Hey just got the newest build but zebras are offset by about an inch on the screen and also the screenshot feature doesn't seem to work as it counts down to 5 and doesn't count down anymore.

I just DL'ed the 500D alpha ML firmware today and use the intervalometer. I set it to shoot every 1 second. It works, but stopped at 25 shots both times that I tried.

I have an workaround for you until a proper fix goes in place: shoot in AV mode (any mode other than manual i believe will work). I personally tried AV and i was able to take over 140 pictures before i stopped the intervalometer. When i tried the same thing in M mode it stops after ~ 20 pictures.

any way you can take a picture with your phone camera or something else and post it here?. i've been playing with zebras on and off and i haven't seen anything wrong, at least nothing as 1 inch which should really jump at me. I don't doubt that you are right, i just want to see it and maybe figure out how to reproduce the problem

I hope this helps at least a little. I took it with my Kinect so it was a little hard getting it in focus :)

Nice that fixed it and now it is wonderful. Zebra delay seems to be at about 1 second.

yap, that sounds about right. is not the fastest thing ever, but it works really nice...i like it a lot.

i have a theory why is working now (although i have no clue why it did work for me and RoaldFre before):

what i did in the last build is to change the vram address to one that has a 720x424 image while the previous build was using an address that has a 720x624 image. now if you look at the bottom of your lcd you have a dark band (i bet about 480-424 pixels) where there's no image and it's used by canon as display area. if you use DISP button you will see that are being populated. ML is also populating this are with its own info (ISO, apperture, shutter, lens data...etc).

if my theory is true than the vram address that we should be using is the one that has the 720x424 image. I would really appreciate if anybody else that tries this build will post with their own experience. On my camera i can see blue zebra on that bottom black strip which if the theory is proven right i believe is a bug.

The 550D has a different screen layout and image can be displayed full-screen (without any bars). You may want to let y go to 424 only in the zebra loop (if I understood well what's happening).

whoa.. i can see the developers are hard at work! Great job guys, btw what is the current condition for the ISO, Shutter and Aperture manual controls? I'm hoping to be able to use this for a upcoming video shoot.
