Has anyone else noticed the histogram updates slow in 60p or is it just me?

I'm very excited as I bought the T4i without thinking that ML hadn't been ported yet. I'll surely be donating once I can.

Also, noob question: where exactly can I download these Betas?

I am going to present you with the answer to every noob question ever asked. READ. Read this whole post or at least the last 15 pages or so and you shall see the light. Congrats on getting a new T4i BTW and welcome to the forums.

Today I was out testing ML and really enjoy how fast I can set my exposure with the histogram and decided to try out HDR video again which worked great. I noticed that the histogram updates very slow when set to 60p. Is this normal or a possible bug? This was with HDR turned off BTW.

So my GlobalDraw isn't turning on...is that an issue in the prealpha or is that just me?

wait, I'm an idiot.  it's a movie only feature.

with that said, with it on, none of the other options are working.  no zebras, no focus peaking.  it's not drawing anything on the screen.

are these features just not implemented?  There's so many pages of arguing about nothing in this thread, I think I'm missing the important posts.

It's just you. All of those features are working. Maybe you should re-download the ALpha2 and try again. You do know you have to hit the info buttons a few times to display the ML overlay right?

Will HDR photo be available in the beta? Really wanna check that out.

To anyone who is willing to help this newcomer,

I carefully followed the instructions generously given by the following two members:

... and after running EOScard, getting the 'success' message, and re-inserting my SD card, my camera does not boot. Nothing. Black screen. No light telling my the card is being accessed. Just nothing. This has me pretty nervous, of course. I'm running Windows 7, if this matters.

Can anyone PLEASE help?

You do have the battery in and charged right?

Personally I use waveform, zebras set at Y 255 and histogram.

Zebras tell us whats happening with luma but not whether we're clipping color in R, G or B channels when converted back to RGB for display and CC.

The histogram suggests when we're clipping those RGB channels, it is possible to have zebras under Y 255 and still clip a color RGB channel.

Waveform I use as much for where dark shadows are forming in the 8bit levels range in scenes of high contrast where even clipping highs shadows crush.

You sound like you really know what you are doing with exposure. I never thought about clipping colors, i'm a new DSLR user and found your post very helpful. Plan on using the histogram as well as zebras and waveform. Perfect day to go out and see if I can improve my overall video using these tips. Thank you.

The way I shoot on ANY PS is use zebras and just make sure that anything important (ie. people) doesn't have any clipping and you should be food to go. I basicallyset up my shot so the zebras show clipping in the highlights and then dial it back so I am about 1 of two stops. As soon as those zebras dissapear I know I'm good to go. Of course if say you are shooting indoors with only available light and it's sunny outside then yeah, your windows are probably gonna be blown out but unless there is anything important to your shot outside then allow it and just makes sure your subjects are correctly exposed (unless you have time to set up some lights or have a few rolls of ND)

I use zebras too but don't worry too much about blown out things such as window light or a lightbulb  but have been trying to get in the habit of using the waveform monitor as suggested in a few videos I have seen but maybe one or the other is good enough and zebras are a lot easier to see than looking at the waveform. Thanks!

I think the general premise is ETTR, expose to the right, so you expose for the highlights. Personally I'd not like the idea of a PS lifting highlights better to compress them slightly and roll them off.

Lifting shadows is to reduce loss in compression, throwing too much of the data in the low levels away.

ETTR meaning overexpose? I have been using a standard PS lately and get the highlights just barely touching the right side of the waveform monitor. Should I let the highlights go a little over using a flat PS?

Expo is hard to set when using marvells, for me at least. So with this option I expo in neutral and then have lifted shadows when I start recording.

I don't know if its more right or wrong.

Lifted shadows doesn't sound bad since you are going to CC anyways with a "flat" style anyways. I guess my question was kind of stupid now that I read your response. I guess it depends on the specific style used and as long as the highlights aren't lifted I guess you could expose and focus with a standard style and record with a "flat" style. You mentioned lifted shadows, any change in highlights?

I tested the HDR video feature and even though I didn't look into it much I was able to use it. I had no problems recording or processing.

Is it really that hard to search?

He contributed so maybe he felt he shouldn't have to read?

Aborgh - Do you have files to 650D?  If you have got, could you send me?

I posted the links in a previous post and found all the links here in this thread.

