  • 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 :)

The highest altitude for Red One?

Hola,

Generally the crew behind the camera suffers more quickly to problems than the film equipment :-)
That's my experience after shooting 6 months on Mount Everest (S-16)

Used a Panasonic AG-HVX 200 with P2 cards on 35 000 feet ( 10 688 meters ) for some high altitude parachute tests.
Not a single problem with the camera.

Yes, we had supplementary oxygen.

Good luck

Wescam+RED=Yes!

The spinning drives in REDraid are rated to 10,000 ft so we recommend using CF.

That would have been nice to know when I bought them. :bleh: My RED drives have spend most of their operational time between 8000 and 11000 feet. No problems... yet.

The REDram drives are very close. They're coming out of beta and going into production now.

Awesome. I needs me some of those for this winter. No way am I going to trust a spinning hard drive on a moving camera in sub-zero temps.
 
OK guys, it is before 4AM here and we are getting ready for some morning timelapse (back on the "ground"). Yesterday was a little disaster when started to film on the CF cards. The gods have smiled on us and we had one of the most spectacular sunrises I have seen. The bummer was when we reviewed the timelapse almost every other frame had a major codec error... Of course by then the sunrise was long gone... This was release B16 (3.2.5) and the cards were freshly formated. We do have some nice stills from my Canon for memory thou...

We switched over to the Red Drives and we had no problems for the rest of the day. This was at 15220'... Interesting thing was that my 24" iMac worked flawlessly at this altitude, but when I connected my external Maxtor HDD it would release weird noises and refuse to mount...

I will post some stills and footage once we get back home tonight...

See Ya!

Sorry to hear about the codec errors. I guess you should send RED the log files if you have them. I had codec errors on some Lexar CF cards I bought a couple months back, turns out the cards were bad, even though they appeared to be fine the first couple times I used them.

I suppose the altitude could affect the CF cards, perhaps some air was trapped inside and putting too much pressure on the internals.
 
I have been just reviewing the footage on a Mac Pro and guess what. Many shots that were showing correct exposure on the LCD's RGB histogram now show clipped highlights. Even when we reviewed the shots on the camera it all looked great. The few I managed to look at on location on the 24" iMac also looked OK. Any ideas?
 
This is the sunrise we could have had beautiful timelapse of:

... if it wasn't for codec errors like these:

As soon as we have switched over to the Red Drive it was all fine, but the sunrise was long gone. Maybe next time... :)

I thought codec errors were the thing of the B15 and the past. Did anyone experienced this type of errors on the release B16? BTW - our cards are the RED 8GB CF cards, so branding is not the problem here...

Any clues?

So true Peter, we had to do everything lot slower then we are used to. The oxygen levels were at 60% of the normal sea level. It took us about 1 hr to drive up the mountain (I am very proud of my little Yaris that "just" made it to the top :) ) and You could feel the oxygen levels dropping down as we drew up. We got really sleepy and had to take frequent naps to "recharge"... Basically it would almost always be two of us working while the third was taking nap. Around lunch time we all crushed for half an hour. By the time we got up the clouds were coming in really fast and we had barely time to pack the dolly and the crane before we had to head down...
 
Hmmm.... I'm not accepting that it's the CF cards themselves that were at fault. Not with the perfect horizontal split in the frames.

How long did the camera have to acclimate to the environment? I know you said you would be going from base to peak pretty fast.

Have you sent the log files to RED?
 
It took us about 1 hr to drive up to the 15220' and then it was about 90 min before we recorded. After we found the codec errors on playback, we have returned to the office (on site, no heating besides of our own breath...). Took a quick test with CF again showing the same type of error. Switched to Red Drive and shot another test within a couple of minutes after the CF test - no codec errors... Exact same conditions - 2~3 min difference, camera didn't even move between the two tests...

Where do You get the log files from?
