Kdenlive 20.12 is out!

by | Dec 21, 2020 | News, Releases | 80 comments

The team is happy to announce Kdenlive 20.12 release bringing exciting new features like same track transitions, subtitling tool, an overhauled effects layout and the usual batch of bug fixes and usability improvements. Work was done on performance optimizations (by Martin Tobias Holmedahl Sandsmark) resulting in a snappier timeline, improved thumbnail creation and faster project opening.

Same track transitions

The long requested same track transition feature has finally landed in this release drastically improving the editing workflow. It can be activated by selecting a clip and pressing the u or via the icon in the timeline toolbar. (There is a known issue where it doesn’t work in an effect is applied to the track. Will be fixed in next month’s release)

Subtitling tool

The new subtitling tool allows you to add and edit subtitles directly in the timeline on a special subtitle track or by using the new subtitle widget. You can also import (SRT/ASS) and export (SRT) subtitles. This work was implemented by Sashmita Raghav as part of GSOC.

Pro tip: It is not yet implemented in the interface but you can change the style of the subtitles using html tags like <font color=#ffff00> for setting the font color to yellow.

There is a known issue with special characters not working properly, will be fixed in next month’s release.
Subtitle track hide and lock will come in 20.12.1.

Effects

All effects have been organized under a clear and comprehensive category* structure for a better experience. Under the hood, all effects were and had their parameters updated accordingly. Nonworking or buggy effects have been moved under the Deprecated category for backwards compatibility but will eventually be removed in future releases, avoid using them.
* Available audio effects depends on the OS

Another usability improvement is the ability to rename and add/edit the description of custom effects (by new contributor Vivek Yadav.)

New Pillar Echo effect for your vertical videos.

Crop by padding effect can now be keyframed.

New VR 360 and 3D effects for working with 360º and 3D stereoscopic footage.

New Video Equalizer for adjusting image brightness, contrast, saturation and gamma.

Usability

Besides the snappier performance due to optimizations, the timeline also received a usability boost. Clips in the timeline change color according to their tag in the project bin. (This affects all clips in a folder as well.)

 

Ability to enable/disable normalization of audio thumbnails from track header

Ability to delete multiple tracks at once (by Pushkar Kukde)

When archiving a project an option was added to archive only clips in the timeline as well as the option choose the compression method between TAR and ZIP.

On the backend front the Online Resources tool was ported to qtwebengine (by Andreas Sturmlechner) and downloading wipes, render profiles, titles and wipes defaults to using https.

What’s next?

The main features planned by the team for 2021 are Nested timelines, Advanced trimming tools and Audio Routing and Channel Mapping. We hope to see improvement in hardware acceleration and GPU support from recent work started in MLT, our engine, you can follow the progress here. A very exiting feature worth keeping an eye on is the recent work by Tobias Fleischer in integrating GMIC effects to video editing tools (including Kdenlive via the freIOr module). Community member Hörmet has managed to build Kdenlive on a Mac and got it to render. There are still some issues like Icons are not working.

    as the zoombar been incorporated into all timeline windows yet

    Nope. Come on guys, you manged to add a zoombar, but only for effects, a few versions ago. Is it really that hard to have that feature for the clip /project monitor and sequence editor as I’ve [repeatedly requested](https://www.reddit.com/r/linux/comments/dlq6im/the_next_version_of_kdenlive_is_gonna_rock/f4ud0v4/?context=3)? It was promised then just forgotten about. It’s very difficult to video edit without this feature.

    The zoombar is a very intuitive feature where you can zoom in or out on a timeline or clip by resizing the scrollbar below the timeline or clip. Areas that need the zoombar from the last version of kdenlive were clip monitor, project monitor, and sequence editor (the effect editor already had it).

      Yes this is a cool feature but there are more important priorities at the moment. As you know, there is only one person doing most of the development so if you can’t wait then you could help make it happen.

      Go to Settings and click on Show Status Bar. There you can find the zoom in / out bar. It shows in all pages (Media, Editing, Audio, Effects, Color).
      For Clip Monitor and Project Monitor, in case you want to zoom in or out the video, you just click and hold Ctrl + Shift + Mouse Scroll and it will zoom in / out and also show a bar to go up / down and left / right.
      There is a hidden scrollbar that only shows when you go with the mouse at the bottom of the page and you can navigate the timeline by scrubbing it left and right.

      I hope that helps

    So awesome. I am currently working on a hours long documentary and I am editing it in Kdenlive. Using Kdenlive for 4-5 years now. Thank you people!

