Newbie Canon 6D ML installed but stops after a few seconds help please

[dreamplayhouse]

Hi there,
Installed the build found on this page for my 6D running firmware 1.1.6 https://builds.magiclantern.fm/6D-116.html
Can someone let me know what settings to click off so I can record continuous RAW video? Or at least for 1min if possible.
thank you

This build is limited to 720p for continuous recording and only if card is fast enough.
Test card speed in cam: Switch to photo mode. Access Modules tab and activate bench.mo. Restart. Access Debug tab -> Benchmarks -> Card benchmarks -> Quick R/W benchmark (1 min).
Numbers should be above 40 MByte/s.

If you want higher resolutions you need other builds like experimental 4k crop_rec build or Levas's build for 6D: https://www.magiclantern.fm/forum/index.php?topic=25782.0
Both builds require a fair amount of testing and fine-tuning. Don't expect them to work out-of-the-box.

Thank you.
Write was around 23 and Read was over 44. What kind of card do I need? This one is 64GB Sandisk Extreme PRO 95/MB's.

[Walter Schulz]

Are you shure you tested in photo mode? Doesn't look like this card. Could be a faked one. Write speed should be above 40 MByte/s.
You may verify/falsify card type by using a decent cardreader and tools like CrystalDiskMark (Windows) or Blackmagic Disk Speed Test (macOS).

My numbers for my SanDisk Extreme Pro 95 MB/s with CrystalDiskMark (64 bit) on Windows 10 with Kingston FCR-HS4: 98 MByte/s read, 88.40 MByte/s write for SEQ1 test.

Had the small switch on the 6D set to photo

Under ML-Movie Aspect Ratio, only 5:1, 4:1 and 3:1 show in green on the bottom of the LCD, the rest in yellow.
I was able to shoot in 3:1 but that's very thin size.

So I do have another Extreme Pro card. Do I just load ML onto the card and start my 6D without any firmware updating again?

Thanks! got it working with another card.

Are there good EF mount lenses for video with image stabilization at around 28mm F2.8 ?

Benchmark numbers ok this time?

[Levas]

I see you're using the nightly build, you might want to check out the croprec4kbuild for 6d, it's on the dowloadpage -> experiments.
https://builds.magiclantern.fm/jenkins/job/crop_rec_4k/80/artifact/platform/6D.116/magiclantern-crop_rec_4k.2018Jul22.6D116.zip
(Spoiler, there is no 4k on the 6d, there is only 4k on the 5d3  )
But This build has the lossless raw recording option and even lower bit depth lossless raw recording. I think lossless options are missing in the build you're using ?
Lossless improves recprding times a lot.
The experimental build has a module mlv_lite (you don't need mlv_rec module)
This mlv_lite module has lossless raw recording in 14 and 12 bit depth, or even lower.
Lossless recording in 12 bit is on most normal sd cards continuous on 6d.

haven't tried since it's working now

Great thank you!!

When I try this experimental version set to 720p and 12 bit lossless, the LCD screen is super laggy

[Walter Schulz]

Try grey scale display (B&W).
As I said: It will not work out of the box and fine-tuning is needed.

[Levas]

There is a preview option in the submenu of raw video.
It's probably set to preview or auto, if you set it to liveview, you should see normal liveview as you're used to.

And with 720p, do you mean you have your camera set to 720p 50/60 fps in Canon menu ?
If so, you will get a raw recording that has to be vertical stretched by about 1.67 factor. (Canon is skipping some vertical lines to get to 50/60fps)

If you don't mind having 25/30fps, you're better of with normal 1080p mode in Canon menu. In this setting you don't need to stretch the footage by a factor of 1.67

Thank you that worked!

So now I have video set to ON, 1824x776, 2:35:1 and 12-bit lossless.

Are these the best settings I can get with the 6D for RAW continuous?
thank you

[Levas]

Yes, for continuous recording I guess these setting should work very well with most cards. And it's the most stable and convenient way.

1824x776@25fps is about 37MB/s in data. (Standard max write speed of the 6d tops around 40MB/s)
Lossless compression varies depending on the scene, bright scenes get less compression. So if you really get continuous recording times also depens om the brightness of the scene.

For magic lantern beginners the above build is the most convenient to get used to working with raw recording.

There is a build with a module that gives the 6d more write speed, but you do need a sd card that works with it. With a compatible card and that build you can shoot continuous in 16:9 aspect ratio ( 1824x1026)
But it's all a little bit more fidely.
My advice, first get used to magic lantern and raw recording.
And once you feel the need for more you can read this topic, which contains more experimental builds for 6d.
You might experience some lockups with these more experimental builds, in that case, take out the battery and re insert and start camera again
