Kdenlive 20.08 is out

by Farid Abdelnour | Aug 17, 2020 | News, Releases, Uncategorized | 70 comments

Kdenlive 20.08 is out with nifty features like Interface Layouts, Multiple Audio Stream support, Cached data management and Zoombars in the Clip Monitor and Effects Panel but one may argue that the highlights of this release are stability and interface improvements. This version received a total of 284 commits with some major contributions from new developers. (Thanks Simon and Julius)

Under the hood

A major refactoring of the project file fixes a long standing issue with the decimal separator (comma/point) conflict causing many crashes.

Projects created with 20.08 forward are not backwards compatible, that is, you won’t be able to open your .kdenlive project files with older versions.

This version also brings a performance boost to audio thumbnail generation as well as JPG image sequence playback.

New interface layouts

These workspaces aim to improve the layout for each stage of video production:

Logging for reviewing your footage
Editing to compose your story in the timeline
Audio for mixing and adjusting your audio
Effects for adding effects
Color for adjusting and color grading

Check out this video for more details.

Note: Video scopes do not work with DirectX under Windows.

Audio

This version brings the initial step in implementing an advanced audio workflow by adding multiple audio stream support. In the next releases expect audio routing and channel mapping as well. The mixer got a facelift making it more efficient in smaller heights.

Zoom bars

Effects panel

Adjusting keyframes just got easier.

Clip monitor

The Clip Monitor also received zoom bars. Also notice the interface improvements like seeking when dragging, new layout ruler, improved overlay sizes (fps, timecode, etc).

Cache management

A new cache management interface under settings allows you to maintain and control the size of your cached and proxied files as well as backup-ed data. You may also clean data older than a specified amount of months.

New shortcuts

‘ (Apostrophe) to set audio stream to target track.
Shift + Alt as alternate shortcut to move single clip to another track.
Alt + mouse Windows specific shortcut to change a grouped clip’s track (Alt+mouse).
. + number to focus on Video tracks (i.e: . + 1 focus on video track 1)
alt + number to focus on audio tracks (i.e: alt + 2 focus on audio track 2)
( snaps beginning of clip to cursor in the timeline
) snaps end of clip to cursor in the timeline

Miscellaneous improvements

Project notes: allow creating markers from timestamps and assign timestamps to current bin clip.
Added option to always display clip monitor audio thumbs below video instead of an overlay.
Composite transitions with Lumas.
Add a “Save Copy” action to save a project copy.
Project bin improvements: Expand/collapse all bin folders with Shift+click, remember folder status (expanded/collapsed) on save, and many other fixes.
Add clip length adjustment to speed dialog.
Titler: add option to save title and add to project in in one pass (through the create button menu.
Add proxy icon to clips in timeline.
Increase monitor audio thumb resolution.
Ability to change colors of audio thumbnails (Go to Settings > Configure > Colors).
Renamed “Add Slideshow Clip” to “Add Image Sequence”.
Clickable clip name on top of Clip Properties widget opens a file explorer to the clip’s location).
Windows: use compatible methods when dropping a folder in bin.

I’m happy to see new layout and cache management interface. Anyway, do you guys have a plan to support GPU rendering?
- farid a. on August 17, 2020 at 5:11 PM
  
  Work on the MLT, our engine, might start after the Qt6 upgrade. Unfortunately this is not a simple task and help is always welcome. 🙂

  for nvenc use:

    Does this work for you?
    - Mario Ray M. on August 18, 2020 at 6:17 PM
      
      I get similar custom option, I know it works because I use laptop with optimus tech and I use PRIME. When I use Intel only, the rendering result only contains audio, no video though it’s still a video file. While when I use Nvidia only, it’s rendered perfectly. Problem: rendering time doesn’t differ much from CPU rendering.

