sorry , big confusion here...2 questions please.

1) for decode dng files of this exp.release , must be used only with last release of mlv_dump (line command without interface) ? because I try anothers programs, but are not compatible, only pink and black dng.

2) any one can please tell me, the right setting for recording in 1920 50p  ?  must be select also in menu canon 1280x50p  or can be  1920 x 25 all-i) ?   must be set  FPS over to 50 ?

As long as you use the Experimental Build, you have to use mlv_dump. Its located in the same page to download.
From the Camera-Icon menu / Crop / 1920 50/60 3x3
You have three options.

If you select Canon's 1920x1080 25FPS, you get 1920x1080 25FPS.
If you select Canon's 1280x720, you get 1920x960 50FPS.
If you select Canon's Video System as NTSC instead of PAL, you get 1920x800 60FPS.

thanks, now is ok.
for a recording 1920x960 50p  continued , can be set 14bit loss ore better 12 ?

I've tested 1920x960 50p 14 bits lossless, convert the .mlv file with mlv_dump, all .dng are black for the moment, don't know why. I had no error message during the recording and stopped it myself.
I've also tried 4K at 24p, but I haven't found the way to get the 4096 x 1440 ratio it is written everywhere?
In 4K, preview isn't working, right?

Thanks and many thanks to all the team which is doing so much work to fill the gap Canon has let behind.
I'm currently finishing my second short with the help of Magic Lantern and it is great to be able to get such video quality!

Are they black if you look at them in After Effects or Resolve?

Which converter did you use @motionSOUL? Latest cr2hdr.app has been working quite flawlessly w lossless MLV's as of late.

No, I've used mlv_dump from the Terminal. I will test cr2hdr.app, which has just converted a 4096x1366 test file to .dng flawlessly.

What is better 12bit or 14bit lossless depends on an image content. It is a pity that 12bit (10-8) lossless is not available for this mode.  For 1920x960 @ 50p (both 1:1 crop and full-frame - 3x3 pixel binning) recording length depends on an image content. Sometimes 40 sec, sometimes 10. But for 40 fps (FPS override, Exact fps) I got continues rec. SanDisk, Extrime pro 160MB/s, 256GB.
BTW could not set 4096x1440 @ 25p (1:1 crop) mode. How?

Hello A1lex,

Do we have to do something when the Memory patches is turned red, red on Code:FF28CC3C?
It seems to have appear after my first test with the Apr23.5D3113 build when testing 1920x960 50p, I had the screen filled with error alerts, then this...

Thanks,

S/.

Can someone write tutorial about how to rec on these modes? Why do I get this http://joxi.ru/YmEqBpZF06jjnm.jpg instead of DNG? What mlv_dump for?

Also I don't get how card spanning is working (it seems it doesn't) for when I enable this mode then at 3200x1200 it record 4 seconds (I checked it with various superfast CF-cards), but with only one CF card it also rec 4 seconds only!

mlv_dump is lovely!!  make sure you use the mlv_dump in experiment page. otherwise you end up with noisy pink DNGs. been there before.  or you can try the amazing cr2hdr.app. (note: dont judge the frames by their thumbnails. open them in photoshop to see if they are converted right. and not the first frame also!)
I see you have opened the first frame which is usually pink and corrupted with this mode. have you tried other frames too?!

this is MLV_Lite with this build which is different than the old MLV. MLVRawviewer and raw2cdng can't open it or they deliver pink DNGs instead.

Read the little help text at the bottom of your screen.


yes , but also is write green 80 mb/s CONTINUE rec. 

after 10-12 seconds a sequence of BEEP and stop the recording...

so I try anothers crope mode...like 3k , I crope like I have 70/80 mb max writing and compare continue recording...

preview is slow and gray  , recording number  stay green....(think normal) but after 10-15 seconds ...STOP !

CF is perfect (x1066) and work very well without stop with normal raw to 90/100 mbs

I don't know why many anothers here say can recorded continued in same situations....

What brand CF cards are you using @jimiz? Are they formatted into exFAT at the very least?

Also were you using '3.5k 1:1 center x5' within crop_rec.mo from ML menu and more importantly did you enabled FPS override to 23.976 while in x5 zoom?

