Back to the poll…We are using SATA hard drives. The capital just isn’t available for LTO at the moment. I have to say, it feels like a cheap, inadequate, temporary solution.
The whole P2 system we are using, with the inexpensive HVX-200, is a way to offer HD to some of our clients with a very small investment. The camera has no HD tape mechanism. The VTR for playback is rented. That gets you in the game really cheap.
I need to look for a better enclosure for the backkups. A 2-bay, removable, RAID-1, with FW800 and/or eSATA would seem to be a good backup system for making double copies.
The Exabyte DLT looks interesting, but the transfer rate–6 MBps? That’s 140 minutes to transfer 50GB. The Blu-Ray might be faster than that.

Nice synopsis for the workaround.

It’s hard to beat the 720p60 when smooth motion is your goal. I can’t think of any gotchas for your scenario.

Yep. No problem here.

Read the chapter on Media Manager first.

Now that’s freaky. I was about to say nearly the same thing. I have a Slovak friend who has carp for Christmas. I wonder if they have a Creative Carp community over there.

Sean, I really appreciate the feedback. It has been interesting for me. Hope chrispy doesn’t mind the diversion of the thread! One area about which I have not yet found much information on the web is the way that LCD and other progressive displays process video. What are their refresh rates? What exactly is refresh rate? I’ve heard it said that most flat panels have a 60Hz refresh rate. Does that mean they put a new image on the screen every 60th of a second? Is there a period of time when the screen is black between frames? When you say an LCD displays 1080p30, does that mean that the panel has a 30Hz refresh rate? Or is it storing the frame and then displaying it twice at 60Hz? Little bits of this have been mentioned on the Cow and other places, but I need MORE. I don’t expect to find that knowledge right here and now–just making mention of the subject. Thanks for all your effort on this topic.

I’m lost. Or am I? I guess time and more study will tell, but I think I see this the way Jeremy is describing it. To me, the Kona is doing the only thing that makes sense to do with the 720p60. The result is that each frame is made into a field for the 1080. Each field is half of the frame. They are interlaced on playback. They are deinterlaced by the display monitor. A good monitor will use some sort of motion adaptive or motion compensated deinterlacing algorithm.
To my mind, 1080i is always going to be, in effect or in a manner of speaking, “540p60” as it is displayed on a progressive monitor. That is only a way of verbally describing the deinterlacing that the monitor is doing. If a camera is to record 1080i it will record fields that are half the resolution of the full frame. The fields will always be interlaced. As a result, any motion that happens during a 60th of a second will create some sort of artifact. If the camera shoots a still object, it will appear to have the full resolution and the deinterlacer in your monitor will loaf along using weave. If the camera moves, the deinterlacer will have do some fancy stuff to avoid ugly artifacts.
One interesting point that all of this brings up is that any of the formats that sacrifice frame rate to achieve progressive frames (24P and 30P) also end up preserving all 1080 lines of resolution at all times (as long as you keep them away from interlaced NTSC displays). But at the expense of motion smoothness or frame rate. Right? Ha ha, lucky I’m capturing hour-long clips today.

Thanks Tim. It could be something simple, on up to the latest gadgetry. If it gives Creative Cow another edge, so much the better. In the meantime, I’m still happy to simply do a search and collate the results myself.

Here are some ideas for the format:
-Easy to recognize or remember or make it a sticky post
-Same format every time
-Contains a scorecard of what works and doesn’t work-Can be contributed to by users in some way
(Maybe a form that keeps track of entries made and keeps a running hit counter for bugs on, say, the “X” plug-in.)-Has a color code for “Stable”, “Shakey”, and “Awful” or variants
It’s an extension of the recent sticky post about Adobe CS3 and Leopard. An at-a-glance way to get the scoop on a new system. I thought this thread was useful for the purpose, but later on, we’ll have to search for this and we might get conflicting info from earlier threads.