"-Download the .fir file from https://bitbucket.org/hudson/magic-lantern/src/99bd629f7c5712346369840e64c04fd2d4576520/platform/650D.101/devkit/650D-safe-dumper.fir?at=unified (Thanks to Lucas_W for pointing out the link, I would have uploaded the .fir myself but thought who would use firmware from some stranger)

Enable the bootflag on the SD card:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-Do a low-level format of the SD card (DO NOT SKIP THIS)
- Enable SD card bootflag using EOSCard or similar ( software to make the card bootable: http://wiki.magiclantern.fm/3rd_party_software )

Install Magic Lantern
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-- Copy over the files to the SD card ( Download ML Alpha 2 for the 650D here: http://nanomad.magiclantern.fm/650D/magiclantern-v2.3.NEXT.2013Apr30.650D.PreAlpha2.zip and unzip to the root of your SD card. You should than have a ML folder and an autoexec.bin on the root of your SD card. "

Stumbled upon this thread and noticed I also have 1.01 and got mine in January in the U.S. Runs ALpha2 fine so far.

I see that ML can have a PS for the LCD view and a separate one for recording. From what I understand it's supposed to be handy for shooting with a neutral picture style so you can focus properly with a standard style on the LCD and have the camera use your flat style for recording without having to switch back and forth. Wouldn't you need to switch to the flat PS to set exposure anyways? I read that setting exposure when looking at the LCD with a standard style than shooting with a neutral style is wrong. If that is true why would you need the option to set separate picture styles in camera and for recording if you need to switch between the standard and neutral to first set focus than set exposure?

Been testing ML and so far the only problem I have had which isn't really a problem is when you bring up the ML menu with the Canon stock overlay on the screen the exposure bar flickers on and off over the selection description at the bottom of the screen. in the ML menu. No problem if you enter ML menu with no overlay or ML overlay on screen.

Loving ML so far. Didn't really have time to really test it today but I plan on testing tomorrow. I hope I don't upset anyone but I thought i'd share howto make you camera bootable, enable the SD card bootflag and howto load ML. This assumes you know a little about virtualization or are able to look into howto load the image and get the .fir file onto the SD card on your own as I won't go into detail on that.

Instructions:

Make the camera bootable
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-Download one of the VM guest OS images. (I chose the VMware image and enabled hardware virtualization on my motherboard)
 
-start  the guest OS.
  -copy ~/magic-lantern/platform/650D.101/devkit/650D-safe-dumper.fir to the root of your SD card
   -Place the SD card in the camera navigate to the fourth wrench menu and select firmware, camera, than select ok.

OR (easy)

-Download the .fir file from https://bitbucket.org/hudson/magic-lantern/src/99bd629f7c5712346369840e64c04fd2d4576520/platform/650D.101/devkit/650D-safe-dumper.fir?at=unified (Thanks to Lucas_W for pointing out the link, I would have uploaded the .fir myself but thought who would use firmware from some stranger)

How can I enable the BootFlag on my 650D for Magic Lantern to work?

Read my post #1081

I too am unable to load ML,

I set the card to be bootable with MacBoot, but I don't know how to set the Boot Flag on as well.

Did you check "Make DSLR Bootable" ?

You sir are a saint and a scholar.

Haha thanks. Off to play and test ML now before the rain starts.

ML Alpha2 for 650D: http://nanomad.magiclantern.fm/650D/magiclantern-v2.3.NEXT.2013Apr30.650D.PreAlpha2.zip

Instructions: http://www.magiclantern.fm/forum/index.php?topic=3697.msg32446#msg32446

I'll be testing this tonight if someone can explain how to enable the bootflag. I was already planning on doing some greenscreen tests, now I have this to look forward to as well!

you need EOSCard

[Time for a second pre-alpha.]

Time for a second pre-alpha.
This one is targeted at those that already have the bootflag enabled on the camera.

http://nanomad.magiclantern.fm/650D/magiclantern-v2.3.NEXT.2013Apr30.650D.PreAlpha2.zip


Instructions:
- Do a low-level format of the SD card (DO NOT SKIP THIS)
- Enable SD card bootflag using EOSCard or similar
- Copy over the files to the SD card

Known issues:
- Full screen magic zoom is broken

Stuff I'd like to be tested:
- Card benchmark under the debug / benchmarks menu (Post a screenshot if you do)
- HDR video (check if all the frames are in sync, e.g. no half exposed frames). Do this at every possible resolution / fps combination
- Everything else

Build still has props off, so expect some bugs here and there

If you really want to make your camera bootable you can use the devkit available on the repository inside the 650D platform folder). JUST DO NOT RUN THE FIR IN MOVIE MODE, USE PHOTO MODE AND TURN THE DIAL TO M

This is awesome. Woke up to let the cat out and planned on going back to sleep but not after seeing this. I was just wondering if there are any features that are known to be buggy that maybe we should just not use for now? I really want to help test(and check it out for myself) but want to be as cautious as I can with my baby

If the fibers of the fabric are showing blur the background.

Speaking of card quality. I was on a budget when I got my card and didn't consider the card speed and quality and how it would effect my final output. Anyone know if the Sandisk Ultra 30mbps cards are any good?
