Kdenlive 21.04 released
by Farid Abdelnour | Apr 27, 2021 | News, Releases, Uncategorized | 0 comments

Windows: Uninstall old version. Then install version 21.04.0.

The Kdenlive team is happy to announce the release of version 21.04 with lots of interface and usability improvements and many bug fixes. This version also comes with new Typewriter and Strobing effects as well as Effect Zones, which give you the ability to apply effects to track and/or timeline regions. There is also new Speech-to-Text feature to automatically transcode audio to text and a Media Browser widget to easily browse and add your source material to your project. The Online Resources has been converted into a widget and buffed with more media providers. Not to mention tons of under the hood polishing in preparation for Qt6 and MLT7.

We would like to thank the contributions of Rafal Lalik (Typewriter effect), Vivek Yadav (Media Browser), Martin Sandsmark (Alpha Strobe effect) and Julius Künzel (Online Resources), and also welcome Julius as a core team member. While the devs were busy hacking the bug squashing team managed to close these past months more than 500 bugs in the tracker.
Speech to text
The new Speech to Text feature allows to automatically transcribe any audio to text using the Vosk speech recognition toolkit. Currently there is support for 17 languages and dialects using the official models. Download the model and add it as a dictionary in the settings or simply drag and drop it.
You can find more information on how to install the needed dependencies and speech models in the user manual.
Interface and Usability Improvements
This cycle received a good amount of interface and usability improvements.

Zoombars
Besides the availability of zoombars in the monitor and keyframe scroll bars, zoombars are now available in the timeline as well. You can easily zoom in/out in the timeline by dragging the edges of the timeline scrollbar. (Vertical zoombars coming soon.)
Key binding information
Key binding info has been added on the left while context item information has been moved to the right of the status bar.
Improved timeline visuals
The timeline got a visual overhaul with more and better looking guides/marker colors, the guides have been moved above the timeline ruler while preview and zone bars have been moved below.

New Media Browser
The new Media Browser allows you to easily navigate through your file system and add clips directly to the Bin or Timeline. You can enable it from View menu.
Improved Keyframe panel
The effect’s keyframe panel has new icons, improved keyframe grabbing and new functions like:
Move a selected keyframe to cursor

Duplicate a selected keyframe

Apply a value to selected keyframe(s)
Select keyframes with CTRL + click

Rubber select select keyframes with SHIFT + click

Move multiple keyframes at once
Effects
Besides the new shiny features a lot of enhancements have been added as well like the ability to delete all effects in selected clips, ability to download LUTs directly from the interface, added Drop Area to “Master” button to drop effects to it and polishing the rotoscoping monitor overlay to name a few.

Typewriter
The beloved typewriter effect is back with a vengeance with 3 animation modes.
Animation by character
Animation by word
Animation by line

Alpha Strobe The Alpha Strobe effect can be applied to text, images or videos.

Above the effect applied to a text clip. On the right the effect applied to a video track.
Effect Zones
The new Effect Zones allow you to apply effects to specific regions of tracks or the timeline. Zones can be set from the effect zone bar in the timeline or from the interface in the effect panel.

Online Resources
The new online resources widget features more source footage providers such as Pixabay and Pexels besides the already available Freesound and Internet Archive. Other possible providers are being considered, see here for more details.
It is important to give credit of the downloaded sources so we’ve added an option to directly import the license attribution as a project note.
