This would save many hours of time once applied to hundreds or even thousands of videos.
Muxing the xml.gz and the thumbnails together takes only a second or two. Even though that would still be a total of two lines, the big video file is only being decoded one time for all of my conversion and qctools work. I think the first and second commands could also be combined into one line by splitting the video another time and piping that directly into ffprobe. However, in reality, I would add other, non-qctools related outputs. In this instance, I'm not doing any other conversion with ffmpeg.
