Hi guys, what’s the best way to get a hi-res image from a DVD? Obviously pausing and taking a screenshot is not going to give me any more than 72 ppi so I wondered whether anyone here had advice on how to get a better quality grab.

It’s currently on my hard-drive saved as Video_TS components and my default player is VLC. It does have a snapshot facility although it’s not especially great. I am using Vista and CS3.

Thanks in advance for any input.

I did try to import the mgp into PS via File/Import/Video Frames to Layers but got the error "cannot be opened". I wonder exactly what sort of mpg file Pshop CAN open?

In the end, I played the video through VLC and used Corel Capture to take 600 dpi screen shots. My images came out at 1.2 mb each. Oddly though, Vista cannot display these thumbnails.

Photoship is a graphic editor *not* graphic viewer so it won’t treat all graphic formats the same. IOW, unlike graphic viewer you can name or rename any format to any extension you wish and it should be able to open 99-100% of the time, but not with Photoshop (or it would do the opposite way or it won’t open 99-100% of the time).

About the 600-PPI, I don’t have much experience with screenshot (I do screencapture now and then but for other thing so I don’t pay or need hi-rez) I don’t have much experience to share. But I am guessing the 600-PPI would be better than 72-PPI (or lower than 600-PPI), but I am pretty sure 600-PPI is just part of the whole thing, or the quality may also depend on the Screen Size (just guessing). I mean screencapturing a full 20" screen at 600-PPI probably have more resolution than 600-PPI of 5" screen (but I may be wrong).

Oops! I re-read the message and you mention "MPG" which is VIDEO format *not* graphic format (I misread as JPG or BMP) and that ain’t odd for Vista or Photoshop to open or displaying the thumbnail, cuz thumbnail is pretty much mean index of GRAPHIC not video. And I have no idea how you get the 600-DPI stuff.

This is what you need to do, go out to find a util to make a snapshot of the screen and save to JPG or BMP. I have some but I can’t remember the name to give you more hint, and I know some DVD player programs have built-in the option to do screencapture and save to JPG and BMP.

DVD movies are low resolution. What you see is what you get. That’s all there is; they do not contain high resolution images.

You can’t bump the actual rez, but there are ways to improve the appearance of the image considerably. Averaging frames to get rid of noise. Masking and/or cloning material from adjacent frames to minimize motion blur.

Assuming a relatively static image frame to frame. And even then, the amount of image information is still limited to the (low) resolution of the recorded image itself; ain’t no way ’round that.

Agreed. A standard PAL TV frame is 720 x 576 pixels, and I think NTSC is even smaller.

No way to make it better.

Au contraire, mon frere. There are any number of tricks that can be used to improve a video image, including the ones I mentioned already, here are a couple more:

1) if the image is static, combine several frames as layers, with the transparency of each additional layer set to 50 percent, 25 percent, 12 percent, and so one.

2) if the image pans around, combine the images as a mosaic to create a mini panorama. This will, indeed, give you a higher resolution image than the original. This is particularly interesting for animations, and certain matte paintings, where the entire original background can be recreated.

3) for interlaced images, use a mask of alternating black and white lines to get rid of motion artifacts from adjacent frames.

3) don’t forget color and contrast – use the full range from black and white, and keep the colors saturated to increase the snap of the image.

4) sharpening – convert to Lab and sharpen the L channel only. Blur the a and b channels slightly to get rid of color artifacting.

5) Video pixels are not square, and there are a number of ways to improve your images if you take this into account. When sharpening, for example, stretch the image vertically, apply your sharpening, and then compress the image back to its original aspect ratio.
