Twelve Essential Calculators

A comprehensive suite of professional calculation tools for filmmakers, editors, and cinematographers. From aspect ratio conversions to film stock calculations, all designed with precision and Apple's signature attention to detail.

Aspect Ratio Calculator

Convert between different aspect ratios and resolutions, handle anamorphic footage desqueezing and scaling with precision.

Example:
1920×1080 to 2.35:1
1920×817

Data to Time Calculator

Calculate recording time duration from storage size and data rate with codec preset support.

Example:
64GB @ 50Mbps
2h 50m 40s

Film to Time Calculator

Convert film length to recording time based on format and frame rate for all film formats.

Example:
1000ft 35mm 4-perf @ 24fps
11m 6s

Frames to Timecode Calculator

Convert frame count to timecode starting from a given timecode with drop frame support.

Example:
01:00:00:00 + 120 frames @ 24fps
01:00:05:00

Speed Percentage Calculator

Calculate speed percentages for frame rate changes and their effects on playback duration.

Example:
120fps → 24fps
20% speed, 500% duration

Target Bitrate Calculator

Calculate required bitrate for a target file size and runtime with precision accuracy.

Example:
4.7GB / 2h 15m 30s
4.63 Mbps

Target Length Calculator

Calculate speed/duration changes needed to achieve target clip length for editing workflows.

Example:
1m 30s → 1m 00s
150% speed

Timecode Calculator

Perform arithmetic operations (add, subtract, multiply, divide) on timecode values with frame accuracy.

Example:
01:15:30:12 + 00:45:20:08
02:00:50:20

Timecode to Frames Calculator

Convert timecode difference to frame count with drop frame and non-drop frame support.

Example:
01:00:00:00 to 01:00:05:00 @ 24fps
120 frames

Time to Data Calculator

Convert recording time to required storage size based on data rate and codec settings.

Example:
1h @ 100Mbps
45 GB

Time to Film Calculator

Calculate required film length for desired recording time across all film formats and speeds.

Example:
10m @ 24fps, 35mm 4-perf
900 feet

Upload Time Calculator

Estimate upload duration based on file size and internet connection speed with network variability.

Example:
10GB @ 100Mbps
13m 20s
