Versie 2.2.0 van OpenShot Video Editor is beschikbaar gekomen. OpenShot Video Editor is een opensourcevideo-editor voor Linux, en vanaf versie 2.0 ook voor Windows en macOS. Het programma is gemaakt met Python, GTK en het MLT Framework, en is te vergelijken met Windows Movie Maker of Apples iMovie. De belangrijkste verbeteringen in deze uitgave zijn hieronder op een rijtje gezet:
OpenShot 2.2 Released | 4K Video Editing!
Happy Holidays to all the OpenShot supporters around the world! I am very proud to announce the latest and greatest release of OpenShot (version 2.2) has just arrived, and is ready to edit all your holiday videos! It’s faster, more stable, and better than ever!
Performance / Caching
Over the past few months, improvements to performance have been my top priority. In some cases, performance is improved more than 10x compared to OpenShot 2.1. Adding huge images to your timeline is now fully optimized, and won’t slow you down. Editing HD videos (5K, 4K, 2.5K, and 1080p) is vastly improved. A new caching engine was built from the ground up, and supports both memory and disk back-ends, depending on the user’s needs. This can be configured in the Preferences, under “Cache”. Also, opening huge projects (with hundreds of files / clips) has been optimized and is up to 10x faster.
Many critical bugs have been fixed related to seeking, missing frame detection, and AVPacket scope, which results in a much more stable engine, especially on slower systems. Also, compatibility has been improved for Linux AppImage and OS X (10.9+) App Bundles.
Keyframes are used in the animation system in OpenShot, and have received some major upgrades. Support for CSS syntax (quadratic bezier curves) now allows a %-based approach to setting the curve handles. This is very useful, and better than the previously hard-coded values. Also, 28 curve presets have been added for common things like ease-in/out, bounce, etc… Many other improvements have been made to Keyframes, such as better undo/redo support when dragging property values (in the property editor), rendering color keyframes on the timeline, and improved frame detection when using the property editor (i.e. adding a keyframe for the currently selected frame).
Error Handling / Reporting
Our library (libopenshot) and Python UI (openshot-qt) have improved error handling, and can now detect stack-traces for crashes and exceptions (on Linux, Mac, and Windows). Not only can it pull out the stack-trace, but it can send that anonymously to the OpenShot website back-end, so I can quickly identify where crashes are happening and more quickly fix them. In other words, OpenShot 2.2 now has real-time error reporting, which I’m really excited about. This can be disabled in the preferences, along with metric reporting. It also contains no personal information, just a basic stack trace of what function crashed.
New Title Templates
Many Kickstarter backers requested new title templates to be added to OpenShot. I am proud to announce that all new titles are now included in OpenShot 2.2. We have some really nice additions, such as Film Ratings, TV Ratings (small corner rating), and more!
One of the most challenging aspects of running an open-source project such as OpenShot, is the large amounts of data (downloads, installers, etc…). We had been using Amazon S3 previously, and our monthly costs skyrocketed to over $1000 just for data transfer. So, we’ve moved our installers into GitHub (which ironically happens to also be powered by S3), and our installer-related data transfer costs have gone to $0! So, a huge thanks to GitHub for being awesome!
We have also integrated torrents into our build server, and all major releases now include torrents (on our download page), to help further distribute our data transfer.
