Now check if it works without sync issues. As far as I know, it misses some frames.

Is it recommended to shoot a certain way, the flicker seems way to far apart to make work, mostly the dark iso and real fast flickers bright every 1 or 2 sec, plays back the same way I see it during recording, its nice a constant fast flicker like in the videos I saw on vimeo

and its a random flicker to, not constant.

is it best i shoot something and up the raw footage so u can get a better idear

The same thing happens with 5D2.

You may play with MovRecState events (in hdr.c), maybe you can figure it out.

the way it works is i records for 6 frames at normal iso and on frame 7 it changes to low or high iso, then 6 frames play normal, then on frame 7 it the opposite iso of the last changed iso, this was at 24fps, exposure override active using iso 800, and setting the EV4.

I know how to fix it in post, but its really a pain in the butt and even more work to do, which isnt a good idea (my post workflow involves a lot of process, including converting to 24p. If I get 24p but for that I need all the tweaks before I can use the file properly, then I've done nothing. Just changed one process for the other, improving nothing in the worklow). It woudl be awesome if it was done in camera, as it normally do.

What about when Coutts did manage to change the playback rate and we thought it was frame rate?
That fix couldnt be used in this case? If so, then frame rate chaging would be complete, aside only the audio sync.

He tried it, but didn't really work (don't remember the exact issue, probably only worked in 1080p).
