 Posted: Mon Jun 09, 2008 9:31 pm Post subject: "End Program" Red Camera Music Video Shoot |
 |
|
The shoot was directed by Andrew (upper left, with glasses), shot by Alex (upper left, with camera) and assisted by Margret (centre) and me (right, pulling focus).
The band was loud and rocking, which brings us to our first lesson for anyone using a Red cam. DO NOT record to a hard drive under these conditons.
Funny thing is, if someone had left a hard drive sitting on one of the speakers, I probably would have said that's a bad idea due to the amount of vibration coming from it. Hard drives don't like being shaken when they're trying to write data. But it never crossed my mind that the sound waves in the air are just as bad if loud enough. And it was plenty loud!!
So loud in fact that it cause errors on the hard drive. Good news is that it didn't damage the drive, but a large percentage of the footage was corrupt. The drive would record a few seconds of footage and then not record for a few seconds.
The camera has the option of recording to compact flash cards; a solid state medium with no moving parts, so it isn't susceptible to vibrations. Ironically, we had the gear to do it that way. CF cards only hold 8 gigs, so we had a system where were we would rotate through three cards. While one was in the camera the other would be downloaded to an external drive hooked up to a laptop. The third was there in case we ever got caught short.
Yep, we lugged the entire setup there and decided not to use it. Live and learn.
Anyway... there will be more updates later as we figure out exactly what our editing work flow is going to be using this bleeding edge technology. |

|

The corrupt frames have been causing us some grief. They cause Quicktime and Final Cut to crash.
One solution is to convert all the footage through Red Cine. It doesn't crash when it hits a corrupt frame, but it does abort the process, so it would have to be baby sat, picking up all the breaks manually. No a big deal if you only have a bit of corruption, but we have a lot.
Now we're trying to use the Iridas system to lay the footage off to HD. Looks like it's going to work; the corrupt frames don't seem to bother it. But this is a solution that requires tens of thousands of dollars of equipment. Luckily we have access to it at work, but this is not a solution most people could afford. And it takes us out of the tapeless work flow we were hoping for. Sure we could just digitize the footage back into Final Cut, but the requires a system capable of HD I/O and we're forced to abandon the very compact R3D file format that the Red cam uses.
Again, we have access to this kind of equipment at work, but we couldn't afford this ourselves.
More updates to come... |

|

The Iridas did a good job of getting the Red footage onto HD-Cam SR.
However, this was not the original plan, so it's kind of thrown a spanner into the gears of what we were originally attempting.
The plan was to use the Red Quicktime proxies in Final Cut and perhaps mix in some of the GL1 standard def footage as well. A pull list (using Crimson) then would be used to process just what footage is needed through Red Cine and up convert any GL1 footage to HD in the Final Cut timeline.
While a solution to the corrupt Red footage was being explored, Andrew put together an edit using only GL1 footage.
Since there was more than enough good footage from the GL1 to complete the project without the Red footage, it was decided that there was no point in pursuing an HD finish. The Red footage was down converted to mini-DV and edited along side the GL1 footage in Vegas Video.
It's too bad things didn't work out. But this was meant to be a learning experience and we certainly learned something. |
