The VLC Media Player is not just as simple as it looks. In addition to basic video/audio decoding, it also has many hidden features that people have overlooked, such as interactive zoom. This feature comes in handy when you want to zoom in specific areas of a video. Today, I will introduce how to enable VLC interactive zoom and a simple solution for VLC zoom video not working issue.

Why Sometimes VLC Interactive Zoom Doesn't Work?

Q: I would like to ask why interactive zoom functionality works properly on horizontally filmed videos, but it doesn't work at all on any vertically filmed video. The rectangle for zooming position isn't movable in the preview window on any vertical video. Is it some kind of Interactive Zoom functionality imperfection, which could be fixed in the future or if it's some global limitation? - From The VideoLAN Forums


A: Well, it's a common issue on VLC official forum. The same problem is also put forward in these two threads

And you can find more results if you dig deep into the forum. That is to say, the issue has not been solved so far.

The Video Recorded with 90-degree RotationThe Video Recorded with 90-degree Rotation

Actually, the root cause of the problem is derived from specific videos themselves. Some videos inherently come with a 90° rotation parameter, especially for those videos recorded by smartphone or other portable devices. You can analyze and find this information using MediaInfo. If you play this video in Windows Media Player, you'll find it plays upside down. VLC can read the rotation parameter and rotate the video automatically, but the interactive zoom won't move because of it. So the solution is that, VLC Media Player zoom feature will work as soon as the parameter is removed.
