A little heads up - I seem to recall someone having an issue with their autofocus with ML running. I was at an event this weekend, and someway through the event I was going to do some video, so I loaded up ML, shot some video, went back to shooting stills with ML still loaded.

At one point my 7D's autofocus stopped being able to focus - I was a bit concerned, checked all the usual stuff (lens on AF, changed auto focus modes and so on), but the camera wouldn't auto-focus on anything, even when the contrast should have given the AF no problems at all.

So I turned the camera off and on again to unload ML, and the auto-focus went back to being fine, lightning quick and accurate, as I'd expect.

So while this is not much of a bug report, there is a definite case of auto-focus failure shooting stills with ML loaded, for some reason. If I can I will try to play with this and check the settings of the auto-focus failed images and see if I can reproduce this or give some clues as to what might be happening...

Sure, we're all enthusiastic - that's why we are here, that's why we support the devs, and that's why we do what we can to help in the way of testing, bug reporting, feature suggestions and so on.

Enthusiasm is what made ML happen in the first place, and it's what keeps it moving forward, as long as the devs get a little respect and room to work - entitlement and impatience from the userbase doesn't really motivate these guys spending their time to do a quite difficult task...

How much is a possibility that raw video mode will be mounted in the future?
If it is a problem of hardware, is it impossible as a matter of fact?

You guys are asking questions that no-one can answer yet. The devs simply don't know until they go in and try, and see what is possible.

Currently, g3gg0 has mentioned that the 7D is tricky because of it's unique architecture. Whether this gets solved tomorrow, next month, or next year (or not at all) depends on a number of factors which are impossible to predict. All we can do is either use what we have and enjoy new stuff as and when it happens, or join the development effort if you have those skills to try and help move the project forward.

An excellent feature that can add would be able to record at 60fps at 1080p, would the best they can do.

It seems the hardware won't allow this, it's simply not powerful enough - so I'd give up on that one, nice though it would be...

Quote from: Mark0ki on April 23, 2013, 07:35:44 PMNow think a bit logically. If you cover the sensor with shutter and mirror, then what will record the movement in front of the camera?

Well, might be possible to engage mirror lock-up, flip up the mirror and get the sensor to monitor the image for motion/processing etc, without the whole live-view/screen thing on - it's the screen which sucks up a lot of power...

Still enjoying Alpha2 here, and doing fun things with it. It's becoming too useful to ever not have it loaded... ;)

Thanks g3ggo and team ML...

Chris - read the ML docs on the website and you'll see what features are available for photography in ML...

Quote from: feureau on February 11, 2013, 11:34:46 PMLast I heard there's some talk on figuring out the line skipping/pixel binning thing?

Does that mean there's the potential possibility of being able to improve the video quality somewhat by intercepting the data before it gets line skipped etc? Interesting... I assume the whole line skipping thing happens to reduce the amount of data thrown at the encoder, otherwise why would Canon use this method?

Quote from: Brawl on February 07, 2013, 01:50:44 AMI need to know if possible: can the current ML firmware for 7D archive the possibility to have custom bitrate?

Yes.

Quote from: Brawl on February 07, 2013, 01:50:44 AMI have explained to my teacher that Magic Lanter allow the user to select custom bitrate to have some kind of "raw" files, I said him that having a super bitrate allow the filmmaker to work in post processing without the fear to loose in detail after having done the job. Can we do it with 7D and ML aready?

Increasing the bit rate is not the same as the camera recording RAW video data, which is not possible at this level. Basically you can think of increasing the bitrate as a way to reduce compression and blocking artifacts in highly detailed or high-frequency noisey material.

Quote from: Brawl on February 07, 2013, 01:50:44 AMIs the firmware almost stable to install it to the 7D of my teacher (I risk my head eheheh)?

ML is an Alpha-testing release, therefore should not be used in production, and there may well be issues. However, most people have found it reasonably stable so far, so there is no problem in using it, particularly to play around and familiarise yourself with the features etc. Just be aware that there are no promises of stability yet...

