  • 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 :)

This is very strange. It's a three frame loop (which suggests a codec issue) and then each frame is out of alignment (which suggests a codec error) but it's the exposure that gets me. Each frame looks as though it was recorded at a different interval (suggesting time lapse). Also, each frame in the three frame loop is exposed at a different T-Stop.

I'd like to see the meta data of this file.
I'd like to see at least one other shot from the day, from the other camera.
I'd like to know the project settings, the exposure, and whether this was shot at 2K or 4K.

I think these details could help.

I went back and took a closer look at the footage and I am beginning to believe that there is more to this than the cold weather. As battistella pointed out "it's a three frame loop " and possibly at interval recording.

Would you mind shearing what and how you were trying to shoot?

If you PM me I can point you to a place you can post the R3D file so more people can have a closer look.

The QT is not as helpful. It looks like the file is a 2K and quite short so it should upload fairly quickly.

Once it's up I can point people toward it.

Let me know if you want to do this, more minds on it might solve it quickly.

It's this exact reason why I try to keep off this forum. This is not a hoax, and did really happen. Personally I don't care what you think, I know the issues I've been having. If your not interested in hearing this, then I'l revert back to doing these tests and my work in private, and only disclosing to RED. No wonder people steer clear.

It seems like if you don't get responses in 5min you "challenge credibility". I have a life and work outside this camera, and I don't live on this board.

As for some of the other reasonable questions members posted

The batteries were in the case in the cold, and they worked fine, with good life.

When I got the camera back to the suite and shot inside, I had no problems with that footage on either camera.

good luck guys, I'm out of here.

Colin,

I offer you a whole hearted genuine apology. You are completely correct and I jumped the gun in calling this a hoax. I do not wish to question your credibility at all (which is why I stated that).

I wish I could help and wanted to help. The thread just kind of died all of a sudden and I was not sure why?

Please accept my apology and please keep posting.

Well Im glad that we got the discussion going on this issue.
As many have mentioned- we are still waiting for some kind of acknowledgment from RED. I know that this issue may nor have been worked out- which is understandable. However, maybe just a 'we're working on it' or 'it's not on top of the list' would be nice.
 
I talked with Jarred (fellow Canadian from Edmonton) who said this is some of the first footage shot in these conditions. His recommendation is that the camera be put into a Porta Brace, or other similiar system, with hot pockets if it gets really cold. I'll give this a try in the coming weeks, and see what happens.

The footage that was not corrupt looked great, I shot a kite skier playing around a bit in the snow. I have an editor cutting it together to some music, and will post it.

Please keep your creative comments to yourself, as this was primarily a test to see how this performed in the cold. The 20mm-120mm super 16mm lens I had on it was from the local filmpool, and has an artifact in the bottom right corner...I know about this, the lens was a freebie, I didn't complain, so please don't complain.
 
Thanks man..

I still don't like that solution for cold weather and hope Red offers us a little more hope.. What if you're on a 10 day trek and space is limited and you can't carry all those hot packs.... that's what worries me.

High/low temperature seems like its the Red's achilles heal

As with most things RED, I'm sure it will get addressed. As for the long hikes into the woods, if you can handle all the CF cards, batteries, solar charger, etc. Some hot packs, (or some rocks in a fire) isn't so bad...
 
Thanks for putting up the clips! It certainly looks cold there. I've mirrored it at bealecorner.org/red

At the very end, it looks like you were trying a timelapse shot of the sky, is that right? I can see where, if you were near the cold limit for the camera, timelapse operation might push something over the edge.

In timelapse I assume the Redcode compression circuit is only working occasionally when you record a frame. When the circuit is not active, it's not dissipating heat, and so it gets colder. If the viewfinder/viewscreen is still live in lapse mode, then that signal path still works, because the circuits are continually on and keeping themselves warm. So when you check the viewscreen everything appears to be ok. Only later do you see the codec problem when you check the R3D file.

This is just a theory... call it the "use it or loose it (when cold)" theory.
 
I'm sure it's all about the cold, but let me go out on a limb here - could it be some form of static electricity?

Being originally from Manitoba myself, I know it's damn dry out there and static electricity has nailed me more than once. Last year I was shooting on a rubber surfaced floor with 70 foot dolly track. During these moves I had an onboard monitor and a client monitor (with a long tethered cable that dragged along the floor). Nothing looked problematic during the shoot. Footage on all monitors seemed fine, but when I brought it back to edit I lost a hell of a lot of good footage - static seemed to "zap" the image (visual and audio).

Another time shooting 35mm in the Himalayas (very dry at high altitudes), static electricity built up in the mag and intermittently flashed the frame.

Food for thought.

While it was quite cold, the humidity was good, and I didn't experiance any static discharge (touching camera, or the truck) don't know if this is the reason, but I'm not cleaver enough to say for certain...
 
Colin,

Was it while you were shooting time lapse?

It looks like you were filming near Wilcox. Is that where you were?

I'd still like to find a way to test if it's the CF media or the camera itself causing the problems in the cold. Once the camera is up and running in the cold, I would think that it could sustain itself from its own heat generation. May need to cover it, especially if it's windy though. But I'm wondering at what temperature the CF cards lose their reliability? Anyone want to put a CF card on dry ice overnight and then see if you can pull it out of the cooler and record to it before it warms up?

Colin,

Is there any indication that the problematic clips were recorded to frozen CF media perhaps? Or the good clips were shot to cards that came right out of someone's coat pocket?
 
I'm sure there is some limit beyond which the CF card fails, but it's not my first guess in this case.

It appears to me that the problem clip shows a full image in every frame, but that frame is panning sideways in a 3-frame cycle revealing new scenery at the leading edge. It doesn't seem like something that the flash card could possibly do by itself; the card can't know what the landscape looks like outside the frame.

I agree it could perhaps be just the card if he recorded a wider frame on the R3D file, and we are seeing just a smaller window into that, which was cropped out in post. But I assume that's not the case.

Hmmm... 13F? That isn't that cold. Anyway, I know it's not a direct test of RED One, but I'm picking up a RED CF card from someone tomorrow and I'll throw it in a freezer set to about -10F (about as cold as I can make it). I'll throw in a couple other cards too and let them sit overnight. I'll pull them out one and put them into my FW800 CF unit and dump R3D files to them before they thaw out. Will be interesting to see what happens. :) I've got a Kingston 266X 8GB in the freezer right now and will try that one in the morning just to see if there's any indication this could be a problem.
