6D + ML HDMI out question

Yes. I've used it with an Atomos recorder. It worked just fine, but it seemed we could only get it to output the ENTIRE sensor image - meaning no widescreen. So we just cut out a 16:9 piece of paper and used to as guides to put black tape on the top and bottom of the screen to show where the borders would be. Super easy.
And as a plus - the final footage will still be the whole frame, so some re-framing can still be done in editing.

What version of ML did you use that worked for this?
 
Sorry, I can't recall what version - but it was new as of this spring. So not more than 5 or 6 months old.
 
What's the resolution of the image from the HDMI out and what's the resolution of the image cropped to 16:9?
 
Here's the interesting - the editor said it cropped DOWN to 1920x1080...which I remember finding interesting because it meant we were actually getting more from the sensor than we could from in-camera recording. It seemed too good to be true - but we never took the time to go in and try to solve the puzzle of exactly what we were getting.


EDIT: The ML HDMI capture was only 1620x910. It was sized UP not down.

Thanks but sorry, it seems to me that my above questions are unanswered (resolution from the HDMI out and resolution of the images cropped to 16:9).
 
Ok Joshua - I got the exact numbers.
It's not as good as we hoped for. But we did tests and I can say for certain that this slightly smaller image still looked much better than the in-camera compressed image. When using a 6D I would always want to record to the Atomos - it killed the in-camera compression in our test shots.
Our final 16:9 video is 1620x910. Yes, a slightly lower resolution - but a better image. If you already have a 6D you can try this test yourself too. You'll be surprised at the improvements in color and in fine detail.

This is from the Magic Lantern Wiki:

Limitations

While these devices are capable of recording 1080p 422 signals, the HDMI output from the Canon HDMI is limited to 1620x1080 (3:2) while the camera is not recording.

This requires the user to crop the footage from the external recorder to 1620x910 (16:9) and then resize it to either 1280x720 (79%) or 1920x1080 (119%).

When the camera is recording, HDMI output resolution is limited to only 720x480 (effective image resolution is 640x388, which represents a stretched 3:2 frame).

Thanks.
I don't own a 6D, I own 2 x 600D (T3i), I thought of maybe purchasing 6D, but now I'm not sure.

Is it unique to 6D, or does it apply to all Canon DSLRs?
 
This is for the 6D and the 5D specifically, but the page also contained the text I copied - the first line where it says the HDMI output from CAnon HDMI is limited to..." so I suspect that will also apply to any lower models that have HDMI outputs.

I was VERY much intending to buy a 6D as I have been on shoots done with it and the results were very good. I really like Canon image quality.
However, the 6D has moire problems and is missing many useful video features so I have decided to spend a few hundred more dollars and get a Nikon D750. The cinematic image quality is similar to Canon's and the D750 has many newer features that the 6D is lacking. The HDMI output on the D750 is full HD. Plus is has TWO sd-card slots. That right there is a really big deal for me. It means SAFETY for not losing a shot from a card malfunction.
I'd still rather have a Canon C300 (who wouldn't) but I'd have to trade my car to get that.
until I can afford to move into 4K, it really looks like the Nikon D750 and D810 are the best choices for under $5,000
I am still a huge Canon fan - if I could afford new computers and high-speed media, I would get a 5DIII and shoot RAW. That is still a really really good image standard.
