There is a free player called VLC (yes, they have a Mac version as well) which allows you to adjust playback speed.

We tried various settings on Don's Sprite a few months back & I found that 720p @ 60fps was SIGNIFICANTLY better while driving compared to all other resolutions @ 30fps. The picture was much sharper & smoother. Even uploading it to youtube where it is scaled back to 30fps (when I last researched this) provided a better overall sharpness to the video. Don didn't notice a difference, so it may be in the eye of the beholder.

There are were a few youtube videos I saw a while back (ones that review various hd cams) that show side-by-side comparisons of 60fps vs 30fps that seem to support 60fps provides an overall clearer picture, especially when panning, etc.

It looked like Henry had his camera in a sock ... might have to try that next time to get better sound.

Do you have a link to the VLC program?

First few shots are Samples showing how the rest of the shots can be Cropped/Enlarged/Color & Density corrected.

Arthur after finally breaking 60 seconds during X Runs ...

So Mako, the trick to getting the balance of the photo's so I can download them and share them with friend is?

Ok first time using the GoProHD. One file worked one was unrecoverable. Why it broke into two I don't know yet. Beause of the way the camera was mounted I have an annoying clicking. Using Mpeg Streamclip I have edited the length to one run and removed the original audio. The question now is how do I add back music to go with the video so it's not a silent movie?

Thanks

I couldn't find my GoPro HD vids clips ... except in iPhoto. Then I discovered that although the device wasn't showing up on my Desktop ... it WAS there ... "under" my home computer device icon?!

I could then download the files ... and open them with VLC or QuickTime ...

for the unrecoverable file try running check disk/scan disk to fix it.

Download a program called "VirtualDub" (freeware). See if you can load the corrupted file into there. Scan/check disk usually won't fix corrupted camera recordings - that's typically due to the way the video files are written. If you can open it in VirtualDub, then you can export into an alternative format for video processing.

As for why it broke into 2 pieces, did you just leave it on for a very long time? what are the file sizes. Some cameras will automatically split files after a certain GB has been reached (either due to codec limits or ease of video processing), though I think GoPro just keeps on recording in 1 file so long as the SD card is formatted in NTFS.

Took me awhile to figure everything out but finally got my first GoPro HD video assembled and uploaded to you tube. The music is cheesy I know, but the original audio was worse as the camera case was clicking on the windshield, that and I have limited selection of even remotely applicable music tracks. So here is my first time out of the box.
