Mono is one track of audio stream ONLY so there is nothing to fill.
When you use the Fill L/R Effect... it does not create a stereo effect from a mono track.
It is designed to fill the left or right of a STEREO track with the respective audio as chosen.
eg. Record into camera with 2 different levels of audio ( hi / low) and choose the best in the edit
Essentially..the same audio is used on both stereo tracks. ie result = same level, same quality, but no stereo effect. Its just a Stereo track as 2 equal audio streams.
Shooternz's explantion is spot on.
Changing your mono clip to stereo will have no acoustic effect.
But if you need to do it for some reason; to coexist with other stereo clips or whatever your reason; there is an easy way to convert your mono clip to stereo. Its called source ch mapping:
- Select your mono clip in the project panel
- menu: clip/audio options/source channel mapping
- Choose Stereo and click OK.
Now Pr will treat that clip as a stereo clip.
So how do you fix it?
How do you fix what?
The problem is the video is in the project panel and there isn't any unlinked audio files in the project panel. How do you get those audio files in the project panel so I can do the above mentioned work around?
Follow the same procedure. You can source ch mapp audio that is linked to video also.
BTW: This isnt a work around to anything. You were using "Fill right" filter incorrectly. It is meant to fill an empty right ch in a stereo clip with the conents of the left ch.
If you want both channels filled with the same thing; choose "Mono as Stereo" rather than "Stereo". Choosing "Stereo" assumes you want to map the mono to one ch and fill the oher with whatever you want. "Mono as Stereo" maps the same mono ch to left and right stereo chs.
Another way to achieve the mono as stereo is to just duplicate your mono source Clip on the Timeline. Then, in Window>Audio Mixer, you can alter the Balance of those two Tracks to suit. The Mono as Stereo is quicker.
I think everyone is assuming that you have a clip that is video plus a mono audio track. Is that correct? If so, you select that clip and do what Curt suggested with the audio.
If not, what do you have?
If you are trying to get the output to be stereo, and you don't really need to clip to have a stereo track, create the sequence with a stereo master, and just leave the clips as mono. The output will be stereo with the same thing in both channels.
Here's my guess.
You have a stereo track, not mono. You have audio only on the left channel. The right channel is blank. You used the Fill Right effect trying to get the left channel audio to come out both speakers. But the Fill Right effect actually places the right channel audio (blank) onto both tracks, making the whole thing go dead.
If I'm right, use the Fill Left effect instead.
