How it works
- = ( + ) × /8 × (1+/100); ← = ×8//(1+/100)−
- Worked example: (10+0.2)×1,000,000×600/8 = 765,000,000 B = 765 MB
- Supported input limits: : 1e-12 ≤ x ≤ 1,000,000,000,000; : 0 ≤ x ≤ 1,000,000,000,000; : 0 ≤ x ≤ 1,000,000,000,000; : 0 ≤ x ≤ 1,000; : 0 ≤ x ≤ 1,000,000,000,000

Assumptions and limitations
Video and audio rates are average megabits per second, with overhead added to their combined size. Target-size mode subtracts audio before solving the video budget. Variable bitrate and container behavior may change the actual exported file size.
