Magic Lantern is great, so is Tragic Lantern. With T3i/600D and some versions of Tragic Lantern it's possible to shoot 16Gb files, which is great. Alas, to my experience, TL with 16Gb files works fine, as long as you don't record audio with the video. Though I have external audio recorder (actually 2, Tascam DR-40 and Tascam DR-60D), I need audio in the camera for sync in editing. I edit myself my movies and not being an experienced editor, I need the audio in the camera. It seems to me that the audio issue with TL and 16Gb files is inherent in TL, since no matter what settings I put in TL, when recording also audio, recording stops after few seconds. Did anyone manage to have 16Gb files with audio in camera?
