Deleting videos from iPod touch
You can delete videos from iPod touch to save space. Deleting a video from iPod touch (other
than a rented movie) doesn’t delete the video from your iTunes library. It may reappear on
iPod touch if the video in iTunes is still set to sync.
If you delete a rented movie from iPod touch, it’s deleted permanently and cannot be
transferred back to your computer.
Delete a video: In the videos list, swipe left or right over the video, then tap Delete.
