Some quick shots from yesterday, nothing scientific, just random lighting situations,motion cadence, and sound.  There is some stabilization on a couple clips, so if you see any quick jitters, it’s more than likely stabilization, the Jeep logo shot for sure has a slight bounce.  If you have any questions I’ll do my best to answer.
(A majority of this footage was shot with the 2nd newest build, not the updated scripts build)

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

Added x3 zoom mode through a set switch in the crop mode sub menu. Will work for mv1080p + the mv1080p 46/48 fps presets. Good for close ups. Stays coherent with ratio modes also set from crop rec sub menu:


I excluded 3x1 4k, 5k presets. Too much aliasing.

made some quick tests and it looks very good.
in mv1080p 44.959fps one damaged frame (16:9)

all other modes I've tested were without frame corruption.

I've tested the 2.35:1 and 16:9 presets.

the 2,5k mode is now somehow locked to 2.35:1, but I don't have to fps override to 19-20 fps anymore.

all recordings with sound and GD off (to be able to see the write speed)

did not test the 3 & 4k modes. and the new 3x-crop

5k mode without problems

Best thanks to Danne and others.

19 fps is for 3k 2.35:1.
2.5k is static 2.35:1 when set in sub menu otherwise not.
Corrupted frames to be expected here and there if not in 2.35:1 ratio.
Thanks for testing.

You know something funny... after years, I mean YEARS of not really taking a deep dive into LUA scripting and boy as soon as I installed @Danne's latest crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Feb07.EOSM202 build, THEN after loading all the Modules respectfully... and BOOM!

Lord & behold I first just simply go to the LUA submenu from within ML menu, enable both sd_overclock and the ratio 2.35:1 scripting magic. Honestly, that was just so beautiful to witness the work of yours, @Danne, governing thru my camera and I totally felt your presence right there. Just like Aliens, ain't that right @70MM13?  :D

After about 10 seconds or so is when it should all be enabled automagically and thus ready to shoot w/o the need to manually enable anything on under Movie submenu from within ML’s menu.. I mean WOW.. what more can you ask for from LUA? Ha.

Never seen anything as good as in ISO 3200 (even @ f2.8 which is a tad slow) and better yet in 4.5K is nothing short of absolutely ridiculous stunning images especially coming from this particular cam. Dual-ISO is indeed pretty gnarly to the very least!  8)

I've encountered something odd though (maybe you guys are already aware) but notice if one constantly goes into half shutter for to check real preview/focus while recording which then can get stuck into the real Live Preview after like 4th or 5th time (tho cropped slightly off center upward) and while it doesn't effect the footage. Well other than some of the corrupted frames -- not sure if it's related as I'll have to investigate further.

However, if you're more cautious and only use it like twice or maybe three times to check focus while recording per MLV takes which should help reduce the chances of getting stuck forcing you to turn off/on cam (Canon menu or ML menu in/out doesn't seem to do the trick for this). Just something to point out before I forget.  ::)

As far as corruption-free footage... I would say it's about 70-80% more or less corruption free for me (see video below) while only shooting in 4.5K ANAMORPHIC @ 2.35:1 in 23.98p and is probably most likely due to my SD card being close to full from earlier tests (forgot to format card).

I even went ahead and deleted a bunch of files from within File Manager in ML (good thing we have this ability just imagine while we're out on set w no computers). Anyway, just felt the need of writing this up before I pass out in bed with these thoughts without sharing.  :P


Can't wait to get my hands dirty on this tiny beast for some more in depth testings (Got few ideas of how to show which way is it cropped slightly off center per certain settings as I suspect some if not all seems to be different from one another)... Hopefully this weekend and Thank You, @Danne!

Thanks for kind words deafeyejedi :).
Could you check if this versions is less prone to get stuck in real time liveview?

Great @gravitatemediagroup
Put up some videos in there :).

@deafeyejedi
Didn´t see the video before but it looks really cool. No aliasing, pretty amazing. A little worried about the pink frames you are getting. I have been using the anamorphic 2.35:1 mode for a longer period and couldn´t get any corrupted images. Well maybe one or two. Really shitty issue. Would be such a relief to fix that completely.

Thanks! Had to post it for others to understand where we are coming from. Heh.

Also test shot some more extremely low night scenes earlier tonight in Dual-ISO and I’m really surprised w how clean the shadows can be even when pushing the exposure level up to +3.00 or +4.00 within MLV App while pulling down the highlights w ease.

