Video Timestamp Calculator
Add or subtract video timestamps, or find the gap between two, and see the frame number and HH:MM:SS:FF timecode at 24, 25, 30 or 60 fps.

| Tool | What it answers |
|---|---|
| Audio Bit Rate Calculator | Uncompressed audio bit rate is sample rate × bit depth × channels. |
| Audio Duration Calculator | Audio duration equals the file size in bits divided by the bitrate in bits per second. |
| Audio File Size Calculator | Audio file size equals bitrate times duration divided by 8. |
| Video Aspect Ratio Calculator | Divide the width and height by their greatest common divisor to get the aspect ratio, then scale the other side by the same proportion. |
| Video Bitrate Calculator | Video bitrate is the file size in kilobits divided by the running time (counted as seconds), minus the audio bitrate. |
| Video Duration Calculator | Video duration equals the file size in bits divided by the total bitrate, or the frame count divided by the frame rate. |
| Video File Size Calculator | A video's file size is its combined bitrate multiplied by its duration, divided by 8 to turn bits into bytes. |
| Video Frame Rate Calculator | Playback speed equals the timeline frame rate divided by the capture frame rate. |
| Video Timecode Calculator | To add or subtract timecodes, convert each to frames, do the arithmetic, then convert back. |
| Video Timestamp Calculator | To add video timestamps, convert each to seconds, combine them, then convert back. |

Audio Bit Rate Calculator
Work out uncompressed PCM audio bit rate from sample rate, bit depth and channel count, plus WAV file size for any duration. CD audio is 1,411.2 kbit/s.
Audio File Size Calculator
Estimate audio file size from bitrate and duration, or from sample rate, bit depth and channels for WAV. One minute of CD audio is 10.58 MB.
Audio Duration Calculator
Work out how long an audio file plays from its size and bitrate, or from WAV sample rate, bit depth and channels. 4.8 MB at 128 kbps is 5:00.
Video Timecode Calculator
Add or subtract two HH:MM:SS:FF timecodes at 24, 25, 30, 48, 50 or 60 fps and see the result as timecode, total frames and seconds.
Video Bitrate Calculator
Work out the video bitrate that fits a clip into a set file size: enter size in MB, GB, MiB or GiB, the running time and audio kbps.
Video File Size Calculator
Estimate a video's file size from its video and audio bitrates and running time. Shows MB, GB and GiB, e.g. 8 Mbps for one minute is 60 MB.
Video Duration Calculator
Find a video's running time from its file size and bitrate, or from frame count and frame rate. A 1 GB file at 8 Mbps runs 16 min 40 s.
Video Frame Rate Calculator
Work out playback speed, slowdown factor, frame count and timeline length when footage shot at one frame rate is conformed to another, e.g. 120 to 24 fps.
Video Aspect Ratio Calculator
Reduce any video resolution to its aspect ratio and find the matching width or height for a resize, e.g. 1920×1080 is 16:9 and 1280 wide needs 720 tall.
