Video editing always needs a good tool like Torrent Video Cutter, which lets you cut any video into various smaller fragments. You can cut the following formats: AVI, MPEG, VOB, WMV, ASF, RM, RMVB, 3GP and MP4.
Of course, after cutting, the resulting fragments keep the same quality as the original, in both audio and video. The Torrent Video Cutter user just needs to indicate the start and end points for the cut.
For Torrent Video Cutter to work correctly you need to previously install DirectX 8.1 or later.
