Clean format of KB1066x CF card in mac to exFAT
Clean re-install of previous 4K_crop-rec Danne build 2/4/19 on SD card

All seems restored and working – except for one shot which didn't respond to stop button. Restarted camera, shot a few more tests at various res. All import working into MLVApp.

Tried a different Sandisk Extreme CF card with current state – all is well.

Totally weird!  :o But very happy my camera is still alive! :)

Still very unclear but I would say nothing is wrong with the ml builds. One thing is for sure. I would never trust that KB card.

It's been rock solid til now – but today I'm starting to wonder…  :(  I had a Lexar before that which was a pile of poop!

Try a windows formatting:

Seems different card readers can affect too. Doesn´t really matter that it worked perfect until today. Suddenly issues starts to happen.

Didn't know that – interesting! Will look into it, but I need a PC!

Does anyone know when formatting on mac whether the eXFAT scheme is crucial? (e.g. GUID, Master Boot Record, APM)

Sorry, haven't much time (and it doesn't look like I can help).
Formatting with ExFAT will enable Exfat on low capacity cards where Canon's firmware denies to apply Exfat within its own format routine. A1ex has a patch for it.
But I'm afraid it will not rectify the situation with given card. I had CFs going south without rhyme or reason. No expertise in flash CPR, sorry.

Hey @andy kh with below mode you can do 45 or 48 fps mv1080p depending on if in 50fps(pal) or 60fps(ntsc) mode.
1080p45/1080p48 3x3

Worked before with 48fps 1920x1080 but reverted back to 1920x1040 because om pink frames.

Posted two new builds:
https://www.magiclantern.fm/forum/index.php?topic=23041.msg216899#msg216899

Mainly I separated 45/48fps modes into two and they run in either 50 or 60p mode. Upscaled 48fps to 1060p:

@danne  problem wit 45/48fps is the live view. If i set to real time framing is not correct and if i set to framing live view is not in real time so very difficult to shoot a moving object in practical.
If i increase the fps in 1080p mode i get real time preview wit correct framing. There may be a way to increase the fps beyond 40

@andy kh
Thanks for report. Found the issue and now fixed. New builds posted just now:
https://www.magiclantern.fm/forum/index.php?topic=23041.msg216899#msg216899

Commit:
https://bitbucket.org/Dannephoto/magic-lantern/commits/178845d7d86e8b078a0d1345e05f4e35ee209fb2

Do note that preview will look a bit greenish because of the workaround to get bitdepth reduced with analog gain regs. Shouldn´t be almost black anymore though and image files will look good.

the live view gets much darker as soon as i hit  the record button making me difficult to shoot outdoor but not completely black anymore

Well from now on I expect some deeper feedback and testing. I will check into it myself som more though. I do see some extra greenish stuff happening. WIll look.
MAny of the presets can be run with the ordinary implementation of bitdepth changes so if that´s the case it will solve workaround issues.

very strange as framing in real time works only in ntsc . i have been testing in pal. today i tried both and found that framing in real timein pal is not correct

Are you referring to 45/48 fps presets? They are not gonna show the correct full mv1080p real time live view. They will behave the same both in pal and ntsc so don´t know what you are getting. Please film your screen or do more tests and explain further in detail.
Real time limitations known already since building the preset being in mv720p mode will yield faster fps.

now i understand
i tried in 60p and i get 1920 by 800 whereass in pal i get 1920 by 818 so in 60p the bottom is crop by 18
and its very near to what i see in real time
now i can get exact framing in any mode by goin to reg_skip_botton and increase the number by 350

Well increasing reg_skip_bottom also removes resolution.

Uploaded two new builds. Fixed some testing stuff I forgot to erase which affected mv720p modes.
Trying to fight the greenish tint but the regs I use for this on eosm and 100D is not very effective on 5D3. Will take a deeper look into this when I can.

Is it already possible to use magic zoom in full screen mode on 5D2 ?
