Nikfreak, don't forget Bitrate Control and Dual ISO in the 'what's not working' section 

Right now I familiarize myself with the ML, must read some manuals on how to use some of the functionalities.
I tried already RAW recording: with 1280x720 my Sandisk Extreme card rated for 45MB/s couldn't stand more than a minute of recording.

I'm guessing your card peaks at 45MB/s but at times dips below the required 36MB/s for 720p raw.  Speed ratings on SD cards are very snaky, you really can't trust them.  I bought an SD card rated for 90MB/s writes just to be sure, and so far I've never had any interruptions at 720p.

The left over ML folder, where is its location? Camera file system or SD-Card?

To be more precise: Will anybody be able to see that ML had been installed?

It's on the card.  When you plug the card into a computer, you'll see 3 folders: DCIM, MISC, and ML.

DV I sent a tech. request to Canon with concern that there was a 70D firmware release made about a year ago.
I wanted to know what bugs were fixed, and how I could download it.  I also pointed out that
having two firmware versions of ver 1.1.1, is poor software configuration management SCM practice.

I suggest you do the same, as the more that complain - hopefully they will provide an update.
My fear is that they did this covertly because they changed/upgraded h/w and didn't want to notify 1st gen. owners.

Actually Canon is ISO 9001 certified. It is a major violation of that standard to have improper SCM practice.
If their ISO auditors find out, possibly they will be forced to remedy it (however that's a longer process).

Yeah that does sound pretty shady.  And not really legal.  If there was a HW change then the camera needs to have a different model number.  And I would guess it was indeed a HW change, otherwise why wouldn't they publicly release a 1.1.2 FW?  So I guess that kind of eliminates the idea of sharing the "new" 1.1.1 with everyone because if there's been a HW change that probably wont work so well.

Johnny, the menu override in Canon menu while selecting the option to format card works. You can switch with "Q" button to format card and retain ML on camera which I tested and that's working. There's also the option to remove ML but I didn't test it. Should work but I cannot guarantuee that it works because I didn't try. I will test it myself later and give an answer on that. Till then I don't recommend you to use that option.

Yes, removing ML this way does work.  It does leave an ML folder that only contains a config file but removes everything else, it no longer runs after doing this.

how to differentiate the two version 1.1.1

The only way to know for sure is to try the installation.  If you can enabled bootdisk, you have the new revision.  If not, the old one.  For those who have the old FW, I wonder if it's possible for one of us with the newer version to rip our FW and share it?

[never]

Tell me please, at what resolution 70d can shoot RAW-video for a long time? For example, 5 minutes. And can anyone make an approximate test quality at this resolution and FullHD on H264?

16:9 no-stretching: 1280x720
16:9 1.4x stretch: 1536x864
2.39:1 no-stretching: 1536x642
2.39:1 1.4x stretch: unsure, will update

All of these are assuming 24fps and an SD card that never dips below 40MB/s, not even for a moment (many SD cards, despite being advertised to write way beyond 40MB/s, will experience random drops that could stop your recording or result in frame skipping).  By 1.4x stretch I mean recording a squashed image and stretching it vertically by 40% to get the listed resolution.

@dmilligan --Thanks for the enormous info regarding this particular requests... Definitely not worth fiddling with this due the points that @a1ex made earlier which I'm afraid it simply puts the foot on the floor!

CBR's can be a fun feature but is it really worth esp with the cons outweighing the pros?

Here's my personal take on it: yes, error checks were bypassed and it's not 100% "safe".  But it never bricked anybody's camera when it was being used in TL.  To me, it is worth it.  I'd like to squeeze every last drop of quality out of 1080p h264 that I can get, because I really don't like working with sub-1080p resolutions and I don't have $3.5K for a 5D3.  But like I said, I'm not a risk-averse person and I definitely understand now why it shouldn't be in the main public build.

I don't see why they would disable something like that if there wasn't a hardware limitation.  But I guess it's worth looking into as it would be extremely helpful for situations like that.

