Moving On...

[David Nardini]

The CF cards usually do just fine with movement. Vehicle, aerial, handheld, etc.

The drive, on the other hand, doesn't. Some users have come up with other drive modification solutions for it...:whistling:

what ??? not sure I get what you mean ... with all parameters being the same ... WHY would CF behave better than RED-DRIVE ??? and what modifications are you suggesting to RED DRIVE land ???

Beware Of Harmonic or Noise Distortion

spinning storage medium vs. non spinning....but i would love to hear more about the modifications

We definitely had loud music on set. Very loud in fact. I'm talking about a kick ass metal band. We actually felt that as close as we got to the drums the more problems we had..

It's entirely possible the acoustic energy of the band was rattling the hell out of the hard drives.

Harddrive can't take the bumps but CF card being non spinning storage can.

CREWFIX: 1. I believe the LCD monitor was to indicate 4k2:1 and not only 4k.
2. Camera on batteries during errors. Working with AC powered camera on day 2 didn't introduce any problems.

So have we ruled out harmonic noise distortion????

If you were in the line of fire it's possible the CF cards could fail as well - less probability, but still. Did it work when you were out of range of music ?

We were always in the range of the music so that is a hard one to answer. But in a few weeks we need to shoot the second part of the video which is all actors stuff and not much music, so we will see what happens then, as we have to use the Red again so it looks the same...

No RAID 0 drive array likes vibration. Striping the data onto two drives makes it far less fault tolerant and more likely that a write problem will crop up. That isn't a fault of Red but of the hard drive configuration that is needed to record that datarate.

If you needed takes longer than four minutes or were short CF cards, I would have suggested isolating the drive, even if it was just a t-shirt wrapped around it and taped to the cradle rather than hard mounted.

The CF dropping frames as well makes me scratch my head and look to the "battery bad / shore power good" problem and diagnose a poor connection on the battery mount as another possible cause of the troubles. Some of the cradles need a particularly forceful push to fully seat the battery for the first several mountings and that may have been what you ran into.

It is a shame that you ran into so much trouble with your first experience on the Red and I hope that you do give Red another chance - keeping the above points in mind when working with it.

Clint summed it up. Solid state vs spinning platters.

As for the modifications... It's a raid 0 box with two laptop drives inside. You can figure out the rest, not that I recommend doing anything to your drives. :innocent:

Wow... the hard drive, huh? Are there other Red hard drives available that would be more, shall we say, "shock absorbent"??? More meant for movement? Are they working on one? Anyone know?
