Hyperdeck vs. Gemini

With all of the talk about the Hyperdeck Shuttle recently in this forum, it's got me thinking about the Shuttle as an alternative to the Gemini.

My question is: if one is planning to work with uncompressed files, what do you get for the extra cost of the Gemini? This is a real question and I'm not trying to start a flame war here, just looking for facts.

Specifically:

- Can you transcode directly from the Hyperdeck files (wrapped as .mov I believe) into to your favorite format using Adobe Media Encoder? I know you can do that with Gemini as I have done it successfully on some test files.

If you can, then you should be able to get equally high quality images from both at 422 (not 444 of course!)
Both I believe are low volts and can be powered easily with external battery.

Aside from that, Gemini gives you:

- Monitor
- LUTs
- 444/RGB*

*I'm not convinced I can see a difference between 422 and 444, but does the RGB output into the Gemini add anything?


Anything else I'm missing in factoring in the benefits vs. costs?

Thanks.

[TD="class: midtext"]Well the Hyperdeck eats hard disks for lunch. A 500GB SSD will fill up in 50 minutes. Approximate 8GB per minute (uncompressed 10 bit 30 fps 4:2:2). So don't expect the cheapest SSD will do the job for you, and you need more than one. The offload will take time. The trans coding will take time. To make everything bearable you need the fastest PC/Mac on the market. The initial cost of a Hyperdeck is extremely low, but the aftermath will add up.
Compression, used moderate, isn't a bad thing at all.

True, but that's the same for Gemini. So, assuming one decides to go this route, how does the Gemini compare with the Hyperdeck?
 
Gemini will be way more reliable. HyperDecks are cheap, but that's all about it.
If you can afford you rather may consider Cinedeck, as it offers a lot more, than just uncompressed record.
 
Thanks. Rented Cinedeck -- liked it a lot but fan noise is really too loud to use on-camera and it's large and eats batteries.
 
Hmm- if you do 24p with low noise camera you should be happy with ProRes quality and than there is bigger/cheaper choice.

Hyperdeck files are v210 MOVs- no need to transcode to anything- this will work in all grading tools and in every NLE.
It's generic YUV 10bit 4:2:2 format.
For 5K you can also build your own recorder :)

I am sure you know, but the fan can be turned off while recording. It does eat the batts however, but small price to pay (my thoughts)

Thanks. Right now my goal is to convert to Cineform before editing to both save space and take advantage of First Light.

Thanks. Didn't know you could turn it off totally (does it run the risk of overheating then?), but, regardless, it's too large and heavy.

It has a built in over-ride, so if you have the fan off, and the temp gets too hot, it will come on. However, I have yet to see it happen, and I've ran some long record times.

Good to know. No doubt, Cinedeck is a very fine recorder!
