Kdenlive 21.08 is out

by Farid Abdelnour | Aug 16, 2021 | News, Releases | 62 comments

Kdenlive 21.08 is out with an upgraded engine, bug fixes and many interface and usability improvements. Although the highlights are mostly under the hood we managed to add some nifty new features as well. This version now requires MLT7, which comes with a new time remapping feature and a more stable and concise code base. (MLT7 sets the foundation for long awaited features like GPU processing, multicore support and improved color management to name a few, all expected in MLT8.)

IMPORTANT
The Automask effect has been removed in MLT7 (along with many other legacy and buggy modules) but it will eventually be replaced with more powerful OpenCV tools. The Region module is also removed and it has been replaced with a new Effect Masking feature. Taking the opportunity of these changes we have also cleaned up the code base and removed old and unmaintained tools like the DVD Wizard (yes, some people still used it) and the Preview Compositing mode.

We do not recommend to open old projects with Kdenlive 21.08 due to the aforementioned changes.

Performance

We continue with every release to improve performance and with this version the Jobs Processing code has been completely refactored fixing an interface lag/freeze when importing hundreds of files and hundreds of gigabytes at once. Also panning through the timeline has a more fluid and smoother experience due to recent changes.

Time Remapping (Speed Ramps)

The new Time Remap feature allows to keyframe the speed of a clip.

Masking Effects

You may now apply effects to only affect specific regions of a clip by using masks. Do note that this is only the initial implementation so expect an improved workflow in the coming releases. For now the process involves 3 steps:

Add one of the 3 available masks: Shape alpha (mask), Rotoscoping (mask) or Alpha shapes (mask).
Add an effect (or effects) to be applied to the masked region.
Add Mask Apply to activate the mask to the effects in step 2.

You may apply more than one mask per clip by following the same 3 step process.

Interface and Usability Improvements

Move Guides with Spacer Tool
Easily moves Guides along with clips using the Spacer Tool by using the new Guides Locked option.

Raise widgets with shortcuts
Added ability to assign shortcuts to raise dock widgets.

Shortcuts for keyframe functions
Added ability to assign shortcuts to 3 keyframe functions: Add/Remove Keyframe, Go to next keyframe and Go to previous keyframe.

Same track transitions improvements
Added additional options to the same track transitions: Duration, Reverse and Alignment.

Command Bar
The command bar allows to easily search for any action in Kdenlive like changing themes, adding effects, opening files and more. It can be accessed with the shortcut: Ctrl + Alt + i. (This feature requires KDE Frameworks lib version 5.83)

Copy value at cursor position to clipboard
In addition to the Copy Keyframes to clipboard, the new Copy value at cursor position to clipboard option allows to copy only the current value to a single keyframe.

New mapping modes and options when importing tracked data
Inverted Position and Offset Position are two new mapping modes for importing data from the motion tracker. Inverted position behaves like the current Position function but inverts the imported x and y values. Offset Position can be used for footage stabilization since it imports the difference between the first keyframe position (reference point) and the current keyframe position. Also new mapping locations were added: Top left, Center, Bottom right.

Rename guides from monitor
Clicking on a guide in the Project monitors allows to easily rename it.

Other fixes

Titler: When editing a title clip there is a new Add as new title option.
Add option to go to start if playback started on timeline end
Fix audio thumbs for multistream clips
Show markers thumbnails on hover in clip monitor

This version could have been a great one but Fade In/Fade Out video effects are totally broken, unusable. Try them, you’ll see what I mean. We see the video clip in pink and green during the effect. Since I use these effects a lot, I can’t use this Appimage version. I have to stick to 21.04.03b.

BTW, this is only an Appimage version problem since the Windows version is fine. Furthermore, I’ve noticed this problem began several days ago in the Daily builds.

I am very disappointed because I was waiting for the Time Remapping for a long time. But I will have to wait to the next version until this problem is resolved.

I’m on OpenSuse Tumbleweed with mlt 7.0.1-2.1.

Thank you.

I don’t know if I missed an update or anything but the last time I used this, there was this category tab near the top right (editing, audio, colors, etc.). It’s gone now. Was that removed or do I just need to toggle it back on? I can’t find the relevant option…

    I used the Flatpak on KDE Neon straight from Discover. I was able to bring back the functionality by adding the 5 layouts as extra toolbars but I couldn’t find the compact tab bar on the top right. Anyway, the way I have it now more closely resembles what I had in Davinci Resolve anyway so I like this toolbar implementation better. Thanks for answering anyway.

