Download six different ~8 hour h.264 38.8Mbps 29.97fps 1080p clips
So, you're going to try and squash 230MB of 5760x2160 into a 7MB (what? 640x480) video ...
An eight hour long seven megabyte video would look pretty terrible.
Please at the very least learn the difference between Mbps (megabits per second: a data rate), and MB (megabytes: a storage size) before you pretend to know enough to teach me a lesson on MPEG video processing (my area of expertise for the past ten years), much less how you think a "7MB" (or 7Mbps for that matter) video must look.
I still think that if the graph is worth displaying, that it would be better overlain at the destination than the source, but you'll find that out.
With respect, I humbly suggest you consider sticking to what you know, without trying to repeatedly pass off complete BS as "better".
By all means, shoot me a PM if you'd like to learn a little more about my application. I won't be responding again publicly.
