Jumpy Playback on PC?

     I have been asked about jumpy playback on PC with the GoPro HD2 on numerous occasions recently so I've decided to share some knowledge. Hopefully these tips will remedy the issue.

     If you experience skipping or jumpy playback when you play raw videos from your GoPro to your PC, there's usually nothing wrong with your memory card or your camera. This is your computer's way of letting you know that it is having a hard time playing back the MASSIVE file that you chose. This does not in any way mean that your video is corrupted so please refrain from deleting those precious clips...

     For the GoPro HD2, there are specific system requirements that are truly required for playback at 1080 or 720p resolutions. Those requirements are as follows:
  • For Windows-based computers, we require:
    • Windows Vista or later
    • 3.2 GHz Pentium 4 or faster
    • Direct X 9.0c or Later
    • At least 2 GB of system RAM
    • Video card with at least 256MB of RAM

  • For Mac OS-based computers, we require:
    • Mac OS X v10.4.11 or later
    • 2.0 GHz Intel Core Duo or faster
    • At least 2 GB of system RAM
    • Video card with at least 256MB of RAM
If your PC isn't up to these standards then your playback is going to suffer. But, there's still hope. Compression! If you export your video to a .mov or smaller MP4 file, your video will play perfectly. Here are some sample settings which I find very useful:

Compression type: H.264
Frame rate: Current
Key Frames: Every 30 frames
Frame Reordering: checked
Data Rate: Automatic
Compressor Quality: Best (with Encoding set to “Best quality (Multi-pass)”)
Audio Format: AAC
Sample Rate: 44.100
Target Bit Rate: 96 Kbps
Hopefully these tips will help you solve you playback issues and help better manage your videos!

    I have a PC but XP pro, CoreII Duo - 2GHz, 2GB RAM, a NVIDIA Quadro NVS 135M (I'm sure its the 256 MB model)and I'm still getting jumpy videos. What do you recommend for this?

  2. Specs to play raw video at full 1080p are Windows Vista or later and 3.2 GHz Pentium 4 processor or faster. So right now your PC may still not be able to handle those raw files. But if you compress those raw files they'll play back just fine.
