Hey 50D users I've started to port 50D to crop_rec , first step was to code a simple preset in where a1ex first tested the 5d3 code.
Reasons why I put the 50D crop_rec in adtg_gui is to make sure it work or course & a simple coding task for me ! Since I very weak on that I
being teaching myself (with the help of the internet  :D ) c code syntax , I'm slowing making good process , much to learn but it's worth it in the end  ;D

I can report working as expected with my 50d, have only experienced one freeze when the buttons wouldn't respond and the card led was solid, some reduced responsiveness but I expect that's due to the first version.

i'm getting around 7 seconds of 10bit onto my Komputerbay 1050x 128gb card.  Image looks pretty much as i'd expect, very impressed.

Thanks for all the hard work, lots of fun revisiting the 50d.

You probably can, nightly build on my 550d turns LV on automatically when you start the camera so there might be a way, i just haven't seen one yet.

Hahnel have also just released some new orange high capacity batteries, they also claim to be supper rugged. Not sure they do a BP-115 version though.

That Comparison sucked, and call me crazy but the second shot inside the shade looked like the 5D was sharper and had more detail overall.  Yes the GH4 shoots 4k but that doesn't mean its good at it.  I would gladly take the 5D Mark III RAW Video and High ISO performance over the crappy High ISO and Highly Compressed footage from the GH4 not to mention the crappy Lens lineup too. I was surprise Dave Dugdale sold all his canon gear to shoot GH4 and A7s.  It makes no sense,  RAW gives you so much more Possibilities in post.  Only thing you can do with the 4k Footage is crop.

IMHO you couldn't be more wrong there, I've just bought a GH4 after shooting ML Raw and i'm very impressed, I can see why with a speedbooster Dave Dugdale did what he did. The high sensitivity performance is not bad at all, it is average, alot better than any canon bar the 5d3 1Ds and 6d. With the correct curves in camera and careful exposure the amount of latitude in post in very very good. I've tried a 70d, it was like digging up the garden with a small trowel and a broken wrist as a opposed to the JCB that is the GH4.

Detail and sharpness in a 5D image is deceptive, Your probably looking at aliasing and god knows what other nasties, I doubt that's real detail.

Yes the GH4 is compressed, but its done so well the resulting image if your doing it right is truly stunning, my mouth dropped when I pulled out the card and watched on a nice display after my initial test. I also love not worrying about batteries getting killed and changing 64gb cards every 15 mins, in fact its bliss.

But there's still a place in my heart for the canon raw, it is such a nice image in every department other than the aliasing and rolling shutter issues.

But don't kid yourselves folks, IMO as a video camera goes, the 70d does not hold a candle next to a GH4, sorry.

You need to use the magic lantern "clear overlays" option, located in the global draw menu.

However you may not get 1920x1080 or 16:9 at all, the 700d may have improved on this however, but I highly doubt it.

Basically you will get black bars in the image and you'll need to crop in post and loose resolution.

It's really something you needed to have reasearched before dropping the cash.

Need HELP! When I use an external monitor via HDMI (Phottix 7"), I have some magenta artifacts on my pictures. Do you have any idea how to fix that?

You can have that occur without the monitor, it occurs when you use global draw when recording on the 550d in my experience. It is also more likely to occur in MLV.

I actually really wanted to see footage from this year, thanks so much for uploading it.

Footage looks really gorgeous, I wonder how you got the shot across the street panning from nationwide and accessorize, looks like a stedicam operated by a giant!

Like I say, amazing footage. Wouldn't mind going to see that projected in 2k in a cinema :)

Is there any room in the the housing for say a sony battery plate? one of the NPF550 should last you a few hours and you can switch the auto sleep off.

Yep, go with resolve lite, cleanest way of handling them, if you want to direct to log esque video, just setup a powergrade with the LUTs you like and get it yo render all the clips to prores or the like.
Usb2 is 480 megabits. We are in need of 80 odd megabytes. 80 megabytes is 640 megabits. It's also serial, and very very bad for continuos data throughput.

The camera would have no idea what to do with a IDE slot. You also need to fool it's card door into keeping it powered up.

We can't be sure the SD is the only bottleneck, we won't know until we can fix it, which isn't going to happen.

In short full hd possible is pretty much nonsense.

Also consider what HD means and wonder if a bayer patterned output around 1800px can ever be HD?

I got TragicLantern on 128 1050x from KB on 50D.

1. format from Canon GUI
2. copy ML files from older card
3. use EOSCard.exe utility to make the card bootable (also click on ML button in the utility)
4. install firmware update via Canon GUI
5. reboot

It's fast!


I did the same thing but used MacBoot, again perfect. Working 128gb KB 1050x in a 50d.
I've tried various codecs but Youtube seems to attack them all these days, even if you give it exactly what it says it wants.

Some people are upscaling to UHD (4K 16:9) which seems to help.

But what seems to be a common theme is the addition of grain, by adding lots of fine detail to the footage youtube's algorithm seems to leave it alone, I've noticed it help on some projects I've delivered but not all.

