To permanently change the aspect ratio of a video, you will need a video converter or editor. In this case, I recommend using the Wondershare Filmora video editor, specifically the latest version 9, which is supported by Windows 10. With this editor, you can easily create videos with dimensions of 4:3, 16:9, 9:16, and 1:1.
Reducing File Size
Modifying Document Resolution
To reduce the size of a file, you can try modifying the resolution of the document using your scanner’s control software. Keep in mind that reducing the parameter dpi (dots per inch) to a minimum will result in a small loss of quality.
Compressing Videos on Mobile Devices
If you want to compress a video in MP4 format on your smartphone or tablet running Android, I recommend using the Video Compress application. This app allows you to adjust the final quality by reducing the video size.
Compressing Videos in a Compressed Folder
To compress multiple videos into a compressed folder, follow these steps:
- Select all the videos you want to compress in a folder.

Using WinZip to Compress Videos
To compress videos using WinZip, follow these steps:
- Open WinZip.
- Select the videos you want to compress in the WinZip file pane.
- Click on "Add to Zip".
- Save the compressed video in a specific location.

Video Formats Supported by Televisions
Most televisions support MP4 files, and many models also support AVI, 3GP, and MKV videos, as well as various video codecs.
Free Video Compression Options
One excellent free and open-source application for compressing and converting videos into optimized file formats for computers, iPads, iPhones, and iPods is HandBrake. It is extremely user-friendly. Simply select the format and the original video before starting the conversion.
Improving Video Quality
If you are using a Windows PC, the most effective method for modifying video resolutions is to use VirtualDub, an excellent free program for video editing. Among its features, it allows for significant reduction in the size of AVI and MPEG videos.
