Circular Polarizer.
Because there is no mirror in EOS M design a linear polarizer will do, too.
But I think what he is trying to say is named "Variable ND".

Thanks for the correction to my typo @Walter Schulz!

You got some test footage I can see of the 14fps? Doesn’t it look choppy at that speed?

I consider 14fps anamorphic as a photo burst mode or timelapse mode more than a movie mode preset.

It's a very right path though. Many movies use 12 or even 6 fps shots for certain dreamy sequences or plates. I already have one in mind, that needs a low fps plate.

Just out of curiosity, where's the bottleneck in allowing full sensor readout to be recorded with 24fps? I mean, could we achieve a few frames at all (250?) And, can anything be done with the dark liveview while recording 1080p with a bitrate lower than 14bit?

Timer registries are connected with readout. I don´t know the full story but increasing fps reduces with(black border) or we get corrupted frames and so on.

Don´t know about darkened output? Could you share examples? A bit darker but that comes with the territory reducing analog gain registers. Liveview brightness reg is pushed quite a bit to compensate for 10bit so it shouldn´t be a big issue.

Hello to all, I've a problem that after I download the latest version(seb.19) of ML, and I found that I can neither change my ISO nor shutter speed. this's my first time using the ML. Maybe my seeting was wrong. plz help me! :o

Agreed. Try using both Dual-ISO & Circular Polarizer together for decent results. Indeed, it's such a killer combo!  :P

@danne Ml fails to load after turning on camera without the card then inserting back the card with ml (haven't tested putting card without ml)
1. Remove card with ml
2. turn on camera without card
3. insert card back
4. turn on then no lcd, led blinking yellow green
5. tried the battery pull and switching with and without card first two times worked after more or less 5 tries. Third time worked after like 15 times of it (different random combinations of pull from battery pull and on without card, battery pull on then insert card, on with batt and card then pull battery). After booting it displayed the "skipping loading modules"

I don't know if this matters, maybe someone may accidentally turn the camera on without the card or something. Thanks!

I tried to reproduce but removing card and starting camera simply starts it saying there´s no card present. So then I turn off the camera and put the card back in and restart and everything is back to normal again. Couldn´t reproduce the hang up. Then again I didn´t test very hard. I think one shouldn´t. It´s better to uninstall ml if not using it or removing the card etc.

Thanks for the example. I think it can be quite useful in some situations.

It would be nice to have an optimal preset for 18 fps silent (audio) film.

- 18 fps 1736x2180 (2.39:1) anamorphic mode

If ratios are set to OFF and you then enable set_25fps in anamorphic rewired mode fps will have a boost to 18fps and set resolution to 1736x2180. Don´t forget to push MENU once to refresh regs.

This mode is continuous in 10bit. It´s actually possible to push to 20fps but not continuous.
The 14fps mode can be pushed to 16fps but will only record shortly. If you want to push these limits go into the registry section and decrease reg_6014 and/or reg_6008.

When you turn on the camera without card, it loads the original firmware. This procedure (starting without card) is the first thing one should do if the camera doesn't boot (see the Troubleshooting section on the main download page), so warning others not to do this, doesn't make any sense to me.

Quote
"skipping loading modules"

This one appears after a bad shutdown while you were running ML. That is, after removing the ML card, the camera was not fully turned off, and when you started it without card, it was actually running from the previous (ML) session. I've seen Canon firmware canceling a shutdown in the past (if you power the camera back on before the shutdown completes, or if something goes wrong with DryOS). So, yeah, I can see a way for this to happen after a crash.

If the camera doesn't boot, remove the battery and retry. The power button doesn't actually cut the power; it's just a soft button, so it's not going to bypass a software lockup. Same for the battery/card door.

I think one shouldn´t. It´s better to uninstall ml if not using it or removing the card etc.

Sorry, but that's nonsense. Using a formatted card, or removing the card, are preferred ways to start the camera without ML (see FAQ and install guide). One shouldn't have to run the installation procedure back and forth.

Bootflag reset is always good if not using ml.
Also formatting a sd card with ml ongoing often seems to be a cause of issues restarting etc. Walter mostly comes to the rescue here ;). Seems uninstalling properly will take care of most issues that's all.

Bootflag has no effect on the issues discussed above. Other than a small delay at startup, when the bootloader is checking the contents of the SD card (see this flowchart), there's absolutely no effect on camera functionality.

Also formatting a sd card with ml ongoing often seems to be a cause of issues restarting etc.

Links, please...

Don't remember any such issues after reformatting. After format the card is clean and there may be a problem with diagnostics like portable display autoexec.bin and lost ROM.BINs (if needed).

Ok,ok. I only vaguely base my assumptions. Could be erasing not formatting causing issues.
I would like to rewrite my former message.
Please don't seek ways to break start up routines removing card or other ways in my ongoing builds. I don't have the time or enough knowledge to provide more than bleeding edge experimental builds. And in this case many presets includes heavy use of movie crop mode property regs. Other automations might also become problematic if for some reason interrupted.

That’s great, thanks! I normally record in 16:9 but will try this out.

I want the full width so the compromise to get 18fps is 2.39:1.
I guess full width could be kept an 24fps if we want to use a more narrow ratio than 2.39:1. Could be interesting.

So we have:

1464x1836 at 24p (64,509,696 pixel / sec)
1736x2180 at 18p (68,120,640 pixel / sec)
1736x2996 at 14p (72,814,784 pixel / sec)

So maybe 24p's width could be pushed till about 2072(?), with height and fps unchanged. And / Or full width and lowered height of course, may be a variable for setting its ratio between limits?

Changing cmos 7 to 280 allows for higher fps but only tested some. Even if we could reach 24fps here it's not continuous without highly reduced height so maybe just stop at 18fps until we see some actual use here  :P

@Danne -- I just wanted to let you know that while I appreciate your hard work on fine-tuning this mighty beast nevertheless recently I couldn't stop puzzling myself at why occasionally if I were to 'abuse' the half-shutter to check focus in x10 zoom and back to normal viewing thus forcing me to either turn off cam and back on (not very often requiring a battery pull) just a simply shut-down and back on seems to do the trick.  :-X

Atm I'd give this Sticky Push about a 75-85% reliability rate (if not better) which is far more than what we can ask from you. Regardless I'll continue to abuse this bad boy to try and find a way to reproduce this so called phenomenon since this is indeed an useful feature.

Rather than the usual double press Menu button which would normally refresh the registers but apparently I'm pushing this a bit over the edge, right?  ;D

Also I just realized you can't really combine Magic Zoom with the Half-Shutter Sticky Push together (unless you turn off Global Draw completely while in recording mode) which to me is a dealbreaker. While I enjoy the newly sticky half-shutter feature... we know we shouldn't fix what's not broken re: Magic Zoom. All about compromise!

Are you using sticky push? If not do that and see to it that halfshutter is pushed until reaching x10 zoom.

In the Sept20th build I have a bug at Playback
this happens seeningly if the ratio is set to off This doesn't happen with 2.5k 1:1 or Ana modes
2. maybe the 3x also an issue there

So if I set ratio to OFF and record mv1080p rew. and go in Playback, the LED is on and the screen black. The cam doesn't freez or something, I can reach the Record mode just  with a tap on the screen .

Just a report. Please check anyone.
Many thanks to Danne and pthers
