Do you mean  a DVD? Or do you mean just copying the video file

I guess if I explain exactly what we're doing here with the  
creation of a disk image it may help. We need to quickly make disk  
images of some 8GB SDHC camera cards to be able to keep 8 cameras  
running continuously shooting training videos for a large retailer  
to be used as origination DVD's for their employees.


These images are then mounted on the desk top to be used in FCE to  
compile the finished DVD.. We get 30 mins of shooting on a card,  a  
G4 1.25 Mac with a USB 2.0 port and a 2.0 SD card reader it takes  
45 mins using "Disk Utility" or "Toast 8" to make the image so that  
we can then put that card back in service at that point. So we have  
a camera down for more than 15 mins. In contrast a TiBook 1 GHz  
with a 2.0 USB card using a SD card reader takes 1:45 mins to make  
the same image. An iMac i5 Quad does the job in 14 mins but we need  
to use a laptop on site due to the lugging factor.


I need a way to make the image faster, 8GB's even 14 mins seems  
excessive?? I have a MacBook Pro that I just got a CalDigit Express  
34 USB 3.0 card for that I haven't had a chance to test yet. I also  
bought a LEXAR 3.0 SD card reader. I need to know if I'm on the  
right track or spinning my wheels.


Do you need the Disk images immediately? Or are you just trying to  
get the info off the cards to put the cards back into use?


We need to get the cards back in use and he wants to be sure he has an  
image before he wipes it.


Making a disk image does involve the processor and the rest of the  
system (from the ti book vs iMac speeds).


How about just doing a straight copy of the SDHC card into a folder,  
then making the image or importing the video later into FCP?


We find it's no faster than making the image at the same time. We have  
been able to get a 12 min image on a "MBP 2.4" with a Express 34 USB  
3.0 LEXAR reader with the Transcend 8GB class 4 card.


If this is for a large retailer, wouldn't the budget allow for a few  
more cards? Dealnews is showing class 10 cards at $10 for 8GB, $18  
for 16GB and $32 for 32GB cards.


It seems my kids camera will not recognize a class 10 card. It's a  
flaw in a Cannon camera according to him. The cost is not a factor  
here except we sure don't want to buy a new camera this week:-)

Then don't bother getting DVD's involved. Get some big ol' FW drives  (or some 
big internal drives) and copy the video files from the card to the HDD and 
leave it there. If you want backups to DVD do it later.

This puts the bottleneck at reading the SDHD card,  This 
 along with a SATA card and eSATA connector and 
cable (or just thread a SATA cable through a slot in the back and be done with 
it 

With the SATA card, there's no downside to tossing in a couple terabytes of 
drives to copy the stuff to, as well.

If it's the latter, copying the file from the SDHC card to disk,  
then to DVD via either toast or Disk utility would work, no more  
ram won't help.

Just want to get an image off the SD card so we can use it again We  
have to run 8 cameras at one time and need to swap cards fast.

If it's the latter, copying the file from the SDHC card to disk, then to DVD 
via either toast or Disk utility would work, no more ram won't help.

If you mean authoring a DVD from the file on the SDHC card, well that is not 
likely to be fast under any circumstances, since it'll involve transcoding the 
video to DVD format.  I think Toast offers some rudimentary features for that 
purpose, otherwise I'd use iDVD or Sizzle, if you can find a copy.

Disk image from SD card

[John Carmonne]

What's the fastest method to create a 8GB video image from an SDHC  
card from a video camera using a G4 1.25 machine? Toast or disk  
Utility? Does processor speed matter? Does max ram help? What  
adaptors work best?