      In Arch linux everything works ok, also in Pop! _OS is ok, tested with video cards: nvidia gt630(model kepler 384 cuda), nvidia gtx 660, nvidia gtx 1050ti, nvidia quadro k2000m. Maybe in Kubuntu working but other distro not tested but most other distributions don’t work. Tested cbr nvenc is ok: f=mp4 vcodec=nvenc_h264 vb=14000k rc=cbr acodec=aac ab=128k . Tested with vaapi on intel generation 3 is ok: i3 3240, i5 3320m , i5 3470, i7 3770 – f=mp4 hwaccel=vaapi hwaccel_device=renderD129 hwaccel_output_format=vaapi vcodec=h264_vaapi vb=30000k acodec=aac ab=192k .
      Everything I mentioned encodes with gpu on h264, but gtx 1050ti also works in h265 (f=mp4 vcodec=hevc_nvenc vb=30000k acodec=aac ab=192k). Also in Manjaro it was ok a short time ago but now not that they modified ffmpeg to update. Appimage not working, only v18 appimage only with nvenc, no vaapi every-time. nvenc & vaapi work only installed version, no appimage*(exception only v18 work appimage)

  I love new ui and most feature update.. btw i can’t find render button ?
NEOAethyr on August 17, 2020 at 6:17 PM

I wish the monitor on the right would stay it’s size after another run.
It drives me a little nuts resizing it every time I open the app.

As a side note, mlt/melt.
I can’t get an output anymore, I get the audio, just no video.
It’s effected me on ubuntu 19.10 and 20.04, I think it last worked on 19.04, or maybe it was 18.10.
Kdenlive displays the video though.
Using nvidia’s drivers.

I’d like to beable to pipe a mlt file or project file into mpv, so I can see the actual outcome before I go and render it to a file later.
I know it’s possible, I’ve done with with streams and tee.
Heck in that sense I wouldn’t even need kdenlive to render and compress.
I think it’s possible with a custom melt and ffmpeg compile with avformat support but I’m not sure yet.
- Apas on August 17, 2020 at 9:50 PM
  
  Try to arrange the interface as you like and then save the custom layout and turn off the program. When you start it next time – it should load exactly the same interface layout. But if for some reason this didn’t happen – just switch to your favorite layout using Load Layout function. This works fine in my case…
Robert Konigsberg on August 17, 2020 at 6:22 PM

I was just dealing with minor keyframe adjustments, so this is good news. Thanks!
stefan on August 17, 2020 at 7:47 PM

Hi
Thank you guys for this amazing software.
I really appreciate the work everyone puts into kdenlive.

note: small mistake in kdenlive 20.08
I will add a saturation filter to the color clip, the display in the project is OK .Render to file.
Finished clip is white and black.

OS: win 10
- Merlimau on August 18, 2020 at 5:34 PM
  
  Disable “parallel processing” in the render window and try again.
  - stefan on August 19, 2020 at 9:39 AM
    
    it doesn’t help
    the finished clip is still white and black
    - Merlimau on August 20, 2020 at 9:38 PM
      
      Thank you for reporting. This is a Win10 bug. The effect vignette has a similar issue. Which Win10 do you run? 2004? It doesn’t happen on Win7.
      - stefan on August 21, 2020 at 10:55 AM

        in Kdenlive 20.04.1 is everything OK
Kerry on August 18, 2020 at 8:22 AM

Guys, please fix the issue with the Ut Video preset in the Render options for lossless. It does not export as Ut Video. It exports as some small lossy file. This has been a problem since that Ut Video preset was first introduced and it hasn’t been fixed yet not even in this newly released version.
Tim on August 18, 2020 at 10:06 AM

This is straight awesomeness! Thank you <3
Shiba on August 18, 2020 at 10:28 AM

I’m sorry, how do I get the zoom bar on the clip monitor? ?
- Merlimau on August 18, 2020 at 5:30 PM
  
  In the clip monitor: hover with the mouse below the video, CTRL+MouseWheel zooms in.
  - Shiba on August 18, 2020 at 6:38 PM
    
    Ah! Thanks ?
    Isn’t it a bit hard to discover however? ?
Rod on August 19, 2020 at 4:40 AM

Just loaded up 20.08 from the PPA in Linux Mint 20 Ulyana Mate. So far the functionality seems the same but the display is horrid. I am missing all of the dark themes and most of the icons for the existing themes so I have large text buttons instead. Is there a way to download the missing themes so I can integrate them? I can’t seem to find the ‘find upgrades’ or such button.
- farid a. on August 19, 2020 at 3:32 PM
  
  Just use the AppImage…
- Vincent Pinon on August 19, 2020 at 9:52 PM

  Submitted merge to add these profiles to the nightly builds so people can test once they are in. https://invent.kde.org/multimedia/kdenlive/-/commit/d794fa69a93323f726f8817b23e889bc7c09b074
  
  Maybe we can ship them for 20.12 if they work well for users.

