currently downloaded the latest nightly ML for 60d.
60d with Lexar Professional 128gig bootable SD 400x speed
Running RAW recording for video at the default high setting. Pressed record and drop frames at 2 second into recording and recording has stopped.
Do you need a model number of camera? - let me know what other details to share, but the 60d raw does not work for me.
I also tried ignoring the dropframes and the results did record but continued to drop frames.
