The VideoLAN Forums

I have a playlist of music videos and there's 2 videos that are much quieter than the rest

I've tried doing the Volume Normalising method where I:
- go to preferences, then show all, then audio, then filters
- go to Volume Normalizer
- set "Number of audio buffers" to 10 and "Maximal volume level" to 1.6
- quit VLC, reopened, and I have the same problem where the 2 videos are much quieter than the rest

I've also tried doing the Dynamic Range Compression method (https://www.lifehacker.com.au/2012/06/how-to-fix-movies-that-are-really-quiet-then-really-loud/) where I:
- go to preferences, then show all, then audio, then compressor
- raise Makeup Gain with the quiet video (volume on the video doesn't change and when I max the makeup gain and restart VLC, I don't notice a difference in the volume)
- change ratio slider, threshold and the rest of the steps but still didn't notice any changes

Are there any other ways to fix this problem?

I fixed it

I had to tick the "Volume Normaliser" or "Dynamic Range Compression" box in the Filter tab to enable those changes.

Volume normaliser sort of fixed my problem, but killed the dynamic range so things didn't sound right

DRC worked, but I just need to do some tuning
