Hi,

I've searched the forums for best answer but I'm not 100% about it all.

Goal: to record clean HDMI (Mirrored mode) for one hour continuously with one Canon LP-E6. Possible?

I've enabled the power saving features but it seems that if I select the turn LCD off during idle, it also shuts the sensor down and cuts off HDMI. Is there a way to disable LCD completely (not just dim) during idle, and still keep HDMI stream going? I read something about motion detecting, does that not eat up battery as well?

Thanks,
PJ

Excellent, thank you Alex & dmilligan, very helpful!

For recording HDMI to ProRes, would the same principle apply? Or does the ML digital ISO not affect HDMI (I assume it does)?

Right, I've tried searching the forums having no luck.

Having read this thread, my understanding on ETTR is that it really shines when recording RAW (highlight recovery etc.) but if the sensor is linear and most colour information is captured at the bright end of the sensor, surely ETTR should be used with H.264 recording as well? Or am I missing something here?

I saw someone commenting that editing H.264 in post is destructive, which of course is the case, but wouldn't using ETTR still produce better results than 'correct' exposure (providing no clipping, or acceptable clipping occurs)? Wouldn't this yield better SN ratio and thus less noise in the shadows for the H.264 too?

And on another note, should ETTR be used if recording to higher bitrate codec (i.e. ProRes 422 HQ) through HDMI?

I mostly shoot video in very controlled environment so knowing this would be helpful.

Thanks,
PJ

Guys I really really need your help. I must be missing some vital step but I've been over the instal procedure at least a dozen times and my camera just won't read the files. her's what I've done. Format card, download ML files 1.2.3  Put files on card. Put card in camera. switched on camera. Then nothing. Went to firmware up date. pressed firmware update. camera says you'll need a memory card to update I press Ok then nothing. 12 times I've done this and still nothing. What should the ML files look like? I've gone to the link on this page and copied those files which says ML nightly. Are these ally he files I need cause sit doesn't look like it to me. Need your help. Some guy tried to charge me £120 for the privilege of installing Magic Lantern and I'm getting rather frazzled.

Sounds like you have an issue which isn't directly related to ML & FW 1.2.3. but potentially something wrong with the camera and/or card if the camera doesn't recognise your card.

Could it be that you have the wrong card slot selected (CF/SD) in Canon menus? Can someone tell if this actually is possible or does the camera check both slots for cards/firmware?

Sorry, looking for some clarity on the FPS override and CF/SD card issue:

Alex, are you saying that the ~40fps recording (MLV & H.264) gives less corrupted frames if using SD card? Like someone mentioned, are there any SD card that are even fast enough for MLV recording at 40fps? Am I misunderstanding something here?
