How to make a horizontal video?

The methods of making horizontal video are: video shooting, video editing software, adjusting the direction of the picture, exporting and saving.

1. Video shooting: use corresponding shooting equipment (such as mobile phone and camera) to shoot horizontally. Make sure the device is set to landscape mode, and select the appropriate shooting angle, light and background.

2. Video editing software: import the shot video into video editing software, such as Adobe Premiere, Final Cut Pro, iMovie or other similar software. These softwares can provide rich editing tools and effects, so that you can edit and process videos.

3. Adjust the picture direction: In the video editing software, you can adjust the rotation angle of the video to rotate the vertically shot video to the horizontal direction. This can usually be achieved by selecting the rotate or flip option in the video editing software. Make sure that the video is rotated 90 degrees so that it is in the correct landscape orientation.

4. Export and save: After editing, export the video to the final version in landscape format. Select appropriate output settings, such as resolution, frame rate and video encoding, and save the video in the required file format, such as MP4 and MOV.

Video size requirements

The aspect ratio of the screen picture and the screen width-height ratio can be expressed by the ratio of two integers or a decimal, such as 4 to 3 or 1.33. The aspect ratio of common computer monitors and data signals to common TV signals is 4 to 3 or 1.33, and the aspect ratio of movies and DVDs to HDTV is 16 to 9 or 1.78.

When the aspect ratio of the input source image is different from the aspect ratio supported by the display device, picture distortion and loss will occur. /kloc-the image of 0/6 to 9 is 4 to 3. There are three ways to display on the screen: the first way is an anemometer, which stretches vertically until the screen is full, so that the image looks thinner than before.

The second way is the mailbox-one way. The image of 16-9 keeps its ink deformation, but leaves a black bar at the top and bottom of the screen. The third mode is letter box -b mode, which is a compromise between the first two modes, and both sides in the horizontal direction exceed a part of the screen.
