Bitrate

RGAlix · October 12, 2012, 05:05:32 PM

Hi,

Magic Lantern is able to increase the bitrate of the camera. In my case, when I choose how much I want to increase it by, after 1,5x, the figures become red. What does it mean? Will it work, but with a risk? Will it refuse to work?
In doubt, I didn't try.

Can anyone clarify this for me?

Thank you.

You did well, its processor could fry due to heat.

No, it is just to remind you, since you didn't read the user manual, that recording might stop, depending on your card, audio on or off and blahblahblah.

Okay. So that means I can increase the bitrate as long as it stays white, right?
Is it really safe? I mean, ist there any chance of overheating even in the white figures?

I don't know why the overheating thing is getting many people scared. Overheating happens, if you try to record for quite a long time under the sun the camera can overheat and tell you to stop. Things get hotter when they work, just as you do when you lift a weight or do jogging. ML doesn't do any magic. There are things you should avoid doing (leave the camera ON if it's frozen or remove the card right after you've opened the card door) but apart from that it doesn't change any hardware and your camera will get as hot as it could before installing it.
Those figures are shown in a different colour just to remind you to think twice about using them if it's the first time and you're on an important shooting or recording session. You're camera won't explode or catch fire unless you want it to.

I've only had the overheat warning once on a 100deg day. The camera didn't shut off, it just put a little thermometer on the screen.

I've crashed/frozen and pushed way higher than the "red" numbers go. Camera still works. Its no delicate flower.

Ok, so I can go as high as I want, and it will just stop record or get frozen, right?
You say overheating existed before ML, but I just want to make sure that in conditions where overheating might normally happen, I won't kill my CF card by increasing too much the bitrate in addition to these conditions.

Bugs aside, the camera will shut off if it gets too hot

Thank you (I just need to be very clear with it)!

One last question: how can I know the actual bitrate when I have figures like 1.5x?

You open the file on the PC and look at the birate with tools like http://www.winhoros.de/docs/bitrate-viewer/

Ok, thank you both nanomad and ilguercio! No more question about that!

CFs don't die of "too much data".
