I just tested it and it seems to be fine. Could you please email us screenshots showing your problem? We need to know how you generated the timelapse video (which parameters you entered), and the generated video.
Time-lapse video creation is very resource intensive. CameraFTP only offers a very basic and limited online tool. We recommend downloading your files and generate timelapse video using a profesional time-lapse creation or video editing application. Please read this support message:
