Hi all! This is a little video I did to accompany a tune I recorded.



Shot in raw on the EOS-M with Dane's experimental build.
The lens is a Weltblick 135mm f1:2.8 that I got for around £20 in a charity shop.
In MLVapp I used the cinematic 2 filter, and also sharpened a tiny amount as the lens wide open is a bit soft.

If you or someone else could check all presets for bottom red lines it would be good. With and without ratios from crop rec sub menu set. Lack of time here. Open up the files in Mlv App and simply zoom into the file, scroll to bottom...

I just quickly went though the presets, without the crop rec ratio then with it at 2.35 then at 16:9
Only found a line of noise at the bottom of the 2.5k preset with ratio 2.35.
But then again, I think I fudged up something. The sizes selected don't match the clips I got. I only had crop_rec and mlv_lite loaded, do the presets rely on lua scripts or sd hack?

Also, there's always a black line at the bottom of the 1x3 preset but is that because of the resize in MLVApp?

@Danne
yep, clear overlays does the trick, cheers!

@optical-work
I see. Here, in 1x3 without dual iso, chroma smooth definitely makes the focus pixels less visible but they don't totally go away.

when i use dual iso with 1x3 preset, mlv app chroma smooth settings doesn't fix focus pixels whether or not fix bad pixels and fix focus dots are turned off. tried with different iso values on 2019Jan20 build.
Same here even without dual iso. I s'pose it's a matter of new use, new focus pixel. If I understood well, dfort could look into this once we know which settings work reliably.

Shot a few 30s clips in 1x3 with the jan20 build and no corrupted frames! Didn't try dual iso because it didn't seem to crash as much with overexposure (still a bit tho).
Very handy to have the half-press live view for focusing! Framing view does break every now and then (just doesn't come back after half-press) but disabling then re enabling raw video brings it back.
Also found out that raw video needs to be switched on BEFORE running the sd overclock script for it to work. Might be obvious but it took me a mo to work it out.

This is very cool stuff, the image quality is bonkers and it's getting more practical and usable by the day. Thanks a million Danne!

Man, I can't keep up with this frenetic development schedule  :D
I tested the 1x3 mode in dual iso with the 14jan build (reliably corrupted frames), then the 16jan build and had no corrupted frames but had to be quite underexposed for it to be continuous. On ML's histogram I have to leave between two and three columns (EV?) on the right empty.

About dual iso processing in MLV App, is there a sure fire way to bring the shadows back, like say +1 exposure or +X shadows, or you just play it by eye?
Also, sometimes I do get some kind of flickering in the shadow/midtones, exactly like @loknar has in some shots of his windy winter day vid (great footage btw, shame youtube compresses the hell out of it. Maybe uploading in 4k...?).

Gonna try today's build tomorrow (by which time it will be totally outdated  :P)

Right right right, that figures, cheers for the explanations guys!
Gonna follow those instructions and try dual iso now.

Last night I could get continuous (at 1x3 1504x1920 10bit 24fps, with a handful of corrupted frames) but I was a bit underexposed the whole time.
Trying again in the sunshine, it crashes after just over 15s when I'm exposing to the right or slightly overexposed.
To test this, I started a shot underexposed and it rolled without problems for over a minute. Then pointed at the sky (to be massively overexposed) and it crashed within 200 frames.
Maybe I'm jumping to conclusions here, might just be a coincidence.

im not getting continuous recording with 10 bit 2:35 1504 sd hack setting only like 2 seconds and crash.

You mean in 1x3 right? Cos here it seems to work, I shot for a minute (but got 4 bad frames).
#10
Oh boy this is exciting! This afternoon I managed to get a bit more than 200 frames in the 1x3 mode at 10bit/20fps and came to the conclusion this is the best image quality (without mad crop). Now a new build with a way to do continuous 1x3!!! Man, you rock! Trying this stray away.
#11
Okay, sorry for the stupid questions, answers were in the thread..
Experimented some more with the 1x3 preset and it's so cool. Only getting a couple of seconds before it crashes but boy, they're good looking seconds!
@ctfire yeah, the shutter speed was a bit weird for me too, it seems to randomly set itself to 1/35 or 1/80 when changing presets. How many fps are you shooting at?

Hey guys! happy new year and such.
Been playing around with today's build and 2.5K preset script (and sd card overclock). The max filming time seemed really dependent on the exposure. Underexposed goes on and on, but ETTR and it stops after less than 10s. (more data i take it)
I accidentally managed to get a good shot with 1x3 mode and the result was super awesome!
Tried to get 5K going but without an automated script I tend to mostly mess up the settings and lose the live view (garbled pink stripes) and have to delete the settings folder to get anything working again.

I'm wondering, does the 2.5k-10bit-XXXiso lua script actually change the raw bitrate to 10? mlv_play shows 14 bpp.
Also, is "framing" view available in 2.5k or is it just for 1080mv?
Cheers

I've been trying to reproduce the cleaning sensor bug but it's pretty random. Here the few variations i came across:
- with only mlv_lite and mlv_play loaded, switch on and press play to start watching the last raw video then switch off whilst the file is playing. Every time it stays stuck to Cleaning sensor. Pressing the power button brings the camera back on and pressing it again switches it off immediatelly, skipping the cleaning sensor part.
- with snd,  crop_rec and lua also loaded, switch on, run the 2.5k 100iso script, shoot for 3 seconds then after waiting a bit, press the play button. If a bug shows up it can go two ways:
  1) you get a black screen. The orange led blinks as if mlvplay was playing the shot but the screen stays black. Pressing half shutter brings back shooting mode. Pressing play again plays the video without problem and it will not get stuck during Cleaning sensor even if switching off during playback
  2) the raw clip plays fine but when switching off whilst playing it gets stuck. The power button switches between shooting mode and cleaning, but the battery has to be removed.

I managed to get the last type 4 times in a row but then it didn't do it the fifth time. It looked like it happpened more often with the 2.5k100 than the 800 one but that might have been by chance. Also it did happen whilst mlvplay was stopped, and once whilst i was in a ML menu.

Just popping by to say Thanks!
I'd tested raw on the eos m ages ago and at first got crazy excited by the image quality. But I ended up sticking to h.264 for filming because of the very limiting crop factor, the headache of setting everything right in ML and I wasn't getting very good results in low lights. All that, added to the extra workflow in post, didn't make it seem worth the effort.
Now, trying out Danne's latest build, I'm crazy excited again! Once I'd cleared my saved ML settings it worked perfectly, just switch on, run sd hack and apply a 2.5k preset and it's all good to go! 2.5k is a lot more workable than 1.4k and with the 800iso preset low light shots aren't as noisy as what I was getting before.

So thanks a million to everybody working on this!

I haven't read all 71 pages of this thread, so the following bug probably isn't specific to this build, but just in case:
After going through the steps I described, filming a shot in raw then reviewing it in-camera, when I switch the camera off it gets stuck at the sensor cleaning stage and never switches off. Pressing any button brings the liveview back but taking the battery out is only way to switch off.
