Has anyone tried USB video feed while recording in the 1808x2300 anamorphic mode?

Have you tried the anamorphic 3x3 Dannes build? There is no realtime liveview in this mode. Only grayscale at perhaps half fps. I'm pretty sure HDMI output is the same view as the screen on cam.

I'm well aware HDMI has liveview, but we are talking about while using and recording with this particular build.

HDMI DOES HAVE realtime liveview when recording, the Canon-native hardware-based one (limited to 1080p), what it doesn't have currently is a replication of the Magic Lantern software-based framed preview used on the 5D3 when dealing with any crop/anamorphic modes.

Only a very small set of Canon gear actually has UVC on board: R50, R8, R10, R6 Mark II, PowerShot V10.
Canon USB inside 5D3 is not UVC but proprietary handled by PC tools like EOS Webcam Utility, EOS Utility, SparkoCam, gphoto2, etc. and some smartphone apps.

That said: You can stream via USB or HDMI. HDMI requires an HDMI capture device (most are actually UVC).
Out-of-the-box 5D3 does true FHD over HDMI. No sound.
Resolutions: 576p for USB, 1080i with HDMI.

And no audio via USB/HDMI for 5D3 (and other Digic 4 and 5 cameras).

The purpose is to get liveview in Dannes Build. Apologies when I say UVC, I mean the version of UVC which the 5D III has, which can be used vai certain camera control apps. HDMI doesn't have realtime liveview when recording in this build, but figured the USB video would be worth a shot to see what the liveview is like? Has anyone tried the USB video feed while recording in Dannes anamorphic mode? What is liveview like? I just tried to to a test on my PC through the canon apl, but my mini USB cable is broken

Hi all, keen to be more involed with this project. Btw guys, 1808x2300(2:35.1) @ 100/800 HDR - Truly gives some amazing images. Practically no aliasing due to the squeezed recording method being implemented. 1 thought, is it possible to perhaps use the USB webcam feature to get a video feed of the image, while internally recording? It then may be possible to use a mobile phone vai UVC to have a picture. Thoughts? Ill test it out tonight to check the video feed over UVC.

I did a quick test of the 6400 ISO "sparkles" and they are almost gone with 0x12 
What is the magic of this parameter? Are there any other useful values? It's a pity that the value cannot be saved, it seems to be back to 0x10 after turning off the camera

Example below, 0x10 top, 0x12 bottom:

Nothing is broken when crop mode is off, the naming is confusing.
I made this to so 1832 width was working again (was available in some older builds, without crop mode it goes to 1824 as maximum width).
Another thing I liked is that in the crop mode menu, you can set the shutter range option to 'full range'.
So when shooting 25 fps, you could use 1/25th shutter time in lowlight.
So I used the 3x3 1832x1030 crop mode for low light situations giving me 1/25th shutter time option.

For low light situations:
Not sure if you have the build with 'LV raw type' option in the debug menu ?B
By default it is set to 0x10, giving maximum dynamic range, but also gives vertical line noise in low light situations. 0x10 also makes it possible to use the high resolutions crop modes.
If you set LV raw type to 0x12 you get much more cleaner (noise wise) video.
But you can't use the high resolutions crop modes (giving corrupted frames with 0x12), but you can use the 3x3 1832x1030 crop mode.
So for ultimate low light situation use:
Crop mode 3x3 1832x1030 with shutter range option set to 'full range'. (And use 1/25th as shutter time)
In debug menu set LV raw type to 0x12.

Thanks a lot for the tips!! I didn't even notice that there was a difference in width...

I was testing a lot of thing for low light, I will test now this 0x12 value, maybe it also helps with other issues I'm having. Didn't notice the vertical lines noise but I have multicolor sparkles when using 6400 ISO and also thin vertical lines when recovering the highlights.

Camera-specific Development / Re: Porting ML to XSi (450D)

Which is actually nice.
Because it indicates cam is prepared for ML.
Now make sure to have Canon firmware 1.1.0 and not 1.0.9 installed.
If so:
Use EOScard to enable EOS_DEVELOP and BOOTDISK. Copy extracted Nightly Build content to card (wipe anything else on card before).
Insert card into cam, startup cam and wait for some time until LED calms down. Then press trashcan button to access ML menu.

Technically we agree on point 4 - MLVFS converts MLV files, in a way which is generally not noticeable   I called this "yes" because you have to install this extra thing in order to use files from ML with other software.
