After a year and a half of development, the release of the free non-linear video editing system OpenShot 2.6.0 has been published. The project code is licensed under GPLv3: the interface is written in Python and PyQt5, the video processing core (libopenshot) is written in C++ and uses the capabilities of the FFmpeg package, the interactive timeline is written using HTML5, JavaScript and AngularJS. For Ubuntu users, packages with the latest release of OpenShot are available through a specially prepared PPA repository, for other distributions, a self-contained build in AppImage format has been generated. There are builds for Windows and macOS.
The editor features a user-friendly and intuitive user interface that allows even novice users to edit videos. The program supports several dozens of visual effects, allows you to work with multi-track timelines with the ability to move elements between them with the mouse, allows you to scale, crop, merge video blocks, ensure smooth flow from one video to another, overlay translucent areas, etc. It is possible to transcode video with a preview of the changes on the fly. Using the libraries of the FFmpeg project, OpenShot supports a huge number of video, sound and image formats (including full support for SVG).
Major changes:
- The composition includes new effects based on the use of computer vision and machine learning technologies:
- The stabilization effect helps to eliminate distortion caused by camera shake and movement.
- The tracking effect allows you to mark an element on the video and track its coordinates and further movement in frames, which can be used to animate or attach another clip to the coordinates of the object.
- An object detection effect that allows you to classify all objects in the scene and highlight certain types of objects, for example, mark all cars in the frame. The resulting data can be used when organizing animations and attaching clips.
- Added 9 new sound effects:
- Compressor - increases the volume of quiet sounds and reduces loud ones.
- Expander - Makes loud sounds even louder and quiet sounds quieter.
- Distortion - changes the sound through signal truncation.
- Delay - Adds delays to synchronize audio and video.
- Echo - sound reflection effect with a delay.
- Noise - adds random noise at different frequencies.
- Parametric EQ - allows you to change the volume with reference to frequencies.
- Robotization - Distorts the voice, making it sound like a robotic voice.
- Whisperization - Converts the voice to a whisper.
- A new Zoom Slider widget has been added to simplify timeline navigation by dynamically previewing all content and displaying a reduced representation of each clip, transform, and track. The widget also allows you to select the part of the timeline of interest for a more detailed view by defining the visibility area using blue circles and moving the generated window along the timeline.
- Work has been done to increase productivity. Some operations have been switched to a single-threaded execution scheme, which allowed us to achieve higher performance and bring the speed of operations closer to calling FFmpeg without interlayers. The transition to the use of the RGBA8888_Premultiplied color format in internal calculations has been made, in which the transparency parameters are pre-calculated, which made it possible to reduce the load on the CPU and increase the rendering speed.
- A completely redesigned transformation tool (Transform) is proposed, allowing you to perform operations such as resizing, rotating, cropping, moving and scaling. The tool is automatically activated when any clip is selected, is fully compatible with the keyframe animation system and can be used to quickly create animation. To simplify tracking the position of the region during rotation, support for the reference point (a cross in the middle) is implemented. When zooming with the mouse wheel during the preview, the ability to view objects outside the visible area has been added.
- Snapping operations have been improved, including support for snapping during clip trimming to make it easier to align clipping that spans multiple tracks. Added support for snapping to the current playback position (playhead).
- A new Caption effect has been added to draw text with subtitles on top of the video. You can customize the font, color, borders, background, position, size, and padding, as well as apply simple animations to fade text in and out.
- Provided the ability to define parent keyframes to make it easier to manage complex animations and navigate the large timeline. For example, you can link a set of clips to the same parent and then manage them in one place.
- Added new icons for effects.
- The composition includes collections of about a thousand emoji from the OpenMoji project.
- Added support for FFmpeg 4 and WebEngine + WebKit. Updated Blender support.
- The ability to import projects and clips in the ".osp" format is provided.
- When rotating an image, EXIF ββmetadata is taken into account.
- Added support for Chrome OS platform.
