Can I use these calculators for broadcast television work?

Absolutely. Our calculators support broadcast standards including drop-frame and non-drop frame timecode, SMPTE standards, and professional broadcast formats.

Timecode toFrames

Convert timecode values to their equivalent frame counts for precise video editing, synchronization, and post-production workflows with frame-accurate precision.

Input & Output Value Types

I
Input Value Types

Start Timecode

HH:MM:SS:FF format

• Starting point for frame count calculation
• Supports drop-frame format with semicolons (;)
• SMPTE compliant timecode format

End Timecode (Optional)

HH:MM:SS:FF format

• Optional end point for duration calculations
• Calculates frame difference between two points
• If omitted, calculates total frames from 00:00:00:00

Frame Rate

TimeBase enum or custom value

• Presets: 23.976, 24, 25, 29.97, 29.97 DF, 30, 50, 59.94, 59.94 DF, 60, 120
• Custom: Any decimal value > 0

Timecode Mode

TimecodeMode enum

• Time of Day: 24-hour format (00:00:00:00 to 23:59:59:FF)
• Freerun: Unlimited hours format for long-form content

O
Output Value Types

Total Frame Count

Integer value representing the exact number of frames

• Precise frame count from timecode
• Accounts for drop-frame calculations
• Ready for use in editing software

Duration (if two timecodes)

Frame difference between start and end points

• Exact frame count between two timecode points
• Useful for clip duration calculations
• Frame-accurate segment lengths

How It Works

This calculator converts timecode values (HH:MM:SS:FF) to their exact frame count based on your project's frame rate. Essential for precise editing and synchronization workflows.

Input Timecode

Enter the timecode value(s) you want to convert to frames

Parse Components

Break down hours, minutes, seconds, and frames from timecode

Calculate Frames

Convert each component to frames using frame rate mathematics

Output Result

Get the exact frame count for editing and synchronization

Calculation Formula

Total Frames = (H × FPS × 3600) + (M × FPS × 60) + (S × FPS) + F

Where:

H = Hours
M = Minutes

S = Seconds
F = Frames

Example:

00:00:10:00 @ 24fps = 240 frames

(0 × 24 × 3600) + (0 × 24 × 60) + (10 × 24) + 0 = 240
