Downloading 5k footage times
on Jul 9, 2015 at 11:45:32 pm


I'm on a film. And they shot scenes that are 10 minutes long. At the end of the day I have 5 cards to download after downloading almost 12 during the day. They are shooting Red Dragon 5k 4:1 footage.

I'm using my 2.3 Ghz Intel Core i7 Macbook with 16gb ram for downloading.

This is my workflow:
-I put the card on a usb3 redmag 1.8
-Using ShotputPro5 I download the cards to two thunderbolt hard drives.
-This downloads and verifies.

A 224GB download takes about an hour.
A 164GB download takes about 40-45 minutes.

Is this how it is? My producer is breathing down my neck about this. After first card is out in the morning there is no idle time between downloads.

Those speeds are about right, it is the mini mag reader right? The larger reader is usb 2 ...

You can tell the producers it will be a lot faster with no verify, but its on them if thats what they want.

Yes it could be faster, I am able to transfer RED mags at about twice that fast.

[Mónica Calderón] "I download the cards to two thunderbolt hard drives."

Not all TB drive are created equally.

I have seen TB enclosures that do 120MBps and some that can 1200MBps from the same company.

Match the drive speed to the speed of your record media, for the fastest transfers use drives that are faster than the camera media.

Secondly I use the CRC32 or XX-Hash over MD5 for the checksum during transfers, that alone seems to trim 10-15% off the transfer times.
