Hero 2 vid issues Can't Post

Hi guys. Just wanted to post my issues and gather any information you may have as well. We have a few new gopro hero 2's at our dz and we have found that the video is a bit of a problem during editing. We have Sony Vegas and Adobe premiere. We found that there is a lot of pixel-ization (if that's a word) in the sunny spots in the sky or the water. Also, it's when there is a bit of jiggle the shot looks blurry. We've tried a few different modes and fps but it's still an issue. Totally bummed cause the colors and sharpness is excellent compared to the original hero HD's. Premiere runs really slow cause of the frame rate if we use 50, but it helps with the pixelization if we use 50 (?)
The photos however are awesome. In 5mp's in the 1/2 second mode they are sweet, and the colors are much better than the hero HD.
Has anyone else used these yet and run into any problems or encountered a way to fix them? (please don't say use another camera- I'm trying to see if there is a way to fix this issue with this particular camera)
Cheers!

I've been using a GP2 for handcam over the last few weeks, and I haven't experienced the pixel issue you're describing. Mine is set to 720p 60fps. Can you post a video example of the problem?

Jiggling will always be an issue with these cameras if they're bouncing around while recording. The videographer needs to be steady while shooting to get some good footage. it takes some practice to learn good shooting habits with GoPros and probably with other small format cameras.

Yeh, the biggest problem is under canopy when the slider is flapping and the TM can't reach it, we didn't have as bad of a problem with the original go pro Hd's though

now i"m confused.
You see the pixilation in the source (straight off the camera to a monitor) or in the render (Vegas or Premiere)?

If you're seeing this in the render but not straight from the camera, it's in the render settings you're using, could be you've added some FX somewhere, lots of possibilities.

Hmmm... You shouldn't be seeing a downgrade in quality with GP2. Just out of curiosity, what's the firmware rev on your cameras? It's listed in the misc folder on the card.

Sorry, yeh the render in Premiere comes out well but during editing the source is slow. The render in Vegas has pixelization.

This isn't a problem with the camera; it's user-error.
Rendering to same bitrate, format, resolution should give you two files that appear exactly the same from any application.
What is you render-to format?
Bitrate
resolution
compression/codec?

Thanks thats excellent news! I'll have to ask my tech guy. Do you know if I'll have to change it every time I edit a gopro hero and then a hero2, or is there a happy place codec that will do them both? Cheers.

The firmware and settings on the card say :
"info version":"1.0",
"firmware version":"HD2.08.12.38",
"camera type":"HD2",

Thanks guys, I think I'm getting closer to resolving the issue. These forums are a great to way to gain information! :)

Both apps natively support AVC. If going to DVD, they'll be *slightly* different as Vegas has its own kernal that drives the encoder, so it's a higher quality encode at similar bitrate than Adobe Media Encoder.
That said...if you're rendering to a 1280 x 720 12Mbps or 1920 x 1080 at say...16Mbps for web delivery, both will delivery a very similar image without touching the dynamic range. Vegas offers a plugin for DVD encoding that will limit range if necessary (broadcast plugin)

When the slider is flapping, tell your TIs to squeeze the front & rear risers together and give them a good shake. The slider will rise up at the front and re-inflate & the flapping will stop.Wink

nah, makes no difference (unless for some reason you're using Constant Bit Rate).
