Print images are a much higher resolution than video. It's just the nature of the medium.

You'll see this also if you download a logo from a web site and print it out. Web graphics are only about 72 pixels per inch, while print is between 200 and 300 pixels per inch.

Believe it or not, that big picture on your TV is only 720x480 pixels (Which is why, as TVs have gotten larger, we've been moving toward hi-def video).

A 720x480 image at 300 pixels per inch? That's only about 2-1/2 x 1-1/2 inches! Even at 200 pixels per inch, it's only about 3-1/2 x 2-1/4 inches.

Does that make sense?

I don't know why a picture that small looks so detailed on a big TV screen. Maybe it's because we're usually sitting several feet away from it.

Sit as close to your TV as you usually hold a book from your face and it will likely look pretty fuzzy.

That's because TVs resize the image to fill up their whole screen. They also apply an aspect ratio change, so for example, a widescreen 720x480 DVD image, will get stretched to about 852x480 while playing.

Well if I make an image say 2 inch x 1. inch and put it on a TV it will look not that good even if I make it 300 DPi

But if I make an image 720 Pix x 480 pix and put it on a TV it looks good.

I gess I am not getting something that os going on with inchs and Pix?

2 inches by 1 inch on a generic 17" SXGA monitor is about 320x150, not 720x480. If you're making that 2x1 inches image on a paper, and then you scan that paper, it will depend in which resolution you scan it.

"Inches" mean nothing.
"dpi" means nothing.
The only thing that makes a difference is pixel dimensions.
Make your still's pixel dimensions about twice those of your project format.
That will give some wiggle room for cropping and panning.
This is not rocket science. The things you thought were important in printing are of no concern whatsoever in NLE.

ok I use Movie studio 8. and say I have a video in my timeline from say my Camara.

My Camara also takes video at 720 x 480 I get this this is the standard even if it is Widescreen or 4"3 it will be the ratio that makes it look that way I get this.

But if I use Movie studio to take a snapshot of the video in the timeline.

Then I print it out it is very very small.
Sould it not if anything fill the page up?

I know the printer prints in Dots Per Inch but still would it not convert it to be very big?

How can sutch a small image look so good even on a 60 inch TV?

Like musicvid said, inches and dpi mean nothing.

When you capture a video frame, it's 720x480, when when it's displayed on your PC monitor at 72dpi, your frame will be 10-inches by 6.6-inches. But when you print it at 300 dpi (ppi), the frame will be 2.4-inches by 1.6 inches.

The math doesn't allow it to "fill the page up" when printed.

Why does a 720x480 image look so good on a 60-inch TV? Because that TV [most likely] has a resolution of 1920x1080 so the TV "will always automatically convert or scale the video signal to fit the screen's native resolution."