    As a side note: would be super useful if video effects would be labeled in a visual manner as well. Like have the same Box or Pattern, and the video effect to show it based on how it would apply to it. Imagine the white letter A on a red and blue background, in a boxed-sized icon. The blur effect will show it blurry, the desaturate as desaturate, and so on. Hover with the mouse over it to see it in action maybe. You know what I mean? Several video editors have this useful addition.

    Really good release and great work! I’ve been using Kdenlive for many years now and it’s amazing to see how it went from a quirky video editor to a (as I see it) professional tool.

    I am missing the VR 360 effects in the effects list on Linux. Is there a need to install additional components to make this work?

    Wow! That’s awesome to see all these amazing new features! Thank you so much for adding the colorful timeline options for the clips! Now it can be a beautiful timeline to work on! Maybe in the future add more colors? 😀 The subtitles are also very handy!

    Well done to all the developers and may you all continue to do even better in the future!

    You should also add in the features information that Kdenlive can open, playback, and render out 10-bit videos (without the need to transcode) because I was able to do so. As well HEVC (h.265) opened without any problems and no transcoding was needed. I just had to decrease the playback resolution and that was it. I’m happy for this usability for high-end videos.

    Thank you and have a blessed new year!

    Mix Clips (u) and Edit Subtitle Tool are not shown by default on the Timeline Toolbar. I found a way by right clicking on it and choosing the option “Configure Toolbars.” Then by searching I found the new Same Track Transition widget (Mix Clips) and also the widget (Edit Subtitle Tool) that when clicked it shows and hides the Subtitle track.

    Thanks! Well-thought out updates! I’ve used Kdenlive for less than a year, and remain very impressed with its intuitiveness, flexibility and stability in Windows, as well as the frequency of excellent updates. So I feel guilty making my next comment. Unfortunately, I still must revert back to Hitfilm Express when I need motion tracking. Kdenlive tracks well, but the absence of an ability to globally adjust overlay size and to individually adjust overlay location and rotation with keyframes is a limitation for me. For short clips I can do a manual overlay in Kdenlive, adjusting keyframes one at a time. For longer clips, I have to go elsewhere. I’d welcome more comprehensive motion tracking adjustments in Kdenlive. If I were more technically adept I’d offer to help. Thanks again!

        To apply the same track transition: The clips need at the cut position a half of a second spare frame. So shorten the clips on both side at the cut by half of a second.

    I like the steady development on kdenlive. But unfortunaly there are arraising bugs after bug since version 20.08.01. I’m not able to use the later versions. 🙁
    – Timeline position marker torn up (displayed incorrectly) (2/21 zoom)
    – while scrubbing around, the video is previwed in positiv time even if i move the playhead to the left
    – changing projekt profile crashes kdenlive
    – pressing “new” (projekt) after starting kdenlive chrashes immidiatly
    – clip-Monitor after clicking an Audio-Files crashes the program
    – (whish of new feature: A time messurement tool or a display for the duration of the currently markted segment)

    The new features maight be very nice but i can’t use them.

    Have a nice Christmas time whereever you are 🙂

      I did on Linux Mint 19.3 but some things did not go right. First, the took me some time to find the tool because its shortcut for some reason is not appearing on the menu. I was able to put it in a place that I could use it (and now, I can work with it)
      Regarding the function, being available you type, but the subtitles don’t appear in the video itself. I think this is a Linux thing because, While looking at the given example here above (the demo) there are two buttons: The “show/hide” and “Lock/Unlock”. On Linux Mint, they are missing. I have heard people who use Windows saying that “It is working just fine” but for Linux Mint (19.3) users those items are missing.

    I don’t mean make big bubble buttons. Just take a look at Tahoma and what they did with openToonz it’s clear and easy on the eyes to look at.

    Same track transitions! Thank you so much. This has literally been the one and only thing I have missed from other NLEs. So much cleaner this way and keeps tracks manageable. So important when you for instance wanted to insert another clip in between two existing, but need to transition, really needed a third track. Not anymore.

    Thanks a great lot for further developing and improving this nice application,
    However seems this version has got some bug I never saw before:
    I imported an avi clip into an empty project, inserted it as is into timeline and tried to play it from an arbitrary point.
    1. It took longer than I was used to, before it started playing.
    2. way way worse – as I clicked over the timeline to set the cursor to a different time point and continue playing from there, the sound and video tracks played _desynchronized_ from there on. Something seems very wrong there.

      There are some other bugs with multible audio tracks and changing project format.
      I tried reinstalling several time but it did not work. Maybe my Windows 10 with not all updates is one reason for that. But in the end that should not matter :/

      Nevertheless due to the eazy installing process i will not give up and test every new version 🙂

      Better controls maybe come, but yet you can already style your subtitles with html. Try this text in a subtitle item:

      You can even change the color or size with html tags.
