Now that you bring it up--I would prefer if the default fps on the bleeding edge settings could be set to 23.98 instead of 25fps. Yeah, I know that we have users in PAL land and NTSC land but pretty much all film production these days is being done at 23.98 (even if they tell you it is 24). In addition, it does allow for just a tiny bit more max resolution than true 24fps.

It's been default 24 fps for a while now although 25fps is to prefer often here in pal country. Flicker frequencies and such.
@Hek
You can use shutter fine tuning instead of fps override.

Danne

I tested your last build today. Very nice!
Still get some occasional pink frames. Can't narrow down what's causing them.
The statistics from today is:
5K anamorphic
1136 x 1918 - out of 5 clips 2 had pink frames - 1 and 2 in each
1184 x 1998 - out of 5 clips 1 had 1 pink frame
new 4k anamorphic rewired
1136 x 1900 - out of 3 clips no pink frames

BTW, what's the difference between these two presets?

Will do more tests tomorrow. I film some clips in LV and others in LV with GD off and yet others on non LV mode, maybe this has influence.

Thank you!

The most trusted way is to run the lua cinema script and record 2:35.1 ratio. If you also enable Kill global draw setting I think youll have a hard time getting pink frames.
Other settings could work and could not work.

I see, I'm a 16:9 guy, so this script won't work for me..
Where is this Kill global draw setting?

Ok, Thank you, found it, will test tomorrow.

I've noticed that your build is so smooth and responsive, feels great comparing to my 6D, which feels a little sluggish. Also things don't seem to break, at least I haven't been able to break anything so far, which would require a reboot.. So, congrats, feels very polished.

About pink frames.. I though they were caused by corruption that occurs when a camera runs out of processing power and can't keep up with the data flow or recording it onto a card.. But my observations with today's footage don't seem to support this.. I observed pink frames in places in my footage where I would expect them the least if my theory was correct, like I pan the camera from a brighter spot to a darker spot and a pink frames occurs in the dark spot, where, according to what I've read, the data flow should be smaller.. Strange  ::)

Could be timer regs, compression code, cpu or a mix of things. Who knows. It's a real pain in the ass, that's for sure...

If it's of any help.. I don't think I ever got any corrupted frames on my 6D. I get 2nd and 3rd frames corrupted all the time, they are practically never good, but apart from that, I can't remember ever getting a pink or mangled frame.

No help here i'm afraid. I must say I feel lost when tweaking regs. Shooting from hip, testing comparing until I tested all I could think of testing.
At this point I think a1ex could take a look at my anamorphic parts in crop_rec.c and maybe he sees something that can be refined.
What you can help with is tweaking following regs straight in crop mode sub menu:
713c
7150
6014
6008

Maybe you find a better combination for 16:9.

Ok, I will try these.

So, the 6D and EOS M have different values in these regs? Can't take them from one put in the other?

If you ever wondered why it takes so long to get ML ported to new hardware or even to new firmware versions ...
And some cams are worse than that. My 650D won't work with Dual-ISO without tweaking a value which works perfectly well on other 650Ds.

Not the same @baladev. They follow the same relation and they are named the same. A1ex got them all pretty much figured out. Should check his bad ass crop_rec.c for 700D...

Speaking 650D Walter. We should get that one too into anamorphic world.

Sorry, unable! I'm pretty sure I'm occupied with other things until April 2020.

I could prepare a preset for testing. Let me know if any interest here 650D users...

As long as we're moving off topic:

My 650D won't work with Dual-ISO without tweaking a value which works perfectly well on other 650Ds.

Happens with some 700D's too. For the new crop_rec settings, these two cameras are so similar it might just be a matter of using the registers we already found on the 700D on the 650D and Bob's your uncle.

Danne! Tried out your newest build with the 4k anamorphic rewire - Does that mean that the live view will match the framing, you see realtime what you get? If so i cant get it to work. Any tips? The regular 1080p MCM rewire works perfectly though. Thanks!

Try the last build 4k anamorphic rewire awesome but framming in real-time is taking the top of the frame , it will be cool if there is some possobility to make it more centered.

Danne

I did some more testing to try to establish some pattern in pink frames.

Used your latest preset 4k Anamorphic rewired @14bit, 16:9, 1120x1890 res.

1 In LV with GD on I got this
clip 1 1m30s - 10 pink frames
clip 2 1m12s - 13 pink frames
clip 3 1m7s - 10 pink frames
clip 4 23s - 4 pink frames

2 In LV with Kill GD on I got
clip 1 1m30s - 0 pink frames
clip 2 54s - 0 pink frames
clip 3 50s - 0 pink frames
clip 4 50s - 0 pink frames

I also ran tests with your 5k anamorphic preset. With Kill GD enabled, out of 10 clips I only got 3 pink frames in the first one (maybe some settings didn't update correctly?), all other were pink frame free.

Not sure if this info is of any value, but could it be that GD somehow contributes to PF effect?

Another thing I noticed is that in 5K preset video 'jerks' often. After watching clips for a while I started noticing that it happens when the camera changed direction of movement. I think it might be related to IS not working properly in this preset? In 4k preset I didn't notice any jerkiness. Sorry if this is known or has already been discussed.

Kill global draw is there for the reason giving som more overhead.  No more tests needed since those issues are already stated many times. Run 2.35:1 for pf free frames.
A helping test is if you could refine your preset tests by changing the regs I pointed to before and compare results.

I use mv1080p and then crop.This creates moire/aliasing free footage much more details than mov h264 and colours you never suspected this camera could capture.

What is the difference with using only movie crop mode (without mv1080p). Or do you use mcm rewire?

Hi Danne,

Got the latest build (11 April) and saw the 4K anamorphic rewire.

Just wondering if this preset was hooked up yet to get a real-time, proper framed preview.

I’m well aware that it’s probably a long shot, but I got excited when I saw the preset name.

If it is hooked up, could you share some working settings as I could manage to get a good preview without framing on, which is similar to previous builds/presets.

Not trying to be demanding, just got excited by the name. If there’s something to help test:try just let me know.

Thanks

This is the difference
First picture shows the 2.5k preset
Second picture shows modified 4k anamorphic preset
Lens used was a mount-c 12.5mm f1.7
With the first one no continuous rec, but with the other

Thanks to Danne, used the recent build
2464x1418




I apologize for the motive, this is 960x1900

Now i use rewire mode cause i had problems removing focus pixels, higher resolutions in anamorphic mode will give you lot less aliasing.
