Duration, starting at zero. Hours continue past 24.
One shared frame rate
Both inputs use the selected rate. Changing it reinterprets the frame fields; it does not convert footage between frame rates.
Count durations, not endpoints
Subtracting A − B gives elapsed frames. It does not include both endpoints. Negative results are rejected. Frame fields must be smaller than the frame rate.
Keep the exact count
Use colons and two digits per field, with extra hour digits if needed. No semicolons, decimal seconds or signed values. Maximum: 9,007,199,254,740,991 frames.
