quick follow up, it was bad CF cards.  not a problem with ML or the camera.

thanks, all!

I also have read that some card readers can damage your cards, I was asked this question by Lexar when I returned a bad card.

thanks again, RenatoPhoto.  I'll move this to a more appropriate part of the forum after this...

used the recommended USB 3.0 Kingston card reader, so it's not that.  i'm guessing it's 2 different problems... someone once told me that Red CF cards don't work on some/any Canon cameras, so that may be one issue.  I looked at the pins on the camera and all seems well.  so I simply might have a bad KomputerBay card... forgot to test it pre-ML, my bad.

thanks!

Thanks guys!  That all worked.  Amazing how several of the guides don't differentiate between nightly build and 1st install.  I installed the nightly build 'magiclantern-v2.3.NEXT.2013Oct24.5D3113' on my 5D mk III and it works great so far. However I have a new issue...

I have 2 x CF cards, a new KomputerBay 64GB 1000X and a Red 16GB that was given away at a trade show.  I've reformatted the KomputerBay to exfat on my Mac and when the card is put into the camera, the camera doesn't start up.  It's like a brick, nothing.  Pull it out and everything is fine. I've also tried formatting the card as fat, also on my Mac.

The camera will start with the Red card but won't allow recording.  Something about 'Card 1 Cannot Be Accessed'.  Also tried reformatting it.

Any thoughts?  Bad card slot?  Bad cards?  Bad nightly build?  User error?  I'm guessing (hoping) for user error.

noob here...

i just bought my first DSLR, a 5D mkIII, and am trying to install ML but the nightly build seems to be missing the '5D3-113-bootflag.fir' file.  i've searched and can't seem to find it.  any hints?

apologies for probably missing the obvious...

(on an unrelated and off-topic note, almost all of the installation guides suggest formatting memory cards as exfat, but also say to format in the camera and not via the computer, which is a contradiction?... as i understand it, the camera formats fat unless the cards are 128GB or larger, yes?)

thanks

1.) Every other pixel is not currently possible FF since the data stream that gets sent is already every third and the ML dev's have not found any way to change that.

3.) Ok, the only thing that would get you even close is shooting in RAW and that always requires post processing work. ML cannot do anything to the size of H.264 at the moment. Just I case that wasn't clear.

Who knows what the future my bring, raw video was impossible a year ago.

1.) not wanting every other pixel in FF, but rather in an APS-C-ish crop.  but I understand this may still not be possible.  or did you mean in a Full-Frame camera?

2.) i would still be very happy to have a Raw APS-C capability, which would be quite helpful in my feature work.  but of course APS-C with everything would be ideal.

I guess this hasn't been added to the "can't do" list since there's still a slim chance.  but thanks for clearing things up!

I'm also going to assume that this feature might be possible as it isn't listed on the "Features that are NOT possible: Please don't request them" list. 

Sorry but I don't think it is possible to record that size at 1920. For raw there are only 2 options FF which is a data stream 1920 pixels wide reading every 3rd pixel from the sensor or 3x crop which is 3584 pixels wide without any pixel skipping.

In FF mode you can have just about any crop factor, 1.0 or larger, you want but you crop out resolution, there is no way to maintain 1920 wide. In crop mode your minimum crop factor is 1.6 so you can only have larger crop factors from there but again you crop away resolution.

FF
Any aps-c size you want but you cannot have 1920 wide.

you're obviously very knowledgeable but I'll wait for a reply from a Magic Lantern team member before considering my question answered...

some thoughts:

1. by your own logic, it seems that there's the chance that reading only every other pixel would result in something close to APS-C 1920x1080.  i'm not needing the exact size of APS-C, just in the ballpark.

2. i wasn't aware that the normal mode of shooting with the 5D is as a result of only every 3rd pixel being read.  in fact the articles i read at the release of the 5D mkiii claimed that it uses software downsampling vs. the line skipping of the 5D mkii.  but perhaps the signal is only clean if the downsampling is done in multiples of the resolution of the chip?  or am I mistaken altogether?

3. an APS-C-ish crop mode would have to be finished unto itself rather than requiring post work in order to be fully useful... much of the professional work that I've done requires the video to be completed or nearly so at the finish of shooting.  the producers download the footage to an HD (or, in some occasions, borrow the CF/SD cards) and are not seen again until the next job.

Thanks

There aren't? 50D and 7D and probably 5DII should.

No, I don't think so.  check out the current specs in Raw:

https://docs.google.com/spreadsheet/ccc?key=0AgQ2MOkAZTFHdFFIcFp1d0R5TzVPTVJXOEVyUndteGc#gid=5

1548x1058 for the 50D, and for the 7D it just says "can record FullHD only when also recording H.264".  I'm not clear on what that 'also' means.

and the 5D mkii isn't an APS-C camera.

I know this request has come up many times, but the only true thread I could find after almost an hour of searching was almost a year old and was quickly hijacked by those wanting a 3X crop mode, which I understand has now been implemented (great!). Apologies if this is kicking a dead horse...

some reasons for an APS-C crop mode on the 5D mkiii:

1. there are NO Canons yet that can do 1920x1080 at 24fps in Raw at an APS-C sensor size, yes?

2. this will allow maximum width of field-of-view on APS-C lenses without vignetting, so people with APS-C lenses can use them as we always have

3. those of us who started in 35mm motion picture shooting (me, for example) think in APS-C/Super 35mm lens mm terms, so it makes the transition much easier

4. a nice balance between workable depth of field and soft focus.  for me it is much easier to pull my own focus with APS-C than with Full Frame

5. it would be fantastic to have a Raw-capable camera (as opposed to Nikon) that can switch between the beauty of Full Frame and the practicality of APS-C


I am planning to purchase a 5D mkiii in the next month, probably on Black Friday.  what finally pushed me to the purchase stage is the Magic Lantern Raw release... fantastic job, ML folks!!!

I would much prefer the 5D mkiii over, for example, the BMCC because of:

1. better and faster software developers (mostly meaning you ML folks) and much better quality hardware (Canon)

2. i prefer the larger chip size (though my ultimate preference would be APS-C and even better still being able to switch)

3. the ability to shoot stills, particularly on a fantastic camera

Thanks,
Scott
