Set Video/Audio Parameters to Resize Video

Step 1. Import Target Video File
Launch this WinX video resizer and tap +Video button on navigation bar to import the video file you want to resize.

Step 2. Select Output Format
In fact, video format/codec plays an important role in video size. Some video formats/codecs like H.265 which supports 8K resolution contributes large size for a file. Therefore, if you want to resize a HD video, it's better to compress the video to a format with compact file size but good quality, like MP4, AVI. If you want to get a smaller video size with plain quality, FLV and 3GP are good choices.

Step 3. Personalize Video/Audio Parameters
After choosing a suitable format, tap the setting button to access to video/audio options. Higher resolution, bit rate and frame rate leads to bigger video size. Adjust those parameters to lower value for video resizing.In addition, if you lower the resolution from 1280x720 for widescreen to 640x480, please change aspect ratio from 16:9 to 4:3 fitting with the resolution. You can also alter audio options to reduce more video file size.
