Question about working with multi-stream videos

Using Skype + Call Recorder produces a odd recording.

Two audio channels. One mono of the local end. One stereo of the remote end.

Two video channels. One separate video for each end of the conversation.

When imported kdenlive seems to only show the local recording (video + mono audio) in the timeline. So the remote end of the conversation can never be manipulated.

First question, let me know how to click + move/position one video so it's to the side of the other video stream, similar to how ScreenFlow or Camtasia do this.

Second question, let me know how to process each audio track separately.

If there's no way to do this inside kdenlive, I can separate all the elements with ffmpeg and import them individually...

And if there's currently no way to do this, best to treat this as an enhancement request.

This becomes complex in conference recordings with one video + audio per participant.

Best for kdenlive to introspect into the file container and present each stream separately on the timeline. For audio tracks best to be able to also separate left + right channels and mute/volume-adjust each separately for fast normalizing.

Click http://InsideTrackParty.com/test/ for a 30 second test clip.

There's the original Skype video and another smaller video with the audio stripped.

Also the ffmpeg syntax used for the strip operation is in the audio_remove.txt file.

Thanks!

In Clip Properties / Advanced, you can set the audio and video stream index. Keep in mind that index starts at 0 and that audio and video are not indexed separately. For example, video might be 0 and audio 1. Use ffprobe on the file to see all the streams and their index numbers.
