  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Moving On...

can you expand ???

can you expand ???

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 ???

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?

And the RED Flash drive (which is a SSD raid instead), expensive though.

I'm afraid it is the nature of hard drive and RAID technology - not Red Drives in particular. Any camera needing to record that kind of bandwidth and using a hard drive drive like that will have the same problem. If vibration resistance is needed then it would have to move to a RAID 1+0 that would more than double the cost and complexity even if it could economically be made to handle the write bandwidth- which is why Red added the Red Flash Drive and the Red CF Module to their media line up.

The reason that some hard drive solutions at lower range camera systems may be more robust is because they are using a single drive, or better yet a RAID 1, that is all you need for the lower bandwidth.

And I gotta say that after having my camera for two months of shooting with the Red Drive from shoulder to dolly to cradled in my arms and braced against the door of a moving car... I have not had a single dropped frame.

Not one.

Of course, your mileage may have varied in due to the thumping bass line running through it and that will have me keeping an eye on this for future shoots.

That is if it wasn't just a matter of the battery plate not letting the Red Brick seat fully without a good push.
 
I guess us film guys are spoiled. We have always worked with 4 minute mags and anything else seems like overkill. The fact that an 8GB compactflash card runs for 4 minutes on Red makes it more like film than anything else.

I can picture using the drive for long (tripod) interviews in a documentary-type situation. Other than that, 4 minutes is about the length of my attention span anyway.
