EOS M vs 5D Mark III

5D III is far better but 1080p is  bad compared to anamorphic or crop mode even on EOS M

@bilal and Danne

I've noticed that 5k anamorphic mode works with fps overdrive enabled (24fps) but not 5kfrtp.
How to explain that ?

Is it the key to also make this work on 5d3?

-I didn't test it with CF card yet (with Card spanning), waiting the CF to arrive . .

You won't get anything from this post, further research is required . . but it's cool to showcase how 240 MHz preset would perform when it works.

Great. Wait and see.
Does it mean you finally got a 5diii?

Magic lantern evolue toujours! Par contre les traductions française non. Il faut donc utiliser les versions en anglais ou alors faire les traductions soit même car je crains que personne ne s'en occupe.

Hi all,

I just drop here the link to watch this long film shot only with a 5d mark iii.

It's no budget film with no professionnal actors.
Not a Masterpiece I know but a long film shot with 5d Mark iii is rare.

Or maybe this?;topicseen#msg233989

This device needs a HDMI input.
In my case, I use the inbuilt camera of the smartphone to provide me a decent preview.

 Hi all,

We know that the main issue with 1:1 modes is the cropped preview. There is a stuff we can use to help when shooting especially moving shots: a director's viewfinder application on your smartphone.

It's easy by setting the smartphone near the camera to achieve a very similar liveview.   

of course it will be not perfect due to the perspective. however
It will be usefull to follow a subject or whatever.

we can also use another camera but we need two cameras and two lenses !

"The only indicator available is total GB used on the card, in the upper righthand corner BUT it DOES NOT UPDATE unless the whole camera is rebooted.This is very problematic for film work."

Buy a larger size CF and reboot the camera to check remaning free GB when you suspect almost full card.

What exactly the resolution is for 3.5K, the aspect ratio and bit rate that works best? How long can you record for before it crashes and you need to take out the battery to start going again?

With the latest Danne's Build. It's continuous in 12 bits, 2.39 or 2.35 in realtime crop preview, card spanning, and Sd hack enable (better results with sandisk 170mbs or 95 mbs).
pretty stable, no crash for me.

14 bits and a little higher vertical resolution should work too.

Nice but a little too soft at my taste.

Why don't you use 3,5k mode? Work as well and there is less crop factor (super35  look).

Nice! Very natural look.
Which lens did you used?

Awesome !
Very nice shots of the city. Good job.

3,5 K(3584x1300) Vs anamorphic (1920*2340).

I also made  tests, i think than 5k anamorphic is really much better than full hd upscaled and very close to 1:1 mode. Not true, mathematically 5k anamorphic has more pixels than 3k at the same ratio (2:46) 1920x2340 =4 492  800 pixels, 3072x1248 = 3 833 856 pixels. It's true that 1:1 is sharper but it's not so easy to see a difference in detail even in 3,5k.

I agree with IDA_ML, to be more scientifique, close shoot is not the best choice because of the variation of depth of field.
A landscape should be a better choice.

Let's buy a 5Diii to theBilalFakhouri! The ML communauty wants to help all developpers (especially the realtime previous which is the holy grail :D) we're just waiting for a solution.

For EOS M 4.5K anamorphic has a crop of ~1.18x.

I added APSC crop factor x1,6

Loved it!

Technical note: some scenes were a bit too over exposed, didn’t look like they were overexposed in camera, just the general exposure pushed too much. The grade matches across the film, but exposure is jumping a bit (in some scenes, match the scenes and mix the sound and you‘ll have a great film for the festivals, if that is your thing.

Also 5D3 raw upscales very nicely with the right algorithm.

Good luck.

Thank you for your feedback! yep ... postproduction needed.
I know there is some jumps in exposure, i have to improve the colour editing, i pasted the attributs and it doesn't fit very well on each shot and i balanced quickly.
but there is no overexposed.
otherwise not enough light on some shots but it was a choice to use no equipement. My next short film will be shoot in 5k anamorphic with more technic!

Wich algorithm is the best for upscaling do you think ?

Thank you!

Best regards

Yes it will be great to add these two. I Nevers use 16/9.

Yes. 5k anamorphic (crop~ x2).

Here is a short film I made on 5Diii with classic fullhd raw. It was shot as a documentary with almost only handly shots and a microphone fixed on the camera...
Not the best quality compared to new 3,5k mode ! But full HD still worth.

French, dutch, english and welsh langage with english subtitles.

Ps: sound still need mixing

If the Black Bar limit appears when we attempt to process more than 2048 RAW data width in LiveView. Maybe we could "move" this black bar to show the other side of the frame and then switch between these two previews.

It works, thank you Bilal. But it's difficult to keep concentration on the screen with the stuck frame bug or the white noise in the bottom.
I've found a little trick to keep the black bar in the bottom screen by pressing menu button untile the black screen appear then quickly toggle to framing mode by pressing focus button.

We can also toggle in photo mode and quickly go back in video mode.

I also notticed that if we reduce resolution, in 2,5k mode, the preview is still the same and then larger than the correct frame. It's better than the otherwise!

UHD 2.39 is "only" 6.170 880 pixels (3840x1607) less than in this case : 6.200 320 pixels (3584x1730)

It means you have fixed the liveview in 1x3... :o
What a great periode for ML!

Thank you Danne! I look forward to test the new build.
With next uncropped realtime preview this old camera will become a brand new 4k camera! ;)
