Set preferred card to sd card. It will send H.264 to SD while RAW goes to CF card...

Thank you! It works. I have never used this setting before, but recorded on both cards. Very strange.

Changing preferred card in ML menu is not required - all you need is to change the current card in Canon menu. H.264, being a Canon feature, uses that setting. The "preferred card" option only operates at startup to change the selection from Canon menu. It does nothing else - read the help.

On this branch, RAW/MLV always goes to CF if there's one inserted (for speed reasons).

Changing preferred card in ML menu changes preferred card in Canon menu (after reboot). So in order to record on two cards preferred card in Canon menu must be SD.

Thanks :)

First post recommends something else (real-time uses too much CPU), though I might have something that will help (check twitter).

I'm curious too... Checking Twitter every day but nothing yet.

Have you checked on April 1st? It was there when I've written that. It's still there. What do you expect?

OK, maybe it wasn't interesting enough, judging from other forum posts. Anyway, my CF card is dead from that experiment, so I'm taking a short break.

The source code is online, you can push it forward while I'm taking care of other parts of ML (not video-related).

Aaahhh, ok!! SD card overclocking...
I didn't expect nothing. Just I didn't know what were you talking about.
Thanks for the clarification.

I'm a big proponent of Magic Lantern. I lead the Creative Cow Canon DSLR forum and constantly recommend it as well as work flows.

My question I have for this forum and maybe it's obvious and I'm missing it, but if I install the latest experimental build of the 4k version of ML on my Canon 5D Mark III with 1.3.2 firmware, do I get the same nightly build as "magiclantern-Nightly.2018May01.5D3123" which I currently have installed, WITH the ability to do 3K/4K cropped? or are the normal feature in "magiclantern-Nightly.2018May01.5D3123" missing and it is only focused on3K/4K cropped?

In other words do I get everything the normal nightly build has plus the addition of 3K/4K cropped?

TIA!

Hi a1ex + ML geniuses, thank you for all your amazing work!

Wondering if you can shed some light on a buggaboo I'm having. All of my normal 1080p/24 RAW footage is great. I load the Raw video v2 (mlv_rec) for that and shoot 14bit lossless and it looks fantastic!

However, when I replicate your settings exactly for shooting 1920x818 48p for slow-mo, the footage just comes out with a black preview (or one broken image preview for all dngs) and unrecognizable as a dng for use after conversion (MLV Mystic, MLVFS, raw2dng, Mlrawviewer). Here are my settings:

-magiclantern-crop_rec_4k.2018Mar10.5D3113 (I've also tried 2018May1 build)
-5d Mark III firmware 1.1.3 (I've also tried v1.2.3 - no luck!)
-Modules: crop_rec, mlv_lite
-RAW Video: On, 1920x818, 2.35:1, 14 bit lossless ~50%, preview: Real-time, no Sound recording
  (says in green - 62.9MB/s, 120x2.2MB, 48.000p (50%). Continuous recording OK.)
-Crop Mode: 1080p45/1040p48 3x3
-Canon Menu: 1280x720 60fps ALL-I
-FPS override : OFF (automatically shows gray 48.000, Rs.83% which should be great)
-ISO: 100
-Shutter 1/130
-Global Draw: I've tried both On and Off, same result
-CF card for record: SanDisk Extreme Pro 128gb 160mb/s, SD card for firmware: SanDisk Extreme Pro 32gb, 95mb/s

I've tried every Data Format configuration. The only one that works has been 10 bit uncompressed.

Were you able to get 14bit Lossless to work, and if so, could you tell me what I'm missing? I've reloaded all the firmware exactly how it's supposed to be done, tried v.123 as well as v.113 (what I'm using now) and nothing seems to work, the footage is not in a supported format when converted to dng (I've narrowed it down to where it seems the original mlv's are corrupt in some way). When I switch to mlv_rec (v2) I am able to record usable footage so it doesn't seem to be the camera or the cards, but I don't get the same size options as using mlv_lite.

I'd love to be able to shoot RAW slo-mo at 1920x818 2.35:1 48fps if possible. I'd be grateful for any help!!