I've been running both 550ds and 50ds off the catclaw device using a pair of Sony NPF-550s, haven't seen either one overheat yet, temps aren't rising quite as high or as fast as batteries when in use. And due to to a proper 7.4v output, no need for a regulator.

Manufacturer claims 12 hours life, and I see reason to argue at this point, I haven't tested it, but a few 2 hour sessions and its still running on battery set number 1.

Hi all! this is my first post, i just to install ML in my t2i, and test around, there really great to raw filming!, so i been thinking about of the memory matters, and capabilities of t2i, is a good idea compile a build, with only Movie mode, can be reach more memory and resources for processing raw video?
Is very possible that my question can be a trash! jaja be free to ignore.

Its not going to be easy to switch off those canon modes, ML runs on top of DryOS rather than replacing it.  You could try switching off every other module that you don't need and switching off GD, but it probably won't help, the files your writing are so large that you'd need an enormous buffer to cope, there just isn't one there.

Yeah, just checked. I even reset the ML config settings and the back wheel still does not function in the ML menus when I have Live View activated. It still changes the aperture when the menus aren't up but it's useless once I hit the trash button. Still works fine in the Canon menu though. Using the build from 8/8.

[Edit] And like that, it works now. So weird!

My main thumbwheel on my 550d often behaves like this, too, it'll stop working until the camera is either restarted, or left to chill for a few hours.

Maybe it's supposed to work like this, but is there a reason why the quick wheel on the back of the 50D becomes unresponsive in menus after activating Live View?

Stupid question, but is your power switch all the way up? clicked towards wheel.

Now a wise man once said that,
"Did I mention that dual iso (11EV) 14 bit raw blows the snot out of a Black magic pocket camera 10 bit raw with a teeny-weeny sensor ... So if you shoot dual iso raw be prepare to be gob-stopped."
- Well it turns out that the 50D, which can be had for about $500USD, has 11EV of dynamic range from dual iso in raw, and combined it tends to blow the ... well you know. 
Lets see, bigger sensor and 11EV more dynamic range (which makes an APS-C seem closer to a FF),  all for less than a quarter of the money of a BMPCC+speedbooster+monitor+rig (yeah it needs a rig!).
... hmmm tough choice.  And a 70D with dual iso raw 720p@24fps (when it arrives), auto-focus, with 3X lossless zoom for anti-aliasing, even better still for film ... 

Still doesn't change the fact that the 50d can't do dual iso video, its a dead horse point.

The smaller sensors have advantages too, they increase depth of field making critical focus easier, they also tend to make everything look sharper for that reason, which is why all the blackmagic pocket vs other things look sharp because they haven't compensated for the DOF change.

I know this is an enitrely different subject, but can anyone recommend cheap anamorphic lenses? Are people having good luck using the Letus35 or SLRmagic adapter?

Its probably not wise to advise anything with cheap and anamorphic in the same sentence, if your after the effect then maybe. But if you want to use that whole 50d sensor area i'd be very careful. Even a very good anamorphic is likey to do some damage, but might help you benefit from more resolution. Use a bad one, or even a half decent one and it'll look like you permanently added a Vaseline vignette.

If you like the look, awesome. But if your after a resolution increase and very subtle "cinematic" anamorphic effects its going to get very expensive.

I've looked a fair bit at the century optics 4:3 to 16:9 and i'm not all that impressed. Same goes for the projection lenses. The Bolex was about the best i've seen, but again it was shown off by someone who knew what they where doing... The Bolex is also designed for taking, so you get a shorter minimum focus, rather than the mess you get with projection lenses and diopters.

The way to do it well is to use actual anamorphic taking lenses.

OK, so I have done quite a bit of testing with my 600D/T3i in raw.  Based on my testing I can start to project what to expect from the 70D raw (assuming some dev can deliver such a build for our humble testing).  Certainly the continuous focus is the main draw (for now and in this snack bracket). Firstly lets deal with the pretenders, the Black Magic pocket camera, the sensor is smaller (3/4) and it has 12 bit colour depth. If you compare to 12 bit depth and bigger aps-c sensor (I realize this is new ground for aps-c users who keep getting put in our IQ place by FF users) then you realize size and depth both matter.  Personally I would rather buy a used 50D and shoot in 14bit raw with dual iso, then a 12 bit Black magic 3/4 sensor anything camera.  I mean if you are going to wait that long to process your film then why stop at 12 bit blah!I think some H264/MOv of the 70D can match 12 bit raw blah adequately.  Its in the physics 14bits beats 12bits, so sorry BMPC users suck it up.

