Hi! I'm getting flickering highlights when exporting a dual iso mlv as an Apple ProRes video. I don't have this issue when exporting the video as a DNG sequence. Actually, it's not a "proper" flicker, it's more an alternate dual iso preview / dual iso correct output. I'll attach an image showing a problematic frame.

Thanks. Did you try working with RAW footage (cDNG) directly in DVR? If so, what made you choose the other route?

I tried just now. I can confirm that exporting a cDNG sequence from MLV App doesn't produce any highlight flicker. There is no particular reason why I decided to use ProRes4444, I guess I'm just more familiar with that codec. Anyway cDNG seems much better..

Nothing special, really, just some slight correction in mlv app (particularly rising shadow brightness and adding 30 or 40 sharpen) then I exported everything as ProRes4444 and edited the video in Resolve (with some little more shadow brightening).

The only thing that didn't work were the highlights in the dual iso shots which were flickering a lot. Do you know what could cause this?

Hi! I made this video to test Magic Lantern raw video capabilities on my 5D Mark III and to test a little set of soviet lenses I gathered. Everything is shot in 5.7k mode. The lenses I've used are:

- Mir-24M (KMZ, 1986)
- Helios-44M (KMZ, 1978)
- Jupiter-9 (GOMZ, 1992)

So: patience please , BTW do you still have your EOS M? if yes, you might get some exciting news for it next month

Nope! I've sold it! Right now I'm a happy 5d3 only user! Don't let me regret it!

So basiclly I will have a EOS M2 and 70D to work on sooner or later
EOS M2 is more likely very similar to 100D, I will look into it later, also if there was a EOS M2 tester, that would helpful too.

What about us forgotten 5d3 users? Will there be good news also for us? 

A beautiful light this morning and the beauty of dual ISO. Processed with MLVApp of course 

Very beautiful!

It's no problem, it's a feature: you enabled Zebra function. Press Z to toggle it (or menu->view->show zebras). Blue is cut shadow, Red is cut highlight. You also see marker(s) in histogram.

Silly me!

[MLV App Clip 1]

We need files and more info like print screens or similar. Very vague now.

You're right! Here are two clips (one 5.7k and the other 3.5k) opened in MLV App and in MLV Producer. As you can see the underexposed parts of the image in MLV App are shown like in a "false color" mode. In MLV Producer are shown correctly.

Here you can download the first clip: https://we.tl/t-dO0M2bTyrX

I'm having a weird problem in MLVApp on some clips taken with my 5d3. The underexposed parts of the image are blue like if it was a false color view. Lifting the shadows solves the problem. In other apps, like MLV Producer, the problem doesn't show..

Question for Vastunghia: are the 3.5k liveview and the external monitor image the same or the monitor is even more cropped? What monitor are you using?

 

Bottom lines of movie screen should tell you required bandwidth.

Of course they do, I just wanted to know what's the experience of someone with cards faster than mine, if he/she can record with uncompressed bit depths and if his/her liveview works.

So, today I had some time to test my "new" 5d3, let's start saying that I'm very much pleased with the quality and the responsiveness of the camera. I only have one question. Everytime I selected any one of the non compressed bit depths in the raw sub menu the liveview froze and I could record only 1 or 2 seconds before the camera stopped. This behaviour happened even with sound recording turned off and every hack and sd overclock turned on, and it was the same with 10, 12 or 14 bit. The "lossless" bith depths, instead, they worked flawlessly and the liveview is very fast even at 3.5k. So, my question is: are my cards too slow for the non compressed bit depths or is it just like that at this development stage?

Yes, "Card Spanning" was always on in every test.

If you don't have two cards in the camera there can be no spanning

Sure but I was expecting a greyed out "spanning" option but there isn't in the menu

Maybe a silly question: why I do not have the "Card Spanning" option? Is it because I don't have a CF card or the latest Danne build is just like that?

Yes, I confused read and write speeds, sorry..

I have a problem with a bad pixel. It gets eliminated with "auto" bad pixels fix but are there some bad pixels maps for the 5d3? Or how can I create one?

Nevermind, I've found out how to do it

Answered. And your Samsung is labeled R160/W130, not W160.

I have a 256gb Samsung Pro Plus (160mbps in writing) SD card which I was using on my previous system, a Canon Eos M, and which now I intend to use on my 5d3. Which CF card do you suggest to use with this specific SD?

