Done that, set Bit depth to 10 bit, and the mode works. Thank you!

Cannot get the camera working at 1920 50p mode for more than 15-20 sec. The settings are: autofocus off, stab off, 720 50p in Canon menu is on, Kill GlobalDraw is on, Card Spanning is on, SD is overclocked. I've tried ALL-I and IBP modes.

Anyway, it gives the following:

There are compression errors.

What am I to do?

Thank you so much, never knew of that.

UPD: the Full-res LiveView mode finally works. But the workflow on my 2008 Mac Pro is a piece of... something.

Using Dec 11 2020 mod. Cannot run Full-res LiveView mode. Card Spanning is on, preferred card is CF. Using best recommended cards. What am I to do?

Otherwise, great mode.

Thank you.

Cannot find a link to an interactive page that shows graphically the frame size and the needed write speed.

So what am I to search there for?

Is it possible to implement h.264 4:2:2 10 bit recording for this camera?

It seemed to me that there are some focus pixels in the frame. I've also tried to fix bad pixels, but it didn't work. What am I to do?

Could you, please, be so kind to tell me if there are any focus pixel maps for 5D3 1.1.3 1080 full sensor? Cannot delete focus pixels in MLVApp.

Could you, please, be so kind to tell me if there are any focus pixel maps for 5D3 1.2.3 1080 full sensor?

Please help me choose
I decided to buy 5Diii or 6D

Can I have a try giving an advice? In my opinion, the best buy is 5D3, because it is the best camera for ML and especially for shooting an uncompressed video (losslessly compressed, more like zip, rar or whatever). You can use the fastest SD and CF cards, overclock the SD controller with sd_uhs module and use the card spanning mode, when 5D3 writes on both cards simultaneously. Thus you'd be able to shoot in the highest definition possible. Non-anamorphic 1-1 mode is 3K and anamorphic full frame mode is 5.7K if I'm not mistake, all 25fps, thanks to Danne. You can also shoot in 1080p full frame binned mode. You cannot shoot 5.7K or even 3K with 6D continuously. I can do that with 5D3 with SD Sandisk Extreme Pro 64 GB 170 MB/s and CF Sandisk Extreme Pro 128 GB 160 MB/s installed.

So, I'd like to advice you to buy 5D3.

The key point is that you have to choose the 5D3 with the Canon firmware version 1.2.4 or less, to be successfully downgraded to 1.1.3 or 1.2.3. I was a lucky because I've bought the cam with 1.0.4 firmware, so I had to upgrade it.

Yes, I know, I'm sorry. Thank you for your great work. I think I'll update to Jul15 build.

Today I had a heated discussion with one person who tried to prove to me that modern Sony 4K domestic cameras, like FDR-AX43, gives a much better picture than 5D Mark III. None of my arguments about ML were successful. He said that 43 has much better sensor.

It says that 8-11 and 12 bit lossless are not supported with high resolutions. So, 10 bit is plain and 14 bit lossless.

Plain 14 bit or lossless 14 bit?

I'm using Sandisk Extreme Pro 64 GB 170 MB/s SD card, not fake one.

Yes, the card spanning is enabled.

I'll do the test soon. So, 10 bit 1920x2340 24fps, sd_uhs patch on, Global Draw set to "LiveView", card spanning set to on?

Still getting compression errors with fps=23.976, Global Draw = "On, all modes", card spanning and sd_uhs are on, bit depth 14 lossless. Maybe I should switch GD off and set bit depth to 10 bit.

What's most interesting, I'm getting errors under certain conditions, depending on what I'm shooting. Is that so because of 14 bit lossless?

How to make screens without taking pictures by iPhone etc?

Last but not least: I'll be using Helios 44-M4 F2 58mm soon, as I'll get chipped M42-Canon adapter.

Bit depth is 14 bit lossless, fps is 23.976 (tried 24.995, got even more compression errors), card spanning and sd_uhs are on. Global Draw was set to "Liveview". Set it to "On, all modes" - and no compression errors at 23.976 fps, but there are compression errors "-3" at 25 fps. This mode wasn't supposed to work with 25 fps?

No, the CF card is not fake.

Thank you, of course, but it shows multiple compression errors. Here is the log.

I'm deeply sorry, what build is this? And how to get that 5.7K mode?

Now I'm using crop_rec_4k_mlv_snd_isogain_1x3_presets_2020Jul14.5D3113 build.

I've got Sandisk Extreme Pro 120 GB 160 MB/s CF. Can shoot anamorphic 5K 25 fps continuously using card spanning. Fantastic. Never thought before that it can be possible. Just think: 5K @ 25 fps CONTINUOUSLY.

Benchmark shows 91 write for CF and 65 write for SD (Sandisk Extreme Pro 64 GB 170 MB/s). So total throughput would be approx. 156 MB/s? Is there any higher resolution mode? Can full frame 5.5K mode work at 24 fps?

The missing image from the previous message:



1.5 Gb/s!

Thank you, Danne, MLV App really does it, so no problem at all. Great program.

By the way, is it possible to get 5.5K anamorphic working at 25 fps?

Is there any utility for automatic merging of the files after using the card spanning?

Thank you so much! It works. 5.5K anamorphic mode gives the best picture I've ever seen.

I've decided to use Sandisk Extreme Pro 64 GB 170 SD card previously used in 100D. Cannot use 100D after 5D3.

Got the thing about *.m00 files. I have to merge *.mlv and the corresponding *.m00 file manually.

Can anyone please be so kind to tell me how to use card spanning on 5D Mark III?
