OpenShot Video Editor is a free, open-source video editor for Linux licensed under the GPL version 3.0.  OpenShot can take your videos, photos, and music files and help you create the film you have always dreamed of. Easily add sub-titles, transitions, and effects, and then export your film to DVD, YouTube, Vimeo, Xbox 360, and many other common formats.

Blender Features.

---

• Support for a variety of geometric primitives, including polygon meshes, fast subdivision surface modeling, Bezier curves, NURBS surfaces, metaballs, digital sculpting, outline font, and a new n-gon modeling system called B-mesh.
• Internal render engine with scanline ray tracing, indirect lighting, and ambient occlusion that can export in a wide variety of formats.
• Experimental new Cycles pathtracer render engine.
• Integration with a number of external render engines through plugins.
• Keyframed animation tools including inverse kinematics, armature (skeletal), hook, curve and lattice-based deformations, shape keys (morphing), non-linear animation, constraints, and vertex weighting.
• Simulation tools for Soft body dynamics including mesh collision detection, LBM fluid dynamics, smoke simulation, and Bullet rigid body dynamics.
• A particle system which includes support for particle-based hair.
• Modifiers to apply non-destructive effects.
• Python scripting for tool creation and prototyping, game logic, importing and/or exporting from other formats, task automation and custom tools.
• Basic non-linear video/audio editing.
• Game Blender, a sub-project, offers interactivity features such as collision detection, dynamics engine, and programmable logic. It also allows the creation of stand-alone, real-time applications ranging from architectural visualization to video game construction.
• A fully integrated node-based compositor within the rendering pipeline.
• Procedural and node-based textures, as well as texture painting, projective painting, vertex painting, and weight painting.
• Realtime control during physics simulation and rendering.
• Camera and object tracking.

Object creation

• Drawing: pencil tool (freehand drawing with simple paths), pen tool (creating Bezier curves and straight lines), calligraphy tool (freehand drawing using filled paths representing calligraphic strokes) Shape tools: rectangles (may have rounded corners), ellipses (includes circles, arcs, segments), stars/polygons (can be rounded and/or randomized), spirals Text tool (multiline text, full on-canvas editing) Embedded bitmaps (with a command to create and embed bitmaps of selected objects) Clones (“live” linked copies of objects), including a tool to create patterns and arrangements of clones

Object manipulation

• Affine transformations (moving, scaling, rotating, skewing), both interactively and by specifying exact numeric values Z-order operations Grouping objects, with a way to “select in group” without ungrouping, or “enter the group” making it a temporary layer Layers, with a way to lock and/or hide individual layers, rearrange them, etc; layers can form a hierarchical tree Copying and pasting objects Alignment and distribution commands

Fill and stroke

Multi-line text Uses any installed outline fonts, including right-to-left scripts Kerning, letterspacing, linespacing adjustments Text on path (both text and path remain editable) Text in shape (fill shape following stroke)

Rendering

• Fully anti-aliased display Alpha transparency support for display and PNG export Complete “as you drag” rendering of objects during interactive transformations
• Misc Live watching and editing the document tree in the XML editor PNG and PostScript export Command line options for export and conversions Perfectly compliant SVG format file generation and editing

, with many predefined dash patterns Path markers (e.g. arrowheads)
Operations on paths

• Node editing: moving nodes and Bezier handles, node alignment and distribution, etc. Converting to path (for text objects or shapes), including converting stroke to path Boolean operations Path simplification, with variable threshold Path insetting and outsetting, including dynamic and linked offset objects Bitmap tracing (both color and b/w)

Text support

• Multi-line text Uses any installed outline fonts, including right-to-left scripts Kerning, letterspacing, linespacing adjustments Text on path (both text and path remain editable) Text in shape (fill shape following stroke)
