Estimate the upload file size of a YouTube video from length and resolution.
Total bitrate in megabits per second over the run length gives megabits, then dividing by eight converts to storage units. Upload time, storage and delivery all scale with file size, so a quick estimate catches enormous files before the upload queue.
