Ok. As long as your are away of it.

I agree, yeah this difference is a long standing issue, but not easy to fix. Attempted the refactoring a few times.

The other aspect where this is limiting is that you can't have drawings go outside the video rectangle in the player, whereas in the capture screen you can, for example a corner of a perspective grid may be out of view.

When reviewing a video in playback mode, the file is opened to show the complete width and height of the video in the playback panel. I use two cameras and therefore review two videos at a time. So each video is opened such that the width fills the playback panel. This leaves a lot of unused vertical space. A subsequent zoom just zooms the video contents (image) but does not expand the video height into the available vertical space. This unnecessarily leaves a lot of the image cropped.

In contrast, when viewing a live camera, a zoom first expands the video height (or width) to fill the camera panel and then continues to zoom the contents (image) using the whole camera panel.

Is it possible to have the playback zoom behave like the camera zoom and first expand the video display to fill the playback panel?