Right.  I certainly don't wanna cause another community split or anything like that.  It would just be a personal build really (if I could actually copy it successfully).

nice video and lovely cats! so the top is still ~6 secs?

Specifically around ~135 frames, so closer to 5s at 24fps.  Not too great.  Lowering res will obviously grant a few extra seconds but at that point you might as well drop down to something sustainable.

Hey, im writing in connection to sd card slot limits... maybe the solution is to use wi fi module from 70d?
I knew that it had to be extremly fast wi fi connection, but would it be possible to sending all this raws in realtime with some high speed router? Or mayby divide output to all these 3 possibilities (sd, hdmi, wifi) not just 2 as you said before?

What walter said.  Wireless N is dependent on the number of antennas, the 70D probably only has one (based on Canon's defining 150Mbps) and that's only achievable without signal interference, which is the other problem.  Even if it could transfer at 600Mbps, wifi is easily interfered with and rates fluctuate.  It's nowhere near reliable enough for writing video files in real-time.

Hmmm.  Thanks for digging that up for me!  I'm usually one to throw caution to the wind, but I understand that risky disposition should not be forced upon the entire ML user base by putting it in the unified branch.  Looks like if I ever want it, I'll have to try making my own build and maybe share it on a per-person basis as long as they acknowledge that they understand the risks.  At least for now a few models support GOP 1 in the default FW.

Which I do, although I'm not sure Qscale -16 actually sets the highest possible QPs

I really dont think it would be that difficult to bring the old code into the latest ML builds.  I would also like to see the 3.0x limit removed, basically allowing you to raise it until your particular camera can't write any faster.  I can't even think of a reason why these things would be removed in the first place, unless someone thought they were useless.  But just because it's useless to one person doesn't mean it's useless to everyone.  For those of us who can't shoot 1080p raw it would be nice to at least record 1080p h264 up to 40MB/s, setting GOP to All-I and QP to the highest you can get.

The old TL code is still readily available in the TL repo, and I think the 7D 20.0x bitrate experimental code is still in the ML repo as well.  My programming knowledge is shaky and limited and I'm still just beginning to familiarize myself with the code base so I'm nowhere near confident in my ability to do it, but if nobody else does it I might just try to make my own 700D and 70D builds with the old bit rate control code.

Here's a few random 1856x1044 raw shots.  Literally no editing, just stretched to 1920x1080 and converted into an uncompressed 422 YUV 10bit mov.  Just uploading because cats  and to show the black bar on the left.
EDIT: Good lord youtube ravaged the quality... if anyone wants to see the un-violated raw footage I'll put it on google drive for download.

Any of the pre-alpha testers available to do some dual-iso test stills for us?

Will do tomorrow when the sun is back out.  Might test out dual-iso raw video as well.

EDIT: Unless I don't know what I'm doing, dual ISO is not currently working.

So Bluey what's the max. res for 10 sec? FHD, and with 2.35:1 aspect?

And DV 70 degress is too hot.  Try and keep the LCD off the back, as that will help a small bit.

Yikes.  You mean turn the entire LCD off? Kinda need that    I wonder if it's ML making it hot or if my particular camera just runs hot, because I did a shoot with it a couple weeks ago (no ML obviously) and it got very warm in my hand just shooting h264.

Regarding your first question, for what it's worth, I can get around 5-6 seconds at 1856x1044 (16:9) 24p before recording stops.  Haven't tried anything else yet, but I'll see what I can get for 10s at 2.35:1

DV " Is raw video 4:4:4 or 4:2:2

14 bit raw refers to the sensor data.  Each pixel is 14bit of information.  When a CODEC is applied, it converts/compresses this to 4:4:4.  H264 compression is generally 4:4:0, which is the delivery standard.
Adobe raw codec works with 4:4:4.  The big difference in the 0 vs 4 is in the colour range/granularity which the human eye is really not able to distinguish that well.
Again the goal is to export your final delivery in H.264 4:4:0 as that's what most TV's are.  That's my limited understanding.

