What’s inside
Twelve calculators, prep through delivery.
Aspect ratios, timecode, film stock, data rates, and upload times. Each one takes the units you actually have on set or in the suite and returns the number you need, with drop frame, anamorphic, and codec presets handled.
Data to Time
Recording time from storage size and data rate, with codec presets.
64GB @ 50Mbps→ 2h 50m 40s
Film to Time
Film length to running time for every gauge, perf count, and frame rate.
1000ft 35mm 4-perf @ 24fps→ 11m 6s
Frames to Timecode
Add a frame count to a start timecode, drop frame or non-drop.
01:00:00:00 + 120 frames @ 24fps→ 01:00:05:00
Speed Percentage
Speed and duration change for a frame-rate conversion.
120fps → 24fps→ 20% speed, 500% duration
Target Bitrate
The bitrate that lands a runtime at a target file size.
4.7GB / 2h 15m 30s→ 4.63 Mbps
Target Length
The speed change that brings a clip to a target duration.
1m 30s → 1m 00s→ 150% speed
Timecode Calculator
Add, subtract, multiply, and divide timecode values frame-accurately.
01:15:30:12 + 00:45:20:08→ 02:00:50:20
Timecode to Frames
Frame count between two timecodes, drop frame or non-drop.
01:00:00:00 to 01:00:05:00 @ 24fps→ 120 frames
Time to Data
Storage needed for a recording time at a given data rate or codec.
1h @ 100Mbps→ 45 GB
Time to Film
Film length needed for a running time across formats and speeds.
10m @ 24fps, 35mm 4-perf→ 900 feet
Upload Time
Transfer time from file size and connection speed.
10GB @ 100Mbps→ 13m 20s
