  • Copying Audio from one channel to another

    Have a video clip that due to a microphone connection problem has audio only on the left channel (in a certain section). How can I duplicate the audio of the clip so that it plays both L&R channels. Have duplicated the audio and selected Monaural 1, 2 etc on the second track, but the copy always plays on the left channel, and also shows in the waveform as the left channel. Any ideas? Thanks.

    click the little a on left of the lower audio track and then click clear all tracks, then the monoraul 1 and 2 will work

    also, there is no need to duplicate the track, simply slice the clip where the problem starts and again where the problem ends, then set the problem section to monaural1 or 2, depending on which track has the sound

    or apply the panpot filter and set pan to midlle position

      Thanks Anton. Had already sliced the problem part of the clip. Your suggestion of applying a pan pot filter was the easiest fix, and worked a treat. Thanks again.

        You could right click on the clip, select properties and from the audio tab choose mono channel 1 or mono channel 2 which is my preferred way.

              Either way.

              One additional benefit is that once you get the setting you like in the Panpot filter, you can then save it as a user preset and apply it to several clips at once if needed.

                yes, I often apply it to a couple of hundred clips in one hit

                  I would love the option of selecting multiple clips and apply the same thing in properties to all at once. If I have a lot to do I use the pan pot filter as you suggest.

                  I prefer the properties way because the waveform on the timeline reflects the results.

                  I also use pan pot to hugely increase the volume on a clip. You can only do so much with the rubber band on the timeline but I can put loads of pan pot filters on a clip, each one increasing the volume by several DBs, and boost very low lever sound effectively.

                    No left channel audio

                    I have similar problem with audio channels. Ther used to be a "swap channels" effect in Adobe, that did the job, but the "Panpot & Balance" can only mute a channel, which is already mute. It's meaningless.
                    I have also tried the channel map thing, It doesn't change anything at all. Only mutes the channel which is playing.
                    When I change the setting to monaural, it also mutes everything.

                    Am I missing something?

                      That is not how it works. The panpot filter also let you choose which channel goes out either over 1 channel or both. (if a clip has 2 channels )

                      The best way to manage tracks is with mapping IMHO.

                        be sure to do the mapping in sequence settings and not in project settings

                        in the attached example, the left channel of the clip will be output on both speakers and the right channel will be muted, the possibilities are endless

                          The "panorama and balance" works well in a stereo track. When you open the dialogue box, ignore the balance handle at the bottom! Have a look at the very top instead. There you have two horizontal handles. As default, for the left channel the handle is on the left side, for the right channel it is on the right.

                          If you want to swap channels, just turn the left handle to the right side and the right one to the left. Done.

                            Thank you Anton, I didn't see that the mapping audio was tunable in the sequence properties. IMHO it's the best solution to start, determine wich track is receiving the mono records... and mapping it. Until now I was only using PanPot and balance... that brings the volume also...

                              Everyone should learn how audio mapping works.
                              Also to change channels on clips that are already on the timeline, you can right click, select properties, look on the bottom under channels and select whatever channel you desire.

                              Because we work off of the source clip, we can change channels on any clip at any time.
