I'm starting to classify my documentary filmed with eosm 4.5k 2.35: 1 in davinci, setting the project in 4k dci but the closest option is 2.39, how do you work? do you leave the black bands and then cut them on delivery?

Interesting. Have not looked into post production issues. Maybe I should include a 2.39:1 preset in there s well as it seems what is used for cinema these days rather than 2.35:1.

Your issue, could you describe more in detail, maybe upload a few screen grabs?

may be a strange idea but anyone thought about shooting with two Eos m at the same time. Wouldn't you get 5 k for the cost of the two cameras which would be around 300 dollars these days.

Mmhhhh... That reminded me a friend who said "If you need a 3D printer, why don't you just use two 2D printers together so you get a 4D print and then get rid of 1D?"
Jokes aside, how do you imagine this would be feasible?

Do it as a panorama, always wanted to try that. It's a very good idea.

Or shoot 2000x2000 and then when you combine it will be 4000x2000

Why 2 ? Cinerama did it with 3 cameras for widescreen

You should find a way to arrange three cameras similarly to this

Maybe three eos M with 22/2 in vertical configuration could do the trick

My thoughts as well. You could connect 2 by the tripod mount and shoot vertically

I don't think this would be optimal. You will have some vignetting and distortion in the corners/edges. You would need to correct these in post, otherwise you will have darker lines/blobs in the middle of your video (like in the example video above) and also the stretched/distorted corners will meet in the middle of your frame and you will get a weird looking picture. Also, how about sharpness decrease in the corners? For this reason when making panoramas you always overlap shots by about 30%, maybe this won't be a problem with low res videos..

Now we're talkin'.

Gosh, and I thought my 3 were an excess. How did you come to own 4?!

All in all, this is a neat idea, I need to try it out.. I imagine a custom mounting plate should be used - cameras either looking away or towards each other.

@berechiah Sounds good! Can you give your settings?

So sorry I didn't see this
I'll write the full list of info on here later for you

But there is a guy on YouTube called zeek
Just type "eos m zeek" and he has some seriously good videos on all this info
I'd be lost without his help also its extremely informative

Make sure to make room for an M2 and an M50 -- and get a few of those shutter-bugged lenses too.

You miss the silver version dfort ;)

New version:
https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

- Added the more up to date cinema ratio 2.39:1 into the preset menu in crop mode sub menu. Works on all presets:
- Updated the lua cinema script to enter 4K anamorphic rewired 2.39:1 mode as starting point

2.39:1

My first EOSM was silver.



Did a lot of experiments on that camera.

I've been looking through the forums but can anyone tell me if turning off sound and kill global draw will result in longer recording times? does setting to greyscale have any effect?

From my experiments turning off sound and killing global draw will definitely help to either make a recording a bit longer or if it is borderline continuous become one. Not sure what you mean by greyscale, if you mean setting preview to Frozen LV, it will help a bit as well, but not as much as turning LV off altogether.

From my experiments, the biggest improvement comes from changing bitrate from 14 bit to 12 bit - improvement of almost 11% in terms of reducing generated data. Strangely, going from 12 bit to 10 bit reduces data by only 7.5% - still a good improvement though. Turning off sound and killing global draw has much smaller effect than reducing bitrate. I never measured it but I would say maybe 2-3%.

Kill global draw will have a bigger impact than turning off wav. Tested grayscale preview but couldn't see any speed difference. Frozen liveview will have a big impact, even if using halfshutter to get framing preview too.
Workaround when using 10bit for example in crop mode sub menu is doing the same as when reducing to 12 or 11 bits in RAW video section. Not as sophisticated but works.

Thanks. I am familiar with Zeek’s videos. Mcmrewire still gives me too much aliasing/moire. Maybe it’s the lenses I’m using (ef-m lenses) or something in the settings. But I have a feeling it’s the lenses. When I shoot in moviecrop mode it’s much better, but the crop factor..
