With the popularity of HD cameras and the preference for 4K UHD/1080P high definition, a very short video can easily run several gigabytes in size. This enforces users to reduce and compress video size to make the video smaller for different reasons. For example, to allow the videos to be uploaded to web like YouTube or sent via email to family or friends, you have to make video size smaller than 2GB for YouTube and 25MB for most email system. Another simple example, you will need to pay extra $100 to get an iPhone 6S with larger storage. So, in the final analysis, is there any video size compressor or way to compress and reduce video file size from HD/UHD MP4, MKV, AVI, MOV etc?

Windows Movie Maker is a professional compressor claiming that they can reduce video file size. However, with the release of Windows 10, Windows Movie Maker is no longer available. Here is an alternative that works equally well to make large files smaller, Pavtube Video Converter Ultimate. This file compressor can significantly shrink the file size without losing any quality by converting the video to smaller formats like FLV, WMV, AVI, RMVB etc, adjusting various video audio settings, cutting unwanted parts etc. I have used it to compress a MP4 video which is 108MB. After compression the size is 30.1MB only while I can’t identify any quality loss. It can reduce up to 70% of the file size from 4K UHD/HD 1080P.
