HD Camcorder (60fps), Firewire for streaming application to a Mac Mini

[joedom]

We're trying to put together a video capture system for a company that will be video capturing people running on a treadmill. We're currently using a Mac Mini, Sanyo Xacti VPC-HF1 and an HDMI video monitor. We're using 60fps so that the video can be stopped and reviewed with high quality images. The probably are "wrinkles" that show up on the bottom of the video capture. We believe it's probably because the video is streamed over USB 2 instead of Firewire. Assuming that 's the case, we're looking for a camcorder recommendation that keeps the high quality (60fps) capability, but with Firewire transfer instead of USB. Suggestions? Thanks!

What software on the Mac Mini?

1080i (59.94 fields per sec) HDV over IEEE-1394 is directly supported by iMovie. 720p/59.95 is not.

Thanks for the quick response. We're using QuickTime.

So have you tried 1080i and found it lacking?

I'm unsure of what you are doing. I assume you are shooting the video, then accessing the file over USB, then importing into Quicktime, then what?

With a DV or HDV camcorder you can capture the live stream in iMovie with live preview, then scan the timeline.

What is the HD requirement?

We are streaming the video via USB using quicktime. The video is being captured and immediately being played back for "frame by frame" review

Have you tried a DV or HDV camcorder IEEE-1394 to iMovie?

I didn't see this posted earlier, so need to give you a little more information. I do have a couple noob questions below, as I am just trying to understand things a little better. Thank you for your assistance so far.

1. Video currently being streamed by USB connected HD camera to Computer
2. Computer is connected to 46" LCD and is on display. Quality of image from camera is very important
3. QuickTime is capturing the video and playback step by step
4. The "wrinkle" occurs during live streaming. If movement is too quick you will see the break in the live segment. It is very visible on playback because under frame by frame observation, you will land on a frame where the "wrinkle" occurred.
5. Must have 60fps or higher for the desired application
6. HD Quality a must

Do you think that QuickTime is the problem? Will it not handle streaming video?

Would we still need an HD camera to get the same quality image and fps we have now? Does that even matter, as it is being used like a giant webcam and applications are responsible for image quality and fps?

If the wrinkle can be seen "live" and that is why it is on playback, is it because we should be using a faster connection than USB?

Hi folks !

I came to this thread this morning because I was looking for an HD Camera witch can stream in HD directly to a computer.
I read that you where making this with the Sanyo FH1 Camera. So I went buy one to test that (I need it for an Augmented reality project). I have tested and all what I achieve is to capture a poor 640x480 stream without any option to change any settings.

Could you perhaps explain me the way to capture in full HD with QuickTime ?

Thanks a lot ! Tobias.
