For some reason my modules do not always get compiled when something new gets updated. Tested "as is" with the camera settings as have been saved by g3goo. Great results all audio is pretty well matched. I get better alignment if I move the audio forward by 1 frame. Changed setting to Preview=Hacked and also enabled Mrmory Hack, and card spanning ON. Tested with Card spanning ON at 1920x1080 at 29.97 fps and the audio matched again! Tested with Card spanning ON cropped video at 1920x1080 at 29.97 and had to slide audio forward by many frames and then to shrink the audio a bit. After that it matched. Tested with Card spanning ON 60 fps at 1600x560 the audio could not be synched by trimming or stretching or sliding, the audio was there but could not align. Tested with Card spanning ON Tested 50 fps at 1856x650 the audio could not be synched by trimming or stretching or sliding, the audio was there but could not align. For Post processing I always used MLVBrowseSharp and exported to DNG (with green cast) then I imported the dng and wav file to Vegas. Noticed that the green cast on dng is not due to BlackLevels. It appears that Color Temperature and Tint information is missing. As soon as I set in ACR Temperature to 5000 and tint to 0 the colors seem appropriate. ------------quote end---- src: https://www.magiclantern.fm/forum/index.php?topic=7122.1000 I also fished out link to specialized open-source player from this thread https://bitbucket.org/baldand/mlrawviewer/src/e7abaaf4cf9b?at=master "About MlRawViewer is a cross-platform viewer for raw video files produced by the Magic Lantern add-on software for Canon DSLR cameras.
