Maybe we’re thinking two different things. I thought you wanted to remove the media from the clips. It sounds that you want to separate picture from sound on the source clips? Depending on what your eventual goal is, here are two ways to do it:
1. This is the subclip process. Load clip in source monitor, turn off the tracks you do not want to keep, mark IN-OUT on the range you want to have (or entire clip) and you can drag the clip icon above the monitor into a bin. Or you can option-click or alt-click (Wndows) the image itself in the source monitor and drag to a bin. There’s also a dedicated subclip button from the tool palette you can map if you plan on doing a lot of this.
2. If you are doing this to prepare syncing of double system sound and want to remove audio from the existing clips. then you can just do this as part of the sync process. In the AutoSync dialog box there is an option to keep audio on source video clip, just don’t check that and the resulting clips will have scratch audio removed and doiuble system audio attached. You can also define which range of the BWF tracks you want to keep such as MIX track only. For example, if MIX was on A1, you would select the range to be A1-A1 and that would be the only track used.
