"Does anyone know how to resize a video? I want to upload a video but the size is too big. Which software should I use? Any help would be very much appreciated. Thanks a lot in advance!"

There are conditions in daily life we have the demand to resize video: original video is too large so you have to resize video for YouTube and other website uploading, or current video resolution is too large for small screen device playing, or source is not suitable for wide screen player playback, etc. Maybe you have used the cropping/panning method to resize a video, however, you lost your video because it actually cropped instead of resized, so you must wonder if there’s a way to resize video files without content loss.

Actually, two ways are provided for you to resize video files:

Choose to convert a video format to another one with smaller size. For instance, if you want to resize video for uploading to YouTube, but the AVI video available is too large, you can convert AVI to FLV format with smaller size. Generally speaking, video formats like FLV, RMVB, MP4, 3GP are with smaller size.
Remain original video format but reset video parameters including Video Size (Resolution), Frame Rate and Aspect Ratio to shrink video size. To change video resolution, it is suggested not to exceed the source video resolution so as to guarantee image quality.

Many video converters support video conversions among almost all video format, but fewer of them are able to resize a video. Here Leawo Video Converter is highly recommended for you to resize video files via the above two methods on Windows. And to resize a video on Mac, Leawo null is also accessible.
