We have a Caldigit 1.5TB and a Taurus 3TB both set to Raid 1.
The reason for doing this is so there is total redundancy of the stored P2 media.
Our Caldigit, for example, has two 750GB drives and in a normal Raid 0, this would mean that you could store up to 1.35TB of usable data storage (allowing for 10% headroom), but it is not redundant.
A Raid 1 is a mirror, meaning that one 750GB drive is mounted while the other is a complete separate drive that has exactly what the mounted drive contains. So when you transfer a P2 card to the mounted drive, another copy is made to the mirror drive at the same time.
This is different than a partition in that if a part of the drive or all of the drive becomes corrupted or damaged, you simply mount the mirror drive (either through manually changing drive pins inside the enclosure, or through software in some cases) and you have a backed up copy of all your media. With a partition, you run the risk of loosing all the data if there is a hardware problem.
You could easily do the same by making two separate copies of the P2 media on two separate drives, but the Raid 1 way is idiot proof.
The Taurus drive we have has an eSata connection which makes editing in the field a breeze, the data rate is phenomenal allowing for multi layering of HD streams in real time.
The only drawback is that both these drives require mains power, which means that some applications in the field become limited.
It is very careless/dangerous to have only one copy of your media on drive, more so when you are travelling anywhere. I have experienced around 5 separate drive failures over the years, the 1st was fatal for all the data, the others thankfully were in Raid 1 (mirror) and raid 5 (self re build, Raid 5 can’t be used on a two disk array), so I have not suffered data loss in those instances. Never trust one drive 100%. -
Try turning it off if you are on a tripod. Stabilisers work best and predictably when there is movement in at least 2 axis’. On a tripod you only get movement in one axis most times.
One more thing.
The jerky movement you are seeing, is it when you play back in camera or through a laptop? -
Are they applying a blur filter on the resize? Some programs have a default gausian setting when re-scaling.

Neither of those cameras should power down fatally with just a flat battery. The circuitry allows for write off time upon detected voltage depletion.
Were the batteries OE or aftermarket? Some cheaper aftermarket batteries don’t communicate with the camera properly, and may lead to fatal power down. -
Is the optical stabiliser turned on?

There is no drop frame capable in PAL recordings. Even if the option is toggled it has no effect. Besides the time offset would be more like 7.8 seconds difference.

You won’t get zoom from the remote port on the camera, you’ll have to have 2 cables, one for camera settings, iris, and record / playback. The second one plugs into the remote port on the lens itself for zoom (and if servo enabled, focus). Download the manual for an HPX 3000 and you will find the info you want on page 146. The remote port is the same as on the HPX 2000. The pin designations for the lens will depend on what manufacturer (Fujinon, Canon, whatever…..)
If you can’t find the manual on line, drop your email here and I will send a screen grab of the page. -
Check out the HMC 150 and 170 from Panasonic too, the cheaper media may be of interest to you. FCP will transcode the AVC HD format to Pro Res 422 for you, which makes cutting more enjoyable.
On the Sony front, the EX series of cameras are good, but to get the best out of them you have to commit to using native EX codecs in FCP, and has been stated, the long GOP stream is an issue in comp’ing.
There are some new HDV camcorders from Sony such as the new Z5 and Z7, but you are stuck with HDV.
Ultimately you have a lot of choice now, but make a well informed decision, get hands on demo with all the cameras you like, and cut the demo footage so you are sure of your final decision. -
Have you transferred and used any media using this option?
It seems to have no supporting drivers, which if the P2 cards are natively recognised, might be a good thing. -
Yeah, but shooting sunsets get in the way of a good beer!!!