I wonder if the ISO-gain experimental builds from you is what makes it look cleaner or have I been smoking’ the wrong reef? How do we go about to ISO 109? Ha.

Ya it may be shitty but again it’s not exactly a deal breaker. Seems doable. Not every take has corrupted pink images. I’m hoping this could very well lead us to a pattern and eventually we’ll find a way fix this.

Lemme try some more this weekend w few fast SD cards (280 Mb/s) I know I know it’s a bit overkill but it wouldn’t hurt, right? :)

That's some pretty ace video...  The initial closeup of the cat was stunning.
What's with this miraculous camera?  Who needs a 5d3?  :P

It's getting hard to keep up with all the progress lately!

Exciting times...  Keep up the great work everyone!

I get those lines especially when overriding Danne's presets with fps=25.

Overriding fps is problematic when statically set. What you could do if you only want to push it from 24 to 25 you can decrease reg_6014 until it reaches 25 fps.
Otherwise those lines will appear when bitrate is lowered and liveview register is compensated to increase brightness. All is done though round tripping. At least the footage comes out ok looking...

Something to share with you guys... Here I've put together some of the shots from the wedding filming I did for my friend. It's nuts how good the video looks, I'm really happy with the result, even tho it's sometimes a little difficult to focus some of the shots.
And that slow-mo in RAW, that's a dream coming truhe, heh  :o ;D

Outstanding work Danne and others!

Thanks Joni! great stuff.
Still some pink frames to fix I see for the build to be perfect but I must say 4.5k looks very cinematic.
Thanks for sharing.

- Liveview will show a clean 14bit preview while not recording(previewing mode). As soon as you hit record liveview change according to bitrate chosen and analog gain registers will kick in.

Thx Danne, using this register picture looks way better - whyever. Maybe a little less noise - don't understand, maybe my test conditions are not perfect...

@Jonit: great video! :)

Not sure how your footage is affected but when reg_6014 is used you change the reg directly in the preset.
I have set all presets on 2.35:1 to 24 fps as we need the speed and that's also what I use most of the time but 25 fps should be working too for most presets.
If footage has artefacts when using fps override it might be a conflict with power timing registry.

Thanks, @OlRivrRat! Will get back into SL1/100D soon.

Something to share with you guys...

Indeed, great stuff @Jonit -- pretty impressive footage especially coming from an 18-55 IS STM lens. Maybe I should pick up one? Ha.

Also If you don't mind me asking how come you chose abnormal ISO settings (i.e. 400/3200 or even 3200/400) for Dual-ISO footage?

I def gotta get my hands down w this slo-mo 3x3 binning in 47.991p which speaks volumes about this tiny cam's potential. Thanks for sharing!  :o

And as always. When using 48 fps turn off global draw for best performance.

Thanks guys!

@DeafEyeJedi - regarding DualISO settings, it depends on the lighting conditions. During the day, I aim to expose for the highlights with a base iso (e.g. ISO 100) and then I choose recovery ISO a couple stops higher (in this case it would be 100/800). Let's say that I'm filming indoors where is a bright light coming form the window, but there is also an artifical lighting (like in some of the beginning shots), then I would expose for the window (ISO 400 in that specific example) and set recovery ISO to 3200 to "light up" the remaining indoor scene. It works quite nicely I would say.
Sometimes I do it the opposite way, where I film at ISO 3200 and set the recovery ISO to something like 400. I guess it works both ways.. If I'm wrong then correct me please.

And yeah, that 48fps is golden. I like the fact, that on some of the shots (with not much rapid movements), you can slow it down even further with something like Twixtor or Optical flow and not get much artifacts. Pretty neat!

-regarding the 18-55 IS STM lens, I like that lens very much. It's neat and tiny and OIS is great. But what I like the most about it are the flares it produces when shooting against direct sunlight. Beautiful greenish flares. heh  :)

Regarding 48 fps you can try shooting 50fps by decreasing reg_6014 until it reaches 50fps. I think dail down to -50 or so. It´s in the sub menu. Also test the latest build and check if it works any better regarding corruption.

Those vertical lines were visible, but scouts honor I didn’t adjust fps override.  I’ll see if I can recreate the issue with newest build, but so far I haven’t seen anything of it.

Yes, reproduce. Do you have the file somewhere?
