I’m slowly learning how to use my video production tools.
Yesterday I discovered the 2 pass audio normalization feature in kdenlive.
You seem to need to apply this effect to each clip separately.
This 2 pass effect is much easier to configure than the other normalization option, which requires more configuration settings.
With the 2 pass audio normalization you just nominate your desired volume, click Analyze, and you’re done. You need to do that for each clip.
Now that I know how to do this the audio on my videos shouldn’t be as terrible as it has been. Getting better. Slowly.