So lets cut to the chase, the bottle neck on the 70D in raw is the SD card write speed, which is 40-45 mb/s.   This is the albatross we have to deal with.
This is what I learned from my 600D/T3i:
1. Anamorphic means higher resolution than 16:9.  If you want to shoot a film, then 2.39 aspect ratio is your friend. I am not sure what the highest ratio for the 70D will be, but I can tell you that with the 600Dat half the SD write speed, it can go 1142x482, which is 80% of 720p anamorphic.
2. With a SD write speed of 40-45mb/s, your best option for 16:9 aspect is 720p (1280x720). Compare to the 650D which has the same SD controller speed.  The 650D supports continuous 720P HDDVD  at 24 fps (cinematic quality). That's what to expect with the 70D.
3. Now lets say, you want to use the awesome continuous focus of the 70D at some high frame rate or 1080p res., then you may think that based upon a slow SD write speed, you are SOL.  Well if you have a shot that is slow camera movement and slow motion (OK I mean an establishing shot), then you can shoot raw at higher res. with a slower frame rate (on my 600D I was able to shoot 1600x670 at 12fps), perhaps even 1080p anamorphic ??? (I am not sure what's the limit but with anamorphic you have a great chance to get to max. res.), then in post interpolate frames to add the missing frames.  As long as your shot is slow camera movement and slow motion this will work (Ok so lets just say real estate videos of properties are in the bag).

PS: Did I mention that dual iso (11EV) 14 bit raw blows the snot out of a Black magic pocket camera 12 bit raw with a teeny-weeny sensor ... So if you shoot dual iso raw be prepare to be gob-stopped.

Yeah yeah.... The blackmagic is producing 12 bit log, the canons produce 14bit Lin.  When you put that blackmagic footage back into resolve it "unpacks" to 16 bit lin. Therefore making it better...

It also has a super 16 sensor. Which is a long established cinema format with a wide range of glass.

The 50d also does not support dual ISO video.

It also in its aps-c mode us limited to around 1500px rather than the 1920 the blackmagic produces.

So all in all a pretty sill argument you made.

Hi all, not a magic lantern problem persay, but magic lantern has really helped me troubleshoot it.

Has anybody else got a 550D / T2I  a little warm and seen flashes of interference or noise across the frame?  It flashes across the frame for 2-3 frames at a time making the shot unusable. Always across the frame horizontally and always in the same place.

I see this when the camera is warm but often before the red thermometer warning, it seems to occur from ISO 800 up but I may have seen it at pushed 400.

I'll go through my projects and see if I can find an example to post.

We often have the 550d as a B or C cam to 7Ds at work, and i've often got it as my A cam. This happens well before the 7Ds start to even sweat obviously. I've never see a 7D do it.

Its been happening however the camera is setup, standard, gripped, ac adapter, ML RC, ML Nightly, no ML. So it appears to be something it does. Has anyone seen it, I'm interested to see if guys in hot places are plagued by it. It drives me mad and i'm in the normally mild UK.
I've had cameras behave in a funny fashion when connected to 7.4v supplies from batteries onto a coupler.

The 550d can get stuck in a sensor cleaning loop with a coupler with slightly low voltage in the camera. (Trys, fails, shuts down, repeat)
Place the same coupler with the same supply into a battery grip and it'll simply report "replace battery pack"

I also suspect there is handshaking involved, the camera saw and AC supply unit with too low voltage, but the knock off battery grip saw too lower voltage in general as it always sees AA batteries according to the camera menu no matter what is inserted.

Don't expect what a meter shows to be what the supply voltage is either, I would expect a 9V supply to be over 9V if you measured it without a  load.
I've got a home made EVF that runs on composite and I sometimes have the same issue (on the 550d)

Booting directly into video live view seems to be the issue, I believe its canons issue. try connecting the monitor and turning your mode dial somewhere else. Then trying to go into movie mode. That's seems to fix mine. Connecting to the AV jack with the camera booted up also seems to cause this issue.

It does work, but yes i've seen this happen.

Edit: I've also just remembered sometimes connecting the audio jack fixes it, I've wondered if its an issue with a common ground. So try that too.
The difference in use in video mode is negligible. The T5i isn't really up to decent ML raw, so you'll be at the standard video mode.

Slight differences in video modes on DSLRs mean nothing, the various downsides mean that these cameras are so technically bad they all end up looking very much the same, so it comes down to aesthetic.

The Canon will always have an upside in lens choice, the T5i will happily take Nikon lenses with an adapter. the Nikon won't take Canon glass, The Canon will also happily take most other classic SLR lenses and some cinema lenses.

Also be aware that what your getting is not HD, It might say it on the box and it might say 1920x1080, but it isn't HD and if you need your footage for HD broadcast ect be aware of using a DSLR. It is simply not good enough to produce the detail required for HD.

The GH4 that was mentioned would indeed offer near acceptable HD image if it was in 4K mode. But again don't be thinking your getting 4K, your not.

The other selling point for that canon is magic lantern. Which puts in alot of those features that the manufacturers forgot. Which may help you shooting documentary. Focus peaking and audio monitoring being key. But as things have moved on Panasonic have added those to the GH4. The GH4 also has the advantage that it can take even more types of lenses than a Canon DSLR, including brodcast style 2/3" glass which again might be useful to you.

So not a simple question at all, the best answer still is. If you want the best still photos, buy a DSLR and some nice lenses. and if you want the best video buy a good video camera and good lenses.
I'll have a 7.4v battery setup soon so i'll report how it effects my notorious 550d and 50ds.

Both like to get too hot and I hadn't considered that external power could help.

The battery itself getting hot contributes in the 550d certainly, using a battery grip helps a little.
Does this iMac have a thunderbolt port?

One of these might be cheaper and more useful that buying another machine.
