OK thanks Just need a little time for research Sooner

You would think class all 10 cards read and write fast. Some of them write at a max of only around 15mb/s which is not fast enough for a camera that can write raw video around 21mb/s.

To me it blows my mind thinking about how Magic Lantern has the T2i a "consumer" camera shooting raw video as opposed to the 5DIII and 50D, professional cameras that are writing raw video files faster than 80mb/s.

Thanks again ML!

FYI use a site like Bhphotovideo which will have the write speed. Be careful

My old 133x Lexar memorycard says a write speed of 30MB/s but their new 400x cards only have a write speed of 10MB/s

Any idea when Dual ISO will make it into nightly ?

keba · « **Reply #953 on:** August 27, 2013, 10:06:47 PM »

I'm follow the article here: http://www.thinkdigit.com/Digital-Cameras/Guide-to-using-Dual-ISO-Mode-on_17150.html

but the author did not provide the link to download file needed, the cr2hdr is OK i'm using the one provided by mk11174 http://www.mediafire.com/download/j93ojwx50ddv201/Raw2DNG_cr2hdr_550D_Windows.zip

but how about the stuffs for Dual ISO Video post-processing? (he said sth about avisyn and main.cmd...)

Many Thanks.

Why don't you follow the method author's thread?

Here is a video I shot out around my house testing out the raw video on the T2i, The dynamic range is awesome but the crop factor is a real pain to deal with...Hope more progress is made on the buffer situation to allow for larger resolutions, but still this mod is amazing a and really produces amazing visuals

Once I figure out how to get the dual ISO working on my T2i I'll make a video of that as well

BrotherD · « **Reply #956 on:** August 28, 2013, 06:17:50 AM »

Nice video Yomo! Can you post the specs, workflow and if you resized the image? I thought dual iso only works in photo mode with the T2i.

mk11174 - a1ex just posted a new file (I believe) "I've uploaded it to cr2hdr_exp.exe," on post 760 over on the Dual ISO post. I know this is the raw post, but since it has been brought up, I'm mentioning it again.

I know I have the ability to compile it myself, but I haven't been able to yet. When you have a moment, can you include the new file? from what I understand, it handles moire/aliasing better (which I guess is more obvious with the dual iso feature)

Yeah, I downloaded it and used it and it looks good but I use windows so I did not have to compile anything, are you saying you need a mac version?

telecastDaveRI · « **Reply #959 on:** August 28, 2013, 01:20:08 PM »

No. I just wasn't thinking

I'll just easily replace the file that I have haha sorry, late night last night. Thats good to hear that you had good results from it also!! Very exciting stuff!

Would it be easy to make a Lightroom plugin that copies dual iso cr2's to folder containing cr2hrd and other files, convert them, then re-import the resulting dng into lightroom?

Of Course!

I havent read too much on the dual iso yet for t2i, i hope its all ready for use :/

ItsMeLenny · « **Reply #962 on:** August 29, 2013, 03:22:08 PM »

If very wide angle lenses were cheaper/easier to get ones hands on; the crop factor wouldn't be so much of a problem.
Of course it changes how much depth of field one gets and what not, but television cameras usually have quite a small sensor size.

Haha should I get a micro 4/3 lens adaptor for my 550d? They have wider FOV lenses

I watched it again. Loving those desert shots! Have you tried shooting 960x540, 16x9, 23.97? I'm thinking you have and you just like the look of 1200x496? I'm inquiring because I have a music video shoot tomorrow. The plan is to use the Panasonic LA 7200 anamorphic adapter with a Cosina 28mm lens. You got me thinking about shooting it 1200x496 instead of 960x540. I will go do some test shots...

I am a HUGE fan of anamorphic aspect ratio, partly because how we are all so use to 16:9 and 16:10 because of web outlets

Testing out settings because you mentioned it
Since I've shot this video I updated my magic lantern to the latest build with dual ISO

23.976 Global Draw with histogram, waveform, crop overlay
I use to be able to only do 2.42:1 1200x496 continuously for ~510 frames

but with the latest build I am getting

23.976 Global Draw with histogram, waveform, crop overlay, card warmup 1GB
2.42:1 - 1200x496 - 489 Frames
2.39:1 - 1200x502 - 445 Frames
2.35:1 - 1200x510 - 410 Frames
2.20:1 - 1200x546 - 291 Frames

16:9 - 960x540 - Continuous

hope this helps

It do help me formulate a few more questions. Where did you find that latest build? It looks like you got more frames with the old build? Have you tested the dual iso? I thought we were "supposed" to shoot with Global Draw off What is card warmup 1gb?

Thanks again!

I'm using this build currently
http://www.mediafire.com/download/kjj8ddkkfmge8vz/ML_550D_Dual_ISO_Aug_25_2013_Update.zip
it was on the first page at the bottom of the first post

Yeah I don't get as many frames with the latest build compared to the build I was using before
I messed with dual ISO very little, so far what im getting is that because it is using every other line the resolution is cut in half..not to big of a problem on the mark 3 @ 1920x1200 but a big problem on the t2i @ 1200x496

Yeah I heard turning off global draw can really help increase recorded frames when shooting in raw but im only find the difference to be 20-30 frames at the most..id rather be able to monitor my levels and histogram while shooting than have 30 more frames...

I guess in the latest build they added some kind of card warm up feature with the raw video, not sure how much it helps if any but on start up your camera writes a file to the sd card and its supposed to increase read/write speeds for shooting raw

Maybe try the latest Nightly if it still allows Modules, I have not checked myself since I compile my own. But if it does, try the latest Nightly and just add the Dual Iso module to it to see if it will still work.

The build in that Dual ISO zip is not up to date just the Dual ISO is, but I don't think much has been done to RAW since the build I sent along with the Dual ISO module, but you can try.

telecastDaveRI · « **Reply #969 on:** August 30, 2013, 06:19:16 PM »

Gentlemen,

Can I ask what the settings you guys are using for the Dual ISO for RAW are. I did a couple tests yesterday.
Dragged them to the raw2dng and then cr2hdr application afterwards, and it mentioned in the DOS window that the images were not interlaced. And then when reviewing the footage, nothing appeared to be anything out of the ordinary from shooting "normal" raw video.

I tried at ISO 400 and the dual ISO set at 3200. Am I missing a setting? I review the post by a1ex and I believe I am doing everything correctly.

Thoughts? Suggestions? Insults?

There's no doubt which one looks the best

RAW is so much sharper and natural looking, also having the ability to edit it in Camera RAW is just unbelievable and it upscales nicely.

I downloaded the version I had (June 26th) The Version released with Dual ISO (Aug 8th) and the latest nightly as of today (Aug 21st) did a full exFat format and shot the same scene with the same settings and had all build get the around the exact same frames

The only difference I saw the Aug 8th build and the Aug 21st build was they removed the 1200 resolution...I remember reading it was removed because there were certain intervals of resolution that had better write speeds? still though I was quite happy rockin that 1200..guess I'll shoot a different resolution now...

Any one successfully shots dual iso video and then post processing OK? mine case after download mk11174 cr2hdr and raw2dng file, dual iso raw video file still interlaced after using raw2dng (drag and drop method)

any methods that work for our beloved 550D? (i'm try to use alex method: using his raw2dng first and then cr2hdr but bad result in the end)
