The GO_HD camcorder is a consumer pocket camcorder that outputs 720P HD video on to an SD memory card. It is available for as low as $217, so it has generated some interest in schools and consumers. I was asked to put it through its paces. This is not a review (that is elsewhere). I have discovered how to handle its files in VP8 which I will list here for you.
The video is encoded in an HD Quicktime file using .h264 compression and AAC audio. iMovie HD will take the files as is. The problem has been what to do with them on a PC. The manufacture just says we are working with NLE developers to help them add support. If you try to open them in Vegas, it crashes the app. Others will have problems with it as well. Quicktime reads the files just fine. Transcoding them in QT can be done, but it takes FOREVER. It turns out that the problem is in the audio. I can't find any bitrate in the files' header for the audio, so that may be the difference that is causing problems but I do not know. Here is what I have been doing.
Open the GO_HD MOV file in Quicktime PRO. Export the movie as an MPEG 4 file. Choose "Pass through" for the video format and use the default or any other audio setting. The key is that Quicktime will not re-encode the video (saving time and quality loss) and it will set the audio with a constant bitrate and the bitrate listed in the file's header. Vegas will now take the file on the timeline without issue. This stream copy of the video with the audio change is very fast.
In VP8 be aware that the GO_HD video is true 30 frames per second progressive, not 29.97 fps. Make sure to set your project properties to 30 fps not 29.97. The wrong frame rate will cause double images (ghosting) on fast motion. Also render to a true 30 fps format for output or you will get strange things with fast motion.
