how to delete photos from iphone 5s

Howdy clickpgt,

it sounds like you have 2 questions. 1) how to delete pictures from the Photos app, and 2) how to sync video that you have on your computer to your phone. For the first question, use these instructions to delete photos or video from the phone:

Organize photos and videos

Delete a photo or video from Photos. Tap the Photos tab, tap the photo or video, tap , then tap Delete Photo or Delete Video. Deleted photos and videos are kept in the Recently Deleted album on iPhone, with a badge showing the remaining days until the item is permanently removed from iPhone. To delete the photo or video permanently before the days expire, tap the item, tap Delete, then tap Delete Photo or Delete Video. If you use iCloud Photo Library beta, deleted photos and videos are permanently removed from all iOS 8.1 devices that use iCloud Photo Library beta with the same Apple ID.

For your videos, you will have to sync them to your phone through iTunes. This article will help you do that:
