OpenShot Video Editor is an open source non-linear video editor software, built with Python, GTK, and the MLT Framework.

OpenShot aims to create an simple, yet powerful video editor, with a focus on "User Interface", "Work flow", and "Stability".

System requirements

  • Python
  • GStreamer
  • gtk+
  • MLT Framework

What is new in this release:

  • Improved Image Quality:
  • We have 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):
  • Right after our previous release (in September 2017) we made some very large changes to libopenshot to better support Windows (with respect to certain data types in C++). 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.
  • But is it really more stable?:
  • Yes. Each release we fix actual stability issues, and continue to find race conditions, and add more protection around high risk code (such as image data). On certain systems, and with different combinations of video cards, CPUs, and OSes, some crashes happen often (which is less than ideal), and on other systems, it doesn't crash at all. Each time we can reproduce a crash, we fix it, and the net result is statistically less crashes with each new version of OpenShot. We have reduced the # of crashes by a factor of 10 in the past 12 months, and will continue to work hard in this area.
  • New Video Tutorials:
  • I am proud to announce a new series of video tutorials is in the works, and the first few are now available. I will be adding more videos very soon, and look forward to building a comprehensive collection of short (5 to 10 minutes) tutorials, covering all the features, secrets, and workflows built into OpenShot.

What is new in version 2.4.0:

  • openshot-qt (Video Editor)
  • Improving undo/redo support. Now the last X number of undo/redo actions are stored in the project file. The number can be adjusted in the prefences, under the auto-save tab. This also vastly improves the usefulness of the auto-save system, since it saves your undo/redo history as well.
  • Fixed Image Sequence exporting. Supports PNG, JPG, PPM, BMP and a few others. Also added 'Audio Only' and 'Video Only' export options.
  • Adding new Freeze and Freeze & Zoom presets, to quickly insert freezes into clips.
  • Removing 'show waveform' from separate audio menu, to increase speed of separating audio.
  • Protect file menu from invalid file_id.
  • Protect timeline dropEvent from empty item_id.
  • Cloaking timeline body until Angular loads fully (so we don't see the occasional pop-in debug layout).
  • Updating translations and supporters.
  • Bumping version to 2.4.0 (minimum libopenshot version 0.1.8).
  • libopenshot (Video Library)
  • Prevent crashes related to too many threads (on 24+ thread systems).
  • Migrating tr1 to std, adding C++11 support to build scripts, fixing crash in FFmpegReader (caused by shared_ptr, buffer, and last_video_frame corruption). Much improved stability with this change. Thanks to Craig and Peter for the help!
  • Fixing crash on Ubuntu build server.
  • Fixed a strange bug related to exporting image sequences. The filename property was not being set on the AVFormatContext. Also fixed a bug when exporting to JPEG image sequences related to max_b_frames and certain codecs.
  • Fixing issue with incorrect image size caches, which results in blurry/smudgy scaling on certain things.
  • Fix issue with loading time curves that are never processed (i.e. have no values)
  • Adding additional locks when adding/changing audio data. Reducing FrameMapper to a single frame at a time.
  • Fixing crash on Time keyframes where it would sometimes calculate an invalid frame number.
  • Fixing audio pops when stacking multiple clips with different offsets (pretty big issue for some people, just depending on your source framerates and position/start of clips).
  • Removing nested OMP processing from FrameMapper. Adding lock inside time mapping (to prevent crashes when speeding up/slowing down clips). Adding omp critial lock to Frame GetAudioChannelsCount() and GetAudioSamplesCount() methods.
  • Bumping version to 0.1.8 (SO version 13).

What is new in version 2.3.3:

  • New release of openshot-qt! Bumping version to 2.3.3, and libopenshot depenency to 0.1.6
  • Adding CFBundlePackageType key to Info.plist, and symlinking a few files which I don't think are considered executables in the app bundle. A bit experimental, but trying to overcome an issue with Gatekeeper on OS X Sierra.
  • Fixed SpaceMovie 3D animated title alpha key frames, and adjusted the position of the main title to be better centered when it appears.
  • Fixing bug when selecting effect on a clip (where selection dropdown would not populate)
  • Fixed bug on certain systems when loading list of all supported languages.
  • Fixed backup recovery issue which would not refresh the timeline on load.
  • Fixed bug destroying the lock file (if another process already deleted the lock file).
  • Added C++ exception parsing from archived exception data.
  • Adding a script to parse and aggregate Python error logs for OpenShot
  • Another attempt to fix the race condition causing the "zipimport.ZipImportError: can't decompress data; zlib not available" when launching a frozen version of OpenShot.
  • Fixed a common error on the title editor (caused by a missing font-style).
  • Protecting query classes more, to prevent invalid clip/tran/effect ids from crashing
  • Removing NVidia driver from AppImage (build server)
  • Updated supporters and donors file
  • Updated translations and improved translation test script (which validates all string replacements are found in translations)
  • New release of libopenshot (0.1.6):
  • Fixing Timeline::SetJSON to use a lock, and reopen the reader if already open. This fixes an issue when trying to open another project while the current project is being accessed (i.e. during playback).
  • Adding additional lock on ClearAllCache method, to prevent crash
  • Fixing a data type issues with max()
  • Big improvement with handling invalid video and audio timestamps, defaulting to more sane values (when huge crazy timestamps are detected).
  • Fixing a bug when disabling video/audio tracks on FrameMappers.
  • Adding additional bail-out code when stuck searching for a video/audio packet that probably doesn't exist.
  • Added improved "checked frame" handling, and once 1 frame is detected as invalid, clean out any other invalid ones as well.

