Does anyone have any ideas about capturing full-res stills from a Blue-ray disc?

Seems to me the capturing options should be about the same as for regular DVD (print screen and crop, the little camera icon in Power DVD, etc.) but I could be wrong...

Recent versions of VLC have an excellent frame grabber that follows deinterlace settings.

accidentally came across a one day free offer of Topaz Moment (like divx had some time ago)-downloaded and checked it out-allows use of some post processing and has a super resolution option while capturing-seems to be based on MPC-list price $39.99
I got it free-so i like it. Handles almost all formats.

PrintScreen and PowerDVD won't make a still capture at full resolution. They'll only capture at 72 DPI screen resolution. When playing regular DVD's, this isn't a problem. You can get a still capture through Blue-Ray through Print Screen, but it's at the lowest-resolution possible (72 dpi).
Blu-Ray is much higher than regular DVD's, and so I was hoping to get a higher resolution still capture. I think I'll try out Topaz Moment. It looks like it might do exactly what I want.

Here is a VLC cap from 1080i using single field quarter resolution 960x540 "discard" mode under "video" "deinterlace". You can cap at 1920x1080 using any of the other deinterlace methods.
Here is another off air cap at 1280x720p.
Click on picture for full resolution window.
VLC is very easy and versatile for screen cap. The only things it won't do are frame average or multiframe cap but those can be done in your editor.

PrintScreen will capture at whatever resolution the screen is displaying. If the screen is 640 X 480, that's what it captures. I just now pressed it and pasted the result in IrfanView and sure enough, it pasted 2304 X 800 (the combined resolution of my two side by side screens). Therefore, if you are displaying BlueRay at full resolution (whatever X 1080), the screen cap will be full resolution. Screens don't even have 'DPI'...Just dots.

Of course screens have DPI. It's related to the size of your monitor and your current resolution settings. If you have a 14.5" x 12" of actual screen space, and your resolution is 800 x 600, then your DPI is 55 DPI (dots per inch of monitor space). At 1024 resolution with 14.5" of screen space, your DPI is rougly 72 DPI. This is exactly why increasing your resolution makes everything smaller. The "dots" get smaller increasing your resolution and increasing your DPI. The Inch portion is your physical monitor size. And, because everything in the computer is related to pixels not true inches, everything (windows, text ,icons, images, etc) get smaller visibly.
In print, the Inch portion represents one inch of print space and how many dots got printed onto the paper in that inch. Monitor resolution is no different, except dots=pixels and pixel size can be dynamically adjusted with your resolution.

Well yes, however the DPI of the screen is irrelevant to the capture. I should have said 'Sreen CAPTURES don't even have 'DPI'...'

Hi, I have read through the thread and seems like image grabber 2 is the choice to capture screenshot for newbie. I have about 300 wmv files (about 60 mins each) that i need to capture a screenshot about every 10 mins. Is there a software that I can use to batch this instead of clicking/capturing 1 video at a time? How about a command line tool to does that? Also, for getting the exact length of a wmv file, I know media info does that, again.. is there a command line app that I can do that with?
Thanks a bunch

I thought I would add to this thread in that I hadn't seen mentioned that Media Player Classic does very good contact sheets. Starting with version 6.4.9.0, load a vid, goto file and click save thumbnails. The resulting save as screen is pretty self explanatory.

You're mistaken.
BMP is an uncompressed image. JPEG is compressed.
The BMP is not worse than the JPEG, but neither is a JPEG necessarily worse than a BMP (if compressed well).
