Nu-Movie Player Export video is a multimedia player for iPhone that allows users to control the speed and pitch of videos in real-time. It is compatible with video data stored in the standard apps "Photos" and "Videos". The app offers a free trial for the first movie export, after which an In-App Purchase is required.

One of the main features of Nu-Movie Player Export video is the time stretch function, which allows users to change the playback speed of videos without affecting the pitch. The speed can be adjusted between 50% and 200%. For those who need more flexibility, an In-App Purchase can extend the speed range up to 12.5% to 800%.

In addition to controlling the speed, the app also offers a pitch shift function. Users can change the pitch of the video without altering the playback speed, with a range of ± 1 octave.

Nu-Movie Player Export video also enables users to save and export the modified videos. The exported videos reflect the set playback speed and pitch changes, and are saved in the camera roll.

Please note that the app requires access to your photos and media library, which you can grant by pressing "OK" when prompted.