What is new in version 2.3.1:

  • Transform Tool:
  • We have added a new transform tool, which allows real-time transformations in the video preview window. Right click on any clip, and choose "Transform" to enable the tool. Using your mouse, move and scale the clip as needed, all while enjoying a real-time preview. Animating the location and scale of clips has never been easier!
  • Zooming Improvements:
  • Zooming in and out of the timeline, in order to increase precision of your edits, has been greatly improved. When zooming the timeline, it now centers on your mouse position, similar to image editing applications. The zoom scale is also now saved in each project file, which saves some time when jumping back into a project. When your mouse is over the timeline, hold CTRL+mouse scroll wheel to zoom in and out.
  • Razor Tool:
  • Back by popular demand, the razor tool from OpenShot 1.4.3 has returned from the dead. Click on the Razor toolbar button to switch to razor mode. Now click on any clip or transition to quickly cut them (holding CTRL and SHIFT modify the razor to only keep the left or right side). Alternatively, you can cut a clip at the Playhead position by right clicking and choosing "Slice", by using CTRL+K, or by grabbing the edge of the clip and dragging.
  • Improved Title Editors:
  • Many improvements have been made to the Title Editor and Animated Title Editor. Both editors now display a grid of thumbnails, to make finding the right title easier. Save dialogs are no longer used, and instead title files are saved directly into your project folder. New "Edit Title" and "Duplicate Title" menus have been added, to assist in quickly making changes to titles.
  • New Preview Window:
  • Previewing files now has its own dedicated video player, which allows for multiple video preview windows at the same time. Also, audio files render a waveform by default. The speed of previewing files is also improved, using the improvements mentioned below.
  • Huge Performance Improvements for Real-time Previews:
  • Performance improvements are always a high priority, and we've made some really great improvements to the speed of real-time previews. We've also fixed some bugs related to freezes and hangs, caching improvements, frame detection, and better logic to determine the max size of our preview window, so we can optimize by not rendering images and frames larger than the preview window. The end result is the best real-time preview performance yet for OpenShot.
  • New Documentation:
  • I have finally gotten around to publishing a User Guide for OpenShot 2.x. I am using the Sphinx documentation system (which is really great), and I think this will be very useful for new users, and any user who wants to get the most out of OpenShot. It is currently only available in English, but I will soon start the translation process for it.
  • Audio Improvements:
  • Fixes for audio sample distribution, caching, off by 1 errors, and various frame boundary improvements (Thank you Nelson H). Also, improvements to audio device management, which is how OpenShot communicates with the audio system on each OS.
  • Improved Export Dialog:
  • Export dialog has been improved to re-load the project, clear cache, and export without requiring any ties to the real-time preview system. This fixes many freezes and hangs when attempting to export, and is a much more stable approach. Also, on Linux, export progress is now displayed on the launcher icon (in Unity and other launchers).
  • New Windows Build Server:
  • As you might have heard, my Windows development system (and build server) died (again)... stopping all Windows builds for a few weeks. Hard-drive and motherboard issues (and possibly other problems too). A HUGE thanks to John Fields and his band of merry Open Source Saturday folks. They donated a wonderfully nice computer (i7, 16GB RAM), and their only request was that it be called StarLord! Done! StarLord is up and running, and is working beautifully!
  • GitHub Bug Management:
  • With the help of a few volunteers (Ankit, Justin, Jt, and others), we've been able to reduce our GitHub bug count from over 380+ bugs to less than 200. Many of those 200 should be resolved with version 2.3, so I still have some work to do in this area, but making great progress! I've also added some GitHub templates when filing new bugs, to help increase the quality of new bug reports, and guide users on generating and attaching log files.
  • Translations:
  • OpenShot 2.3 is fully translated in 11 languages, and partially translated in more than 60 others. If you notice untranslated text in your native language, please feel free to submit your own translations on LaunchPad.
  • 100% translated in the following languages:
  • Spanish
  • French
  • Italian
  • Portuguese
  • Brazilian Portuguese
  • Greek
  • Ukrainian
  • Catalan
  • Malay
  • Icelandic
  • English (United Kingdom)
  • Additional Features:
  • Added new welcome tutorial message, which contains a checkbox for disabling anonymous error and metrics reporting. That can also be adjusted in the Preferences, but it has been often requested to allow new users to opt-out.
  • All child windows now center on parent window
  • Ability to easily display frame numbers on frames
  • Improved accuracy when calculating frame numbers
  • Improvements to frame accuracy, especially when zoomed in at max zoom
  • Dramatically increased speed of selecting and unselecting large numbers of clips/transitions.
  • Refactor loading properties for selected items, to improve speed.
  • Refactoring and improving preview playback of files, and preview playback during resize/trim (which now maintains aspect ratio correctly).
  • Improving long filename support in file tree/list views, and improving thumbnail/grid view on all listviews (effects, transitions, titles, animated titles, etc...)
  • Updating translation files (with a few minor corrections to string formatting arguments).
  • Improving test_translations.py script, which helps me detect problems with missing formatting args.
  • Fixed an issue preventing the track names from being translated on launch.
  • Adding "width x height" to list of profiles on Export and Profiles screens, to make the output resolution more clear
  • Improved logic for "Next Marker" and "Previous Marker" buttons to include the selected items (start and end positions), to allow quickly jumping to the beginning or end of a selected clip.
  • Prompting user to find missing files when opening a project, and updating translation template.
  • Prompt user to save before creating or opening new project file (if needed)
  • Make effects container on a clip visible on hover (regardless of how small the clip is).
  • Tweak tooltips of clip title so they don't cover up the menu button and effects.
  • Making settings save to disk as they are changed in preferences.
  • Setting focus to Project Files on launch, so the properties filter doesn't auto get tab focus (preventing certain keyboard shortcuts).
  • Switching snapping logic to compare pixels (not time), so it's still useful at close and far zoom levels. Reducing snapping to 10 pixels. Fixing bug when updating new properties for a clip.
  • Bug Fixes:
  • Fixed regression with selection dropdown
  • Fixed crash when pasting keyframes onto a clip/transition
  • Fixing incorrect placement of a selection handle
  • Fixed a bug when caching a mask size (a regression from some of our speed improvements)
  • Fixed small bug with Next Marker and Previous Marker buttons (not handling position 0 correctly).
  • Fixed bug in transform callback, where transformation was not being disabled when selecting a different clip.
  • Adding a lock when updating the JSON of a Timeline (or remapping it), so nobody can request frames while everything is changing. Seems much more stable during live preview.
  • Fixing invalid cache after editing effect in a clip, and frame accuracy (converting timestamps into frame numbers). This makes frame by frame editing much better.
  • Fixing broken gravity for GRAVITY_BOTTOM_LEFT
  • Fixed bug with Build server version detection regex (when releasing new versions).
  • Fixed a big bug when pasting deleted clips and transitions.
  • Refactoring some tracking code on initial install, and saving settings after launch (since some settings are updated on launch)
  • Always settings unique id when sending metrics, which is required or analytics ignores it
  • Fixing a crash during initialization of the main window, and a crash during application exit, where threads were not being terminated correctly or safely.
  • Fixed a crash when closing the Split Clip dialog.
  • Fix align_x bug in newer Blender versions (Thanks mixedbredie)
  • Updating Blender compatibility to 2.78, since the API has changed a bit. Also fixing the regex for detecting preview images from Blender, since the output from Blender is now a bit different.
  • Refactoring load project flow to take advantage of the new locks in libopenshot (which allow for quicker updates to the live preview after a change is made).
  • Fixed a regression detecting missing files that contain expressions (like blender animations).
  • Improve speed on Transform method, since it gets called quite often during project load (due to clearing selected clips and transitions)
  • Fixing regression with slicing clips (and razor tool).
  • Fixing regression on reading large log files (causing slow launch)
  • Fixing regression on passing keypresses to timeline. CTRL and SHIFT keys have special uses on the timeline.
  • Improve cutting/splitting dialog to use Timeline() object, to support all possible media types (images, videos, etc...) and maintain correct aspect ratio.
  • Removing unused files and unneeded translatable strings. Also, adding title names to translation template (forgot about those).
  • Removing old effect meta data and old effect icons. New effects will have different translatable metadata.
  • Removing uploads folder from mac build script
  • Removing app.processEvents from transitions and effects models, due to crashes on OS X. Also, it doesn't make much of a difference anymore.
  • Fixing weird bug preventing backup.osp from restoring correctly
  • Fixing bug with duplicate title when running in an non-English language
  • Improving logic to process files when importing (some were incorrectly marked as invalid)
  • Fixing bug when opening legacy projects (1.4.3) that contain effects or markers

Requirements:

  • Python
  • GStreamer
  • gtk+
  • GooCanvas
  • MLT Framework
