i noticed that if you apply a 2 pass normalization to a series of clip (analyze and continue editing), than you move the clips forward or backword, you loose the "amplification effect".

But this is only in the session you are working. If you save and reopen the project, amplification reworks perfect.

So 2 pass analyzated data is there, but the "playback engine" do not point to the correct one when you apply the move.

PS: also the effect button, remains in "analyze" instead of "reset".

i can't use the effect "at all" on Windows...

Well, the funny thing is that even though it throws an error the normalization is applied. I tried it on Windows and Linux with the 20.12.3 version.

Unfortunately "Normalise (Two Pass)" does not work for me on (Manjaro Linux). Analysis always brings: "Abort processing". This filter must be applied to a clip, and not to the timeline. Even if applied correctly there is a big bug.
This is a pity, because it is a very important effect that could set the right volume.

The same filter is called "Normalize: Two Pass" in the sister project Shotcut - and there it works wonderfully. Wouldn't it be possible for Kdenlive to see how it is done there?

Der gleiche Filter heißt bei dem Schwester-Projekt Shotcut "Normalize: Two Pass" - und dort funktioniert er wunderbar. Wäre es nicht möglich, dass Kdenlive dort schaut, wie dieser bei denen gemacht ist?

To bad it doesn't work. Didn't look if it works here.

Can't u use another plugin for that? I have ceveral normalization plugins active in my kdenlive to choose between.

And for start i import HQ audio edited before in audio-software.
As audio-software (DAW? Audacity?) is easier to work on audio, if it would become to complicated or i need high quality (sound and/or edits) eventually would export the kdenlive audio tracks to import and edit these in the audio-software.
And if the audio becomes more important, needs much more edits, and has to become high quality, then the video then i complete the video in kdenlive, and import it into my DAW to create the HQ audio under it.

Perhaps a reasonable workflow to find for you among these?
At the end, i personally am never confronted with limitations within Kdenlive (not saying there aren't), and until now could always create what i wanted. I'm happy with it. But one can't forget it is not a full DAW.

Of course, an Ardour can do much more, even Audacity is better for sound.

But, please, note that if you can do simple corrections for speech, e.g. with Kdenlive, then that is a huge advantage.
And since these filters / effects exist, I assume that Kdenlive is convinced that they belong.
I'm not expecting any exotic functions, after all.
This is about a normalizer. This allows you to set the average loudness to the LUFS norm, say -15dB. Manually this is practically impossible.
And - my question is: If Kdenlive is based on MLT, just like Shotcut, which is also opensource, couldn't you just look into the source code and see how they solved that? Besides, its leader Dan Dennedy is very open and open-minded. He already helped a lot with Kdenlive several years ago.

Each his favorit workflow. I just gave some options to think about and choose (or not).

And i agree it would be nice they would work. That regular music editing must be possible. But IMO that is. But until they work proper one can use also good alternatives.
External plugins aren't that exotic and not that hard to install.

I found this part you suggested was a good thought.

Yes, it would be very nice if....
But how can a beginner like me reach the makers of Kdenlive?

Strictly speaking, there are only two major and unnecessary bugs that need to be fixed:
Lift/gamma/gain in video and
Normalize (2 pass) in audio.
Check with Shotcut to see how they do it.
And then there are only two more wishes:
Please build such an audio "Compressor" and "Equalizer: Parametric" as they both work very well at Shotcut also at Kdenlive.

Then I don't want to complain anymore. Then I can only focus on what works much better with Kdenlive than with all other opensource video editors. That is especially the timeline!

And then Kdenlive is and remains the No. 1!!!

the best thing of Kdenlive is that is very intuitive (or maybe i'm the only one thinking that )

Hello bartoloni,
Intuitive or not, I like using Kdenlive very much, even if I stumble every now and then.
Please tell me, what do you use to correct the colors?

mickae wrote:Please tell me, what do you use to correct the colors?

Look under Effects -> Colors or Effects -> Color correction. There are ceveral options. Which option/effect depends on what you want to do with the colors.
Just try and see what it does (and discover that more roads lead to rome).

Simply by this website which contains this forum.
Go to https://kdenlive.org and look in the menu under Contribute.
There you can find out which bugs are known. And you yourself can report a (unknown) bug if you want.

Or you could go to https://github.com/KDE/kdenlive but that's not the best place for beginners.

And i guess that the first and oldest users of this forum with the names muesli, Francis Belanger, Nicolas Blanco, dan, Doug H, are closely involved.

Hello zolder,
Yes, I have been doing exactly what you say here for a few days: I am trying out the colour and image correction effects.
In the process, I have now come across SOP/Sat. This filter obviously does (almost) the same as Lift/gamma/gain. And if I then observe RGB Parade, I can also use it to adjust the white balance, the contrast and also the saturation at the same time. That is wonderful. Nobody said it would be easy if you wanted more.

More roads lead to Rome.
And if you find some way which does it for you, then you'll discover that 'that one video shoot' just needs something slightly different to fit within the rest.
Video editing is a learning curve and you'll get better by the time, by doing it (with lot's of trying). With audio i say use your ears. And with video i say use your eyes. Don't depend on 'regular/usual/common ways'. Find and do what's needed.

I am fairly familiar with it and have my favorites, and I'm still trying different options to see what looks the best for my goal at that moment.
Your never finished learning.

To keep the topic of this entry from going somewhere else entirely, I've opened a new discussion for SOP/Sat. Please have a look at it to see if it is intended correctly. Correct me, because I do not want to spread errors.