Any advice for the SD and CF cards to use with the 5d Mark III? Which model is better to work with Magic Lantern?

hello everyone, like mattia i bought a 5d mark iii, actually i got it today and i have already tried danne's release with anamorphic at 5.7k. I use a 64gb cf komputer bay 1066x and a 128gb lexar 1667x sd. the quality of the files is exceptional... i wanted to thank danne and everyone for the valuable advice i found on the forum. given my inexperience in video with ml, until now I had only used it for photography with a 6D, I didn't know if there were any differences in writing speed by installing the release in the cf compared to the sd. where did you install it? in any case I did some tests and I got more or less the same speeds for a total of 153mbps with memory overclock at 240hz regardless of whether ml was on cf or sd. In ogni caso, ciao Mattia! Fa piacere ritrovare qualche italiano anche qui!

È sempre bello! Dovremmo fare un thread tipo "Magic Lantern Italy"! Hahahah

Anyway.. I was just asking myself which are the best (and the fastest) sd and cf models for the 5d mark III.. Are there some "official" Magic Lantern suggested models?

Yeah, anyway @Mattia, the rule is: if you don't need HDMI, go for 1.1.3. Look for downgrade instructions.

Yes, 1.1.3 version is the best option for now since I don't have an external monitor. I've already downloaded the Canon firmware and watched a video about downgrade, it's pretty simple.
Grazie ancora!

Yes it is correct. And yes you can follow action. Only thing you cannot do is adjust focus. For that you will need an external monitor IMO.

I would be happy to make a video for you showing you how LV works, but unfortunately I don't think I will have the time — at least before the week-end. You may find something on this forum or over YT however.

Thanks again for your answer! Anyway I bought a 5d Mark III today, I've found quite an occasion! Around 10k shutter actuations, not even a small scratch, for 550€! Not bad at all! I'll receive it next tuesday and I can't wait to try it!

By the way this camera has a firmware version 1.2.1, should I upgrade it to some particular version before installing Magic Lantern? And why on Danne's repository there are two distinct builds?

I use 14-bit 3.5K 2.39:1 all the time and the only problem I face is that I cannot always accurately ETTR (sometimes I have to stop down 1/3 to max 1 EV in order to get continuous rec). This is also an advantage though, as I'm pretty confident that rec. will stop if I inadvertently were clipping highlights

3.3K is continuous in all situations for me.

For UHD (which natively is 2.61:1 btw) I think you will have to switch to 12 bit, however I didn't test it much, preview is completely broken at this time.

They are 1x1 crop modes, so the math is pretty simple here. Just divide full sensor pixel width count by rec. resolution. I recall that 3.5K is perfectly 1.6x — which makes this mode fine even with APS-C lenses

Absolutely.

LV is not exciting, but Bilal is working on it! So fingers crossed Currently I use fast grey preview on LCD just to have an idea of framing and an external HDMI monitor for focusing. Unfortunately HDMI out is equivalent to the x5 cropped zoom area, so it is impossible to focus subjects on the right or the left of the frame.

My cards:

SD: SanDisk 128 GB Extreme PRO 95 MB/s, Class 10, U3, V30
CF: Lexar 256GB 1066x 160 MB/s UDMA 7 VPG-65

HTH

Thanks for all your precious info! You've been really kind to clarify all that! I would only like to understand a little more about the liveview. Does it offer correct framing, even if slow? And.. How much slow is it? Could I follow some actor walking in a room, for example?

Sorry to bother you, I just want to be sure before purchasing it! I'm also thinking, as an alternative solution, to use the viewfinder when shooting. Does it work while recording?

Hi! I'm thinking about buying a 5d3 to use it with Magic Lantern but before doing it, there are few things I need to evaluate:

Do the 3.3k, 3.5k and UHD 1:1 modes offer continuous shooting?

What's the crop factor of the 3.3k, 3.5k and UHD modes?

Does the 5.7k mode offers continuous shooting?

What's the liveview status of the 1:1 and the 5.7k modes? Is it frtp? Is it cropped? How fast is it?

Thanks!

But I'm interested in the Eos M, that's why I was asking here. Anyway, I'll wait for the next Bilal move, thanks.
