    Hi,
    That seems very good and I start to make a video this morning with this new version but :
    Now the names of the tracks not appear.
    There is a problem and most of the time 1 frame in the timeline stay empty before a clip. It’s very difficult to move the clip at the right place.

    • Merlimau
      Merlimau on December 19, 2019 at 12:39 PM

      Do you start with an existing project or from scratch? Does your track names contain special characters?

      • Julien Rabier
        Julien Rabier on December 19, 2019 at 12:57 PM

        From scratch but now I think it’s good. I don’t know why that doing that at the beginning.
        By the way, Automated mask don’t work, no analysis data was created.

        • Merlimau
          Merlimau on December 19, 2019 at 1:29 PM

          Do you work with the AppImage 19.12.0a from the download page? Of not please do so.

          • Julien Rabier
            Julien Rabier on December 19, 2019 at 1:40 PM

            I try appimage and normal version. Both do.
            One thing awesome ! I render my video of 11min in FHD h265 and the final file is only 181mb !!! Before that was near 500mo
            I need more test about that

    Another problem, when you copy an effect from a clip or a track to another, the effect don’t work.

      How do you do copy an effect from one clip to another?

    Wow, this looks like an awesome update. Well Done!

    I’ve just installed on my ThinkPad X1 Carbon and when it opens full screen the GUI is massive in that I can only see the video/sound timelines, like it is zoomed in. If I minimize as it loads and hover over the shortcut the Win10 preview show correctly. As I then maximise it momentarily is displayed correctly then does this super zoom thing.

      • Paul
        Paul on December 20, 2019 at 5:10 PM

        @Merlimau Yes that fixed it. One has tow minimize the window as small as possible so that when the ALT-F key is pressed you can then see the dropped-down menus, then use the right arrow key to iterate through all the menus.

    You guys are amazing as always! I love this product, I do have Adobe after effect but still Kdenlive is my buddy more than 50% time.

    Hi,

    I don’t know if it was done on purpose or not but on AppImage 19.12.0a when you switch full screen on the project monitor, the clip pauses and you have to push play button to go on. The same thing happens when you turn the full screen off. It’s a little bit annoying since it wasn’t the case in previous versions.

    Thanks.

    • Merlimau
      Merlimau on December 20, 2019 at 11:03 AM

      Do you mean: playback the timeline -> move the playhead to another position -> you must press space to start playing. If so, yes this was a user request to have the same behavior as in Premiere and other editors.

    • farid a.
      farid a. on December 20, 2019 at 3:08 PM

      As Merlimau said, we switched the functionality to be equal to how industry standard programs behave.

      • Sylvain
        Sylvain on December 20, 2019 at 7:25 PM

        I see. In that case, it’s fine with me 🙂

        Thanks for the update.

    Unfortunately There is no “Speed Effect” in the motion section.
    I was of course available before.

    • farid a.
      farid a. on December 20, 2019 at 3:05 PM

      Just right click on a clip in the timeline and it will be there. It isn’t an effect anymore.

  8. Peter Freeth
    Peter Freeth on December 21, 2019 at 1:57 PM

    Great – but it still looks terrible on Ubuntu 19.10 and trying to switch to the gtk2 style always causes it to crash. ‘GLib-GObject-WARNING **: 12:56:39.588: cannot register existing type ‘GdkDisplayManager” leading to a segfault.

    • farid a.
      farid a. on December 21, 2019 at 2:10 PM

      I recommend to use the Breeze style, since it has all the icons needed.

    Great work !! Export is fast in Kdenlive 19.12 on gpu with nvenc, including effects. See two test export 1050ti & GTX660 with nvenc, pics screen & more info in the signature link.

    • farid a.
      farid a. on December 28, 2019 at 4:01 AM

      This seems to be a false positive. Can you provide maybe more information?

  11. Sylvain
    Sylvain on December 22, 2019 at 3:04 AM

    In render mode, 19.08.3b-x86_64.appimage is twice as fast as 19.12.0a-x86_64.appimage. No kidding, out of the box with no tweaking at all for both versions. I took the exact same clip with the exact same features and it took about 3 hours on 19.08.3b.appimage and over 7 hours on 19.12.0a-x86_64.appimage to render.

    I think I’ve missed something here but can not see what.

