Kdenlive (KDE Non-Linear Video Editor) is an open source video editing software package based on the MLT Framework, which focuses on flexibility and ease of use. The development of Kdenlive has moved on from the K Desktop Environment 3 version (which wasn’t originally made for MLT) to KDE Platform 4, with an almost complete rewrite.
Kdenlive packages are freely available for GNU/Linux, FreeBSD and Mac OS X under the terms of GNU General Public License version 2 or any later version.

Kdenlive supports all of the formats supported by FFmpeg (such as QuickTime, AVI, WMV, MPEG, and Flash Video), and also supports 4:3 and 16:9 aspect ratios for both PAL, NTSC and various HD standards, including HDV and AVCHD. Video can also be exported to DV devices, or written to a DVD with chapters and a simple menu.




DraftSight is a free 2D CAD (computer-aided design or computer-aided drafting) product for engineers, architects, designers, draftspeople, students and educators. The product was developed by Dassault Systèmes and lets users create, edit and view DWG and DXF files.
DWG files contain the binary data for CAD design and it is the drawing format for many CAD programs. DWG is a long-time abbreviation for “Drawing.” A DXF, or Drawing Exchange File, is used to convert CAD files into a generic format that can be read by another CAD software product.
DraftSight competes against more than three dozen 2D or 2D/3D hybrid products on the market. General availability of DraftSight for Windows was released in February 2011 and was downloaded more than 1,000,000 times.
