Where the request belongs
Work Crossfade Time Subtractor can move forward.
This is for the video editor who's tired of doing manual math in their head while trying to hit a 30-second mark for a client. It's also for production managers who need to know exactly how much raw footage to order to hit a specific final duration.
Video Editor
Uses this on a Tuesday afternoon to figure out if a complex 10-clip montage will actually fit into a 60-second social media slot.
Production Manager
Uses this to calculate the total raw footage sum required for a commercial to ensure the production team orders enough material.
Content Creator
Uses this to quickly check the final length of a sequence with heavy overlapping transitions before exporting.

Before you connect
Questions about Crossfade Time Subtractor.
The practical details behind the request, access and result.
How does Crossfade Time Subtractor help with video editing?
It calculates the precise length of a video sequence when clips overlap. It takes the math of your crossfades into account so you know exactly how long your final edit will be.
Can I use Crossfade Time Subtractor to figure out footage needs?
Yes. You can tell your agent your target final duration and how many crossfades you plan to use. It will calculate the total amount of raw footage you need to have on hand.
What is the difference between total clip length and true duration?
Total clip length is just the sum of the files. True duration is the actual time the viewer sees, which is shorter because crossfades cause the clips to occupy the same space on the timeline.
Does Crossfade Time Subtractor work for any video software?
It works with any AI client that supports MCP. It doesn't replace your editing software; it provides the calculations you need to use within any NLE like Premiere, Resolve, or Final Cut.
How can I use Crossfade Time Subtractor to plan a 60-second commercial?
You can input your planned clip lengths and transition times to see if the sequence hits the 60-second mark. It helps you adjust your edit before you start the heavy lifting of syncing.
Does Crossfade Time Subtractor calculate the math for multiple junctions?
Yes, it can analyze a whole sequence. It tracks every junction to give you a total impact report of how much time is lost to transitions across the entire timeline.
How does Crossfade Time Subtractor help with production budgets?
By calculating the exact raw footage sum needed for a specific duration, it helps you avoid over-ordering expensive raw material from production houses.
How does the duration calculation work?
The capability 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 capability will return an error to prevent invalid calculations.
