I'm trying to render some videos I've edited with Kdenlive. But during the render process it keeps crashing. Here's an excerpt:

The above error is from Kdenlive version 19.04.1 but I have also tried rendering from nightly snapshots from as recently as yesterday and get the same or similar errors.

I *have* been able to render at least one video, but yet I have several others that crash. I don't know what's different about them.

The settings for the render job are:
- Generic (HD for web mobile devices) -> MP4 - the dominating format (H264)
- I am setting the quality as high as possible. And I'm setting the encoder speed to the middle. Threads are set to 6.

I've tried fiddling with the settings using slower encoder speeds and less threads. I also confirmed that "Use GPU processing (Movit library" is unchecked. (since a saw a suggestion to do that one of the google searches I saw).

Please help. I have about 7 projects I want to render and I'm stuck with this continuing to crash. I'm on Ubuntu 19.02 (if that matters).

I saw the errors regarding

No LADSPA plugins were found! Check your LADSPA_PATH environment variable.

Googling that revealed that I needed to install two packages (ladspa-sdk and swh-plugins) - which I did. That got rid of the error, but the render still crashes. Here's a revised log:

19.04.2e solved some mlt rendering issues.

Please try with the current Kdenlive AppImage version 19.04.3b to see if there are any packaging issues https://files.kde.org/kdenlive/release/

If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.

Really starting to regret using Kdenlive to handle my video editing. I love that its free but the constant crashing makes it barely usable and I've tried so many different versions up to and including nightlys. If anyone else has any ideas or suggestions, please let me know. I'm a little uncertain what to do other than switch to Adobe Premiere or something similar.

Sorry to not look closer to the error message. It seems you have clips with 59fps and 29fps in your timeline which are not standard frame rates. This should be either 60fps or 29.97/30fps. Check these clips with the original clips you have or use a muxer to change it to 60fps or 29.97/30fps.

The videos were shot with a go pro camera. I'm a complete amateur when it comes to video editing. What's a muxer and how do I use it to fix this issue?

I did speed a number of my videos up to play 1.5x or faster. Is that what's causing this? Or is the problem with the original videos?

I can't remember if i took the video in 4K or 1080p? Maybe that's the issue? Do I need to change my project type?

Sorry I'm a bit lost.

I am just doing some reading it and seems as though MLT the media framework kdenlive uses should adjust the framerates of the source files to the project framerates. If that's the case are the above messages errors or simply warnings that its changing the framerate?

I think its the later although again I'm a total newbie when it comes to video editing. Is there some other way of seeing why kdenlive is crashing? This is so frustrating I spent hours selecting clips and arranging and adding transitions and now it seems like I can't render the resulting projects.

Changing the project settings after you put clips on the timeline you'll get strange results and errors (and as I remember correct not only in Kdenlive but in all other editing software as well).

Could you make a test? Take one of your clips and put it into a new empty project. Kdenlive ask you if it should change the project settings. If so click yes. Then the project settings get adapted to the clip you use. Take 1 or 2 other clips and put it all on the timeline. Render with Mp4. Now it should work. If so let me know the size and frame rate like: 1080p 30fps. If it renders without an error you have a problem because you have to redo the whole project again.

I have changed the project settings in an attempt to solve the rendering issue but never saved them... so I don't think that is the issue.

I also attempted to remove transitions and that didn't help either. There are other effects involved though like fade to/from black, audio gain, transform and etc.

Some videos I have *WILL* render so its not with every single video.

I can try to setup a new project but if I have to go through all that effort I'd rather do it in another program like adobe premiere or blender as I just don't have the most faith in kdenlive at this point. And I don't want to sink all that effort and have something unrenderable again.

I never dreamed that rendering would be such a problem. I'm using video taken with a go pro which I think is a pretty common place amateur camera.

Hi,
I had the same problem of crashing while rendering, and I tried a little solution to fix it
It's just by rescaling images before editing the video
So if you're working on a HD video resolution and you insert a 4K image it will be acceptable at editing but will crash at the rendering
So you need just to scale down the images before inserting them on your project
May this be helpful for everyone
