Please note time-lapse video creation is a very resource-intensive task. CameraFTP website can only offer very limited/basic support. To generate high-resolution and high-quality time-lapse video, you can download all image files to a local computer, then use professional video editing software to create a time-lapse video.
To download all image files, you can use any FTP client software, e.g. FileZilla. For info about how to use FileZilla, please watch this video:
