Thank you Bilal, you are a wizard! Realtime preview without global draw it's crasy. You gave a big boost with sd overclock and now realtime preview!
Will it be possible to have good ratio for 1×3 mode too? Porting on EOS m should be easy but on 5diii and 5dii more work to do.

Nice shots, beautiful colours, beautiful Mountain !
How many seconds did you get before stop?

Is it first april of this year?

Amazing work!

Very cinematic footages!.
Which resolution can you reach by shooting in 2.20 ratio? More 3k than 3,5k, i guess.

Global draw needs extra resources, so it slow down the maximum writespeed.
maximum speed with Cardspanning and overclocking for now is BTW. 131MB/s (Nobody knows why).

True for UHD mode but you can reach higher writespeed in 4K half FPS or 5'7k full liveview (170 MB/S -100 CF +70 SD).

Hi all,


l did a little comparative test of the sharpness between the 3k, 3.5k UHD, 4K 12.5FPs, 5.7k 7fps, 5k anamorphic, fullhd, fullhd h264 modes. I shot with an EF L 24-105 canon Lens at F.14 compensating the cropfactor. All were upscalled or downscalled in 4k (true 4096) which I take as a reference resolution. We can see that the sharpness is better in 1: 1 mode than in anamorphic mode, but the difference is minimal. The difference between UHD and 3.5k is not really obvious. The FullHD is very mushy and the h264 ... let's not even talk about it;) In conclusion, the most interesting modes are
- the anamorphic mode because there is no crop and a real-time feedback, the loss of sharpness compared to 3.5k is not so bad. it looks very well in 4k.
- 3.5k mode, the crop factor is only 1.6 and there is still usable feedback (zoom x5). But the ratio is wider than the 2.39. If you want more vertical resolution you have to go to 3k.

- full HD, it's ugly but it works so well!

Thank you Danne for your  incredible  build!

Danne. Is it possible to make Fps overdrive usable in 5k anamorphic mode juste like the EOS M does?
Thank You.

Nice footage. 5k anamorphic is undisputable the most efficient preset of them all if filming 24 or 25fps. What lens was used?

Thanks. I used Canon EF 24-105 L.
Around F.16 a little too closed at my taste.
I had forgotten my neutral filter but the clouds saved me.

Hi. I'm a long time user but it's my first post here.

I've tried Danne's last build with sd_uhs module and works perfectly on my lexar 256go  633x. A relatively cheap card.
I can reach more than 40 MBs write speed (with peaks at 50mbs).

With card spanning on, in UHD mode, write speed is around 120mbs (80 mbs CF +40 mbs SD)

I'm also able to record continue 1920x804 14bits lossless on Sd card only.

I also tried 5k anamorphic and it works perfectly. No crop factor (!) almost realtime liveview and very good quality. sd_uhs is not necessary but could be usefull on very contrasted scene.
I made a short video with this mode.

I will made a more complexe short film with this mode soon.


Thank You Danne (and others A1ex, Lila.. ) for your work.
