Hi

I'm trying to crop out an area of high resolution images (e.g. HD).

Unfortunately when I load the images into VDub the GUI for cropping goes off the edge of the screen and I can't drag the window to see the bottom.

Does anyone have an easy way to make the GUI preview smaller just so I can adjust the cropping ? I can do it manually using an AviSynth script but using VDub with a GUI is more natural.

Thanks in advance.

You can manually resize the image in the main window with mouse, just as every window :)
Set the cropping values and check in the main window if the cropping is correct.

The image is much larger than the screen size so it's not possible to do that.

Hi!

Have you tried increasing your desktop resolution?

Have you tried increasing your desktop resolution?Some of us aren't blessed with the ability to size to >1920x1080!

I have had the same problem as lqy. Dunno how to solve. :confused:

Try this: in the filter chain, set the 2:1 reduction (no matter which one).
Enable the preview for the output, and set the vertical mode display, swapping the output image UP.
Now in the main window you can see the preview with half resolution.
RESIZE the preview image at HALF OR LESS the dimensions.
Remove the 2:1 reduction filter from the filter chain.
This must work. You'll see the preview with reduced resolution, but you could be able to check if the cropping is correct.

Mpeg2Source("1920x1080.d2v")

return stackhorizontal( crop(0,0,512,512), crop(width-512,height-512,512,512) )
Could help to figure the needed cropping values more easy.

Thanks!, that's quite a reasonable solution.
