FAQ
Questions Crossfade Time Subtractor owners ask.
- 01
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.
- 02
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.
- 03
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.
