A client asks for a longer final product shot without changing the whole video. This Shorty browser test started with six supplied fragrance clips. The first export used four shots, each lasting two and a half seconds. The revision brief kept those shots in the same order, shortened the first three to two seconds each, and extended the final bottle trio to four seconds. Both actual ten second exports are shown side by side. The output was vertical ten eighty by nineteen twenty at thirty frames per second. The first ready result was observed about fourteen minutes and nine seconds after submission; the revision about five minutes and fifteen seconds after submission. Those are observation intervals, not exact server processing times. Both exports were silent as requested. The initial estimate was one hundred thirty two credits; the final charge was not verified. This is one first party test, not an independent benchmark. Descript and CapCut also support editing workflows, but no same footage competitor run was performed here. The practical takeaway is to state what must stay fixed and specify exactly what should change.
