There seems to be some confusion, Aspect HD does support capture using the Xena card, only Prospect HD does. This is no way affects the DS or VFW codecs.

I just read the thread and gained more confusion! Tim (or anybody), could you answer me this? A Blackmagic sales/support person told me the multibridge takes away the need for their capture card. Is what you did possible with just this and you used the card because it already existed in your rig?
I would be pulling my hair out if I had any! |
Rich,
Who is your question for? Maybe you can re-ask. What are you hoping to achieve, and what system to you hoping to use? |

They're wrong. The standard "Multibridge HD" interfaces with the SDI in and out on the Decklink HD. The multibridge converts analog sources to digital SDI and vise-versa. The sales person may have been referring to the fact that Blackmagic is now bundling the Decklink Plus card with the original SD multibridge, and a PCI Express card with the Multibridge Extreme (for SD & HD.) However, you still need at least a Decklink HD to interface with the standard Multibridge HD. Or maybe I should say you need a Multibridge HD to use analog signals with a Decklink HD. |

Any ideas? Thanks Duke |

If you want to capture the component HD signal and you are Mac based, you could capture directly to DVCProHD using AJA's KonaLH card (the one with the analogue component HD interface), but you would need a G4 or G5 on location as these cards require a PCI slot. I don't know if anyone here has tested that setup so it would pay to do that first. |
and uncompressed?

Thank you. |

For my take based on the website information it will digitise to any Quicktime format (both in 8bit and 10bit and it will downconvert on the fly to SD) BUT DVCProHD is the only one that is supported by hardware compression on the card (or the only one they advertise). So to digitise to another codec you need: 1. one that supports JVC's HD60P format, 2. and then if it's a compressed codec you need a LOT of processing power, 3. if it's uncompressed you'd need a fibre channel RAID system and a LOT of storage, all of which can be problematic. It appears it does support HDV playback in hardware. |
I understand
Thank you.

But if you plan to shoot to tape and ingest afterwards and from the sound of it you do, then all you need is plain old firewire 1394a port and software capable of digitising it - that would be by far your best option. What is your plan for a tape deck? That seems to be the biggest hurdle with the Canon. BTW this forum is for the JVC so not too many here actually using the XLH1 |
I'm also looking to move up. Since my PC died last night, I am going to have to do this sooner than I expected... I'm looking at the Xena HS and the Decklink HD Plus, both under $1,000. Now, I'm trying to figure out what else needs needs to be replaced. I need a PCI Express for either capture card, but find nothing with PCI and AGP to support a regular video card. So, will I have to replace a brand new AGP card with one that can use a PCI x16 slot? Whatever that is...

Bottom line is you don't need a capture card if you already have firewire on board (a lot of motherboards do). If you need a 3rd party card buy SIIG, preferably PCI-x if you have slots on your intended target machine. They seem to be qulaified by most NLE's. |

http://www.asrock.com/product/939Dual-SATA2.htm I can't recommend this board, it has got good reviews but in the past this manufacturer has made some duds, plus it is an Athlon board so if you have an application that requires SSE2 support (eg Encore DVD2) your SOL. If you do go completely PCIe the catch is you need a board with at least 2 x PCIe16 slots - one for video and one for your capture card.Some MB's only include 1 slot assuming you'll use that for your graphics card. I would recommend upgrading the video card OR going for the Xena LH which only needs PCI-X (which is not to be confused with PCI-Express (Xena LHe). I would also suggest you look at the Decklink HD Extreme ($US995 list) rather than the Pro -it has analogue inputs as well and comes in both varieties PCI-x and PCI Express. The only advantage the Pro has is if you have a deck which supports dual link HD-SDI you can ingest 4:4:4 footage. The extreme is 4:2:2 only. I would suggest if it is at all possible you see a demo of these cards and their software functionality before making a decision. |
