Tragic Lantern for EOS M

[gary2013]

Jerry, I just finished the long format on the 128 gb card. I ran eoscard with no options selected and hit alt f and the did a quick format. I then installed ML back on the card. I used the rootwang version and the common fir file we all have used. I turned on the camera, started all the modules, i started the dm lof, i pressed the shutter five times trying to take a picture in the pic Manual mode and the bug was there. I stopped the dm log and turned off the camera. here is the link to the dm log file

Gary,

just to be clear, i have a couple more questions.

128GB:
ML installed
Shutter bug

32GB:
ML no longer installed
With ML: shutter bug
Without ML: no shutter bug

is that correct? sorry its hard for me to follow. i may be tired...i'm very tired, so i apologize if this is redundant.

Gary, i don't think it matters which build of ML you are using. i have the latest and greatest ones on http://ml.bot-fly.com and they are as good as any.
here are the links

http://ml.bot-fly.com/magiclantern-v2.3.NEXT.2013Sep17.EOSM202.zip

extract the zip to the card and put the .FIR in there to run the firmware update

[gary2013]

everything is correct bexcept for knowing if the bug was there when using the 32gb card. I have been only using the 128 gb card for a long time. Let me try ML on the 32gb card and see if the bug is then there.

I don't see the SW1 triggering in there nor the Cancel messages that seem to be associated. No idea what this means, but it seems that your bug may be different.

[gary2013]

good news. i put the rootwang version on my clean 32 gb card and flashed it and tried taking pics with a few times of on and off and on again waiting 10 secinds between each cycle and no bug.

so, it now looks like it is just down toi using cards bigger than 32 gb and also the eoscard. like when I started out here two months ago.

another big question? then why did the other people with the same lens have the shutter bug like I did? ?

we will need to be able to shoot with cards larger than 32 gb, especially witrh raw.

[jerrykil]

Oh! sorry. gary, don't turn on anything when you start the cam. just start the camera, start dmlog, snap a few/try to snap, stop dmlog. and gimme. what happens is the dmlog buffer fills up and i'm not sure but it looks like your log is cut off at the end

[gary2013]

when we install ml the first time all the modules are off. i turned them on so now they are all on. i did the steps you say. what now? turn them all off and then do a dm log?
gary

[jerrykil]

yes keep them off, just so there are less miscellanies things in the logs

[jerrykil]

Hey guys,

I made a new thread, just cuz this is getting long:
http://www.magiclantern.fm/forum/index.php?topic=8347.new#new

see ya there!

[gary2013]

here is the new log file. careful, it has the same name as the previous file.

https://www.transferbigfiles.com/8ae50076-f3b1-4f6e-b0dc-362ebae15d02/5L2sa7GwJXqvFBHL_iIbIg2

this is the 128gb card with ml and all the modules were off when i turned the camera on. i made five attempts pressing the shutter button to take pics at a slow pace and the bug is keeping me from taking the pics.

How did you compile signed fir?

[jerrykil]

i didn't. am i in trouble?

[feureau]

You are now. I've just notified canon's lawyers.

[Malakai]

Heres a question. With ML on the EOS M. Would it be possible to have custom picture style files saved on the memory card and update the picture styles on the camera without having to do it via a computer?

No.

I asked this on the feature request part and it's pretty much can't be done.

I have a question about crop mode. This is a perfect tool I can use C mount lenses on Eos-M (the only canon eos camera  can do that) however I end up with small AF points all over the image . I can remove the af points in regular Raw mode with pinkdotremover but this doesn't work in crop mode. The dots are there unfortunately all over the image, the crop mode will be great otherwise, less moire/aliasing. The other issue with crop mode is that I cant record higher resolution than 1280 x720 24p on my Sandisk extreme PRO 16gb card. Am I doing something wrong is there any way how I can rid off those af points  Thank you for you hard work

@pizmon

I've been struggling with this issue for awhile, in fact, working on it when I saw your message! 

You can read some of this discussion between Rewind and I at these two start points

http://www.magiclantern.fm/forum/index.php?topic=3648.msg73969#msg73969

http://www.magiclantern.fm/forum/index.php?topic=8171.msg74860#msg74860

The problem re-appears

http://www.magiclantern.fm/forum/index.php?topic=8171.msg74439#msg74439

Yes, the c-mount lenses are fun.  Please give any insight you have on this forum.  I use the Fujian, but haven't tried others.

