Getting New HD edit system - feedback?

	Re: Getting New HD edit system - feedback? by Shane Ross on Nov 27, 2007 at 6:02:52 am The AJA I/O HD doesn't do Uncompressed HD. Compressed only, like ProRes. It will play it out, but not capture it. It is really a good PORTABLE box for use in the field with your MacBook Pro. But if you want a good edit bay setup, I suggest the Kona 3 or Decklink Multibridge Pro. And as for the S2VR eSATA Raid...I'd push the HD PRO line really. Not much more and you get much higher speeds, and Raid 5 protection. The S2VR line is Raid 0 only.

	Re: Getting New HD edit system - feedback? by Tim Kolb on Nov 27, 2007 at 3:35:52 pm The two principle factors at work here are file size and file processing load. ProRes compresses the file (and the quality is very good, I'd be surprised if there were quality issues with your images due to compression using ProRes...) which makes the number of bits that the drive has to retrieve and transmit smaller, but decompressing the data to play out and compressing the data to alter and store it (when you create an effect or something that requires a different file to be "rendered" for instance) takes processor power. The system you have specified would be capable of capturing/compressing to ProRes according to Apple's recommendations. The I/O HD is designed to take that processor load off the computer and the box does the compressing to ProRes internally and hands off the already compressed file to the computer. Since you already have a computer that appears capable enough (per Apple) to do the ProRes compression internally, I'd consider simply putting a Kone LHe in the box for about half the cost and have a little more flexibility. As far as storage is concerned, verify what configuration the drive assembly you've spec'd will dependably keep up with your data rate requirements. Most harddrive data rate specs are calculated when the drive system is far less than half full and certainly not fragmented through intense editing operations. Also, keep in mind that most of the more cost-conscious drive assembly manufacturers are quoting data rates based on the very vulnerable RAID 0 (or "striped") configuration. This is a deal with the devil to some extent. The drive housing you spec has 5 drives. To operate at the highest data rate, all 5 have to be striped together from what I can see by the descriptions I've read. This means that the failure of one drive corrupts the entire file inventory in the drive system. I'd take the extra money from switching to the Kone LHe and put it into some reasonable redundant and safe-guarded storage personally.

	Re: Getting New HD edit system - feedback? by Tim Kolb on Nov 27, 2007 at 5:08:01 pm I think Apple has Quadro series cards available as well don't they? ...I'm not familiar with ATI's model numbers, but for QuadroFX, you'd be in the 1500, 1700 range or for dual/dual-link DVI for 30" displays minimum, the higher end cards range from the 3450 (one single, one dual link DVI port) through the 5600 (serious RAM, one dual-link DVI and one dual-link DVI/HDSDI output available) range, with the top end of the range being a considerable investment.

	Re: Getting New HD edit system - feedback? by Bob Zelin on Nov 28, 2007 at 8:05:23 pm This will answer the question - is ProRes422 good enough. The answer is YES. This is the reason. AVID DNxHD is the standard resolution used by countless shows on network TV, and Apple ProRes422 and ProRes422HQ are the EXACT SAME RESOLUTIONS. Anyone that tells you otherwise is giving you mis-information. The AVID Nitris will do uncompressed, but it uses the AJA Xena 2K card, so in your FCP system, you could use the identical AJA Kona 3 card - but I am telling you, you do NOT NEED UNCOMRESSED HD. ProRes (and AVID DNxHD) are all anyone will ever ask for. Bob Zelin Respond to this post   •   Return to posts index

	Re: Getting New HD edit system - feedback? by Ramona Howard on Nov 29, 2007 at 3:56:22 am Bob, but I am telling you, you do NOT NEED UNCOMRESSED HD. ProRes (and AVID DNxHD) are all anyone will ever ask for. Be careful how you state that. Lots still need uncompressed and this very much depends on the job, blanket statements don't paint a true picture. Pretty much all of primetime (what's left of it at the moment) is uncompressed in the sense they are not delivering in a compressed format (yes tape is compressed but that's another topic), VFX work is still and will be for a very long time to come uncompressed and so on....... Offline in DNxHD or ProRes is a great path but depending on what the project is, uncompressed is still very much a needed tool in this industry. What time has given us is a way to do this for less :) Cheers, Ramona Respond to this post   •   Return to posts index

	Re: Getting New HD edit system - feedback? by Ramona Howard on Nov 29, 2007 at 5:02:35 am Good enough is a judgment thing, some will say yes others no.... Only thru your own testing and comparisons will you be able to say for sure. Also source will have allot to do with any of this :) The goal is to not loose any quality (both visually and bits) thru any step of the process, which is why most still go uncompressed, offline editing as compressed with a conform back to uncompressed. All color work staying in uncompressed if possible. I can only speak for the workflows we aid in and not all who are producing for TV.
