This is not a polished video on how to do this, but more of me working my way through it.

I got my new 1000X 64G KomputerBay CF card today and made a video of me installing Magic Lantern on my Canon 5D Mark III. I’m going to use it so I can shoot raw with it.

This is not a polished video on how to do this, but more of me working my way through it.

*** Get the most recent Magic Lantern files for the 5D3 here to shoot raw video. changed loction again.

Watch Charles Video here if you are looking for a more polished version.

Get the files from Charles video here. OLD

Read Andrew Reid’s blog post about cards that work with the 5D3 raw.

Magic Lantern forum post showing the folder structure you need to make raw work.

So the question is, should I send the card back in hopes of getting a faster one?

5D3 Settings

  • Make sure you’re only on single shot mode, multi-shot mode changes the buffer size
  • Long exp. noise reduction =OFF
  • High ISO speed NR = OFF
  • Highlight tone priority = OFF (just in case)
  • Global Draw off?
  • exFat on CF card format

Speed Test!

I was averaging 84MB/s write and 110MB/s in live view mode and now I am averaging 107.2MB/s Write and 137.3 Read speed not in live mode as measured by Magic Lantern’s benchmark card test.

I will not be making a video on how to do this for the T3i 650D because the shelf life on this video is sooo short!

But if you need help for the T3i, Filipe Gonçalves helped me out a ton and here is his instructions that got me started:

Install ML nightly build, I have just copied all files to the card overwriting the normal ML files (probably you should format your card and not do like I did)

Link for nightly builds:
http://nanomad.magiclantern.fm/nightly/

Then download the latest module:
https://bitbucket.org/OtherOnePercent/tragic-lantern-2.0/downloads

Avoid 800Fileman.zip me and others are having problems with it.
Still Sprinkle Free.zip is working fine.

Once you download the [600D] file rename it and add rar or zip extension, then uncompress and use those files to overwrite the ones in your card: overwrite “autoexec bin” and modules folder goes into ML folder.

Start your camera in video mode and go to the far right menu, chose load modules. You will see raw_rec. Then goto the movie menu and chose RAW movies, chose your resolution etc.

  • Hi Dave,

    The reason why it stops recording is related to ML software implementation not your card. Basically in the earlier versions they were afraid of frying the camera and therefore they have put a maximum of 4GB file size in the code. In later versions they have added an option in ML GUI to lift this condition. I find the latest version of the code in this link:
    https://drive.google.com/folderview?id=0B7QlH_BH2m32VmNkUWhFd194bHc&usp=sharing

    They compile the code every day and upload it in the above link.

  • Dave,

    Why did the recording stop at the end of the video? Did you run out of room, or did the recording just stop for no apparent reason?

    Thanks

  • Hey Dave, always fun to see the process from scratch. Can’t wait to see some more tests and how you make out with it since your stuff is always fun and informative. Right now, I’m just a T3i owner who gets to live vicariously while you show off your more powerful camera.

  • Hi Dave,
    I believe the reason you’re supposed to do the safely remove hardware thing is so that, if you’re copying data to or from the card, your computer can safely finish the process before ejecting the card or else the data being copied will only be partially complete. I’m not entirely sure if that’s the reason but it seems to make the most sense.

  • Hi dave,

    The 4GB file limit can easily be removed by formatting the CF card to exFAT. Also make sure you are using a ML build from later than the 19th of may.

    I have been able to record a 15GB video at 1920×1080 no problem with my 64GB Komputerbay card. Just takes forever to process in post!

    Hope this helps.

    Cheers,

    Adam.

  • i installed ML but when i record videos i cant find any saved RAW on cf card can anyone tell me why

  • Hi Dave,

    Perhaps it’s a silly question, but do you have to leave the SD card in when you’re recording to RAW to the CF card?

    I only ask because I’d heard that the write speeds were much lower on the 5dm3 when a SD card was inserted- even if you weren’t writing to it. But perhaps that’s only for stills.

    Also, I wanted to ask how you got better speed results out of your KomputerBay card- they appear to have gone from 80MBps to 100 MBps when you turned off live view? Is there a way on ML to benchmark without using LiveView, and if so was that the difference?

    Thanks,

    Trent

  • (A questions for Adam)
    Hi Adam,

    You talked about “The 4GB file limit can easily be removed by formatting the CF card to exFAT. Also make sure you are using a ML build from later than the 19th of may.

    I have been able to record a 15GB video at 1920×1080 no problem with my 64GB Komputerbay card. Just takes forever to process in post!”

    Please fill in two specifics:

    1) How long (in running time) was your 15 GB file?

    2) If Dave ran his test at 83MB/sec, it stopped writing in 25 seconds, that should mean that the file was only 2075MB or 2GB. I thought the RAW file sizes were coming in at 4GB.

    3) When you say “forever”, can you give it a number like “It took 4 hours to process four minutes.

    Thanks for any light you can shed on this my friend.

    Best,
    Fletch
