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

Maybe we are speaking across each other.

As a photographer, when I ETTR I am only interested in exposing for the highlights AND thus have shadow and mid SNR set to 0.

Hence, when I ETTR with these settings, I’m exposing for the highlights.

I mostly loook at the files and build from there. I'm a lousy "histogrammer"  :P.
I'm sure a little ettr on my my image would have helped even more. I plan on including the ettr module in eosm build when I get some time to use it...

Stunning work mate. I too am lazy in this regard, which is why I love your little tweaks for us [emoji1]

Thanks. Would be nice to hear about results and usage areas among users. Any missed links to other groups forums etc :)

Hi all, I'm loving these new builds, and have been playing around with the 5k modes. It got me thinking...

Part of the charm of these cameras is the filmic look, and with he preview in 5k being what it is, you need to be more intentional with each shot. It's far from point and shoot. Again, lending its self to the idea of shooting with film. With that in mind, a pistol grip and a loupe, it's a very nice experience.

So my question is: to complete the illusion, is it possible to shoot the 5k modes, but instead of cropping the top and bottom, can I crop the sides to get a 4x3 image?

16:9 is there at least. Why 4:3? You can try set ratios to off and set 4:3 in raw video menu. Maybe it works at somewhat lower resolution.

I'll give it a go. I thought 5k cropped the top and bottom to get more frames (longer shots). With 4x3 giving you more height, and less width, I could still get more frames than shooting 16x9, and not have to estimate my framing.

This is how ratios work (to my understanding). 5k max offers the biggest picture but unusable for the most part due to its cpu demand. By selecting the 2:35:1 ratio (on the outer menu), you get 4392x1870. It is more than just cutting the top and bottom of 5k max. It is quite a crop but offers decent shooting time from a couple seconds to minutes depending if you decide to lower the resolution a bit.

5k max and mcm rewire are similar in that they both allow you to record at the 'full picture' but the resoluton is significantly smaller and comes with drawbacks like more aliasing.

Please correct me if im worng, i do not know the right terminology.

Hi all.

I am using the Jan 14th 2020 build. Its great apart from a couple of small issues I am having with not being able to use 25fps and seeing focus pixels in h264 footage.

I am able to reset the config and turn off raw video and get the right 25fps and shutter settings (with fine tuning and locking), but I see focus pixels in my h264 footage.

If I use the h264 8bt preset by tapping the screen, then it seems to remove the focus pixels issue but the fps jumps to 29.973 and the set 25fps settings doesn't seem to have any effect.

Does anyone have any advice here? Any register tweaking I could try?

You can use h264 recording at any crop rec preset by like you describe, staying in a crop rec preset and disabling raw video. This means you will also get the focus pixels. That is the reason that you can select h264 from the preset menu. This turns off crop rec and raw video and records just as the camera normally do. You can also push SET and you´ll get x3zoom.
The fps jump to 29 is normal on eosm. Once you push record it will jump back to the fps set under canon menu.

Thanks for the help danne.

It does indeed jump to 25 when I hit record.

So is set 25fps part of the raw video or crop rec too? Is shutter fine tuning also limited/disabled in h264? I can only get 1/52 at the moment. No problem if thats the case, its close enough.

Cheers,
Dan

Also, one more question if you don't mind.

Is it possible to add the bit rate options into these builds? I'm planning on doing some raw recording, but still need to do the odd h264 things here and there.

thanks
Dan

You can define back bitrate function in code and compile yourself. I am not using it so will not add it back. Sorry.

I would just get an extra cheap SD Card 16GB/32GB for the h.264 stuff.
I don't get the pixel dots using the 8-bit preset. Like Danne said, I'd just turn off Raw Resolution.

Actually you need to choose h264 8bit from the preset list since only turning off raw video will stiil keep modified regs from crop rec ;)

Which is mostly fine apart from not being able to dial in the perfect 1/50 shutter with fine tuning in the 8 bit preset mode.

I've got an older build from july last year which allows me to do 25fps, 1/50 shutter and 3.0x bitrate. I'll just stick that on another card like zeek said. Was hoping to keep it all on one card but it's a small price to pay for the amazing stuff you guys have been doing.

Thanks
Dan

Just turn shutter range to OFF and you get a perfect 1/50 shutter.

I will upload a build which starts out with shutter range to default OFF. Shutter behaviour will work standardized.
Edit: done.

New build:
https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

- Added back Bit Rate and HDR functions. Stashed under Shoot tab(Movie tab is too crowded already)
- shutter Range default set to OFF(affects shutter speeds)

I am trying to obtain this field of view / resolution (yellow box) by setting the ratio to 'off' and lowering the resolution until I get around 1104x2484. However, I cant get past 12 FPS despite ML saying continuous recording is ok. Both resolutions are similar in pixel count but im having trouble understanding why the yellow box is unobtainable. This is in 5k mode. Can someone please explain, thank you!

Hi everyone. I have a problem using canon eosm and magic lantern latest BUILD "crop_rec_4k_mlv_snd_raw_only_2019Dec08.EOSM202"
I am using lexar 128gb 1667x sdxc memory cards.
When i am trying to shoot raw videos 2.5k or even 1920*1080 camera doesn't record a video it stops every time at the beginning because of the high bitrate > card seems to be isnt able to record a bitrate higher than 16 m/s. But after a several attempts to shoot at the speed 16-20 m/s card starts to record a higher bitrate about 45-50m/s but never at the beginning. Does anybody has this issue with eosm and lexar or other cards? Thanks for answers!

The card may not be original ... Sometimes it can be warmed up by formatting it. Sometimes my first movie is recorded with limited transfer and recording ends sooner. The next films are already ok.
