You can select your desired clip length.
By default, the Clip Length is set to 30~60s. You can choose your preferred length out of the other options.
If you select ORIGINAL, you will only add subtitles to the entire video without clipping the footage.
If this option is selected, the input video length is maximum 5 minutes.

However, depending on the video, the selected Preferred Clip Length may not be applied exactly.
This is because the clips are created by dividing the video into sentences and then combining these sentences to closely match the chosen length.
If individual sentences are very long, the resulting clips may exceed your selected Preferred Clip Length.
