Hi Gábor,

The slides are turned into a video segment; the terminal session recordings as well. The final step is just to concatenate them to a single video track. This can be done with ffmpeg. All of these segments would be silent. A single narration audio file is then merged as the audio track. > Have the narrator optionally overlaid onto the video > (for example in the bottom right corner), and make the narrator > screen the video when we have neither screen recording nor slides to > show. My preference is to not have a video of the narrator at all, actually. This avoids problems of embedding / overlaying video without obscuring the content, recording quality differences, etc. I think for 3 minute videos the slide content / terminal session recordings would be sufficient. -- Ricardo