    Thanks.

    • Sylvain
      Sylvain on December 23, 2019 at 7:54 PM

      I think I found the answer. In the rendering window, in More Options check box, my Threads was at 0 in 19.12.0a but at 1 in 19.08.3b. So, if I set it to 1 in 19.12.0a, it’s now rendering at a relative same time then 19.08.3b 🙂

  12. Ryu
    Ryu on December 22, 2019 at 8:33 AM

    Copying a clip with inverted speed does not work and the waveform does not reflect the actual shape when a speed change is applied. Those are the two bug I’ve found.

    Regardless of that, really thanks for the great work you are still doing. It really is incredible.

    Kdenlive 19.12 – how to enable Hardware Encoding (NVENC)

    Kdenlive is good but you have gpu acceleration with nvidia card kepler or better, you must to install default in Manjaro Kde * (no use .appimage). Now some effects are supported by gpu and dramatically shorten the export time.

    Kdenlive 19.12 in Manjaro kde, install first time v19.08.3 – sudo pacman -S kdenlive

    After update with 19.12: To update must download on repo arch kdenlive-19.12.0-1-x86_64.pkg.tar.xz ,and click to install.

    To work with nvidia nvenc, you must have Auto Install Proprietary Driver

    How to Enable Hardware Encoding (NVENC), use f=mp4 vcodec=nvenc_h264 vb=30000k acodec=aac ab=192k, you can change bitrates as you want.

    In signature link I atached more info and 3 export test with nvidia k2000m, gtx660 and gtx1050ti.

      did not work. I have sound, not image

  14. Anton
    Anton on December 23, 2019 at 3:38 PM

    Add 700 files in multiple folders to the project and it is impossible to work. Eats memory, brakes and hangs. Not a functional project bin. You have to do a lot of unnecessary movements to select the desired clip. The application is not designed for large projects.

    • Merlimau
      Merlimau on December 23, 2019 at 6:33 PM

      Indeed, really large projects are a performance problem. With 19.12.0 we solved a big memory leakage in the timeline. Do you have an idea for a better organized project bin?

      • Anton
        Anton on December 25, 2019 at 7:10 AM

        The memory problem is not solved. Add 200 clips to the project and put them on the timeline.

        • Merlimau
          Merlimau on December 29, 2019 at 5:59 PM

          You are right. I don’t have so many clips to load. Could you make a test and post the result here? Starting Kdenlive -> see the RAM needed. Loading the project with 500 clips (FullHD or 4K?) -> see the RAM needed.

          500 placeholders (1080p25fps ) in the project bin would need 3.5GB of RAM.

        Lara M on December 27, 2019 at 10:19 AM

        Hi! I am not the OP, but I would love the ability to have a project bin where I could keep saved zones (.mlt files) even after having removed the original clips that they refer to. When editing my first step invariably is to go over all material and chop it into little chunks with descriptive names using the “save zone” feature. I would love if the project bin would allow me to keep in there all these saved zones and discard the original clips, for which I no longer have any use at all once I move on to editing after this initial triage step. Thanks for reading!

        • farid a.
          farid a. on December 28, 2019 at 4:10 AM

          Can you explain why you would want to remove the original clips? I basically do the logging/triaging by inserting zones I need to the timeline. Never used the save zones but it seems handy. To me the bin is for organizing the raw footage and the timeline is for “mounting” the footage. Do other programs behave that way? Is there a concept or paradigm? Might be interesting. Anyway, there are more nifty improvements coming to the project bin: https://invent.kde.org/kde/kdenlive/issues/287

          Feel free to comment there your request.

    God bless Kdenlive. Finally I’ve found a good open-sourced video editing software for my mac with the help of a friend

    It’s a Christmas miracle :))

      How did you manage to get it working on a mac?

    I was really impressed by version 19.04 complete overhaul, and now I’m really pleased by 19.12 AppImage. It seems to be the polished version I was hoping for, with a fully working clip monitor and Bézier curves effect. Thanks a lot for making it real!

