kdenlive crashes on export

Everytime I press "Render -> Start Rendering" kdenlive crashes without any error message. Anyone experienced the same issue?

It does not happen with some newly setup projects, but with a big one I've been working on for a while

Ubuntu 16.04

I could fix it by using the latest version of Kdenlive. The latest version in the Appstore was 15, but Kdenlive 18 is provided with a .Appimage at https://kdenlive.org/en/download/ .

With the new version the crash did not happen yet.

Thanks for all participants, though.

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