Just a little polite notice for everyone asking "when will XXX be done..." the answer is mostly "don't know" or "when it's done".

The ML team work on things in their spare time, so development has to fit in around what those guys are doing - not only that, but the nature of development, especially the kind of reverse-engineering that goes on in the case of something like ML, is unpredictable. A single issue might be fixed in five minutes, or it may take six months to solve.

Chasing the devs for ideas about timescales, feature implementations and so on is a little pushy. They will get to it in their own time and announce what they are working on and so on here. So feel free to ask about features, the progress of things and so on, but the "when" question only really serves to slightly irritate devs.
#12
Not sure whether this is a bug, a general ML implementation detail or whatever, but:

If I set Movie Rec Start/Stop to a half shutter press, it works as expected. However, I have back-button focus setup (AE Lock Button -> Metering & AF Start) and do not have focus on the shutter button. If I hold the "*" button to focus, on release the camera will go into record mode - in short, when movie start/stop is set to half-shutter, a back-button focus operation will also cause a movie start/stop operation.

This is contrary to the behaviour I would expect :)

I would like the back button to not trigger movie start/stop, so I can focus as usual without starting/stopping recording...

Also - I wish quick erase would also work for movie files, it only seems to work for picture files...
#13
Nice feature, I would definitely use that...
#14
I'd find it really useful for my workflow to have some more options available to assign to buttons, particularly the SET and DOF buttons.

I guess the thing I use most is navigating through the menus to the Flash Control menu (to change remote flash power etc). I'd love to be able to set this menu to come up when I press the SET button, rather than having to navigate through sub-menus every time.

I guess an option to choose a particular menu or sub-menu screen to be displayed when pressing SET would be a nice general feature that users could choose and customise to their needs.

What do you mean? The short was shot in a ski-area and I went on a skilift with my 7D and just shot some trees :)

"Right, I need this tracking shot through this car park. Ok guys, you can rig up the skit lift here..." :D

Quote from: DaveVegas on January 02, 2013, 02:38:08 PMI definitely experienced a wider range of possibilities while grading, also the noise reduction didn't result in a mess as it usually does

When you say noise reduction, are you doing this in post, and what ISO where you typically shooting at?

For me, while NR does get decent results, it's very easy to blur the image too much and lose detail, and the NR batch process is really processor intensive which is a bit of a pain.

Quote from: DaveVegas on January 02, 2013, 02:38:08 PMBy the way my settings were balanced, VBR, Q-16, Flush 24 (Because of sound) and GOP at 1

Thanks for that, I will give this stuff a try - I've just been reading through the bitrate monster thread to get some overview on the settings...

Quote from: DaveVegas on January 01, 2013, 11:42:30 PMA little shortfilm called "The Visitor". I shot everything on a 7D with bitrates between 100-150mbps and all I-Frames. I really did see the difference in post.

Nice, Dave! I'm not going to ask about the opening shot... ;)

What was the difference in post you speak of? More flexibility in the grade? Or for VFX?

Nice work on the sound design too.

I'd really like us folks to boil down some preset settings for the bitrate feature, because at the moment I don't really understand what many of the settings are doing and sometimes judging the interplay of a few of these variables can be quite difficult to discern and understand the behaviour of...

Just a follow up on this:-

Quote from: beej on December 28, 2012, 03:36:57 AMA question on rack focusing.

One slightly frustrating thing - when altering the steps to here value with the top scroll wheel, moving it fast (which you kinda have to do with a step size of 1 for it to go anywhere, as you want values of +100 or more) often comes off the parameter (especially if the soft-limit is reached, but it will often come off the parameter without that happening) - and then you are now scrolling fast through the menus. Not only that, but there is no way (I can see) of continuing to adjust the steps to here value without first zeroing it out and starting again. This makes setting up a rack focus operation quite painful, currently.

