Yes, reproduce. Do you have the file somewhere?

Just test Dannes latest build. 1080p 24 and 48 fps are corruption free, and with nice preview , i think it's the best build i've tested. Only issue is that when fps override is on there is some vertical lines in video. But i don't think it's a big problem fore more users.
Thank you Danne for your work.

Cool.
Again. fps override will interfere with static set fps. What fps are you aiming for? I could set a preset for another fps, let´s say 25fps in the sub menu. Or you can also use reg_6014(decrease it) to achieve higher frame rates. Of course, the higher frame rate, higher risk for corruption.

I try to set it to 23.976 like an experiment , and saw that lines , but it's only visible in 2.35:1 aspect ratio , in particular use i think nobody will use that value on practice. So I think the last build is incredible. Eos m is now more usefull than first BMPCC .
Now i am waiting my focal reducer for eos m, and wanna try how it will work , it will be almost full frame raw camera

Nice. Yeah, it´s very versatile. Be sure to check out the x3zoom which gives a really nice tele resolution at 1x1 pixel ratio. Nice to use even for 48fps.

+1! I am looking mostly for 23.976 and 25.000 fps. If this would be possible via submenu, this would be cool for quick setup.

I really like this for focusing! Unfortunately this can't work for 1x3 mode.

Yeah, 24 or 30 is what I shoot most. But in this situation, tre most stable is all that matters.

Danne · « **Reply #2157 on:** February 11, 2019, 03:29:50 PM »

30 fps is probably not gonna work too good. 25fps more so.
For focusing masc? But x3zoom will also record in this mode. Are you after a tempory zoom function?

My biggest problem is, that I nearly never get correct focus on my EOS M. The 3x zoom helps a lot there. Yes I know, you can record with it too... (really nice! I like how easy it is now!). In 1x3 mode focusing is nearly impossible, because the realtime preview has wrong aspect ratio and is way darker (and green), so beeing outside I really see nothing on my display. Indoor I get it here and there...

Added a 25fps switch in the sub menu:

Will work with following presets when 2.35:1 or 16:9 is selected:
2.5K 2520x1418
mv1080p 1736x1158
5K anamorphic

@masc 1x3 real time view is preeeetty anamorphic. Better than nothing. Fixing it is beyond my horizon atm.

masc · « **Reply #2160 on:** February 11, 2019, 04:42:42 PM »

Oh thanks so much Danne! I'll try out this evening!

Yes, sure, I believe it is not easy. Maybe an idea: could it be possible to switch to "mv1080p x3" when halfshutter is pressed (when not recording) and to switch back to 1x3 when halfshutter released? Maybe doing so only if a option switch is set somewhere... just an idea... you can hit me now

Danne · « **Reply #2161 on:** February 11, 2019, 04:52:21 PM »

Yes might work. Problem for me right now it includes switching reg 800c. I don't see how to "fast" switch this register. Maybe a1ex has some ideas

masc · « **Reply #2162 on:** February 11, 2019, 06:15:46 PM »

Tested your new todays version: 14bit preview is already much better. Now I have some contrast on my screen! 25fps also works fine - so far corruption free. What a shame that exact 25fps is not possible with this reg_6014... but maybe nobody recognizes when using in projects... may I get synchronization problems when recording music videos for 3..5min? 0.005 fps is not much

Danne · « **Reply #2163 on:** February 11, 2019, 06:27:12 PM »

na, think your sync is ok.
We could probably refine this more but it will take some work...

OlRivrRat · « **Reply #2164 on:** February 11, 2019, 10:19:44 PM »

Is there some benefit to 25FPS vs 24FPS?

Danne · « **Reply #2165 on:** February 11, 2019, 10:31:28 PM »

Yes, you gain 1fps.

Let me just say, WOW. This camera has come a long way! Danne, I can't thank you enough for your contribution. I almost gave up on it, because of the frustrations I had with image quality and all the hassle of settings, but with this newest version (crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Feb11.EOSM202) I literally just installed, enabled the modules, and set the 2 presets to autorun. I am VERY new to this (hence the struggling with focusing in the videos), but these developments have given me the push that I needed.

Below is a sample of what I was able to get out of this rainy, foggy day. First two are handheld, second two are tripod. This was taken with a Canon EF 1.8f STM and the Commlite adapter. I just ran the MLV files through the MLVApp to get H.265 format MP4s.

Does this x3 zoom turn mv1080p into moviecrop mode?

Here in germany most TVs seem to work with fps numbers x*25 and use optical flows at 50Hz, 100Hz, 200Hz, 400Hz,...
I always feel it looks smoother if the clip has 25fps than something else. 23.x and 29.x always looks a little jumpi over here. But maybe those jumps are the cinematic feeling...

Updated white level for 10bit to following:
iso 100 white level 2840
other isos white level 2890

Tested against highlight recovery sliders in Mlv App. Could probably need some more testing. It´s also arguable if analog gain regs should be pushed a little to get closer to 3000 but seems it works good as is right now.

optical-work · « **Reply #2171 on:** February 12, 2019, 03:06:03 PM »

spent some time with today's build.

mv1080 with x3zoom gives me vertical jagged lines like 3x1 modes. so i tried manually activating x5 zoom and jagged lines are gone but also it says mv1080 works only x1 zoom mode.

i never needed to change resolution and aspect ratio in the raw video menu but when i want to get continuous 2.5k 16:9 setting. if 16:9 preset in crop mode menu could be a continuous setting like 1920x1080 it would be usefull.

4.5k anamorphic title at the bottom line of the global draw is a little bit long and it causes focus distance value disappear. it appears when focus ring is turned but that's laggy and usually no use. so the title might be shorter.

and i only have corruption with mv1080 48 fps x3zoom.

Cool @optical-work. All fixed!
Please recheck for jagged edges. No need for x5 zoom. As Levas once pointed out reg 8000 needs to be set to 5 and jagged edges are gone. Had forgotten about that. Also shortened name on global draw and added a 16:9 x5 preset(2192x1234). Let me know how it goes...

Edit:
reuploaded a new build. Missed a line.

masc · « **Reply #2173 on:** February 12, 2019, 07:24:42 PM »

Whitelevel seems to be correct now! Cool!

optical-work · « **Reply #2174 on:** February 12, 2019, 11:49:41 PM »

jagged edges are gone and 2192x1234 is even better. but focus distance isn't still there with 1x3 mode. actually i can't really complain because you already made focusing easier but again that feature comes in very handy especially adjusting the focus for infinity using these focus rings without hard stops. @Danne

there is also another issue with dual iso. i couldn't end up with a video that doesn't flicker when dual iso is on. i tried various iso combinations with still shots and moving camera and it always flickers without any color adjustments. tested 1x3 mode and mv1080 (in which i'm well aware of having smooth videos before). i'll try again tomorrow though.
