Resolution difficulties with jit.qt.record OR jit.desktop

icilian fenner's icon

I'm trying to make a high-quality screen capture patch. Unfortunately, when I record or output to jit.pwindow, the resolution is significantly lower than that of my actual computer screen.

I've tried exporting as 'raw' and 'lossless'. Is there something else I'm neglecting? Or has it to do with how my jitter settings are?

Many thanks, Hugh

I can only conclude that it is jit.qt.record that poses the problem, since inspecting the difference in resolution between a jit.window displaying the captured feed and its surrounding graphics shows that there's little loss there.

have you tried using jit.vcr instead of qt record. I use that for a screen capture patch and it works great! also i noticed your qt.record is half the resolution of the desktop. definitely downressing there.

Hey piwolf. Thats seems to be causing the same problem - although it does answer the question as to how to get audio on, which I was going to have to put some thought to later. ;) How differently do I do things to you?

It all works absolutely perfectly at about half the size, but as soon as I specify 640 by 400, which is the size of the area I believe I am sampling (unless I have made a mistake), the resolution becomes about half quality. Is it something about jit.desktop that is transforming the size of my actual desktop for half the area? *strokes chin* I will look in to it.

As for the resolution - did you account for the pack rect 0 0 0 0 function, and the mousestate business? I am trying to track a rectangle of that circumference around the position of my mouse. Have I done that really wrong?:P

fear not! I got it. Here is the final working patch. It *does* work great. Not absolutely flawless, but great.

:D Thankyou!

The problem I think was the "dim" attribute of your [jit.desktop] not matching up to the size stated by the "rect". Open the inspector to have a look.

The problem was that the dim attribute wasn't equal to the size of my actual screen - it appears that the rect attribute can be whatever size you choose for it.

If you're interested, here's the 'perfect' version of the patch ;).
