Issue with video panning in MPC-BE 1.7x and above

[Mauro-Cioccarelli]

I've been using MPC-BE for a while and I've noticed a significant change in video panning behavior starting from version 1.7x.

In previous versions (1.6x and below), I was able to pan the video all the way to the top and bottom of the screen. This allowed me to zoom in on any part of the video, even in the extreme corners.

Mpc-be is the only one video player with this function and i use it a lot for my videoclips

However, in version 1.7x and above, the panning is limited to approximately 50% of the screen. Even when zooming in, I cannot pan the video further up or down. This makes it impossible to zoom in on the extreme top or bottom parts of the video.

I've already tried:

Checking the zoom settings Disabling other software that might interfere Reinstalling the latest graphics drivers Resetting MPC-BE to default settings I've also tried installing version 1.6x and the panning works as expected.

I believe this is a bug that has been introduced in version 1.7x.

To reproduce the issue:

Open a video in MPC-BE 1.7.3 Try to pan the video all the way to the top or bottom. Notice that the panning is limited. Zoom in on the video and try to pan again. Expected behavior: The video should be able to pan all the way to the top and bottom of the screen, regardless of the zoom level.

System information:

Operating system: Windows 10 MPC-BE version: 1.7.3 (now downgraded to 1.6.8) Graphics card: nvidia gtx 3080 I hope this information is helpful in identifying and resolving this issue. Thank you for your time.

Yes. It is possible that zooming no longer works as it used to. I would ask you to take a screenshot of the original frame and the zoom result that you could get in the old version. Also, tell me what keys you used.

Thank you for your prompt response.

I've attached screenshots of the original frame and the zoomed-in result that I was able to achieve in version 1.6.8. and in version 1.7.3

Take a look on the yellow object at top left of the frame:

Original frame:

Max zoom in version 1.7.3:

I can zoom more but the top left corner will go outside of the view area.

Max zoom in version 1.6.8

I used the following keys:

Keypad 9 to zoom in Keypad 1 to zoom out Ctrl+Keypad numbers to move frame Ctrl+Keypad 5 to reset zoom and pan

With old version i 1.6.8 I was able to pan the zoomed-in image to any part of the video, including the extreme top and bottom.

I hope this information is helpful in identifying the issue. Please let me know if you need any further details.
