To whom it might concern: Bilal (he of the 650D/700D fame) had expressed his interest in working on the 70D build, but lack the camera itself: https://www.magiclantern.fm/forum/index.php?topic=25784.msg236046#msg236046

FYI: 70D and dual iso (video) are a NO GO. I even documented it in source code. Dealbreaker ist the dualpixel AF

Oh, cr@p. But thanks for the heads-up (not no mention the original port)!

Oh sh!t, I could find these comments in dual_iso.c for 70D:

Code: [Select]
        /* WE DO NOT SEEM TO BE ABLE TO USE DUAL ISO IN MOVIE MODE */
        /* MORE CONFUSING IS THAT WE ARE INDEED ABLE TO USE */
        /* CMOS[0] OR CMOS[3]. BOTH SEEM TO WORK WELL IN PHOTO MODE */
        /* FOR NOW LET US OPT FOR CMOS[0] BUT THE QUESTION IS: */
        /* COULD WE TAKE ADVANTAGE OF USING BOTH AT THE SAME TIME (TRIPLE ISO)? */

Is there any further details why it won't work in movie mode? it just doesn't work; no sign of alternated ISO in movie mode?

Heavy flickering appearing with flipflopping colors. Canon calls it themselves "Dual Pixel CMOS AF". So it is interfering! Back then had some heavy talk with a1ex about this but wasn't able to find a solution although spending much time.
