Calculate video bitrate from resolution, frame rate, and quality target. Estimate file size and streaming bandwidth for H.264, H.265, and ProRes workflows.
Estimate video storage needs from bitrate, duration, and clip count. Plan SSD, NAS, and cloud storage for editing archives and raw footage libraries.
Convert frame rate timing for video speed change and pulldown. Calculate duration change from 24fps to 30fps, 60fps to 24fps, and conform footage math.
Realtime factor 0.5 = twice realtime (10 min clip → 20 min render). Factor 2.0 = half duration render.
Render Time = Source Duration ÷ Realtime FactorColor grades, noise reduction, and motion graphics increase render time nonlinearly.
Adjusted Time = Base Time × FX Multiplier (1.2–3× for heavy grades/effects)Multiple exports queue sequentially unless NLE supports parallel project renders.
Batch Time = Σ Individual Render Times (sequential); ÷ cores if parallel segmentsUpdated: July 2026
10 ÷ 0.3 = 33 min render on mid-range laptop with hardware encoding.
5 min timeline at 0.1× = 50 min export. Heavy 4K grade may drop to 0.05× (100 min).
6 × 45 min = 270 min (4.5 hr). Start before sleep with adequate disk space and power settings.
Estimate how long video export or render will take based on footage duration, resolution, codec, and hardware render speed factor. Enter timeline length and observed realtime factor to plan overnight renders and deadline delivery.
