Solved drift issue with 5DM2 and Zoom H4n with Pluraleyes sync software per very helpful 25 hour post found here on DV Info.

25 Hour Day: DSLR Dual-System Audio: The 99.9% Solution (http://brucesharpe.blogspot.com/2009/06/dslr-dual-system-audio-999-solution.html)

Issue now is - 5D footage is at 30 fps and I would like to shoot a second camera, my Sony EX1 and drop in into the FCP timeline as well - however the EX1 is running at 29.97 fps and I am assuming this would be an issue,

Wondering what a solution would be so that all 3 devices would sync and play nice together in FCP?

thanks in advance :)

Someone will surely correct me if I'm mistaken, but I believe with the previous Update for the 5DM2, we're now running 29.97.

The latest firmware makes the 5D work at 29.97fps and cineform converts the files from older firmware updates to work with other cameras. If you haven't done the firmware update, you should carefully follow the procedures and get this done. If you have trouble editing your files, look into neoscene from cineform.

Ah, thanks gentlemen, will update right away :)

Cheers