Here's a screenshot from MLVFS webGUI to show that I was able to achieve continuous w 12-bit lossless in both 3072x1308 & 3072x1320 in 24p @ ISO 3200 until pressed stop.



This was used w KomputerBay 128GB 1066x and it was formatted to exFAT via Disk Utility on OS X prior to recording (256GB cards can be formatted in cam while keeping the exFAT).

Settings used under Movie mode within ML:

5D3.113 • 5D3.123 • EOSM.203 • 7D.203 • 70D.112 • 100D.101 • EOSM2.*

@DeafEyeJedi has the magic settings here. I can verify most of this. But you need to make sure ML is on your SD card and you are recording to  your CF card that is formatted exfat from your computer. DeafEyeJedi settings are exactly what I have been using. It you want a smidge extra headroom you can set it to 2.35:1 which brings your vertical resolution down a tiny bit ... I think.

Edit: actually... I just got these settings to spike!
ISO 100 at some very bright trees! It went from like 89 MBs to 114 MBs I'll upload a dng

At the 11-8 bit Lossless with 3008x1280 I was able to get the same scene down to 90ish A1ex was right! (Not hard to believe) that you can get seemingly continuous settings to spike high! Very high

But where is this experiment page? I just download build pack and mlv_dump.exe but what should I do with this exe file? I actually can't understand why it so difficult to write tutorial about how to use these.

@Savely
What modes exactly? This tutorial would be a lot to go through. I assume you read DeafEyeJedi settings and you are up to speed on the new build.
I have some that would offer even more stability depending on what you are filming.
3008x1280 11-8 bit lossless MLV Lite with preview set to auto.
Crop rec mode set to 5x zoom 3.5 k mode
Also it looks like you are having post processing issues.
If so it's easy.
For windows:
1) Download RawFlow v0.2 http://www.magiclantern.fm/forum/index.php?topic=13338.0
2) Download new MLV_dump https://builds.magiclantern.fm/experiments.html
3) Open up the Rawflow folder and delete current the MLV_Dump that came with Rawflow and replace it with the new MLV_dump you downloaded from here  https://builds.magiclantern.fm/experiments.html leave this folder open for now.
4.) download your MLVs off your card to a new folder on your computer.
5.) Open up the RAWFlow folder if you closed it.
6.) Select all your MLVs and drag and drop them right on the Rawflow.exe application icon in the Rawflow folder (note you do not have to open the exe or run it. It will do that on its own after you drag and drop mlvs on it)
7.) The app will open a command prompt window. Let it do its thing and it will place new folders in the same folder as you MLVs with DNGs for you to play with.

Hope this helps and hope this doesn't break your camera or computer. I think this workflow is similar on MAC but not sure.

@DeafEyeJedi
sorry to double post but it appears that even 3072 x 1308 12bit lossless 23.976 fps ISO 100 under 5x zoom can cause a spike in data rate. Like I think it said 117 MB/s
@A1ex told me that if you try hard enough you can find a scene that can do this. It appears that it's not just high iso that can cause a data rate spike. Even at iso 100  12bit with a brightly exposed detailed scene that data rate can shoot through the roof. I assume if the details are bright enough to stay out of compression then this can happen. That's my guess anyway. I was able to get the scene back to 90MBs by using 11-8 bit at 3008x1280 here is the DNG that went off the charts.
https://www.dropbox.com/sh/8lmopv8z7p2i91f/AAA4saYTmLE7rFQ3t7nSUBCaa?dl=0

1920x1080 14bit lossless 24p was still okay. Not even close to danger zone.

EDIT!!!!!!! I actually tried to rec this scene at 1920x1080 14bit lossless 24p even tho MB/s was good but it gave me an ML assert
ML ASSERT:
0
at mlv_lite.c:2344 (compress_task), task compress_task
lv:1 mode:3

Then I notice that the compression ration was at 106% or something like that. @a1ex I found the scene you were talking about!
all frames are here:

It will be nice to have an option for manual bit lossless setting in order to reduce data rate.

Not after seeing samples like these, but feel free to prove me wrong.

The automatic choice is on the gradient 3-bit tonality border (any lower bit depth would result in obvious posterization).
