Ted,
You might want to read up on the different RAID strategies even if you don’t use AppleRAID.
The command you issued did exactly what you told it to do. You asked for a RAID 1 mirror across 4 drives and that’s what it created. When you have drives of different sizes, the usable capacity of each drive in the the RAID will default to the size of smallest drive. So a 3TB + 2TB drive can never be more than a 2TB + 2TB drive because every drive must be the same size and since you can’t format a 2TB for 3TB but you can format a 3TB drive for 2TB, that’s what happens. So that command made a mirror (meaning every drive has the exact same data) with 4 x 2TB drives which yields 2TB of capacity copied 4 times (mirrored)!
Now I realize that’s not what you wanted. From the sound of your description, I believe that what you wanted was a RAID 0 which adds the drive capacities together but even then, it can only add drives of the same size so your 3TB drive gets treated like a 2TB drive and you would get an 8TB array (2TB+2TB+2TB+2TB) in a RAID 0 stripe. The command for that is:
diskutil appleRAID create stripe Backup JHFS+ disk5s2 disk6s2 disk7s2 disk8s2
Personally I would never make a RAID 0 with 4 disks because it one fails you loose the whole thing. With 4 disks you really want a RAID 5 but you will lose the capacity of one disk for parity so that the array can be rebuilt if a drive fails. That would make a 6TB RAID 5 from 4 x 2TB disks.
So even if you buy SoftRaid, I would be very careful to understand the implications of creating a 4 disk RAID 0. It will be crazy fast, but if one drive fails… all will be lost!

[Joshua Jackson] “In the audio world, I would put a limiter on the track and say “don’t go past this threshold”.
Is there something like that, in the video world?”Yes, there is. Place the Broadcast Colors filter on the Master Video Bus (above the Preview Window) or even on a Track if you want, and it will clamp down the video to broadcast legal limits much like a Brick Wall Limiter. There are several presets for different broadcast standards.

[Seb Mackintosh] “When I first rendered (Apple iPad 720p), it came up crisp but the motion looks stuttery. Even on a monitor set to 50 refresh rate. You can see something like ghosts.”
By default, the Apple iPad 720p setting is 29.970 (NTSC) fps which would explain why your PAL 25 fps video had ghosting. Try changing the frame rate to 25.000.

[Richard Jones] “I wonder if either of you can comment please.”
Gary Rebholz of MAGIX has “officially” stated that scripts WILL need to be MODIFIED to work with Vegas Pro 14.0.
Just to be very clear: Existing scripts WILL NOT continue to work!
We don’t know if the extent of the change is simply a namespace change from Sony.Vegas to something else, or if it goes deeper into removing com.sonycreativesoftware from all of the OFX plug-in presets or the word “Sony” from all of the FX names (e.g., “Sony Chroma Key, Sony Levels”, etc.) but changes will need to be made to scripts and command extensions by their authors and if the authors have abandoned the script then it may never work with Vegas Pro 14.

[Noah Kadner] “HDV comes over Firewire as a digital signal with no transcoding during capture So…. any deck will give you identical quality captures as long as the heads are in decent shape.”

We use the term “capture” but HDV is really a digital transfer just like DV. Whatever digital bits are on the tape are the exact same bits in the file on your hard drive. So quality is not a deciding factor. It’s all about features from deck to deck.
I should probably point out that HDV is NOT a standard that everyone followed i.e., Panasonic, and Canon HDV tapes might not play back on a Sony deck! (it’s not like DV at all in that respect) and the 24p formats were absolutely incompatible. Every manufacturer had their own crazy scheme of stuffing 24p in a 60i stream. I would spend time investigating which tape formats those decks will play back or you might get surprised after purchasing one when it doesn’t read your tapes.

[Amanda Duffield] “So basically VEgas and/or Caption Assistant have what I want except for the burning in bit. “
Caption Assistant is an aid for creating Closed Caption Markers in Vegas Pro. It currently relies on Vegas Pro to do all of the rendering. We could add the ability to burn in captions in the future but it currently doesn’t do that today.

[Nigel O'Neill] “If you have a choice of export formats, I would use .MXF”
+1
Sony MXF works great with Vegas Pro.
If you need to edit QuickTime MOV files, your other option is to buy a Mac. I’m dead serious. It’s a matter of using the right tool for the job and if you have a camera that produces QuickTime files, you should be editing with a Mac and Final Cut Pro X. Otherwise buy a Sony camera that shoots MXF files. Like I said, it’s a matter of matching up the right tools to work together.

Make sure that your project setting and render settings match (i.e., both 1080, or both 720, etc.), and that you set the preview to Best (Full) when placing anything with Track Motion. If those two things are true, the render should look identical to your Best (Full) Preview.

[Ron Whitaker] “Is Boris a plugin for Vegas?”
Yes, Boris RED can operate as a plug-in or stand-alone. The projects you save in stand-alone mode can be loaded into the plug-in version as well. So imagine having AE as a plug-in… that is what Boris RED gives you.
