I wonder if this gets mentioned in the thread. If I boot in anamorphic mode, the live view first shows up in seems correct aspect ratio, and then after about one second it gets stretched.

Now i use rewire mode cause i had problems removing focus pixels, higher resolutions in anamorphic mode will give you lot less aliasing.
Mv1080 rewire gives me way too much aliasing. Is there a difference between just moviecrop mode and mv1080 with moviecrop mode?

Just test it and compare

I am using the 9 April night version, in 4.5k the 1502 x 1920 resolution has disappeared for some reason? The 14bit lossless data rate with correct exposure amounts to more than 70MBs, using ettr 90 or more of it ... right so? I'm working with sandisk pro 170 card in reading, the maximum speed at which I arrive is 55 and maximum 60/61, someone else has the same results? Thank you

Is there any way to center the live view after running the included script? When looking at the live view, I only see about the top half of the framing preview. It's not a problem if in static shots, because I'm able to use the framing preview and then just hit record. But when I'm trying to film moving shots or frame my dogs in a shot, I can't ever get the shot I want due to the way the live view only shows the top half of what is being recorded. Am I doing something wrong?

Gentlemen, please read this thread starting with page 71 post 1765 to familiarize yourself with the limitations/quirks/oddities of ML implementation on the EOS M. Answers to most of your questions contain there. I'm doing exactly that the 2nd time now to fill in the gaps I missed the 1st time :)

I don't see a difference that is why I asked if you had a reason to use mv1080 with moviecrop. Maybe you had a reason..

@henricusmaria

Normal mv1080 has stretched LiveView, mv1080 with Move Crop mode rewire has correct real-time LiveView.

Consider using the latest build from Danne, some of previous build has Extreme Moire when using MCM rewire, in the newest ones the problem has been fixed.

I see now in recent build realtime preview looks properly alligned like "Framing" preview.Great work Danne!

I'm confused, what are the statistically more stable resolutions that allow me to record continuously with a real-time display at least in black and white? Due to lossless compression I find that the bit rate increases up to 60% more, you have the same result?

Run the cinema lua script. All presets should then be lossless. If you also enable Kill global draw in RAW video menu chances increases even more. If this isn't working, check your card. Should be able to pass 55mb/s write speed.

Great Danne, my card arrive at 60/61-2 MBs. unfortunately with the high resolutions as soon as I exposed the signal correctly the bit rate rises to 80/90 MBs

Then you probably didn't run the lua script. Please do a screen recording of what you're doing otherwise since a lot of information is missing now.

Still need to see from start to finish with a clean build what's going on. Also, what's the exact name and spec of your sd card?

Sorry Danne, I was talk about 9 april. I re test with the 11 april version, I think much better. My card is sandisk extreme pro read 170 MBs.

the only certain thing is that with 14 lossless, exposing to the right also increases the bit rate by 60%

@marcelolippi Make sure you have no clipped highlights. Picture should be a bit underexposed to get the best result, especially if you have large bright/white objects in the frame. GD causes pink frames in crop mode, so unless you don't mind them, use Kill GD, of course then you won't have LV and no framing, if you need framing, afaik your only option without pink frames is MCM rewired preset. I also reduce audio sampling to 11KHz, this helps to give more room for video. Tonight I was able to film two clips (~12min each) clips of band performance with 1120x1890 14bit anamorphic (used 4K preset). It was dark, in daylight it won't give me continuous.

I have the latest build. Mcm rewire still gives aliasing/moire. Using only Movie crop mode gives me cleaner footage. My question was if there is a difference between using just movie crop mode and (standard) mv1080 with movie crop mode.

@henricusmaria

Movie Crop Mode will give x3 lossless zoom and it uses small area of the sensor 1x1 sampling, in mv1080 you are using the entire sensor 3x3 sampling same as MCM rewire. I don't know why it wasn't clear enough,  have you tested the two mods before?

The aliasing and moire come from the line skipping in 3x3 sampling, to get rid of that and if you want to keep crop factor 1.6 or close (like 3x3), use 1x3 sampling as known as 5K Anamorphic.

I know.. again, I was responding to what 2blackbar wrote about using mv1080 (no mcm) and moviecrop together. This way you are not using the entire sensor.

I think  crop raw records 5x5 not 3x3(had to disable it to record 3x3), so you can force it to record 3x3 (kinda like normal h264 3x crop area) but real noalias mode is 5x5 from what i understand.
I actually tried both 3x3 and 5x5 raw and i prefere 5x5, 3x3 looks a bit artificially upscaled to my eye but that might be my lens resolving power not being good enough.
MAin reason i use mcm rewire is that i can remove focus pixels with it in mlvapp and i cant with regular mv1080, they both looked similar to my eye and mcm can record full sensor which is super amazing.

So i've just installed today ml on a eos m (after messing with a 100d), I've been testing it and reading the thread. I've been using it in my room, tomorrow I'll take it to the street with daylight. My question is about the resolution of the 4k and 5k modes, for what I'm reading it records in a resolution lower than 1080p and then it gets upscaled when exported to dng, is it then a fake 4k/5k?

It records almost two times higher than 1080 -  height is 1900 pixels but width is upscaled later from 1488 pixels to 4464 to match aspect ratio.
dngs are actually 1488x1900, final res is 4464x1900.You can round it to 1920p.
I suspect these are highest resolutions cam bufers can provide at the moment in this combination.Highest width without 5x5 crop is 1736 pixels.
Its the best possible quality that you can get from canon M and its amazing that it even works.

Well, 4k (uhd) is 2160p, so it gets pretty close, I guess then this is better to use this than using an h264 4k camera (like a lumix) due to the options in post-processing and color, right?
