The rob’s timecode calculator is an essential tool for filmmakers, editors, and sound designers. It quickly converts standard SMPTE Timecode (HH:MM:SS:FF) into Total Frames or reverses the process, providing accurate time data based on your project’s Frame Rate (FPS).

rob’s timecode calculator Formula:
TotalFrames = (((H * 3600) + (M * 60) + S) * FPS) + F
Total Frames to Timecode:
TotalSeconds = Math.floor(TotalFrames / FPS);
H = Math.floor(TotalSeconds / 3600);
M = Math.floor((TotalSeconds % 3600) / 60);
S = TotalSeconds % 60;
F = TotalFrames % FPS;
Variables:
- Frame Rate (FPS): The number of still images displayed per second, crucial for determining the total number of frames in a given time period. Standard values include 23.976, 25, 29.97, and 30.
- Timecode (HH:MM:SS:FF): The standard format for labeling video and audio frames, representing Hours, Minutes, Seconds, and Frames.
- Total Frames: The sequential, continuous count of every frame from the start of the project. This is used in digital workflows for precise positioning.

What is rob’s timecode calculator?:
Rob’s Timecode Calculator simplifies the complex process of converting between human-readable timecode (HH:MM:SS:FF) and a single, continuous numerical value known as Total Frames. This conversion is fundamental in professional video editing, animation, and post-production workflows, ensuring synchronization across different pieces of equipment and software.
The calculator is particularly useful when needing to calculate offsets, determine the exact duration of a clip in frames, or integrate time-based events in a system that relies solely on frame counts (like certain visual effects or automation systems). By accurately accounting for the project’s frame rate, it bridges the gap between time and frame data, eliminating manual, error-prone calculations.
How to Calculate rob’s timecode calculator (Example):
- Identify the Frame Rate (FPS): For this example, we’ll use a standard 24 FPS project.
- Determine the Timecode: Let’s use 01:00:10:12 (1 hour, 0 minutes, 10 seconds, and 12 frames).
- Convert Time to Seconds: Convert the HH:MM:SS part to total seconds: (1 * 3600) + (0 * 60) + 10 = 3610 seconds.
- Convert Seconds to Frames: Multiply the total seconds by the FPS: 3610 seconds * 24 FPS = 86,640 frames.
- Add Remaining Frames: Add the final frame count: 86,640 + 12 frames = 86,652 Total Frames.
- Result: The timecode 01:00:10:12 at 24 FPS equals 86,652 Total Frames.
Frequently Asked Questions (FAQ):
A: Non-drop-frame timecode counts frames continuously and is mathematically simple, but it drifts slightly from real-world wall clock time at standard broadcast rates (like 29.97 FPS). Drop-frame timecode skips frame *numbers* (not actual frames) periodically to keep the timecode aligned with wall clock time. This calculator uses the simpler non-drop-frame formula.
A: Yes. If you input a Total Frame count and the Frame Rate (FPS) while leaving the Timecode fields empty, the calculator will solve for the corresponding HH:MM:SS:FF value.
A: The Frame Rate is the critical conversion factor. Timecode is meaningless without knowing how many frames make up one second. FPS defines the rate at which time is segmented into frames.
A: Frames (F) must be less than the FPS value. Minutes (M) and Seconds (S) are typically 0-59. Hours (H) usually have no technical limit but video standards typically go up to 24 hours.
