Thanks for the update reddeercity - encouraging stats and great to hear there's still activity for the Digic4 cam. I'd like to help out down the line once I'm familiar with the camera and ML (only had it a couple of weeks!). I am an OSX user and programmer - not C but have compiled C apps.

Right now I'm trying to determine what theexpected behaviour of crop_rec on the 550D - so I can establish whether it should be working or not in any ML builds. I'm currently running your 1 Dec 10/12bit build for which I assume crop_rec is not meant to be functional? The module is enabled but the setting is dimmed under all the combinations of video and bit-depth settings I tried. Am I right in thinking that, to invoke, crop mode, I just need to have the module enabled, set any native 720/1080p mode and push Zoom in LV once before starting to record? When I do this with this build the camera chokes almost immediately on record start and needs a reboot.

From crash log:
ASSERT: dwDeadLine != 0xFFFFFFFF
at LVState.c:5842, task LiveViewMgr
lv:1 mode:20

Magic Lantern version : Nightly.2016Dec01.550D109


Is there a recent build you can recommend which does have working crop_rec for the 550D (14bit). I'd like to see it working so in time I can find a way to help with getting 10/12bit crop_rec support available for this camera.

Hello,

I recently picked up a 550D and having some fun with ML. Currently am able to get continuous RAW 1280x326 2.35:1 12 bit @24fps cropped without sound using mlv_rec. As I understand it, sound does not work with any overridden frame rate settings - correct? This is using the last compressed bit build I can find for the 550D from Jan 14th.

No luck yet with 10 bit recording. Just a quick thanks to all who've developed (are developing) ML - I'm hooked! Also to echo Keith Wu's post from a few days ago - there are still a few of us 550D users out there keen to test some more recent builds if any of the gurus are up to it.

Finally i can't really figure out how to compile and i noticed nothing new has been put out for the 550D.
So i was just wondering if someone could compile a new one (unless you guys stopped working on it)
because i would love to keep testing builds and giving feedback!