Do you mean 4:2:0?  I haven't heard of 4:4:0.  But yes 4:2:0 is fine for your final product as you wont be altering the image anymore.  For editing you definitely want 4:4:4 as that gives you way more flexibility to color grading, effects, and other alterations.  Editing a 4:2:0 clip too heavily can quickly turn it into total mush.  I was just assuming ML raw was 4:4:4 because it's just a straight copy of sensor data, but I wanted to confirm whether it was or not.

Also, what's considered a dangerous temperature for these cameras?  My 70D has regularly been reaching 70-80C while running these early alpha builds, I don't think my 700D has ever gotten that hot.

No.
g3gg0 did it.
I couldn't even port ML from 2.0.3 to 2.0.5 on 7D...
But I can help to the more skilled developers with testing, finding stubs, etc.
Unfortunately none of them interested to do it.

Gotcha.  It's a shame there hasn't been interest in the 7D2 yet, it could be the first camera capable of recording max-res raw at 48fps or even 60fps with no squashing.

I still wish we could just "cut off" the 2 or 4 least-significant bits when doing the EDMAC copy from sensor to card, I'd definitely exchange some depth for some increase resolution 

Although I guess if you do the math, even lopping off the last 6 bits still needs over 45MB/s for 1856x1044 raw, and 8-bit sucks for editing...

I think the camera has so much potential, with ML it could be a jackpot...
The CF and SD card interface is already fast enough for RAW video and there is an USB 3.0 to get more speed.
I'm happy to help any developer with testing, dumping, etc.
I have Sandisk 160 MB/s CF and 95 MB/s SD for speed test. 

Pelican, you made the original 7D port right?

I made a RAW vs H.264 video, I think its a big step up! Make sure to hit that HD button.

Yup, the difference in detail and color is unbelievable, even after YouTube's disgraceful compression.  What resolutions did you shoot for both the raw and h264 clips?

Also, speaking for raw, random noob question: Is raw video 4:4:4 or 4:2:2?

no problem, glad i could help 

So how difficult was it to remove the 3.0 CBR limit in the source code?  I'm interested in trying this myself on my 700D.  Also, does Qscale -16 set the maximum QP possible, or is there still room left to go?  Lastly, it would be really nice if we could get GOP control brought into the main ML branch.

Good to know !

I think there're a lot a new possibilities with this 70D, even if it is limited by the use of SD cards for RAW video, compared to 7D's/5d's. I often need to edit my videos really quickly, and RAW needs too much time and a more complicated workflow compared to H264, so shooting in raw not my main concern for the 70D. But still an amazing thing.

Canon's h264 is so gross (to me), especially at the default bit rate.  3.0x is not much better, but it's still a slight bump (and hopefully ML is updated to remove that limit at some point as 20.0x has been done on the 7D).  I feel embarrassed doing paid gigs with h264, but it's all I can manage on my limited budget right now.  14-bit raw is truly awesome, I really hope we can figure out how to write footage to attached USB storage, that could theoretically raise the max write speed to 55-60MB/s with dual writes, which may be just enough to get squashed 1856*xxx at 24p continuous.  Otherwise maybe I'll have saved up enough for a 7D Mark II by the time it gets an ML port (although I'm not so sure I wanna stay with Canon)

I don't think you can modify video AF speed. I couldn't find any options, anyway.

Correct, you can't.  The 7D Mark II introduced the ability the customize AF speed, although it does seem like the type of thing ML can possibly do.

Just got my 70D back after lending it out for a bit.  I'd love to test out an alpha build on it 

Has anyone with a pre-alpha build of ML tried setting ALL-I compression with 3.0x bit rate and the bit rate overlay on?  I'm curious if the camera actually reaches 270Mbps, and if it can do so without the encoder stopping.

Interesting.  Like I said, 1.6.3 was the only version that worked for me also.  1.6.5 wouldn't accept my mlv files.  I figured the problem was W8.1 and that it would be fine on W7.  Maybe for now it's just best to shoot raw instead of mlv, there are more options for raw.