Unfortunatelly chroma key doesn’t work on linux anymore. The problem has been there in a former version and now is back.

a) the chroma key colour picker is not on the top of the drop but on the bottom
b) it picks only black or white as background

Congratulations, it seems as you guys for the first time in 20 years of attempted NLE development in Linux pulled it off. The video plays without shuddering, i can keyframe audio right in the timeline and i can stick markers to clips that then move _with_ the clips, so audio can be synced up. Sigh. These were aggravating 20 years of “how hard can it be” and hair pulling. Ironic that this happens now that there is also for the first time competition from a commercial vendor in the form of resolve.

Help! I tried to looking for an answer everywhere on the net, but speech to text does not work. I did everything constructed in the manual: installed phyton and vosk, downloaded the speechmodels (Windows 10). But I always get an error message, saying that the speech script could not be found! It also seems like, a lot of other wondows user seem to get the same error messages, not matter what they try! The Log says, that speech to text seems to be fixes, but I think there is still the bug on that!

Fade In/Out is somewhat broken in the linux repo. It behaves as if the Fade to/from Black option is checked in the Project Monitor when previewing, but renders just fine.

konatafan on August 23, 2021 at 8:37 AM

Ok. Not sure if this was a bug in the older version too, but 21.08 doesn’t like having two text clips with the “typewriter” effect next to each other. Whenever I place two text clips that have that effect close to each other (e.g. usecase: pseudo subtitle for 2 characters talking), the second text clip flashes a few frames of green.

First, and foremost: thank you for this new release! I really can feel the boost on the background engine, the overall experience is more fluid than ever. Great job! However, I also have found, that on every project opening some kind of background work starts, which one can see as pending job in the project bin (in previous versions this only happened once, when you have added a clip to the project). During which the UI is mostly unusable (although the improvement can be felt here). If I open a project with 100+ clip, it really takes ~10-20 minutes to become usable. Can this be somehow Improved? And also, if I select other method than KCF in the Motion Tracking effect, it will cause a crash. I’m on Windows 10, standalone version.Thank you again!

  Hi, I would like to thank you and say that this new version 21.08 is fantastic, for sure you are very much loved!, so thank you very much.
  I just want to point out, if I may, that when I select another option other than KCF in motion tracking kdenlive simply closes, aborts and exits. I’m a fan of the kdenlive motion tool, but being able to work only with the KCF algorithm is too bad.
  I wanted to ask from my heart that you would look at this and, as far as possible, fix it. I use Kdenlive on Windows 10 Home

FYI – Fade In/Fade Out video effects have become fully functional again on the last Daily builds (Build #1006, Aug 24) Appimage.

If you can’t wait for the next stable version, obviously 🙂

One word : YES!!!

Thank you very much Kdenlive team!

What do you mean by “modern” transitions? Transitions are mostly stocked in “Wipe Method”. If you want to add more, click on the rightmost icon to Wipe Method; this will open the Kdenlive Add-On Installer.

The most beautiful are the simplest in my opinion. And according to Peter McKinnon, the most beautiful transitions are those you make yourself.

Hi, I would like to thank you and say that this new version 21.08 is fantastic, for sure you are very much loved!, so thank you very much.
I just want to point out, if I may, that when I select another option other than KCF in motion tracking kdenlive simply closes, aborts and exits. I’m a fan of the kdenlive motion tool, but being able to work only with the KCF algorithm is too bad.
I wanted to ask from my heart that you would look at this and, as far as possible, fix it. I use Kdenlive on Windows 10 Home

  And I know 4 more people that the same is happening, all on the Windows 10 platform

    Thank you for reporting. Yes, we know this crash. Use KCF in motion tracking until we find a fix.

I was sad, with the new version 21.08 motion tracking stopped working… it doesn’t give an error, but it simply doesn’t analyze when you send it to analyze. It presents 1 Job but does nothing, it is not analyzing the video. I was left without a feature that I used so much, I and some people reported to me that it is no longer working with them. We are all using it on Windows 10.
sad, i was sad

Hi, this version 21.08 is fantastic, thanks for all the wonderful work you guys do.
I wanted to register that motion tracking stopped working in this version, for me and for 12 other people who reported that it also happened to them. We all use it on Windows 10
What happens is that it doesn’t analyze the video, it doesn’t give an error message, but it doesn’t do anything, it doesn’t analyze the video, you just click to analyze it and nothing happens… If you try to change the analysis algorithm, the program crashes.
I’m sad, I use motion a lot and was dying to experiment with the changes they’ve made to motion, but now it doesn’t work for me and these people anymore.
I hope it gets back up and running as soon as possible… Thanks again for Kdenlive, for the wonderful job you guys do.

  I tested on Win10 20H2 and 21H1 and the motion tracker is working. Which version of Win10 do you have?

