How To Install OpenShot Video Editor 2.4.1 released On Ubuntu 17.10

   OpenShot Video Editor is a free, open-source video editor for Linux. 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.


OpenShot 2.4.1 release highlights:

  • Improved Image Quality : improved the image processing pipeline in OpenShot to create sharper images, by switching our image scaling algorithm, and most importantly, only scaling a frame once, as opposed to multiple times (which used to happen in certain scenarios). This results in a noticeably sharper image, and slightly better performance.
  • Improved Playback Smoothness : The video preview capabilities in OpenShot have been improved to better handle higher framerate videos (50 fps, 60 fps, 120 fps). This results in a smoother playback experience, and less jittering and freezing with certain preview profiles.
  • Improved Stability (especially for Windows) : This fixes many, many Windows issues, including audio files stopping early, sync/desync issues, videos stopping at 30 minutes (or at an earlier time), opening project files with non-English characters, and more. If you have had any issues on Windows, please give this new version a try.

OpenShot 2.4.1 release Changelog:

Libopenshot (full list of changes)
  • More critical sections trying to prevent race conditions on high CPU core systems
  • Additional critical sections around adding frame images
  • Codec lookup by name in FFmpegWriter, which should solve a few issues (such as xvid support). Thanks Peter!
  • Fixing regression with rotation origin. Things should always rotate around the center of an object (until I add in keyframable anchor points)
  • Setting timebase on video stream in FFmpegWriter... a bit experimental
  • Improving playback smoothness on high framerate videos, especially when the video frames need to jump forward to keep up with the audio.
  • Removing throw statements from header files
  • Reducing # of scale operations to 1 per layer on the timeline
  • Fixing 16 thread limit on FFmpegReader
  • Fixing a cast from long to int64_t
  • Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. This is a big one!
  • Removing variable bitrate support (for now), since it causes more problems than it solves.
Openshot-qt (full list of changes)
  • Fixing small regression with translation website URLs when using default/en_US
  • Fixing small bug in Export dialog where profile and quality get blown away when changing format
  • Ignoring history update messages, since libopenshot doesn't care about them
  • Simplifying export progress, reducing # of signals being emitted
  • Integrating current language into website URLs and simplifying a few translations (removing HTML tags)
  • Removing unneeded UTF8 encode method, which caused certain project paths to fail when loading (solves crash on Windows trying to open non-English project file paths)
  • Fixing a big race condition on initial launch of OpenShot, which causes certain JavaScript calls to fail (so default profiles, snapping mode, and few other things set on launch would fail sometimes)
  • Adding keyboard shortcuts for toggling 'Transform' and 'Insert Keyframe'. This improves the animation work-flow, and no longer requires a bunch of mouse clicks / context  menus for animations.
  • Preventing overwriting an input file with the export dialog, and updating export progress on export window title
  • Updating translations and contributor credits
