The quick answer Tom is that it can’t. whenever you’re considering a transfer of data between local devices on a computer, or multiple computers on a network, the speed of that transfer will be limited by the slowest connection in the chain. I suppose a “weakest link in the chain” metaphor could be used here.
SATA, depending on the flavor you’re using has a theoretical maximum speed of 1500, 3000 or 6000Mbps. Those translate into 187.5, 375 and 750 MBps. As long as you’re using a SATA interface, you will never achieve read or write speeds above those thresholds, regardless of whether or not you have a device in the transfer chain hooked up using Thunderbolt.
Of course, with that said, you’ll never achieve anything near those thresholds either, because those are theoretical maximums which disregard other factors like hard drive speed and bus communication over head etc…
I hope that helps

Also Henry, you can use the “Open Image Sequence” in Quicktime 7 Pro to import a group of still images and Quicktime will allow you to specify how long each image should appear in the timeline. When you click OK, Quicktime builds a movie with your specified settings.
Once you do that, you can export your movie out and bring it into Final Cut for editing.
It doesn’t solve your preferences issue I realize, but it is another way to skin this cat!

Hi Andy,
The problem with using Handbrake is that you’re introducing two more generations of compression to you material. Every time you re-encode the video, you introduce compression artifacts which can’t be removed. Those artifacts get worse with every generation of encoding.
You can use the Disk Utility to create an image from your source DVD that you can then use to create copies.
To do this, put the DVD into your Mac and open Disk Utility. The DVD should show up in the left window. Select it and press the “New Image” button in the toolbar. From there, select “DVD/CD Master from the drop down “Image Format:” menu. Name your new image and save it somewhere with enough free space to create the image. Once Disk Utility has created the image, it should show up in the bottom half of the left window, just insert a blank DVD, select your new image and hit burn.
Also, when ever I’m burning DVDs, I like to select the slowest speed available. Most Macs will let you do 8x burn speeds, but these disc are much more prone to read errors when playing back, especially if someone is using an older DVD player. I have never had issues when burning at 1x.
Hope that helps!

Rick,
Have you tried VLC Media Player? In my experience, that media player will play most anything you throw at it. I’m absolutely certain that it will handle .mp4 files, I play them back on VLC all the time.You can find the installer at videolan.org And it’s free!
If VLC won’t play those files, then I would imagine they’ve become corrupted somewhere in the transfer process.
Good Luck!

Hi Takashi,
I’m not sure if this is a file permission issue or not, but a good way to test this would be to attempt to copy the files as the super user. Are you familiar with the “sudo” command in the terminal?
you would want to do something like:
“sudo cp /source/folder /destination/folder”
the nice thing is using the finder, you can drag and drop folders onto the Terminal window to copy their path directly into the command.
it will then ask you for you password, and hopefully after that everything will copy over.
It’s worth a shot!
Good luck

Hi RJ,
Do all three drives show up in the “Disk Utility” application?
I’m not sure if this is happening because both Volumes are labeled “Macintosh HD” but you can test this by renaming the Volume in question.
You’re going to have to get into the terminal for this, which if you haven’t done before can be a bit daunting at first, but we’re only going to be using a few commands. The Terminal is located in your
“/Applications/Utilities” folder.open up the Terminal and type “diskutil list” This will print out a list of all of the hard disks installed on your computer, and all of the Volumes that those disks have been partitioned into. All you need to do is find the disk that’s not showing up in the Finder and figure out what it’s Linux-based volume identifier is (This will look something like “/dev/disk0s1”)
Here’s what my Mac shows:
*******************
Once you determine which volume is not showing up, you can rename it using the following command
“diskutil rename /dev/disk0s1 NewName”
Again, from my computer:
just make sure to replace the “/dev/disk0s1” with the actual identifier of your volume. And notice that if you want to have a space in the name, you need to escape it with a “”
try changing the name and see if it gets you anywhere.
Also, in the Finder Menu, under Preferences (Keyboard shortcut “Command+,”) you can tell the finder you want it to display your hard drives on the desktop.
Good Luck!

I’ll be the first to admit that I don’t necessarily qualify as an “Audio Professional” …more of an “Audio I Know Enough to be Dangerous.” But Martin you said you’re planning on moving around with your camera quite a bit to pick up your shots. It might be best to plan on recording your audio to an external recorder that you could then sync up with your video in post.
The connections would be similar, but you’d have the freedom to move your camera around untethered. Just make sure to clap your hands on camera at the start of every take so you have a reference you can use to sync the audio and the video.
Just a suggestion, good luck!

Hi Ricky,
Unfortunately, the best way to go about this using only the built-in tools in Mac OS X is to create a password protected disk image using the disk utility and then place the files inside of it.
You could change the permissions on the folder so that you were the only user who had read/write/execute access. This would prevent other users on the computer from being able to see or modify any of those files, however, if someone were to use your computer while logged in as you, they would be able to do whatever they wanted. So, it’s a second option, but isn’t nearly as secure.
Also, consider the fact that, depending on the kind of file you’re modifying, changing the permission settings may have unintended consequences. It sounds like you’re just trying to lock down some personal word documents or spreadsheets or something like that, but if you start changing the permission settings on application or system files, you may break a program, or your entire OS if you’re not careful.
There are third party options available for this kind of task, but ultimately, I would revisit the disk image idea.

Hi Mendy,
If you have the operating system install disc for the MBP handy, you can insert that into the computer, double click the icon once it pops up and the computer will restart and boot from the Install CD.If you proceed to (I think, don’t remember if you can do this right off the bat.) the second window of the install process, you won’t start installing the OS, but you will get the option to select from a Utilities Menu at the top of the screen. Inside that Utilities Menu is an option to reset the administrator password.
Good luck!

Hey Josh,
I’m wondering what kind of shotgun microphone you’re using to test this setup?
I don’t believe that the audio inputs on that mixer provide phantom power, so if you’re using a condenser style microphone, that would explain the silence.I’m also willing to bet that the phantom power on your camera is on, which is why it works no problem when you put the camera back in the signal path.
You’re definitely on the right path with flipping the audio input setup to ANALOG. If you have a dynamic microphone available, like a Shure SM-58, try plugging that into the HMX with the input set to analog and see if it’s any different.
Good Luck!
