Print Screen

Postby post-it » Sat Sep 20, 2003 7:56 pm

This is a fuction form the TSR coded day's of uSoft and has never been updated!

The original concept was to capture everything on the Display Screen, but that
required a non-moving image ( like a spread sheet or picture! )

To get this function to work properly, today, you need to:
1) pause the DVD at the picture you want to grab.
2) press Print Screen twice.
3) open your Paint program ( if its not already opened )
4) Paste the picture to your Paint program ( yes it will be black! )
5) go back to your paused DVD picture.
6) press Print Screen
7) ^_^ bingo - there it is ^_^

The reason for the delay is the TSR Memory Usage and the failure of the TSR
to pre-clean "that" location of its memory first ( programmers oversite )
and by doing the Print Screen - Paste - Print Screen twice you have corrected
an error that MicroSoft has not deemed worthy of updating.

TRS's were very popular nine years ago and so were Batch files - why this error
never got updated? - who knows ^^;;;; . . this 7 step method works /fin

You can also rip the specific vob, and then open it in vdub and rock and roll from there with the "Save Image"command.

madmag9999: You can't do a screen grab because of video acceleration. You could try what Dannywilson said, or try turning off hardware graphics acceleration as described here:

Well, I've always used the 'Capture' function of PowerDVD. Works like a charm!

If you have built your computer correctly then the "Print Screen" button should work flawlessly - I've used it under Windows and Lenux; so I know it works when the computers they have built done correctly ^^

No, it shouldn't, unless you've got a video card that's 10 years old and doesn't use hardware video acceleration for all video playback.

Unless you're using (1) special drivers, (2) a different capture program OTHER than the default Windows facility, or (3) no hardware acceleration, PrintScreen won't do anything.

None of those cases are the most common case, so you don't have much of an argument when saying "but it works in a properly configured system!" unless you want to prove that MOST computers are misconfigured (and then you'd just have a mess on your hands).

Windows captures via the GDI. (On a GNU/Linux machine, you can configure the same behavior.) The problem is that 99% of modern video cards do NOT use the GDI for video playback as it's just too slow; they take a different, more direct path.

And I know for a fact that "regular" screen captures don't work to capture content being played using XFree86's Xv extension, on a FreeBSD, GNU/Linux, or any other UNIX installation. (They sometimes work when you use OpenGL acceleration, but most people don't, since Xv is usually superior).

Might work with some other X-server, but not the most common one.

Did you read my post?

More importantly, what do all those screenshots and subbing have to do with anything?

I said that OpenGL output can sometimes be captured using "regular" screenshot methods on XFree86 -- a very specific case that I threw in for the heck of it. However most hardware-accelerated video playback is done via hardware overlaying and cannot be captured using said "regular" methods. Programs like SmartCapture can capture that data, but not Windows' built-in screenshot facility, which is what you said would work.