Jim C. on August 19, 2020 at 7:58 PM

Great Job guys, love it, and thx for another great release!
Also I have a question: Is it possible to have more then just V1, V2 A1 and A2. Also having a default name for the Vs and As on start up. I like on start to have 1s named Primary and 2s named Secondary also have more Vs and As like having a base template on start up. I know how to add but it would be nice to have them already there when I start a new project. Again Many Thanks.
- farid a. on August 20, 2020 at 6:32 PM
  
  In the settings panel you can go to the “Project Defaults” option and set the amount of audio and video tracks. But you can’t just have a set name.

Firstly, thanks for the awesome software. Kdenive simply an amazing tool. Now my doubt is: how I make to let my audio tracks waveforms with the same visual layout in Windows version than the same of photos of this new version posted here?
- Merlimau on August 21, 2020 at 7:48 PM
  
  In the timeline -> right click on an audio track head (most left, where the icons are) -> enable Separate Channels

  View -> manage layout -> on the bottom the right most icon with the 2 circle arrow.
thaylorpeter on August 24, 2020 at 11:52 PM

Thank you for your hard work! Could you please make it possible, to change multiple clips properties to use full luma range at once (just liket it is possible with proxy generation, using right click menu)? Now I’m only able to change it clip by clip, which could take a lot of time considering 300+ clips. Thanks in advance.
James Regenold on August 25, 2020 at 7:19 AM

I very much would like to report problems and bugs, but the KDE login system is so bad, that
it is impossible for me to register or recover my KDE account. At this point, I can’t report things that
I find. I’ve lost interest in trying. The KDE process is overkill for a simple bug reporting system.

Example: I want to reset my password, it wants my name and email address. Then it says name is associated with the account.
doesn’t match. Why should that even matter if I was previously logged on with that email address? It’s retarded. Also the Captcha stuff is ridiculous, it always asks more than once ..

Kdenlive needs a bug reporting system that is simple and is divorced from the overly complex KDE system.
mac on August 26, 2020 at 2:23 AM

Windows 20.08.0: “Motion Tracker” works perfectly well in “preview mode” (i.e. without clicking “Analyse” the red rectangle follows the originally selected area very well). However, after pressing “Analyse” and waiting for a long time, the red rectangle moves unpredictably. It seems like it moves out of sync with the movement in the video (but it does move, so perhaps some data have been gathered). I tried various offsets in an attempt to sync both movements, but did not succeed. “Keyframe spacing” does not influence this incorrect behavior. I also tried 5 algorithms, none worked well (but the “preview mode” did work well).

Obviously, when importing the data from clipboard to some other object keyframes, the other object also moves unpredictably, with no relation to the originally selected area.
Faruq Abdillah on August 26, 2020 at 10:55 AM

Tomáš Hruš on August 27, 2020 at 10:01 PM

Thaks for new version!

In Windows are titles and images from the second track after rendering are shifted to another time, then in the project… Why???

- Constantin Aanicai on August 30, 2020 at 3:30 PM
  
  You need an nvidia card with nvenc support, kepler or better, I don’t know what model of video card you use. You need an operating system that supports nvidia drivers owning new versions, for example Arch Linux. The kdenlive version must be installed with pacman -S kdenlive in Arch or sudo apt install kdenlive in Ubuntu, do not use .appimage. Other versions of linux also support nvenc and new nvidia drivers but not all, I tried Kubuntu, Pop Os, Manjaro. Only kdenlive-18.04.1b-x86_64.AppImage supports nvenc encoding, other .appimage newer than v18 does not support.

Hightower on August 30, 2020 at 12:07 AM

Hello.
In previous version i have issues with applaying custom audio effects to audio track becasue his been saving with wrong parameter “customVideo” in XML-file. But custom effects stack has been applaying by the right way and i can use this stacks for video in the library.
In new version this problem fixed, but now i cant apply custom stack to video in library. Only to audio track moved from library to timeline. How i can fix this for using custom effects stack to video in libray?
Pls, sorry my bad english and maybe wrong terms, i use ukrainian iterface.

kdenlive 20.08.0-1.fc33.x86_64, crash in Fedora 33.
Lorenzo on August 31, 2020 at 2:26 AM

Hi, developers and community,
if any of you could help me, it’d be much appreciated.

