Hello all,

I filmed my very first shots with Magic Lantern raw video on a 5d2 a while back (2-11-14) with the latest version at the time, never edited the footage.  Now I'm trying to edit the footage and use it, but I keep running into the same issue.  When I convert everything to DNG and play back the recording, where ever there is light that is TOO bright, I get this purple/multi-color pixel stuff.  I don't know what to call it, other than dead pixels.  Its only when the light that is being picked up by the camera is TOO bright, and I don't know how to fix it.  I have google'd for a bit but haven't really found the answer.  Hoping someone can help me figure this out?

Hmm, ok thanks! I can actually preview the clips using (oh gosh, I can't remember the program now)... Here it is, a program I downloaded called MLVBrowseSharp

Anyway, that certainly  comes in handy to view the clips but i'm after making the after effects process faster.  Would switching to an NVidia card make any difference in that operation?  I know that (most) adobe products are better off with using Cuda cores than using openGL, and programs like after effects aren't ready to use openCL or make use of ATI cards just yet, so if I switched GPUs would that make a difference?

As you can see my specs aren't teensy, and trying to figure out the bottleneck is driving me crazy :-/
Do you guys also go through this delay while converting to a usable format?

Hey there forum

Ok, so I did my first test run with shooting RAW, and WOW what an awesome improvement! The video I shot was under ground, with a ligthing guy who usually provides lighting for concerts/nightclubs, so it was awesome capturing the bright brights/dark darks, and being able to have control after shooting!!

My workflow that i'm using as of now (from what I gathered over the internet) is this...

/ Import MLV (M00, M01) files from card/
(5-13 minutes)
/ Convert MLV files into DNGs /
(4-12 minutes)
/ Open After Effects CC, import sequence by clicking on first frame, grading that first frame, and hit open /
(2-4 minutes)
/// Try to skip ahead, or ram preview any of it ///
(FOREVER minutes)


I wound up reverting to just picking settings in camera raw, applying, then export to adobe media encoder, wait an hour an a half, then put each of those files in premiere, and work with the entire video that way.  But the process from actually seeing if my raw edits are good enough, to the point where I use them in final edits takes YEARS.

I would LOVE some help on this, my system is no slouch, yet it seems like it is when working with raw video!

My setup is this:
AMD 8 Core 4 ghz
16 GB ram
2 ATI Gigabyte 7970s
256 SSD
Windows 7

Been messing around with Dual_iso raws for the past week, this totally changes my shooting style! THANK YOU!!!



Just a question, cause I can't seem to find a master list anywhere, but I saw that the 5d3 has the ability to record dual_iso raw video, but I can't seem to figure out how to enable it in the 5d2.  I'm going to assume that its not doable at this time on the 5dmk2?

What about the 6d?

Also, one other quick question I had.  When exposing for a Dual ISO shot, are you guys exposing for the base ISO, or the recover ISO, or somewhere in between?

It's really doing ISO 400/1600.  You haven't specified what camera model you're using, but the available recovery ISOs are restricted depending on the particular model.  I know that my 50D tops out at ISO 1600.  The technical reason for this restriction is that Dual ISO is implemented by changing the CMOS-gain registers, while the ISOs greater than 1600 on the 50D have the same CMOS gain as ISO 1600 (a different amplifier gets you to the higher ISOs).

Ok thanks.  Yea sorry about that, I forgot.  I have a 5d mk2


Recently I decided to try this out when I was out for a party at a museum.  The dance floor was pretty much pitch black, so I decided to use a flash. I noticed during post afterward, when I load the files in Lightroom 5 and shooting people, I tend to take down the highlights, resulting in the skin gets VERY "sun-burned". More so than regular raw files (obviously, cause the highlight recovery is insanely effective now)....  Besides taking down the red/yellow/orange levels to try and compensate and recover the highlights, is there anything you guys would recommend to keep the "sun-burn" under control?

I'm loving this level of control of DR I have now, its so addicting to just shoot Dual Iso all the time!! Thank you again for this awesome tool!!

First time poster here.

I would like to start by saying a super huge THANK YOU to the Magic Lantern team, i've been hesitating to make the jump, but a spit of inspiration hit me last night and I installed ML and i'm VERY impressed!!

On the Dual ISO topic, I have a question.
Maybe i'm not doing something right, but....
In the EXPO menu, where the option for Dual ISO lay, if the camera's iso is at (lets say) 400, I want to do 3 stops up (3200) to get a good amount of low light coverage.  I enable this, but when I exit out of that menu, it still reads 400/1600. Then, if I goto the main ML menu, and go all the way to the right, it shows me everything thats modified (which is only DUAL iso) and in this menu it reads DUAL ISO 400/1600 (recovery ISO 3200) under that.

Also, I've noticed that the "Dynamic Range Gained" never goes up from 1.1EV when I change the recovery ISO from 1600 and up.

So I apologize for the noob question, but..
If i'm setting my Dual ISO at 3200 Recovery ISO,
Is it really stuck at 1600 ISO, or is it actually doing 400/3200?
