Magic Lantern enables 14-bit RAW CinemaDNG on 5D

SO what now the CF card is gonna spontaneously combust?

People have reported both the camera and the CF card as getting far warmer than usual. Unless this is incorrect, then it would be folly to act like nothing could potentially happen.

Unless you engineer cameras for a living, then you cannot say for certain that your camera will be okay.

Thats not to say that there will not be any overheating issues with RAW recording on a canon and there is a chance of permanently damaging your DIGIC processor, Its just you are not going to wear out your components "within the chain"

I do electronic repair so I do have quite a bit of experience with this. The only thing that comes close to the issues that you are talking about are power amplifiers.

Thanks for correcting me on what it's called, actually didn't know the right term.

So there's no way at all that the components dealing with the CF card communication could get any warmer or overheat? Not just the DIGIC, but the CF hardware on camera side? I thought so, but of course I am definitely not doing that kind of work for a living so someone with more experience ought to chime in.

That was the only place I thought you might find trouble, not at the DIGIC but if you're saying there as well then okay.
 
Lets consider what we do know: Cards generate heat. Digic generates heat encoding H.264. Theoretically it will all just even out. ML have been very weary of heat for ages, there's even a digic temp gauge in ML. They know what they're doing.

I do sincerely believe that heat will not be an issue, just wouldn't be surprised that's all I meant, and that's why people are being wary of it or are bringing it up everywhere.

Are Komputer Bay cards working now? Lexar 1000X just arrived today, had to actually spend my time delivering screeners and script meeting... had no time to play with the camera(s).
 
Well it is a DSLR so sure heat is an issue but swapping 2 bodies around fixes that problem.

Komp bay card has been dropping frames, so has transcend, they're a bit too slow for 1080p, but they work on todays build up to 900 I think.

I've been screwing around all morning try to creat a canon standard sLUT for adobe camera raw... still haven't nailed it.

lexar is solid, I got a Toshiba 1066x coming.
 
The point about heat and any possible longer term effects is that no one will know until cameras are out there for a while. Period. Glad people are happy with the hack, it's awesome...but to just off hand dismiss any POSSIBLE effects on a camera being enabled to do something it was never made to do is just as ridiculous sounding as someone saying this WILL fry the camera. Yeah, the feed has been there, but they have changed the way it is running, the data rate, the features the processor is being fed.

That post is bs (devs agree). The constant raw has always been running on the Canon firmware, it's a liveview feed, ML just tapped the feed and without H.264 encoding it should actually run cooler!

Seriously you guys sound like a bunch of old women.

I was reporting it. I did not SAY it. That was uncalled for.

They can get hot but not so hot that you will see the solder melt or damage the components. The camera would lock up way before anything like that would happen and thats if canons thermal protection didn't shut down the camera first.

The components that we are talking about should function @ about 85°C/185°F. If you did hit that temp you might get a corrupt card, for camera damage would have to be absurdly hot like 200°C/390°F your CMOS would have stopped working at 120°C. I should not have to mention that the camera would have shut down way before any of this would be possible.

Cool, thanks for taking the time out to correct me and offer some information as well. That's good to know... since I'm hacking a camera that I really can't afford. Haha

So, lexar's at 250-300 a shot to start, and likely no less until you or someone else figures out the Toshiba thing.

At least as of right now.
 
If the 4gb is because of fat32 then try formatting the cards in exFat instead........

Why the hell would Canon use an out of date file format anyways!
