Solid State Drives?
 
Has anyone here used any of the new Solid State Drive's for editing?

The largest that I found was 64GB. Relatively expensive compared to normal HD's but maybe they would help the workflow editing in Edius 5 AVCHD files.
Just a question. They can be used in a raid I read.

I was thinking if one coupled the SSD's with the intel core i7 and DDR3 ram with the right Graphics card it might help to edit native AVCHD? any thoughts?

The SSD's run relatively 3 times faster than Sata II which translates into a very efficient Raid 0. I did a review on a pair in Raid 0 just recently using Premiere and there is a noticeable difference in efficiency.
At the moment unit cost is way too high and size far too small to make it economic. But who knows what will happen tomorrow?
Unfortunately I needed to give the drives back.

I would like to buy the Panasonic HMC 151(pal) camcorder but I want to be able to edit the AVCHD files natively and have a fast ingest. I like the camcorder because of its low light capabilities.

So I thought I would build the fastest computer that can be built to edit in Edius 5.

I hate waiting for anything to load, boot, transfer. I would go the P2 route but I haven't found a good low light camera.

you wont get better than a SONY EX1/EX3 - i can film with a candle!
(or wait for the new JVC HM100 solid state camera due in April)

PS - AVCHD slowness has NOTHING to do with Hard disk speed - its a processor thing - just avoid AVCHD if u dont want to convert it to an editable file type

The problems are not the drives with AVCHD but the cpu.

So even with solid state drives you will have the same issues and the cpu can't decode it fast enough.

AVCHD is encoded max at 24 mbit = 3 Megabyte per second . Any SATA hardrive can handle that times over.

That's the reason you can write it to : SDHC or dvd while recording on on the camcorder.

I just thought the transferring of the files off the cards would go faster.

The new Intel core i7 with the better handling of memory and all won't this help either?

SRsupport 02-11-2009 01:29 PM

Transfer will be as fast as the read spead of the cards you are off loading . So if the cards can only be read at lets say 4 MB per second ...you get the picture.
(Maybe solid-state drives would help if you would transfer many cards at the same time)
Don't know if The Intel core i7will can decode AVCHD fast enough for it to be realtime,
If fast turn around is a must for you I think it is better not to invest in AVCHD.
For now you will have to covert it to HQ for smooth editing.
AVCHD is too compressed.

The video I do is mostly of horses and training sessions and lessons.
For 45 to 60 minutes at a time. Then we like to look at the footage an analyze the work right away. I want to pop the card/s out plug them into my computer and go over the footage with the rider.

Any suggestions as to workflow and equipment? I like Edius because it is fast and mostly realtime. I don't do much of anything to the footage except cuts/dissolves and maybe a title or two if I am sending the video to a prospective purchaser.

I started out with a NewTek Toaster in 1989. Then the Flyer. I paid 7,500 US dollars for two 9GB hard drives at the time. It always amazes me now about storage. My first hard drive was a Data Gerneral 16 MB , with 8 MB fixed and 8 MB removable disc bigger than a record album. It was the size of a dishwasher.
And Slow but I was in heaven coming from 8 inch floppies!

Go for HPX171 in that case. P2 card - no need to transcode to Canopus HQ to start editing.

In the absence of a specialised SSE instruction to decode AVCHD files, you will need an equivalent of roughly 6 - 7 Ghz processor to decode AVCHD files in realtime using standard i86 instructions. No such thing in the world today. Multi-cores don't cut this one ... one core is still running at 3.2GHz only (or whatever the processor speed is). I have grave doubts i7 processor will run fast enough for that purpose either.

I guess I will have to bite the bullet on the expense of the P2 cards. That is as I see it the only drawback to the HPX171
