Adding an audio fx at the media level

[Matt Carlson]

There is not a media level effects chain for audio. It is possible to affect an audio clip scattered in edits throughout a project though. It is not pretty but it works. Create a new audio track and place the complete audio clip there (or use Soundforge or another external editor as another possibility.) Right click and apply a non-real time event FX. This will bring up the render templates and continue to render out a new clip. Since it is audio it takes very little time. A new clip (usually named with a “Take 2” after) now exists. Go back to the media bin and right click your original media. Choose replace and then pick your newly rendered clip. All the non linear edited events in the timeline remain intact replaced by the new “Take 2” clip. You can reverse the process by choosing replace again and going back to the original one.

Thanks Matt,

As you say, not pretty but… it sounds promising. I need a bit of clarification though.

1. my audio comes from a .MTS video file how to I replace it?
2. how do I tweak my audio clip so it’s not done “real-time”? I think I only know how to add effects that are real time.

Cheers,

Gilles

First the implementation of non real time events. They are in basic terms the clip level audio you are seeking except they always have to be rendered.

If you choose ANY audio event including one grouped to video about a third of the way down on the right click menu you will see the Audio Event FX option that is the redundancy of clicking the event chain button at the end of the event. Directly below that in the menu is the option for non real time events that you want. Upon clicking that you can build the audio event chain and when you hit OK the render will portion come up to make the alternate take. When you do this the alternate take will immediately replace the original audio event (not the entire media original.) If you right click the event again this time go to Take on the menu (below Switches.) You can choose between the multiple possibilities (in this case we would now have just 2) by selecting Choose Active.

By creating a scratch track of the original media you can render out a new audio file that you can then use as the replacement option in the media bin. Unfortunately here is where my usual workflow conflicts with the problem you have. I normally split the audio from the video before I begin editing. In your case replacing the original clip with a new rendered audio take will turn the original video in to a black audio only clip. I will look to find ways to quickly replace the original audio of a video with the new rendered take. It seems like it should be possible. The replacement scenario will work if you choose to render the original video and effect audio out as a whole. How long is the original clip? I sense that this will be more time wasteful than the other option of finding all the events by hand and adding audio effects.
