ex3, Letus Utimate and Convergent Flash XDR
Hi,
For shooting a lowbudget movie beginning of next year, we need two cameras. The result should be transferred to a 2K filmprint and a hd video master. We are thinking about the following setup: Sony EX3 with the the Letus Ultimate Adapter (using rented zeiss prime lenses) and recording on the new convergent design flash xdr box (10 bit 4:2:2 160mbit/sec via HD-SDI) Any opinions? Will this be the best bang for the bug? Thanks for any comment. Holger |

Hello Holger,
Yes, in my opinion, that looks like the best way to go. Alles zer gut. By the way, the phrase in english is "best bang for the buck"! (buck as in dollar) Just thought I would point that out but am sure your English is way better than my German! |

Oh, yes you´re right "bang for the buck",
I think I was just remembering the hardcore adult xxx version of "bug´s life". Sorry for that, I tend to get more easily distracted since I´m dealing with HD formats and compressions. Argh. Holger |

Converget Desing are promising to upgrade their Flash XDR to true 10bit 4:2:2 - how does it hold against your claim that mpeg2 HAS to be limited to just 8bits? Just asking :)

Ah, of course - silly me; being uncompressed, it doesn't need to be mpeg2-compliant any more :)

If correct you'll need a good number of cards (they'll fill up quickly) and you can't re-use them before you've had time to offload then via the XDR (or a second unit maybe). The 50/100Mb and maybe 160Mb I-Frame can be used without RAID and can be read by any CF card reader as I understand it to date. George/ P.S. Convergent Design will share a stand at IBC in Amsterdam this september, Come One, Come All ;-) |

Just to confirm, your understanding is 100% correct. In uncompressed 4:2:2 8/10-bit mode, we stripe the data across all four cards. So you'll need a handful of cards as they fill up quickly at this data-rate (about 1Gbps). For almost all applications, the 100 Mbps Long-GOP or the 160 Mbps I-Frame only will be a more reasonable choice, with very little difference in overall quality. Of course there are some applications were uncompressed is an absolute requirement. Looking forward to IBC where we will feature both the XDR and the upcoming nanoFlash.

another possibility ...

The other obvious route is the Elite HD w/ swappable 2.5 SATA drives w/ 10 bit quantization. At this time, the max 2.5 drives running at 7200 are 320 I believe, so, this is one method that has a future. I don't like the $6,000 price tag on this unit and of course it hasn't been tested yet for all the flaws that will come to light (heat being a major one) but 4.2.2 10 bit is looking to be the goal on all these units. |

Sorry for the confusion, we plan to start shipments of Flash XDR this month and the nanoFlash by 1-Sep.

Also, this same set up would seem to conform to most HD broadcast requirements too. |

or, if you are going for 100 mbit 4 sandisk 16GB extreme III cards are 85 minutes with 4:2:2 100mbit/s which equals 360 Euro per one and a half hours. Sounds pretty good to me. |
