Thank you so much, @Grognard, I really appreciate this super useful information! I will purchase two 128G

You're welcome. But keep in mind that a 128GB card is only ~119GB free spaces. And with losless compression, It could be more depending of the scene. But I'm sure 20 minutes will be OK.


Do you happen to know how many approx. minutes of 5.7k anamorphic RAW would fit on a 128GB card?

5.7k 14bits lossless is around 5.5GB per minute.
12 bits lossless is around 5.2GB per minute.
It should be more than 20 minutes by 128GB card.

I will shoot a film only in 3.5K mode and i have calculed that is around 6.2GB in 12 bits.
I have
- 2 CF 128GB
- 2 CF 64GB
- 2 CF 32GB
- 1 SD 256GB
- 2 SD 128GB

That should be enough ;)

Should be enough for a day work ;)

5DIII: To be precise there are some mode with realtime preview. Most anamorphic modes are giving a real time preview, even if distorted.

Yes. Realtime previews.... but distorted (anamorphic) or cropped (3k, 3,5k).

Thank you for the infos ! So we won’t get real time preview in the near future for 5dmkiii ? Or it is possible with external monitor or hdmi viewfinder ?

No realtime preview with hdmi device.
Maybe We will get real time preview in the futur but nobody working on it.
Try this tip : put a Phone with a director's viewfinder application beside your camera to achieve an almost perfect realtime preview of what you record ;) better than nothing...

But we have real time preview with eosm and 70D while recording 1x3 anamorphic ? right ?

Right on the Eos M and 700D (not 70d sorry) But only in 1440x1806 not with the new full anamorphic resolution (1736x 2178).

5d mark iii:  No realtime preview exept with fullhd.
No link between Sd hack (160 mHz or 240 mhz)

Maybe, do you mean continuous recording ? It's continuous without sd hack for 5.7k anamorphic.  And it's continuous in 3.5k with 160Mhz hack (don't need 240MHz).

Thank you for your reply!

In pratical when recording, we can switch between crop realtime preview and framing greyscale. Framing is usefull to check the correct frame before switching back to crop realtime preview which is stable.
If we can finetune the delay and achieve an almost realtime b&w preview for at least 5 seconds (not really need more) it will be enough for following moving subjects without a proper realtime preview.

I wonder if there way in 3.5k mode (5DIII) when recording to force framing in B&W and not switching between Black and White and color.

Maybe it could improve speed? It's the case in anamorphic, only black and White and higher framerate. In practice it's a very low resolution in black and white but almost in real time.

Thank you.

Mine sandisk 170mbs 256g doesn't work on Eos M but works on 5DIII with the new patch.... and it works with the previous patch on Eos M but not on 5D mark iii


All mode 12bit or 10bit can record more times.

Really ? I didn't notice any improvement about records times.  By the way it was already continuous in 3.5k 12bits and uhd 10 bits.

I've tried.

It works flawless!
On 5D mark iii it's very stable, but it's not a real improvement because of the 133mb/s limit.

But I've noticed something intresting. My SanDisk 256g 170mbs use to work now with the brand new sd-uhs hack while it wasn't the case before, even in 160mbs. But use to work before on Eos M with old sd_uhs but not the New one!

on EosM it's very usefull! Now we can reach continuous 3k 10bits or continuous 5k anamorphic 14 bits lossless.

thank you Bilal.

I can't get 3.5k 14bit lossless or 12bit lossless continuous
10 bit is continuous, manually stopped 4 minutes later (118mb/s)

Your CF is the issue. 12 bits is continuous and 14 bits "almost" in every situation sometimes it could stop but is rare.

  • I used the 3.5K 1:1 centered x5 preset, 14-bit lossless, 3584x1500, 25 fps...
How did you get 25 fps? With fps overdrive enable?

 That could seems strange to pay for a ML feature. But we had already asked to find a way to help ML devs! So I Will contribute for sure to thank you for what you achieved Bilal even if this feature will not be very useful for me.

I know you don't want to work on 5D3 to unblock correct framing liveview. but if you change your mind, you could ask money for the price of a new R5 ;)

thank you.

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.

« on: March 09, 2021, 06:31:03 PM »
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?