Thanks!   :)

Maybe it's your method of conversion ?  Your MLV conversion must be able to decode the lossless format.  I'm using MLVFS but there's an updated version that can convert lossless files.  You could try uploading a short clip to see if anyone else can decode it.

14bit lossless is only in mlv_lite.mo not mlv_rec.mo

Have you tried MLV App ? same thing?
If it still not working I assume the MLV files is corrupted. Because as a1ex said:

Regarding 1080p48 - it was pushed a bit over the safe limit, so I've reduced its resolution to 1040. You still have the option to go back to 1080 in the crop_rec submenu; however, you'll get a lot of errors. With some fiddling, you can probably get 1060 (e.g. set Target YRES to 1060 and Delta HEAD3 to -20), but I wouldn't trust it yet.

So maybe you can override it to 45fps or lower the resolution in 48fps ?

EDIT: I saw you have already lowered the resolution to 1920x818, so maybe it's about converting method, Try MLV App.

Switching to the MLV App did the trick. The footage converted just fine! I ran a load of tests today and I'm able to do pull 1920x1040 16:9 in 14bit lossless at 45fps just fine. I tried to do it at 48fps but only got 9 secs. However when I turned Global Draw off, I was able maintain continuous recording. (Also the 1920x818 works great at 48fps.)

Again, many thanks for your help. Sometimes it's the simple things.

One question - when forcing 45fps for 1920x1040, I can't select 1/130th shutter speed but can do 1/80 or 1/180. Which would you guys recommend?

That should be done from Canon menu, as FPS Override is not fully compatible with crop_rec at the time of writing. Refer to previous posts for details.

FYI, lowering the resolution in the raw recording menu has absolutely nothing to do with what I said back then. The video mode configuration (including the likelihood of getting corrupted frames) is given by crop_rec settings, so if you have problems with randomly corrupted frames, you should reduce the vertical resolution in the crop_rec submenu, not elsewhere. Reducing the resolution in the raw recording menu simply selects the crop area that ends up recorded, but does not affect the image capture process in any way.

This does not apply to pgrandaw's issue; it's just something to keep in mind when recommending things for troubleshooting.

Thanks a1ex, yep I have the Canon menu set to 1280x720/60. I just didn't know if I should manually set the FPS override to 45p but it seems to be capturing 48p with a 2.35:1 ratio so that's awesome. I won't set any override.

I know you've heard it a million times but thank you!

I am experiencing different shutter speed recording in resolutions higher than 1920x1080, mainly in the 3.5k 1:1 mode. I set my shutter at 1/50 for my regular 1080p 14 bit recording but when I change to lets say 2880 resolution, the maigclantern shutter speed suddenly shows 1/30 or so, but also after having imported the footage it says 1/30 while my Canon shutter speed is on 1/50.

Also the whitebalance doesn't work in crop mode 3.5k 1:1. everytime I 'half-press shutter' in 3.5k mode, the liveview has a completely different tone than when not in crop mode

Is there any discussion or development on a >1080p H264 mode?

With the 40MB/s cameras the limitation is SD write speed, so maybe we can pipe the enhanced resolution of crop mode into a compressed file?

I know we will have other bottlenecks in the system (like reading from the sensor, the digic processor compression, etc etc) and probably can't even do 3K, but even 2.5K H264 mode would be spectacular!

(Many thanks for what the devs have already achieved - in asking this I feel like a kid asking for more presents after already opening a bunch of awesome ones already!)

H.264 encoding for 1080p is done in hardware (blow up from native LV resolution to Full HD, noise reduction, sharpening) and IMO there is not that much knowledge about chip's abilities.
Don't hold your breath.

Is there a quick printable/savable user guide for this experiment version. I keep forgetting the steps to set this up on camera.. Any help appreciated. Thanks!

Video on page 1, post 1 doesn't help?
And storing those settings (config preset) would be helpful, too.

OK relooked at video again. Yes I can do that way. Then save as presents.. Thanks! Been a while since I did the 4K and want for a trip I am about to take. CHEERS!
