Hardware and Accessories / Re: DSLR Controller
March 31, 2014, 10:16:43 AM
Ok saw this on the XDA forums, had to stop in here. The problem is I believe the implementation of the DSLR Controller only interfaces with the Canon side of the firmware code. Thats the problem.

Magic Lanterns side is entirely separate with RAW recording. Magic Lantern bypasses the entire Canon recording process, and reads and writes directly to the CF card in RAW format. That's why you can switch off the liveview and gain faster read write times.

Unless Chainfire specifically updates DSLR Controller with a fork that addresses the Magic Lantern System specifically and not just the canon system you can probably expect this to continue.

Right now whats happening is DSLR Controller is attempting to pull and signal the Canon Firmware, which is currently being bypassed by magic lantern for speed and stability, since magic lantern hooks that code and pulls it into the code they've created, then it also pulls the power to send that signal and code over usb 2.0 to the phone. Resulting in code that shouldn't be working and hasn't been debugged, running concurrently along with magic lantern. Its like its trying to do double duty here not to mention the data squeeze trying to send image over usb 2.0 v_v I can practically hear the digic processors screaming their terrified screams.

Hah but anyways. You've basically got the phone addressing the old firmware hooks meanwhile Magic Lantern may or may not have taken them and integrated them into their programming and hooked them into other processes differently than the stock Canon Firmware, causing miscellaneous errors and system slowdowns. Especially with RAW.

RAW needs alot of processing power, every ounce of it that the DIGIC processor in the Canon cameras can give. All I can say is try dropping the resolution, liveview off, cf card tweaks (im a little behind on the most current builds but i think they still apply), external audio recording, as cropped as you can make the sensor, and you may get some stability with the least amount of dropped frames but I wouldnt hold my breath on that one.

Also ive heard mixed things about leaving the SD card in and having magic lantern run from that, or leave the SD card out for the Mark III have to experiment with that one. You'd honestly just be better off getting something like this and calling it the day.

Sorry for the info dump. Theres just really alot to it and its difficult to explain in a way thats understandable in few words.

The next time i start recording without switching the cam Off first, i get a still frame/image on the app... phuhhhhhh

Btw I do see that as pretty clear evidence that Magic Lantern is taking over the Canon Firmware processes as soon as RAW starts.

Duplicate Questions / CF Card External Recording Ideas
February 26, 2014, 01:45:55 PM
Just throwing around ideas, getting an idea of limitations. External recording via CF to SSD is not possible because of the bottleneck in data and processing power of the 5d Mark III.

Just some ideas based on things ive seen.

1st Idea to throw out there
Theres an DSTWO cart which can be used for game emulation on the nintendo 3ds. Now it has its own CPU built into it to help leverage more computing power for running those emulators.

Is the camera already attempting to write to the CF card by the time the data gets there? Would there be a possible way to circumvent writing of the data and instead make it a straight data transfer to a secondary CPU built into a custom CF card that could leverage a separate processor for writing the data to the card or even to an SSD via an interface like SATA.

2nd
Direct modifications to the 5d Mark II or III would be the only way to make this possible.

So basically you would need to engineer a custom firmware via Magic Lantern or whatnot and actually remove the CF card slot and circumvent the data transfer cap in general. So more of a hardware modification.

From what i've gathered SSD writing via CF card slot just is not going to happen.

Ok so its only if you are running RAW then.

I had Magic Lantern installed on the 5d mark III and II before RAW came around. I dont recall all these warnings about bootflags at the time. Is that something new, or would that be something that I just did not notice the last time around. If so is that what has changed about the code? So installing cannot be undone.

I dont seem to recall that being a problem in the past, however is there a build that precedes the bootflag requirements? I just want to use magic lantern for the audio control mostly.

Thanks in advance!

It really is. I wanted to make sure I had a quality product. Not something plastic and flimsy. I do some pretty heavy and mobile shooting in adverse environments so it made sense for my needs.

Hey posting here since i figured someone might be interested.



Im selling my RedrockMicro Black Ultracage Professional DSLR mount.

RedrockMicro Website

Upgraded to a Blackmagic Camera so i dont have a need for it. Its in excellent condition and im including the HDMI wireLock which is really helpful when using the DSLR with an external monitor.

15% new retail price. Redrock doesn't have much for sales if ever so I thought it was a pretty decent amount off.

Ebay Link

Let me know or message me on ebay thanks!

Well yes however it wouldn't be the same size image as a regular photo taken for pixel resolution.

Since Magic Lantern has access to the cropped sensor ability with RAW recording format. I was wondering if it would be possible to work in a way to shoot photos with a cropped sensor.

Just wondering if this is possible, been doing alot of anamorphic lately and having the ability to to have less vignetting would be nice.

Ah ok, weirder only happens occasionally not sure why hmm ill try formatting for exfat then

Build 6dfbee9 June 25th - Canon 5d Mark III - Komputerbay 1000x CF
Im getting an error with raw recording.

Happens somewhat intermittently, did not happen on first test of recording, however 2 subsequent upload times it happened.

The error was a footer mismatch. 2 extra files appeared the first time besides the raw file.

M26-1932.R00
M26-1932.R01

Removed the card uploaded the raw file, unreadable by raw2dng.

Error Message
This ain't a lv_rec RAW file

Deleted files from CF card and tried again. Same error however with this raw recording only .R00 showed up.

Figured I'd dump the error. Ill try again in a bit.

For instance, you could set a low quality recording of jpegs while shooting a movie that could be saved to a separate card like the eyefi card and possibly remote transfer to the ipad or to a server, and technically be able to then view it almost real time.

Very helpful for video, ive seen security cameras use these live thumbnails to make a "like" live web page that works on mobile phones so that you can see what the camera is seeing.

Just a thought. Got a eyefi card and thought this would be the only way to make streaming video work.
