I've been using kdenlive every day for 2,3 months after leaving programs like adobe premiere. Unfortunately, there are certain problems. The preview render also doesn't work correctly, either it comes late, crackles or explodes. Especially when I add an effect, these become even more. In the project I'm working on right now, the sound is ok in preview, but when I export, the sound is distorted, sometimes there is, sometimes not. I don't understand what I did wrong. This problem occurs when I add effects to the sounds. I will be glad if we can find a solution because what I did without the sound effects I added is meaningless.
