Canon EOS M

[2blackbar]

Theres annoying issue with "Card is Full" screen when well... card is full, you cant even enter ML menu to remove some mlv files, camera locks you out.
Is there any way to make camera restart raw video once it was stopped by camera ?
Sometimes i hit record and go away from camera , or is there "BEEP" sound so i know that video was stopped when i hear the sound ?
--
Ok i found restart and works great, but i cant find the beep, sync beep doesnt work or i dont hear it anyway.

[Danne]

You have Movie Restart under raw video menu settings(thanks to Jip-hop enabling this for raw files)
If you want to have control over actually stopping camera from recording before card gets full for instance you can enable the movie tlapse & rec delay script.
Under Movie tab go to recording delay. Set rec delay for when to start recording. Set recording time for when to stop recording. I think it will even work with Movie Restart enabled as well. Should get you in full control.

Edit: Beeps don´t function on eosm. At least nothing I managed to hear.

https://builds.magiclantern.fm/features.html  -> Audio -> Beep
M not supported.

[2blackbar]

That clears up everything, thanks guys !

[Walter Schulz]

Maybe asking Dmilligan if there is a way to beep via properties might be a good idea. IANAP

[2blackbar]

Yeah ability to play any sound notification when recording stops would be nice but rec auto restart fills that gap nicely.

Hello Danne,
big thanks for your work. Just tried your build for the first time.

I am unable to lower the gain with the down button. It pops up canon ISO choosing menu, but I am unable to select lower ISO there. If I select ISO value there on the touch screen,the ML preset choosing menu appears. If I select it with wheel+set - nothing happens with ISO, in just returns to ML liveview.
Rising ISO with up button works well, goes up to 3200 . Maybe I have to make some configuration to make it work. Please advise.

Update. I've found the cause. In canon menu the function of delete (down) button was set to ISO choose. I've reset it to default, gain lowering works fine now.

[2blackbar]

Danne is there a way to force camera to be in 24hz ? Now its 32 from what isee in fps override

[Danne]

Why would you do that? But search in crop rec or fps engio code. It's in there.

[2blackbar]

To see if it will affect image, motion blur, anything at all.I do notice a difference in motion blur when you switch on/off fps override

[ngemu]

I noticed the right button on the scroll wheel isn't available to assign as a custom button. Maybe we can use that for other features like switching between framing and liveview so we can free up the info button? Or maybe a button to cycle between isos from 100-400?

Great work as always Danne

Centered c mount lens for 2.5K mode , now it works fine centered in full 2520x1054  and in 1920x1080 modes.
Its useful when you vignette on 4mm with 4-12mm zoom at full 2520x1054 and when you zoom in to 8 you dont vignette at all , previously you had to zoom in to 10 to get rid of vignette in one corner, now youre getting rid of all 4 corners at once cause its centered.
1920x1080 mode does not vignette on 4mm but it does on 2520x1054 so when you zoom in then COC gets bigger and you can fill entire frame from 8mm , works perfect.

Code: [Select]

               
            case CROP_PRESET_2K_EOSM:
  cmos_new[5] = 0x2c0;             /* vertical (first|last) */
              cmos_new[7] = 0x2a9;    /* pink highlights without this */
                break;
Centered left and right:

Code: [Select]

        case CROP_PRESET_2K_EOSM:
            /* set ratio preset */
            if (ratios == 0x1)
            {
                skip_left       = 36;
                skip_right      = 36;
                skip_top        = 28;
                skip_bottom     = 18;
            }
            if (ratios == 0x2)
            {
                skip_left       = 36;
                skip_right      = 36;
                skip_top        = 28;
                skip_bottom     = 0;
            }

            }

[bakersdozen]

Are you using something like this?

[2blackbar]

Im using f1.4 tamron 4-12mm and i ripped plastic cover to expose aperture mechanism and control it.Im planning to get something from 12 to 80mm maybe more tele as well.
Crop mode on M is exact fit for 1/2" lenses, 2/3" and super 16mm film camera lenses
--
Adjusted 2.5k again, i had thin lines probably because skipping top and bottom was not accurate.

Code: [Select]

case CROP_PRESET_2K_EOSM:
            /* set ratio preset */
            if (ratios == 0x1)
            {
                skip_left       = 36;
                skip_right      = 36;
                skip_top        = 8;
                skip_bottom     = 38;
            }
            if (ratios == 0x2)
            {
                skip_left       = 36;
                skip_right      = 36;
                skip_top        = 0;
                skip_bottom     = 28;
            }
            if (ratios == 0x3)
            {
                skip_left       = 197;
                skip_right      = 197;
                skip_top        = 8;
                skip_bottom     = 204;
            }
            break;

Code: [Select]

            case CROP_PRESET_2K_EOSM:
  cmos_new[5] = 0x2c0;             /* vertical (first|last) */
              cmos_new[7] = 0x2a8;    /* pink highlights without this */
                break;
                Well , looks like lines are there from pressing left arrow on wheel and coming back to framing preview.They disappear slowly and are gone after about 10 seconds.

Hey all really need a bit of help.

I have an eos m. I noticed that there is a few dead pixels
i use mlvfs and i used all the options to get rid and there is still one little white dot left in near the middle

any help would be appreciated

[Danne]

There's a function in Mlv App which allows for adding additional dead pixels saved into a .bpm file. I don't have the time to explain further but take your issue to the Mlv App thread and you should be getting help.

- Mlv play stopped from going into black screen occasionally when previewing clips.
Needs some testing. The fix should apply to 100D as well but no time testing that one.
The fix starts while stopping mlv_play so first started clip might work or not but after that mlv_play should work fine.

[berechiah]

Thanks for the help
will look into it soon

- Mlv play
Testing changing aspect ratio while previewing anamorphic modes. Instead of a very anamorphic preview it will now show the correct ratio while previewing recorded files. Work in progress. Better metadata routines reading straight from rawc preferred.
Expect a bit of a lag and other expected behaviour.
Thanks to a1ex(or g3gg0) for the "fixme" line.

EDIT: Better detection in mlv_play. Uploaded new builds.

EDIT: Might have fixed the previewing issue when sometimes screen would get into black screen instead of serving a raw stream. Needs some testing. I also slimmed down on a few presets from the fast preset menu. Use SET for x3 cop modes instead.

[bakersdozen]

Correct ratio preview working well here. Well thought.

[Danne]

Yes, correct ratio working nicely now. Thanks for feedback.

Did some playing around with tmix averaging in Mlv App. Exported a 70 frame MLV into a singel tiff and worked some with the file in lightroom.

Comparison crop:

Before averaging:


After averaging:


Since doing averaging I expose measuring highlights, not ettr:


Colorful result and noise free shadows:


Recorded with frame burst set to 70 and the 5k anamorphic full sensor readout preset iso(200):
Also did some pixel picking in Mlv App since my eosm sensor inherits a cluster of dead pixels in the upper right corner.
I think I also added chroma smooth 3x3 but not needed really. But I liked it so used it.

Lens: Samyang 12mm at f4

@Danne

Can you also share your other settings, eg FPS, aperture and shutter speed etc

[Danne]

Updated. Settings at bottom of the post.

[garry23]

@Danne

Thanks.

BTW can you speak more to this

Since doing averaging I expose measuring highlights, not ettr:

Why not set exposure by ML’s ETTR?

[Danne]

Look at the result.
Shadows are cleaned/averaged. This way I get tons of highlights to work with.