    On Windows rotoscoping effect does not work with recent update. While I checked on 19.08.3 and 19.04.3-1.
    The problem: when I apply the rotoscoping effect the monitor is displayed as filled vertically (i.e. the clip is displayed as rotated by 180 degrees). When trying to click by left mouse button to create a region – it does not display nodes. Sometimes the image on monitors flips vertically to the right position. Then after moving mouse it maybe be flipped again and again. Then I finish to draw the region (I don’t see the nodes displayed thus I draw it in blind) by right mouse button and I try to preview/play on timeline – the rotoscoping works.
    Thus this is the problem of node selection/displaying and flipping the image on monitor in the resent version 19.12.0.

    Great work! Thanks! Master Effects is the feature I’ m waiting for. It is best for Sony s-log LUTs and other stuff 🙂

    My namesake Anton reported memory problem above. So some test for FullHD project with many clips.

    Filmed by Sony a6300. FPS: 50, Codec XAVC. Also it have some clips on timeline.
    Project Settings-> Project Files:
    Clips in project: 35 4.2 Gb
    Unused clips: 65 5.5 Gb
    Project Settings-> Cashe data:
    Audio thumbnails 2.1 Mb
    Video thumbnails 182.0 Mb

    Memory by KDE System monitor:
    Kdenlive started: 148.7 Mib
    Project loaded: 4.4 Gb (!!!)
    Project with clip placeholders: 746.1 Mib

    Thanks for making Kdenlive, it’s getting better and better! But I really miss a compressor for the audio, a compressor is essential for audio, even in films.

    Also, many of the audio plugin’s parameters show up twice with slightly different names in the properties windows. If we, for example, take the highpass filter, the frequency parameter is there twice, with the labels: “av.frequency” and “av.f” and the other parameters do also show up with long and short versions.

    I’m using Kdenlive 19.12 (AppImage) on Kubuntu 18.04.3.

      No, there is no compressor effect available. Kdenlive runs on top of MLT and unfortunately MLT has no support for Lv2 effects. If MLT would have support for Lv2 effects we could use the multiband compressor from “https://calf-studio-gear.org/doc/Multiband Compressor.html”.

      Thank you for heads up about the effects problems. Will have a look.

        Thanks for answering! 🙂

        I think it might be a workaround for these limitations. As I understand it, MLT is jack aware. So if Kdenlive connects to jack via MLT, then Kdenlive should have access to all the wonderful LADSPA, LV2 and VST plugins on the system.

        Is there any chance that you can make Kdenlive jack aware? To be able to do everything within the timeline makes the workflow so much smoother.

        Thanks!

        On the other hand: One can always export a finished video track plus audio and import them directly into for example Ardour or Mixbus who kan have a video track and then edit the sound from there.

        After that, one can import the finished audio track into Kdenlive and then render the finished video.

        It might be the best idea anyway.

    When clicking on clip then speed there is no option to slow down, only speed up – is there a way to slow down clips?

  22. TeeCee
    TeeCee on January 14, 2020 at 12:17 AM

    Disregard my previous, I found the answer- click on the clip in the project bin not in the timeline.

    Running Kdenlive 17.12.3 on Linux Mint 19.3 Cinnamon from your PPA: “deb http://ppa.launchpad.net/kdenlive/kdenlive-stable/ubuntu bionic main”

    Most recent update breaks Kdenlive. Launching it from terminal showed tons of blacklisted items, then something regarding (IIRC) duplicate entries for some frei0r* things, then that there is an issue with the breeze theme, that ladspa is not available and a few more.

    I used TimeShift to revert to previous version using a snapshot from 10.1.2020 and it’s working again.

    I have no idea how to address this issue so I will put those PPA updates for Kdenlive on hold for a while OR until I’ll be coming across some additional information on your site.

    Pasted text in the title clip editor is impossible to read. It puts the highlighter on it when trying to edit the text so you get white on white. Not sure if this is a bug but it would be nice to fix.

      It is a visual glitch. This bug doesn’t affect your editing though. 😉

    I go through a clip and mark each piece I want with Set Zone In/Out and then I add the zone to project bin. I give the zone a name and do this for all the bits of the clip I want. However when I then move the named zones from the bin to the timeline they do not show up with their name, they all appear with the parent clip filename. Is there a way to get them to show in the timeline with useful names (otherwise I just have a tone of zone segments all labelled the same). I tried to use the marker functionality but that means just relabeling everything I have already labelled..

      You must make it executable. Also notice that the latest version is 20.04.1
