The newest feature added to the GoPro Hero arsenal is the ability to trim and then share or save your videos that you shoot. You have the option to do this in camera using the LCD Bac Monitor or using the GoPro App.
According to the GoPro website:
GoPro is very excited to release its latest feature that further enables users to effortlessly share their memorable moments captured on their GoPro devices. This smart new feature allows the user to create short video clips directly on the camera or mobile device for easy sharing. Simply press the Trim icon in playback mode, choose a 5-, 15-, or 30-second clip from any of your recorded content, and save it for sharing, all without transferring entire video files.
On-camera trimming, available on HERO4 Black with LCD BacPac, HERO4 Silver, and HERO+ LCD, allows you to save your trimmed file directly back onto the memory card, adjacent to the rest of the video files for later sharing. As well, the in-app functionality will allow for instant saving to your camera roll and very precise trimming from all Wi-Fi enabled GoPro cameras.
In order to focus on the run, the set wave, the trail in front of you, typically you would just press record and allow the GoPro to catch everything. However, if you caught some epic content during that session, you may want to set it aside or share it to the world as soon as you stop recording. Before, that required you to download your footage to your computer, find your best moment, edit a clip, export and upload it. With the new Trim and Share feature, you can select that climactic moment on your mobile device and upload it to Instagram while you are on the chairlift headed back to the top, on the beach between sets, or sitting on the tailgate in between laps.
It is a basic edit feature with no frills. There is one problem, it does not do 4K files. Hopefully all that will change with the introduction this week of the new iPhone 6S and 6S Plus which incorporates 4K recording. We will have to wait till September when the new iPhone is released to the public. At that point maybe all of us 4k shooters out there will get some real love from GoPro.
