Mastering Video and Audio Timestamp Math

In timeline editing with DaVinci Resolve, Premiere Pro, or Pro Tools, finding cumulative sequence runtimes or trimming timestamps is essential.

Cumulative Clip Length Calculation

When stitching 5 b-roll sequences:

• Sequence 1: 00:04:12
• Sequence 2: 00:08:45
• Sequence 3: 00:02:18
• Sequence 4: 00:15:30
• Sequence 5: 00:01:05

Using Time Addition Calculator’s HH : MM : SS mode yields an instantaneous total of 00:31:50 without manual base-60 scratchpads.
