Luckily, here comes the best free video rotate software - Free HD Video Converter Factory, which can help you remove the hidden parameter so as to fix the horizontal issue for vertical videos. However, quite a number of software on the market fails to recognize the hidden rotation parameter, which leads to an unacceptable tensile deformation while editing, converting or uploading. That's the reason you cannot view it properly on desktops, laptops, TVs or 16:9 large screens. When you stream the recorded video or transfer it to PC for playback, the parameter is still there. And the device itself has a rotation mechanism, for instance, coming with an orientation parameter " rotate 90 degrees", which will convert vertical videos to horizontal automatically. For convenient operation, many people prefer to shoot videos vertically with one hand, rather than record it in landscape orientation with two hands.

A: Have you ever captured a video in portrait orientation with your smartphone, compact camera or other handheld devices but find it reoriented on your TV or PC player? If you get into this problem, you're not alone.
