Raw Video / Re: 550D raw video recording port official thread

Hello !
So I've tried your latest version mk11174, and I may have found a way to use the actual RAW rec module, a way that suits my needs...
I'm not really pleased by the 960x408 resolution, to my mind we are losing too much sharpness.
That's why I go 1120x374 (3:1 aspect ratio, Yep, I know that's an ultra wide ratio  ...) and It manages to work without frame skipping !
But you have to set your FPS override to 23 fps (prefer "exact" in the FPS override settings, It seems to run better...).
The difference between 24 and 23 is hardly discernible.

Anyways, when you scale the RAW image to 1920 the results are pretty good in terms of sharpness, and you have control over the RAW possibility ! The "landscape" still miss a bit of sharpness but at least you gain the benefits of the huge dynamic range !

Here are some screenshots

Have a nice day !

What build you're using?

I tried to record 1120x374 @ 23 fps, but I only got 62 frames..

BTW 960x408 @ 23.976 fps seems to be very stable, I just recorded almost 7GB(~11 000 frames) file.

I'm using Sandisk Extreme 45MB/s card.
