+
+You can make multiple changes to the video, including adjusting the voice settings, adding or removing segments, and changing the time frame of the scripts. You're only charged after you select **Apply changes** to apply your changes. You can select **Save** to save work in progress without incurring any charges.
+
+If you encounter segments with an "unidentified" voice name, it might be because the system couldn't accurately detect the voice, especially in situations where speaker voices overlap. In such cases, it's advisable to manually change the voice name.
