Homebrew firmware for the 5D Mark 2

Tramm Hudson · May 24th, 2009, 04:50 PM

I've posted a short video of my on-screen audio meters running on the 5D Mark 2. It is the most boring 45 second video you will ever see, but it has such promise!

Congratulations! That's a big step forward.

It ain't boring anyway and no how... This is great news and a super effort. I have been watching your progress, and to me it is like reading a good mystery novel. Something new at every turn. Please keep posting your progress there !!!

Um..... WOW!
This is brilliant. Hope Canon notices!

Excellent suggestion. Done!

Amazing to see this stuff! Thank you for what you are attempting!

I have to put in a request if you are taking any--

Live HDMI output--If the full 1080 can be output (without overlays) while recording, that would be a big deal. If not, it would still be great if the live output's graphic overlays can be disabled and video set to full screen and hopefully the timer on locked settings can be disabled.

It's not that I'm totally unhappy with the 5D2's compression, but I would love to be able to mate it with the nanoFlash in the future.

Happy hacking!

Great suggestion, Barlow. Full HD, even at reduced framerate, would be fantastic for live focus. If at the full framerate, it would be useful in the studio and for pulling keys. Even if some masking exists, it's still useful if you can get 2.35:1 or 2:1 aspect ratios.

Live histogram - and zebras - would be amazing too, but we're getting ahead of ourselves.

Being able to adjust the gain and having an active headphone output will be excellent improvements!

The video has been updated with the now flicker-free meters and full-time 16:9 crop marks.

Looking good Tramm! Looking really good!

Congrats on you field promotion to Wizard Status

Dan Chung · May 25th, 2009, 11:13 PM

Tramm,

Great work, I hope Canon takes note. Have you thought about trying to hack the magnification function to work during recording? would be pretty tough I guess.

Also how about switching the shutter button and the set button, is that possible?

Tramm:

Really impressive work there! The update with the higher rate and less flicker looks pretty usable.

I know that everyone wants everything from you but it seems that after all of your great audio work, the next logical function would be to make the exposure lock stay on as long as the camera is powered up. If you can obtain the exposure ISO and shutter speed desired, the ability to hold it indefinitely would be amazing and I would think would not be very hard for you to program?

Let us know your thoughts on if enabling this function would be very difficult.

Thanks,

Dan

Dan,

Good point, second that. And thinking about it, what about having it maintain exposure lock after the end of a recording.

Dan,

I third the motion.

Dan and Dan,

Now I know what the 'D' in 5DmkII stands for, its clearly Dan. Nobody else but Dans should be allowed to use one!
