Post Deflicker XMP file not being read by ACR anymore .
« on: December 12, 2013, 05:53:31 AM »
i have been updating with the nightly builds for the last week. Suddenly my XMP files are not being read by camera raw. I formatted my cards and re-installed the latest build of Magic Lantern , as i thought it would be the solution to this problem but it wasnt. I tried again and again and still ACR wont read my xmp files, which is very weird because last month i was doing a couple timelapses and it worked no problem. Is this a issue again in the newer builds? I have read the thread where it use to be a issue in the beginning stages back in May by setting your color space to sRGB instead of AdobeRGB as a workaround. But this whole time i have been shooting on Adobe RGB and havent had a problem with a timelapse until now. Can someone please point me into the right direction or let me know if theyre having the same problem?

Just to make sure these are my settings just like the tutorial front page.

Autto Ettr = always on (default settings)
Post Deflicker = XMP (default settings)
Intervelometer = 15s

My camera is in Maunal Mode, custom WB, and color space Adobe RGB



this is what i used to get

Which camera are you using, and what was the last build that worked?

Canon 5d mark 3

I dont really remember what last build worked because for the last month i would update the recent nightly build every week. but i did re install a build from october and it still isnt working correctly. I did switch my color space to sRGB and it worked but not properly like Adobe RGB use to.

1: Make sure your camera time is not ahead of the computer time you will be using.

2: If the name of your CR2 file does not agree with the xmp, change the XMP always.  In this manner the xmp will be modified after the CR2.  If you do it the other way ACR will not read the files.  Always the CR2 Modified Time Stamp mus be before the xml Modified Time Stamp.

Look at the time stamps on the files. Are the CR2s ahead of the XMPs?

Ive just realized that theyre are getting named differently

for example

photo
_33A0001.CR2
xmp
333A0001.CR2

Whats the way to make sure they get named the same ?

Rename them.

If anyone would like to fix it in ML source code:
1) find PROP_COLOR_SPACE (from my notes it's 02060000, but not tested)
2) in fileprefix.c, get_file_prefix, replace the first character with underscore if color space is adobe RGB. Don't modify file_prefix; create a static copy instead.