Rewind did a new version of PDR that deal with crop mode, the link is here.  Hopefully this will solve your problem.

http://www.magiclantern.fm/forum/index.php?topic=3648.msg74097#msg74097

I calculate the dots take up about 4.4% of crop mode image.  However, when effectively removed, don't seem to hurt image to me. 

Yes, 1280x720 at 24p is the most you can expect.  Limitations of how fast the EOS-M can write to the SD card.   I have a 50D where I can go 1080 at 20fps.  The image isn't that much better than the 720p EOS-M.  Also, it has 5x crop mode where the EOS-M can do a lighter crop because sensor is closer to lens. 

Glad you've come on board!

[pizmon]

Thank you maxotics! I will try pdr rewind . I just bought Switar 10mm 1.6 I will post something as soon as will get the lens. If 1280 x720 is related to writing speed of the card this alone should not be entirely bad news. I believe/hope there will be faster SD cards announced soon. Lets see and hope .

Thank you again I will post some video with switar once i get the lens

Hi pizmon
I´m afraid it has got nothing to do with the speed of the card  - the EOS M writer/reader isn´t fast enough. Around 45 mbits if I remember it right.

I am now having to look for a new card unless we can get some fix for using 128 gb cards/60 mb write speeds to work with or without the  eoscard.exe utility to avoid the shutter bug. Is it official now that the camera will only need a card that does 40 mb write speed? And that anything faster is not needed since the camera can only write that fast? would a 45 or 50 write speed card make any difference? what is the exact minimum we can buy since the price will make a difference when buying cards.

My recorded footage is between 80-100mbps on a MyMemory class 10 UHS 1 card with ML bitrate set to 2.1x... but thats not capturing RAW.
IMHO i think the read/write speed of the camera is classed at least UHS 1 because anything over 100mbps and I get buffer issues and recording stops. Canon probably limit the capture bitrate to 45mbps and use the buffer  to ensure there are less issues recording on slower cards. They should at least let you choose from a few pre-set bitrates. Just in case you have a faster card.

Am i right in saying that the EOS M only has a small (56mb) internal buffer. Perhaps this could be the bottleneck?

[maxotics]

Everyone who is new to this, including myself, confuses BITS and BYTES

MBs/sec (megaBYTES per second) 8,000,000 bits per second.  mbits/sec (mega BITs) 1,048,576 bits per second.  1280x720 24fps runs close to 39 megaBYTES (not bits)  per second (39 x 8 or around 312mbits in your current frame of reference).  The class 10 cards will NOT record RAW at any meaningful resolution because they write at about 10 megabytes per second (80 megaBITS not megaBYTES).  Even the 30MBs cards won't do 1280x720. 

Yes, 60 seconds of RAW video will take up over 2 gigabytes of space!  You need the cards that generally cost about $30/16GB 95MBs/sec cards.  Yes, the CAMERA CAN'T WRITE ABOVE 40MBS (you can fantasize, but I wouldn't, that it will change for this camera).  The 30MBS cards are too slow, the 45BBS cards are probably okay, but are probably not being manufactured much and price not much difference than the Sandisk 95MBs.  Also, some question if the 45MBS cards can always meet their published rating.

At least in germany the 45mb/s sandisk extreme cards cost just ~50% of the 95mb/s extreme pro cards (32,31 EUR vs 64,98 EUR für 32gb on amazon) and afaik they are fast enough. But if anyone has both, a direct comparison would be nice.

Are there still any problems with PDR? i'm not very active at the moment since i've to finish my diploma thesis until end of next week.
BTW latest ML version does crash for me while loading the modules. i use EOSM-COPY.zip (2013-09-04), mlv_rec.mo (2013-09-02), dual_iso.mo  (2013-09-01) and all other files from [EOSM]FullbackADTGui.zip (2013-08-30). don't know if that combination should work, but modules doesn't load for me at all.

I saw yesterday the Sansdisk 32gb 45 write for $30 and $60 for the 95 write in the US.

I have problems at first loading modules and it's different with each version. I have to keep trying with turning the camera off/on and then on and maybe after four tries it finally works for all modules. Sometimes I have to try changing a menu item that says modules off before they even show up. I don't remember exactly the procedure right now. I am away from the camera. Keeps trying and they eventually work.
