How to "trim original" video in iOS?
When iOS first came out I remember there being an option to "trim original" video where the entire video would be replaced with only the part that you wanted to keep (the trimmed parts of the video would be deleted permanently). You also had the option to "save as new clip" which would keep both the original video and a new file with the trimmed parts removed.
Where has the "trim original" feature gone? It does not show up in the latest version of iOS 8 but it is still referenced in the iPhone User Guide for iOS (see attached picture).
The picture below shows the options I get when attempting to trim a video in iOS 8. You can see that the only option I get is to save as a new clip.
