Need to crop or add zoom to a video after the fact? Try Video Zoom
Video Zoom (US$1.99) is a just released app that will let you take an existing video and crop it, or add a smooth zoom. The app also lets you record a new video from within the app.
Give the app access to your camera roll, and you will see thumbnails of all your existing videos. Tap a thumbnail and the video opens. Use the pinch/drag gesture on the screen to zoom in. It works when the video is running or when it is paused. If you set the zoom when paused, you will get a smooth zoom in when you playback the video.
When you are done you can save the zoomed or cropped video as a copy, or overwrite your original.
I tried the app on 4 videos I had on my iPhone. I was afraid the zoomed video would look pretty bad, because the app can't keep the same resolution after the zoom, but actually, my tests showed the video looked pretty good and was not overly pixelated.
When recording, you can use your iDevice front or back camera, and the app supports the regular iOS photo library.
Video Zoom is a good idea, just the app for removing that obnoxious cousin from the side of the Christmas video...
Video Zoom is a universal app, and it is optimized for the iPhone 5 and 6 series of iPhones. It requires iOS 8 or later.
