How does the duration calculation work?

The tool calculates the total sum of all clip durations and then subtracts the cumulative time lost at each junction. The number of junctions is always one less than the number of clips.

Can I use this to plan my footage requirements?

Yes, by using `get_required_raw_sum`, you can determine exactly how much raw clip length is needed to hit a specific target duration after all crossfades are applied.

What happens if the crossfade duration is too large?

If the `crossfadeDuration` exceeds the length of any clip in your sequence, the tool will return an error to prevent invalid calculations.

More Details Connect to Claude

The Crossfade Time Subtractor MCP server provides essential calculations for video editors working with overlapping transitions. When clips crossfade, the total timeline duration is shorter than the sum of individual clip lengths because segments occupy the same space. This tool allows you to use get_true_duration to find the actual visible length of a sequence, get_required_raw_sum to determine how much raw footage is needed for a target duration, and get_overlap_impact_report to analyze time lost to junctions.
