Or you can get one of these

And yes, the read speed is 1.52 gigabytes/s, not gigabits.

What is an example of a very special raid? Would a normal 7200rpm sata drive deliver the required stream for playback?

To play uncompressed HD you need four drives configured in a raid-0. This makes one very large and very fast drive. In some cases three drives may work for a short period of time. This is for a single layer of video. If you want two layers of uncompressed HD you may need a eight drive raid-0.

I am so sorry!

Please excuse me, I didn't see your "Here". I just saw it and downloaded SP2.

Thank you very much.

Regards,

Jose

Sorry to take your time, but I need some BIG HELP!

I must format my C drive and reinstall my Pinnacle Liquid Pro 6.10 (build 4190) with SP2 (4352).

I have everything except Liquid 6.10 SP2 which I may have lost along the years, and I can not find it anywhere in internet.

So, is it possible to some of you to send it to me, or give me a link to download it? I must finish 2 big projects, so I need this SP2 to be installed, just like before formating my C harddrive. By the way, I work with XP Pro SP2, I don't know if this makes any difference.

Thanks in advance.

Thomas,

Thanks for the explanation regarding how compressed and uncompressed are handled. I always enjoy learning new stuff. It will be interesting to see how things shake out with Chrome vs. NextGen (hopefully within the year).

Compression is what eats up the cpu. The harder compressed something is the more cpu power it needs. Uncompressed needs very little cpu power since there isn't anything to decode. That is the tradefoff in the video world. Either you need a lot of cpu power but the video takes up very little space or the video is huge and uses little cpu power. Uncompressed HD needs drives that can pump a constant 130 MB/S which is a lot of data. You need a very special raid just to even play back a single stream of video. If you want to edit 2 streams of video in realtime your raid needs to handle 300 MB/S without any hicups. People do have this and when they do Chrome runs very well. Sure the rendering could be faster with multithread support but it isn't nearly as bad as it is for those who use highly compressed formats such as HDV.

Another factor to consider is that for many Chrome users they may never need to render anyway. If the timeline can playback in realtime then they can just record back through SDI live and not have to render. I used to do this a lot for a TV show I produced. The entire show was color corrected with titles and bugs through the half hour show. I never once had to render. As soon as I was done editing I just recorded it right back to my deck live from the timeline. Of course not all effects will be able to do this but if I did have something that was too complex to play without dropping frames I would just force render that section. I usually know what sort of effects are going to play in RT and which will not.

Thomas (Smetvid),

So from what you are saying, Chrome (Liquid with I/O hardware) could carry on as is? I admit that I don't know too much about formats and encoding as applied to uncompressed material, but knowing that uncompressed is a huge flow of information, I would have thought that handling uncompressed material could be improved by getting the full benefit of multi-core CPU's and new operating systems (e.g. Windows 7). This would require an update to the base code of Liquid, which apparently is not supposed to happen (not until NextGen, that is).

Chrome Xe still has a bit of life left in her.

Basically the reason why it works so well yet is because most people use it for uncompressed material. Uncompressed is very easy and fast to render and your only limitation is the size of your raid. Format support usually isn't a concern either since most Chrome users use SDI or HD-SDI. SDI doesn't really care what the format on the tape is. As long as any new format has a deck/camera with SDI then that format will be supported under Chrome. It is only the consumer formats that really have an issue with Liquid and most pros wouldn't touch that stuff with a ten foot pole.

So Chrome still has just as solid as a workflow today as it ever did due to uncompressed and SDI. Pretty much nothing has changed.

Chrome does suffer when it comes to encoding different formats and this is the one area where it could use a bit of work. In a multiple system environment however the NLE system is hardly ever used for that purpose even if it did have decent fast encoders built in.

Interesting comment. I am not sure what it may mean in the long run, and I definitely won't ask (and you won't tell!), but if Liquid is not changed soon, even the pro part (Chrome?) will fall behind the fast moving technology in both computer hardware/software area and the recording media/codec area.

Ok, don't ask, don't tell.....

but Avid is currently re-thinking the decision of ending the Current Liquid line (only at the pro end), decision (athough we may or not hear about it), will probably be made over the next 3-4 months.....
