working 1080p more than 37fps mode with working preview would be awesome enough to buy one again.

Any ML build wil do your job. Set to 1080p mode n increase the fps overide. I think it can go upto atleast 40fps

Actually, tested fps override and above 36fps seems to cause corruption. Therefore I added a 38fps preset just now. Think a1ex had around 40fps working at some point or close to it.

@Danne: what is the current best mode available to shoot in 1080p with 5Dm3? Does the unsqueezed 48p with compression still have a gray or choppy preview? Thank you
PS: I no longer have 5D to test myself, but working 1080p more than 37fps mode with working preview would be awesome enough to buy one again.

5D III currently by Danne's Build:

1920x1080 45fps
1920x1050 48fps
1920x960 50fps
1920x804 60fps

Full working preview ;)

Edit: all is 3x3 binning and it's streched.

1050p 48fps
Full working preview ;)

Wow, this sounds amazing and should be given more attention. The last time I was shooting with 5D, there's been only build by a1ex with 48p (3x3 binning), but the preview was gray/choppy or squeezed/incorrect framing. Any leads on how to get this mode working? Last time I checked, I couldn't get anything with full-sensor working from these experiments, so I thought Danny's work is related to crop modes.
Thank you,

Danne

Nothing changed. It´s still stretched preview. We need to be realistic here. It still works very well and is totally usable for me and most users. If you can´t work with the shortcomings please do not rebuy the 5D3.

Thank you. I've never said I want to rebuy, just asked what the updates are, as it is not that easy to keep up with the forum.
The stretched preview wouldn't be that big of an issue, but the framing is not accurate for 16:9 as far as I remember. So not that easy to use in the real world.

Is there anything new besides 38fps preset that you need us to test over yesterday build ?

Changelog?

Hello I wanted to comment that with the 5d3 1.2.3 full anamorphic 3240x1920 av11, iso100, 1/64 in sunny shots, with both cards sandisk extreme pro 128 gb 95mbs + lexar professional 128 gb 1066x 166mhz, 14bits 6 minutes 100+ 70 mbs 15,003 fps , on your latest compilation, could it be possible to zoom to 16 or 17 fps like the eos m for better optical flow?
Thank you.
