setAudioChannelMapping for ProjectItems (premiere pro)

[maca134]

Using the sample here as reference, i been trying to setup channel mapping but it only works when parameter 2 is set to zero. not completely sure what (4,5) params are suppose to do on a stereo clip but i tried them with no result

var mapping = item.getAudioChannelMapping;
mapping .audioClipsNumber = 1;
mapping .audioChannelsType = 1;
mapping .setMappingForChannel(0,0);
mapping .setMappingForChannel(1,1);
item.setAudioChannelMapping(_mapping);

My assumption is the code above would set left -> left and right -> right channels but only the left channel gets set.

The clip is stereo and I can set the channel mapping manually.

I've sent some working example snippets to your email; were they any help?

Hello

Today I learned about programming in Premiere script with this amazing tutorials

Well, I'm not a programmer and it's not easy for me, but, I get how to create buttons and execute some functions (using parts of code from here)

Now I'm trying to make a button to change the output channel assignement of a multichannel sequence. I have a multichannel sequence (6 audio mono outs, 3 stereo) as you can see on the image.

Is there a way to map the output of channel (by name) from 1-2 to 3-4?

Normally you can do this clicking right button on the track:

For example: TRACK NAME OFF_A (mapped from 1-2 audio outs to 3-4).

I appreciate any information to help me. Thank you guys

You can control sequence channelization, with the sequence settings object.

Thankyou @bbb999 for the info. I'm going to try it. I'll send here my results after/if it works :)

Well, I've been trying all day long... and nothing :)

I think that maybe there is no way to do it. (in fact, I'm not a programmer an maybe I'm wrong). So I just edited a video to show what I would like to get with a line of code. Because I try, and try... and there's no light on my brain xD

This is what I'm trying... https://youtu.be/RKwhUtuq4yg (1 minute video)

The instruction could be something (not far from)... ...Active.Sequence.track[0].setAudioMappChannelTo->1-2 But Maybe there's no instruction to map general tracks, instead of clips inside on tracks?

Thank you :)
