Red Drive max duration

[Jason Joseph]

Hi

another trivial/noob question

was wondering how many minutes the red drive can shoot for without cutting? at 4k of course. this is for an event coverage job.

from my calculation 1min of 4k is around 1.6g
so a 160gb red drive would hold 100mins of footage?

has anyone rolled a red continously for that long? any problems encountered? is being in sunny/ humid singapore a factor?

i realise this is more then one question but i also realise that this forum is extremely helpful :thumbsup:
thanks for all the replies in advance

I have rolled four REDs at the same time for about 2hrs and 40 mins, no problems.

That was 4K at 2:1 redcode 28, 25fps

The RED Drive is 320Gb, how much running time you get depends on fps, choise of redcode and aspect ratio.

They do warn against filling up the disk close to 100%, I don´t know how serious it is as I never went above 90%.

Good luck and happy shooting!

Don't fill the drive up all the way. We had a shoot today and many of the shots that were in the last 10-15% of the drive have a lot of grey frames in it. The camera showed codec errors at a certain point during recording. However some of the last shots that we thought were recorded fine (no warning or errors), turned out to have grey frames in them as well..

Did you shake the camera? The RedDrive is prone to dropped frames. If the footage is important to you shoot CF. I only use the drive in situations a bigger mag is meaningful, eg. helicopter. Especially in this case the vibration of the helicopter is causing tons of dropped frames. Only putting the drive into the operators pocket solves this issue.

I would never fill up a drive with more than say 40 minutes footage. Backup is vital and spreading the risk over multiple drives makes a lot of sens. This is the reason why I consider 16GB CFs for the very most situations an ideal solution: Sturdy as tape - which are the drives not - and small enough to make a backup on remote locations with a Nexto a no-brainer.

I play it safe with the drives as well, never shooting on more than a half filled drive. Swap out drives and keep shooting while the other is transferring.

I agree it's preferable not to fill the drive more than half, however we regularly shoot (4kHD & 4k 16:9) multicam live events that go for over 2 hours, and have yet to have 1 dropped frame/crash. We back up pretty quickly afterwards! Just my experience.

Thanks Hans. We were up 25 meters from the ground in a big crane. Although we've only had the crane giving us tiny shakes two times, it was not completely hanging still in the air either. The cranes was swinging us back and forth a little, so maybe even that was enough to cause this problem then. I guess we'll have to be even more careful on that one next time..