Well, I always had some issues with the program on Windows 10, such as sudden crashes, but now I’m experiencing the most stressful one:
from version 20.08.0 release until now, some “corruptions” between different clips divided with the razor tool are happening after rendering.

A quick black screen gets in after the conclusion of a clip, disappears and, then, of course, takes the following clips forward. But that makes all the posterior clips out of sync with audio, besides the fact some static items added into the timeline (such as images) go away (also after the rendering).

I’m looking forward to an answer, free for questions and explanations. Thanks for the attention.
- mac on September 1, 2020 at 10:08 PM
  
  I think the most useful way would be to file a bug report, and most importantly, send your project xml source, using the (not so friendly according to James Regenold’s post above) KDE bug report system.
- Tomáš Hruš on September 3, 2020 at 1:07 PM

One thing that bothers me about the new versions of kdenlive, I can’t drag a folder with clips in the timeline, on v18 you can
Roberto on September 11, 2020 at 2:54 AM

I found a issue about VP8 encoding. In appImage 20.04 it seems fine. In version 20.08 the bitrate of video is 1/10 of previous version but the command line is the same. In the last, the quality slide bar of render window not affect the final result.

Manuel on September 11, 2020 at 8:00 AM

Same here with rendering on Windows 10. Didn’t happen with 20.04. The render just doesn’t respect the timing/cuts/effects set in the project and working fine in preview. It’s pretty much random.

Thanks @Merlimau. Just verified it’s fixed. I spent a good while last night searching for that link, hoping a nightly would fix this. You’ve just saved a classroom full of kids’ video 😀
mac on September 11, 2020 at 8:31 PM

20.08.0 on Windows: title clip “show background” does not work (or maybe it works only when creating a new clip but not when editing. This used to work in earlier versions). Also, since a long time ago, occasionally adds newlines to text when editing. Perhaps because of \r\n and \n in the project file. These tend to grow and be added and added on every save.

Would be great if kdenlive had unit tests. This would save us from three steps forward, one step back on every release due to regressions, and users always looking for this single version that luckily has just the working set of features that you need.
Tiago H on September 13, 2020 at 5:36 AM

Thanks for the great job!
Does version 20.08 work with GPU on WIN10? GPU seems not to be detected or used!
Some effects deteriorate playback performance, playbacks become choppy.

Thanks!!!!

alex on September 18, 2020 at 3:02 PM

This is AWESOOOMMMEEEE!!!
I was getting frustrated by lost of minor things and often crashes in kdenlive but I’ve been working on the new version the past couple of days and edited a vid with 99% no problems or frustration!

Layouts make features more prominent and easily discoverable and make the workflow GREAT!!! Crashes are almost non-existent (only had some when trying to disable the proxy from some vids to get a better resolution for the fine-details)

Only *minor* issues
– re-ordering layouts doesn’t seem to work.. Any changes through View -> Manage layouts seem to randomly scramble the layouts order. (I can still use View->Load layout but the shortcuts on the top right would be faster)
– would it be possible to make resizing of panels stick between switching from one layout to another? (reset to default when restarting the app but keep the resized ones when switching during the session)

I was looking for alternatives but instead I will now send out a donation as a result of how happy I am and how frictionless my last edit was!
Keep up the good work <3
Arnaud on October 4, 2020 at 2:36 AM

Hi,
Thanks for this great release.
I have a question though: how do I reset the layout to the “normal”/default one. I clicked by mistake on the layout buttons (top right) and it changed everything. I tried the reset button in “manage layout” but it does nothing (at least nothing to the layout). I tried removing all layouts but the box is repopulated with the default list.
I’m sure they are great layouts to work with, but as all things with production software: change must be done over time and clearly I’m a lot less productive with that layout, I have a big screen and liked a lot the default layout from previous versions.
I like how the layout change is not forced upon us but having the default view in the default list of layouts would have been nice.
- Merlimau on October 5, 2020 at 4:24 PM
  
  Arrange the layout as you like. View -> save layout -> give a name as you like. Then view -> manage layouts -> move your saved layout with the up/down arrow “triangle” on the top place. Now your layout is on top right on the first position.
