    How to fade audio and continue audio level into later clips

    jmklein Community Member

      I have the PE 10 trial.  When I add keyframes manually to fade out audio, or just select the "fade out" option to fade audio at the end of a clip, the audio adjustment ends at end of the clip and the audio of the next clips is at original level.  That creates a big discontinuity in sound level.

       

      What if I want the following clip or clips to continue at the same faded audio level, instead of starting off at their original level.

       

      In Pinnacle Studio for example, when you fade down audio, all the audio to the right will be adjusted to match the level after the fade, as long as there are no keyframes forward of that final fade keyframe.  Now that I am trying PE 10, I miss this behavior.

       

      In PE10, is there a key sequence that will allow this behavior?

          If I understand your needs, I would look into using the Audio Mixer, and applying Audio Track Keyframes for Volume. This ARTICLE mentions that method, along with several Clip-specific adjustments.

           

          Note: Track Volume Keyframes, are Track-specific, so if you change Clips, those Track Keyframes remain, and will affect any Clip that you later add to it.

           

          Good luck,

            Bill,

             

            I am confused by your last statement in your Note.  Could you clarify a bit.  Keyframes are track specific, yet I got that.  What do you mean if I change clips...

             

            It seems there is not way to adjust the volume across multiple clips, or from one point in time and forward (even if it spans mutliple clips).  It that correct?

             

            Thank you for your time and expertise.

              When it comes to Keyframing Effects in Audio, such as Volume, there are two types: Clip-specific Keyframes, that are attached to the Clip, and then Track Keyframes, that are attached to the Audio Track, regardless of what you might do, regarding the Clips on that Track.

               

              With Clip Volume Keyframes, if you Delete the Clip, those Keyframes disappear. With Track Volume Keyframes, if you swap out a Clip, or Clips, those Track Volume Keyframes will remain. That has tripped up other editors in the past.

               

              Good luck,

                OK, I was confusing track and clip levels.

                 

                Bill, I can't figure out how to specify or select track keyframes vs clip keyframes.  The audio I want to adjust is the audio track attached to the video track.  I have several video clips (audio and video) concatenated on the timeline.  On one of the clips in the middle of the timeline, I want to bring the volume down a bit, then have the rest of the clips have that same lowered audio level.  Can I do this without having to adjust the volume of every clip after the point I lowered the volume?

                 

                Please excuse my ignorance of using PE10.

                  If you only have one Clip, or just a few Clips, where you wish to attenuate the Volume, I would do that at the Clip level, and just adjust the Fixed Effect (automatically appears on all Clips with Audio), and add Keyframes to adjust the Volume.

                   

                  I find it easier to do from the Effects Control Panel, accessed by Selecting the Clip to be adjusted, then from the Effects Tab, choose Edit Effects.

                   

                  Lets say that you have a Clip, where the majority of the Volume is just right, but there is one section, where you wish to lower the Volume. Go to where you want the Volume to begin to get lower, and add a Keyframe (toggle Keyframes ON), then go to where you want the Volume returned to the main setting, and add another Keyframe. At this point, nothing has changed, but you have added two Keyframes, that will "hold" the Volume, to the existing level. Now, go to where you want the Volume to be its lowest, to the right of that first Keyframe that we added. Add another one. Adjust the level at that Keyframe (now the second in the Clip) to what you want. Go to where you want the Volume to begin rising, just before the second Keyframe that you added (now the third one), and add another Keyframe. Adjust it to match the Volume that you adjusted in what is now the second Keyframe. You will have four Keyframes: the first one, that holds the Volume in the beginning of the Clip, the second, that adjusts the Volume to its lowest setting, the third, that matches the Volume of the second, and then the fourth, that holds the Volume back to the original level for the remainder of the Clip. It will look like this:

                  Some like to do the Keyframing with the "rubberbands" in the Clip itself, but I like the Effects Control Panel.

                   

                  Also, the Keyframes that we added, are Linear, and if you want to adjust the Interpolation, to make the changes smoother, just Rt-Click on each Keyframe, to adjust the Interpolation. Interpolation is a bit abstract, so I would suggest reading the Help Files on Bezier Curves on Keyframes.

                   

                  Good luck,

                    Bill, I have no problem performing what you describe, bring volume down then back up to default level within a clip.

                     

                    But is there any way to adjust levels of multiple clips at the same time?  Like what if I wanted to reduce the volume of the entire audio track of the video file.  I don't want to have to do that on every clip.  There could be hundreds of clips.  Can I select all the audio clips, then reduce their volume some how.

                     

                    Most of the audio for my video track is muted, and only on specific clips do I raise the audio for a few seconds then bring it back down to muted.  So if I have 100 clips on my timeline, how can I do that without having to edit every clip?  I have a soundtrack that is playing most of the time, and only occasionally do I want to hear the original audio.

                      The way to adjust the Volume for multiple Clips can be done one of two ways.

                       

                      The first would be to make the adjustments to the first Audio Clip (do not do the Keyframing for Volume attenuation at this step, to allow for the dialog to come forward), then Rt-click on it, and choose Copy. Next, Select all other Audio Clips, Rt-click, then choose Paste Attributes. Done. Then, go back and use the Keyframing, as described above, to selectively attenuate the Volume, as needed.

                       

                      The other is to do the attenuation at the Audio Track level, with the Audio Mixer. Just play the Timeline, and adjust the slider in the Audio Mixer, for the appropriate Audio Track, to apply Track Keyframes to it. See that linked article for more detail, and caveats.

                       

                      Did you move the Audio Clips from the Soundtrack Audio Track? Did that help?

                       

                      Good luck,