    Hi, thanks for the help!
    I use version 21H1, I always keep the OS up to date… The funny thing is that it always worked and I love kdenlive’s motion tracking, although whenever I tried to change the algorithm it would abruptly abort, closing, it always happened to try to change the algorithm (I saw some people commenting that too, about changing the algorithm). As I use it a lot, some people came to ask me about it because the same thing was happening to them… As I always recommend and promote Kdenlive to friends, relatives and other people, a lot of people use kdenlive too and come to looking for me to find out if this was happening to me. I hadn’t tested it yet, I had seen the changes, I was dying to test it, but I still hadn’t had the opportunity. There were about 12 people, but today 3 more came to me for the same reason.
    So I ran to test it and it’s happening to me too. It doesn’t give an error, it doesn’t crash, it just doesn’t analyze the video, it doesn’t create the keyframes, you click the analyze button, it reacts normally, a 1 Job message flashes fast in the upper left corner and that’s it. I use it a lot and some of the people I mentioned also use this tool a lot. I was very sad, not so much because I really use and need it, but because I really like kdenlive motion tracking, I’m a fan of this tool, you guys had the courage to create, develop and keep improving this tool and it does a great job. I’m very sad, but needing to do the tracking manually, I just wanted to see this tool always perfect, because really you did and are making this tool even better. Ahh yes, everyone else also uses Windows 10 version 21H1.
    Thanks for trying to help!

      I downloaded a build last night but haven’t installed it yet. Do you think you can solve the problem if I install this build?

        I installed build 867 but unfortunately both problems remain. Motion tracking does nothing and does not generate the data and if you change the algorithm kdenlive aborts

        All video drivers updated? Sometimes Kdenlive have weird issues when the video driver is not updated.
        
        What you can try is to reset Kdenlive. Go to help -> reset configuration.
        
        Here some more details for deleting the kdenliverc file which contains the basic settings: https://userbase.kde.org/Kdenlive/Manual/Windows_Issues#Cannot_open_projects_made_with_previous_version.2C_timeline_snaps_back.2C_cannot_import_clip

        Hello my friend!
        Yes, the video drivers are up to date, I even have the Intel® Driver & Support Assistant installed and I’ve never had any problems with motion tracking other than changing the algorithm. I was reading in the repository that this problem was already known among the developers, I just couldn’t identify if they had already fixed it or not, I know that the bug of aborting kdenlive when trying to change the algorithm still persisted, it was reported on 21.08
        Unfortunately my friend, resetting didn’t work here for me, two people already told me it didn’t work for them either, I’m waiting for other people to tell me if it worked or not for them. Thank you so much for trying to help.

Hi, my problem is that quite often my program crashes. I cannot add any more clips and music. Even reinstallation doesn’t help

  Give more details like which OS, AppImage, Flatpak, distro package, .exe? What are you doing when this happens?

Junior on August 30, 2021 at 12:52 AM

I have the windows version of kdenlive 21.08.0.exe
I open the program, add files to the library and sometimes no music, picture or video files can be dragged onto the axis. Sometimes it helps to turn off the program and you can work, but then after some time you cannot add more parts again

  Difficult to help. I guess you are working on Win10. Download the standalone version to see if happens as well.

why when I want to suppress the rendering process, it doesn’t show the estimated time when it will finish?

Setup wizard show “missing package «Frei0r effects» (frei0r-plugins)”. Is this an appimage problem, or do I need to deal with my system?

  Thank you for reporting. Yes, the Frei0r effects are missing. This issue should be solved with the upcoming version 21.08.1.

SO glad to see this feature! I was testing it out and noticed that there seems to be an issue on Windows 10 with Rendering. I’ve been using MP4, but keep seeing weird interpolation when the time remapping effect is applied. Hoping this can be fixed because I would love to use this!

Hi, I’m using the stabilization feature extensively, but it is (and was eversince) very tricky to use effectively: although I have a proxy file for a clip, if I stablize it, it will use the original clip for the process, and the resultant .mlt will also use the original file, which means when dragged on timeline, it will play very slowly. So as a workaround, I have to stabilize the original clip in a dedicated timeline, render it out, and use the rendered clip in the intended project. Could you please make the stabilization to use the proxy, if it is enabled on a clip? Than at export the stabilizition .trf file can be used on the original clip. Could you please make this change in a future version?

Any way of adding 18fps, need it to convert old 18fps movie films.

  When you add a clip to Kdenlive for the first time it will ask you to adapt the project to the clip’s fps and resolution. Otherwise you can just go to menu Project -> Project Settings and there you can create a new profile. (See if you can find it.)