While this is all true, I've just discovered (duh!) that changing the focus steps using the top dial is not the only, and certainly not the best way of changing the parameter. Using the multi-controller instead moves the steps continuously, rapidly and smoothly, and doesn't "run off the end" in the same way the top dial does, which goes a long way into making the feature smooth to use.

Just in case anyone else is running into the same issue. I'm really going to be using the rack focus feature a lot (it is one of the features I really like on my Sony Z5, along with zoom and aperture ramping, but without that super-shallow depth of field it's far less sexy than a DSLR...).

I think they said they disabled the donation links for now, as donations have funded the immediate needs of getting IDA licenses to help with development.

okay uzipped all the files from the ML downloaded file onto the CF card placed in the camera went to firmware on the menu pressed set (current version is 2.0.3. Update press ok firmware up date program, sensor screen came up on back of screen and the red light by the cf door flashed. firmware ver. 2.0.3-ml-v2.3.next on the screen now, but don't see anything new :(

Ok, you're up and running. Now you need to learn how to use it. Press the Trash button, and read the docs :)

Quote from: markymark on January 01, 2013, 07:02:50 PMdo I just uzip it straight onto E: (no need to put it in anyfolders ?)

Yes - that's what "root" means - the top level, not inside any folders.

Quote from: markymark on January 01, 2013, 07:02:50 PMAlso is it just the MAGIC.FIR that I unzip on to the card or that and everything that is in the ML folder ?

Step 2, Installation docs:

"Unzip all of the files from Magic Lantern zip archive to the root of your card."

Just follow the docs exactly, don't change steps or second guess them... :)

Quote from: g3gg0 on December 30, 2012, 11:48:41 AMyet i have to think about how to make this power-user feature normal-user-proof.

what about the others? are you using video hacks? do you see use in them?

For me, I'm mostly ok with the default video quality - however, I would like the option to engage a "higher quality" mode for important footage. So, I'm wondering if the feature should basically work something like the following:

A menu option called eg "Video Quality", which lets you set to "Canon Default", "Better", "High Detail" and "Custom" or whichever presets make sense in light of user-testing of what settings work for what application. Then a power user could either hit the Custom setting and get into all the specific bitrate parameters, or hit the Q button to see the settings for each preset and tweak/save accordingly - perhaps even create their own presets for their own use.

So basically - for me I'm personally not generally that interested in tweaking all the various bitrate settings to work out what works for me - simply the ability to toggle quickly to a "higher quality" mode for important or highly detailed footage is all I really require, with the ability to go in and tweak the settings if I really wanted to.

Quote from: markymark on December 30, 2012, 06:02:10 PMHi, need a bit of help, I am very new to all this and own a 7D which I wish to do more with the HDR setting. At the moment the 7D only lets you take 3 images can this be increased with the ML firmware update and if so how many will it allow me to take ?.

Yes - up to 9 shots. It's a great feature!

Thanks for the great work on ML for the 7D ! I really love it, but is there any way to start ML automatically when the camera boots ?Is this feature considered to be part of Alpha 3 ?

As mentioned many times in all the alpha docs and forum threads on the 7D port of ML:-

That will come when the 7D port is stable - for now, this is intended as a testing release only, not for production work, which is one of the reasons for this limitation - the other being that apparently the boot procedure needs to modify certain camera properties and the devs aren't comfortable doing this yet while there is a possibility of camera brickage...

Is the bulb ramping for timelapse feature enabled in this alpha? (I think it was blocked waiting for some of the same property setting stuff that the HDR features needed, wasn't it?)

Yep, all of that stuff is now in there, bracketing, intervalometer, focus ramping, bulb ramping etc. I haven't played with bulb ramping yet though.

Quote from: sanderroeling on December 28, 2012, 11:15:46 AMI'm very new to ML And testing it right now on location But i can't Find the HDR feature. Camera mode is set on manual. It should be on the movie settings, called HDR right?

If you are talking about HDR photos, then you want the advanced bracketing function.

If you are talking about the HDR movie feature, it's not in the 7D alpha yet, afaik.
