Hi Steve,
Not sure if I can answer all of your questions but hopefully I can give you some valid advice.
Personally, I own a HyperDeck shuttle which I bought to use with my HPX170. I’m very happy with it. The naming structure is easy to use and it’s a fairly simple device in general. Timecode though is not it’s thing and I’m not sure if it can be externally triggered. I think that it can (almost sure but I would look it up), but I’m not sure if it can be triggered from a Panasonic. Worth a test though. In my opinion though, the worst things about the HyperDeck are twofold. 1) It does not remove pulldown. So if your camera outputs a 60i signal over the SDI (like the HPX170 does regardless of framerate), it can’t read the data to remove the pulldown and conform it to 24p on the fly. This can be done in Compressor or After Effects or even Premiere but it won’t do it in hardware. 2) Settings cannot be changed without a computer. You need to plug it into a computer with the software installed to change recording settings.
The Atomos Samurai I’ve had problems with though a DP friend of mine loves his. Though we have had serious problems with it particularly when getting the footage into Media Composer 6/6.5. Not sure if Avid fixed this in MC7. I also am not as wild about the touch screen thing and I don’t think that it auto-triggers but again I’m not sure. It has it’s own timecode I know but unsure if it can use camera timecode. You can change settings in the field though which is nice. The Samurai is sort of the HyperDeck with a screen and more features.
The AJA Ki Pro and Ki Pro Mini are the best out there in my opinion. They are robust, portable, and easy to set in the field. But they are by far and away the most expensive.
In the end, you get what you pay for. All record several 10bit ProRes or 10 bit DNxHD. All will give you a better image than what you are getting internally using AVCHD.
But in the end, you get what you pay for. The HyperDeck and the Samurai both record to SSD’s which are expensive. The Ki Pro uses proprietary digital magazines and the Ki Pro Mini uses Compact Flash, but both AJA units requires broadcast style batteries while the Atomos uses Sony batteries and the HyperDeck has a built in rechargeable battery and can be plugged in. I would do the math and decide what you want to pay for including accessories and media. Full disclosure, I got my HyperDeck while already on the pre-order for the EF mount BMCC. I was already expecting to be buying copious amounts of SSD’s.
