Video Cutter for Windows User Guide - How to Losslessly Cut, Merge and Edit Video/Audio

After launching TunesKit Video Cutter, you should click the "Open" button or drag the media file to add the video/audio into the cutter. It only supports adding one video or audio file each time.

Once imported, the video/audio file would begin to play automatically in the pre-view window. Then you got two options to set the duration of the segment that you want to split from the source media. The easier one is to select the segment by controlling the slider bar. The other yet more precise one is to set the start time and end time manually which is accurate to millisecond.

Thanks to the built-in video editor of TunesKit Video Cutter for Windows, you can customize the video or audio clips with multiple effects before starting to cut the media. To edit the videos, simply click the "edit" icon displays in each segment. There you can personalize your video by trimming, changing aspect ratio, adjusting brightness, adding watermarks, subtitles and other effects according to your own needs.

It also provides the option for you to cut multiple segments from the same source file. Simply click "+" button and it will create a new footage for you. If you want to merge those different media segments being cut from the same source file into one, you can simply check the option of "Merge Segments".

Clicking "Format" button, you'll be directed to the window where you can select the output format and device. Currently TunesKit Video Cutter offers hundreds of output formats and mobile devices for you. You can also customize the media parameter like codec, size, bit rate, etc. if you like.

Note: To keep the lossless quality of the original video while cutting, you are suggested to select the High-Speed Mode.
