One pass normalize filter between mlt files

[Hub50]

I created a project with different mlt files on a track.

As we can see, the sound level is equivalent between the 2 mlt files on the track V2.
I applied the one pass normalize filter on the track with the default options and exported the project.
I imported the result on the track V1.
There is a high gap at the limit of the 2 clips and the sound level increases very quickly and is very disturbing when I listen the result.
It seems that the window size of the filter is not continuous between the 2 clips (which are mlt files).
What should I do to have a stabilized sound level at the transition of the 2 clips in the final video ?

There is a discussion here which is relevant:

How does normalizing work across clips?

Yeah. I see what you mean. When you put the filter on a track, it watches for discontinuities (like the start of a new clip) and it resets the averaging window. A workaround is to add the filter to the Output of the timeline instead of of the track: [image] The side effect of this is that it applies normalization to the entire project, not just the one track.

The next release will include an option to disable the discontinuity detection.

Some options in the mean-time:

• Put the filter on the output instead of a track
• Apply a gain filter on each clip so that their average sound is closer
• Add a compressor filter in addition to the normalize filter to smooth out transitions
