No Flash-Signal on 5D MK II while shooting video? Does Magic Lantern help?

[Karmaschinken]

Hello, I want to shoot video and meanwhile the recording runs shoot stills with studio flashes, but I don´t get a flash signal out of the cam while in video recording mode. While being in Liveview without recording, flash signal are delivered. Why is this and can Magic Lantern help me with it?

Thanks a lot!

I still need this feature on a 5DII, 5DIII or better a Canon that shoots movie faster than 60fps, if available. After having an odyssee trying to find out how to trigger flashes at a RED EPIC camera, I return here to maybe ask for a solution? Is there any chande to get a fash trigger signal while shooting movie? I know, this is very special. But I appreciate that very much. Thanks a lot!

Maybe I should put this thread into the feature resquests?
