Hi Kris, with that, you've touched one of the weak spots of the Cinelerra GUI. The handling of sound so that it keeps in-sync with the video. Actually, one would expect that there is some kind of "link" between the video and the accompanying sound clips. But such was never implemented for Cinelerra. Rather, there is just a "GUI trickery". You always try to do all edits (cuts, trims, rolls) with sound and video at the same time. This way, the sound is moved alongside with the image. Thats definitively some annoyance, which you just need to get accustomed to. Now, to allow this kind of handling, Cinelerra uses the concept of "armed" tracks. A track which is "armed" is enabled, and will respond to all editing operations. A track which is not armed is kindof locked. Any material sitting there will remain unaltered. And besides that, there is just the rule that any newly added material will be added to the top most armed tracks of the repective kind. I.e., when you add you new video clip, which has one video stream and just one audio stream, then the video stream will be inserted into the top most armed (enabled) video track, and the sound stream will be inserted into the top most armed audio track. And, unfortunately, in your case, the latter happened to hold the left channel of your previously inserted material with stereo sound. I am not aware of any easy solution for that problem. Personally, what I do in this situation is: - first put the second video (with the mono sound) on separate tracks as a whole. - create a second sound track and copy the sound identically on that, i.e. make that video also into a video with two sound channels - then select the interesting part of that new setup and save it as a new clip (make sure, the correct configuration of tracks is "armed" for that purpose) - and then I load that new clip into the viewer and mark and insert the interesting parts into the timeline I know, that's ugly and tedious. Maybe someone knows a better solution?
