best codec to capture HDCAM with a Aja Kona LHe
Hello,
I would like to have your advice on which codec to use to capture HDCAM footage, directly from the camera using an Aja Kona LHe.
The Aja Kona LHe is only 4:2:2, I was thinking using Apple ProRes HQ.
Since I read that there is some bug with ProRes, I was thinking using 10-bit uncompress. Even if the card is only 4:2:2, I think graphics and text will looks better.Also, which raid system do you recommand to handle it? I started to look the G-Speed XL 16TB with 2B of cache with fiber channel.

What bug? Please expand on that one…
ProRes would certainly allow you to use a much less expensive raid that 10-bit uncompressed.

I recommend the Caldigit HDPro. 4 times faster than Fibre channel, and pretty rock solid. I have a review here at the Cow. They have a cheaper version called the HDOne…jsut as fast, just slightly less features and redundancy.
Also look at Sonnet 800P and Maxx Digital for solutions.

We use uncompressed 10 bit 4:2:2 with a Cal Digit HDpro. Although HDCAM is only 8 bit, we prefer 10 bit for VFX and Colour correction, however I’m not sure how much difference it really makes.

It was on another forum, they just said there is bug with the ProRes without to give any precision.
Thanks all for your answers.

ProResHQ. Uncompressed 10bit is a bit of a bear to work with on an editing basis. Great to finish with but not to edit.

Capturing straight off the camera is a potential disaster. The editing codec is one question but the real problem will be the ability to recapture.
Straight off the camera will give you no device control and therefore no timecode if you recapture.
Uncompressed is huge so unless this is a very short project you will rapidly fill expensive RAID drives. I use uncompressed to recapture final edits but never would consider it for editing.

Using the LHe and AJA VTR Exchange, you should be able to pick off the RP188 tc.
If not, you can use on ioHD that will either pick off the rp188 or you can send LTC to it and capture that with a laptop and a 2 drive SATA array (I have done this and it is awesome). You get hardware ProResHQ encoding with the ioHD.
OR you can use the adreilec mbox https://www.adrielec.com/
It’s not as hard as you’d think and can be done on a laptop now-a-days.

Interesting Jeremy. Thanks for that. I hope Martial and others take note.
However, my experience so far is that uncontrolled device is the way editors have so far dealt with this type of capture and of course I get to find out about it months later doing the online.
