VerticalVideoSyndrome is a tweak released during this evening in Cydia, and through it we can make sure that we will not record video clips in any orientation other than landscape, which allows them to be viewed correctly on widescreen screens. You can see in the image above what kind of error will be displayed on the screens of the iDevices when you do not orient the terminals in a horizontal position for recording video clips, and in this way you will ensure that you always record multimedia content correctly.
This tweak displays a warning image when a user's device is in recording mode and their phone's device is vertically oriented. The user can still record if they choose to but they will at least be aware of what they are doing. The goal is to help stop people from filming vertical videos. To change the warning image, goto "Library/MobileSubstrate/DynamicLibraries/VVS.bundle" and change the image with your own. Make sure the name is "Warning.png".
VerticalVideoSyndrome it is available for free in the repo BigBoss al Cydia.
