Premiere blocks "adaptive noise reduction" for some 5.1-clips - What is the reason?

Hello,

I am wondering, why the effect "adaptive noise reduciton" cannot be applied to all the 5.1 audio clips. For some of the clips, it works, for others premiere says: The effect can be applied only to stereo clips. But in fact the effect works fine for some 5.1 clips which have the same file format, in the same project, captured with the same camera....

Has anybody an idea? Thanks!

Look in the clip properties for the audio for the two sections. Did PrPro import one as stereo, the other as mono or adaptive? Also, the Sequence settings audio setup ... is one built using stereo, the other mono/adaptive?

Hello Neil,

thanks for your reply! I have looked for the settings of both the audio clips (right click > settings), which seem to be exactly the same.

With the Sequence-setting I am not sure:

If I click sequence > sequence settings, the audio type is grayed out.

But if I right click on the sequence in the explorer and then "settings", the information "stereo" is shown.

So I am not sure if there went anything wron? I hope this information helps, see screenshots below:

Right-click the clips in the Project panel. Then go to Modify/Audio Channels, and see what it shows in this box:

In this clip, it shows that PrPro sees this clip from my GH3 as a stereo clip. If you click the drop-down arrow by the Clip Channel Format box, you get the following options:

There you can change how PrPro 'sees' the clip. You can change it there, but once on a timeline, I think that 'sticks' for that clip on that timeline. See if it shows the clips as different there in that dialog.

Also, for clips on the timeline, you can right-click a clip, go to "Audio Channels" and see what it shows for that sequence. Same box. But you can't change the audio channel type on the sequence use of a clip ... that's grayed out. You can only change which Media Source Channel is used for which input/output.

Ok, I just checked the settings for both clips in the project panel and in the timeline. As you correctly said: If the audio channels are changed in the project panel, the changes will be valid only for all clips which are inserted aferwards to the timeline. The clips which are already in the timeline will be not changed.

I found something interesting: In the project panel, the clip 272 (where the "adaptive noise reduction" works) is interpreted in the timeline different than in the project panel. (Although i never made never there any changes) Here is Rs=LFE and LS=C,

The 488 clip has in the project panel and the timeline the same and correct allocation. Strangely here can be "adaptive noise reduction" applied...

By the time it turned out, that to some of my 5.1 audio clips it is even not possible to apply an equalizer. This is really sad. I have no idea any more what the problem is.

Hello Richard M Knight,

thank you for your reply. The issue is at the moment already at the adobe support. But of course I can give you a sample. I created a project with ONE videoclip. The videoclip is 2 times in the timeline. One time I can apply the effect, one time not. This is really strange. The only difference is: The clip where it works, was already draged to the timeline some weeks ago.

The other was just today draged and dropped to the timeline. And I notice that also in my current project: Only the clips which had been draged to the timeline some weeks ago work fine...

Here is the project and the videoclip:
