How does shortshort decide where a short starts and ends?
It reads the transcript of the whole video and looks for passages that make sense on their own: a question with its answer, a claim with its example. The cut is placed on the first and last word of that passage, so the short opens and closes on a complete sentence rather than at a fixed second.
What does the 25% margin mean in practice?
The 25% margin is the room the AI has to finish a sentence. If you ask for 30-second shorts, each one may run between 22.5 and 37.5 seconds. If you ask for 60, the range is 45 to 75. The target is a guide; the sentence boundary wins.
How many shorts can I get from one video?
Between 1 and 20 per video, each 15 to 90 seconds long. The ceiling depends on your plan: 3 on Free, 5 on Starter, 10 on Creator and 20 on Studio. Whatever the number, the video costs 1 credit per minute of source.
Does it rank the shorts by how well they will perform?
No. shortshort does not compute a performance score or predict views. It proposes passages that are complete and quotable, and the order and the final choice are yours. Each short comes with a title the AI wrote for it, which is the quickest way to pick.
Can two shorts overlap or repeat the same moment?
No. Selected passages are kept apart, so each short is a different part of the recording. If you want a second version of the same moment with a different length, adjust the bounds of that short by hand in the studio and render it again.
Is this a separate tool from the shortshort editor?
No. Sentence-based selection is the first step of the same shortshort studio: the AI proposes the passages, and the same page lets you change the cuts, the framing, the captions and the title before you export the MP4. The AI step needs an account; manual editing does not.
