w × h × fps × motion × 0.07 ÷ 1,000,000 = Mbps
VBR target = CBR × 0.75 · VBR max = CBR × 1.5
Based on Kush Amerasinghe's H.264 for the Rest of Us (Adobe Systems),
adapted for both traditional video and motion graphics content.
While these calculations were originally developed for traditional video,
they work equally well for motion graphics content when considering
the overall complexity and speed of movement in your animations.
