Calculate video bitrate from resolution, frame rate, and quality target. Estimate file size and streaming bandwidth for H.264, H.265, and ProRes workflows.
Calculate video aspect ratio dimensions from width or height. Convert 16:9, 4:3, 2.35:1 cinema, and vertical 9:16 for social media and broadcast formats.
Calculate total pixels, megapixels, and file dimensions for video resolutions. Compare 720p, 1080p, 4K, 6K, and 8K production formats.
Total frames remain constant unless interpolating or dropping frames during conversion.
Frames = Duration (sec) × Source FPSSame frames at higher fps = shorter duration (speed up). Lower fps = longer (slow down) if frame count preserved.
New Duration = Frame Count ÷ Target FPS24fps → 30fps playback at same frame count = 125% speed (faster by 25%).
Speed % = (Target FPS ÷ Source FPS) × 100Updated: July 2026
10 sec @ 24fps = 240 frames. At 30fps = 8 sec duration if played at native frame count — or use 3:2 pulldown for broadcast.
5 sec 60fps = 300 frames. Conform to 24fps = 12.5 sec — 250% slow motion retaining all frames.
2 sec real-time at 120fps → 10 sec at 24fps (5× slow) using every frame.
Calculate duration and frame count changes when conforming video between frame rates. Enter source fps, target fps, and clip duration to get new duration, frame count, and speed change percentage for editing and broadcast delivery.
