SharpCap Forums

This is a minor problem overall, but seems worth fixing as it sometimes causes some confusion.

When a camera is initially connected, the default zoom seems to be picked from the previous session. However, zoom 150% starts up at 100% image-zoom, while the combo shows 150%. Selecting a different value from the combo works as it should.
Also, zoom ratios < 100% seems to startup at even lower image-zoom than the combo, a 16% image zoom + close camera + open camera = ~5% image zoom.
To sum up, apply the actually selected (proper) zoom-ratio once the camera starts up.

I have seen this on my other cameras, but did this testing on a Microsoft Lifecam Studio.

Hi,

in my testing the default zoom in the settings seems to be ignored, but the zoom is saved between closing the camera (or closing SharpCap) and re-starting. I can't see an issues with a different zoom when restarting so far (testing with 3.1.5108).

I will take the 'default zoom' out of the settings as that is now obsolete - please let me know some more details of how to get this problem to happen so I can investigate further.

cheers,

It seems there are more variables involved here than I initially suspected.

It seems to work correctly on a HD-screen (1920x1080), but behaves oddly on 4k-screens. And ofc I earlier only tested on my normal computers (imaging laptop and processing desktop), which both have 4K-screens.

Attached are two images, I choose to display the behaviour at small images as the large images would take up a lot of space. The behaviour is similar at large scales.
1. Image when 16% is manually selected, as displayed in the zoom-combo. This looks perfectly normal. 2. Image at 16% when camera is opened, actual size is around 5% perhaps, and there is a black bottom indicating that the actual image is resized to fit in an incorrectly dimensioned frame.

Choosing Zoom 'Auto' seems to work correctly for .2, choosing specific zoom-ratio seems to cause the problem.

I see nothing wrong once a Zoom is manually selected, only when the camera is first initialised. Seems to affect my other cameras as well. The windows settings of the screens are 100% scale, and changing screen-resolutions have no effect on the above behaviour (probably since the monitors are 4k and other resolutions are simply interpolated).

Ah!

I will add this to the list of things to sort out related to 4k screens when I get around to getting one. In general I've set the program up to scale the UI and that works for most things, but not quite everything.
