We have a few things for you to try that should help clear up the choppy playback issue you’re seeing on your computer:
- 1. Make sure you copy your videos to your computer’s hard drive from your camera’s SD card before you play them back. Playing back videos from your SD card can result in choppy playback.
2. Play back your videos with VLC Media Player. This is a free program that doesn’t take up a lot of resources to run on your computer. This means that your computer can focus more on playing back your videos smoothly. We've found that it's common fro Windows Media Player to give you choppy playback, so we recommend against using it. You can download VLC Media Player here: http://www.videolan.org. If you’re looking for a quick fix, you might want to skip down to Step 4. Windows Media Player does not support playing back HERO3: Black Edition video resolutions higher than 720p 120fps. This means that 1080p resolutions and higher will not play back. You'll hear audio, but you won't see any video.
3. Make sure that your computer meets the minimum system requirements to play back videos from your camera.
For lower resolution videos (1080p 30fps and lower): We recommend at least 2.4 GHz processors and 4 GB RAM to play back lower resolution videos (1080p 30fps and lower).
For higher resolution videos (1080p 60fps and higher): We recommend at least 3.0 – 3.7 GHz processors, 4 GB RAM, and a graphics card comparable to an NVIDIA GeForce GT 650M. The graphics card and processor speed is important particulary for 4K and 2.7K resolution video playback.
Here’s how you can check if your computer meets the minimum system requirements:
Click the “apple” icon in the top left corner of your screen, and then click “About this Mac”. Next, click “More Info…”
Click on the Start Menu, then right-click on the word "Computer" or “My Computer”, and click “Properties”. Once you have done this, scroll down to the System Information for Processor and RAM. You can find your graphics card by clicking on the small arrow to the left of “Display Adapters” in your Device Manager.

4. Turn OFF Protune and record in a lower video resolution. If your computer can’t play 1080p 30fps smoothly, try recording videos at 720p 30fps instead. The lower resolution means that your computer will have less work to do when playing back the video, so it’ll have an easier time giving you smooth playback
