res dv is 72dpi by its very nature...

so do i tell people that getting 300 dpi stills from my footage
is down right impossible?

hmmmm.....

Yes. Get a 8MP camera, or a 6 MP camera, something with megapixels. Take promotional stills of your actors, maybe even re-stage scenes. There's a thread on this somewhere else, but I can't find it right now.
 
as was mentioned by noahk
i'm wondering if anyone who has used photozoom knows....
if it will actually increase dpi?


as in, if i used photozoom to enlarge a still
and then shrunk it back down to original size
would it bump up my dpi? improve my still in any way.
this might have no functional logic.
but
i couldn't find any info about this on their web site
and am waiting for their support answer,
so thought i'd ask.

i have to submit some stills in 24 hours
so just trying to see if it makes cents to
drop $100 on the ap?

thanks
 
DPI refers only to printing- Photozoom will increase the resolution on the screen. It's what you want to make NTSC/DV stills into a quality worth printing.

Any digital image is composed of pixels. The pixels are the small colored square dots that can sometimes be seen when images are enlarged too much, or if you look at your screen close enough. Resolution is the number of pixels in the horizontal direction by the number of pixels in the vertical direction. For example, a picture with 1200 pixels at the horizontal direction and 2100 pixels at the vertical direction would have a resolution of 1200 x 2100 pixels.

As you've probably noticed, nowhere in the above definition it is said what size the pixels are. This is where the DPI comes in. DPI is simply Dots Per Inch. A picture with 100 x 100 resolution would be 1 x 1 inch when printed at 100 DPI, and 100 x 100 inch when printed at 1 DPI!

There's a tradeoff. The bigger the resolution, the bigger the image is. It will take more disk space, occupy more memory when loaded, and will take longer to load or email. On the other hand, the bigger the resolution, the better the image looks when printed.

If you want to display a photo on your computer screen, there is a limit to the number of pixels that can be displayed. Most computer screens have a resolution of 72 dpi, and your inkjet printer will typically print high quality photos at about 300dpi - the quality of most "weekly" type magazines.

thanks for the dpi overview noah.
that was pretty much my understanding too.

i downloaded the photozoom demo and am now a convert.

before that
i also tried fudging with the dpi setting in photoshop
and could actually make a much larger file with a higher dpi,
which when i shrunk it down said it would have an even higher dpi.

as in i took a 720x480 still that was 72 dpi
told photoshop to make it 300 dpi
which would make the whole image huge,
then when i sized it down it said the dpi was like 1200...
but when i looked at the new pic and the old one blown up 600%
there was no difference at all.

with photozoom though the same image rerezed to 300dpi at 600% was very smooth.
now if only the demo version didn't have all those watermarks ....
