Changing the keyframes (including angle change) in LR4 & CRTL-S
worked on> LRT Reload/AutoTransition/Deflicker/XMP sequence
back to LR4; unlock keyframes filter > select all frames & load metafiles
now LR4 changes back to old settings..
any idea why?

Please double check your workflow, normally there is something wrong with it. If nothing helps send me the logfile: info/log to support (at) lrtimelapse (dot) com
