Camera-specific discussion / Re: Canon 7D Mark I
« Last post by domo94 on Today at 12:49:47 AM »
I'm just the worst with code.
I have bare minimum knowledge.

I know you've posted the resources before, could you point me in the right direction on what I can to do contribute?
The basics I need to learn, any programs to download?

I'm great with numbers / patterns.

Did you have any artifacting, skipped frames, Magic Lantern freezing on you, or tons of moire with it?

What's your max iso shot at?

How's the noise and grain?

General Development Discussion / Re: Dealing with Focus Pixels in raw video

I've implemented vertical and horizontal spline interpolation in my monster program. Seems to work on dualiso dng too. My next step would be make it able to write back(or into copy) changes into dng.

Below picture is a difference between corrected and original values. No change is 0, on focus fixel coordinates it's something else.
Playing with exposure to make it visible to humans:

This was from 10bit anamorphic footage. Gradients everywhere. Maybe interpolation is the only sensible way to correct this.

Did a comparison of 3 presets: regular 1856x790, 2784x1160 and 4064x590.
Before shooting i zoomed with the lens according to the crop factor of each preset.
Critically focused each time.
Lens: Nikkor 70-210 f/4.0
Aperture: 5.6
Iso: 400
In MLVP i set the saturation to 0, exposure to +3 and chose Blackmagic profile.

The whole images looks like this:

1856x790:

2784x1160:

4064x590

Zoom in:


2784 one came brighter than others, so let's level them by brightness:


4064 is my favorite although it has a lot of artifacts including a bit of digitalizing effect because of squeezing. But it's sharper than 2784 and has less crop factor, so it's more cinematic.

 PS:
@Reddeercity
You said that the image is centered in 4k now, but look, when you set 9 and 34 with your latest build it looks like this:

And if you set nothing:


When did the cropmark I was using this latest build.

What card? Did you test the latest build from my bitbucket download section?

Gotta take a look. Hm, now when I think of it. Didn't you fix maps for 100D a while ago? Memory failure.

Don't know what your needs are but my favorite native lens is still the EF-M 11-22mm. I recently got an EF-M 55-200 because the EF-S 55-250 with the EF to EF-M adapter is bulky on the M50. Those two lenses plus the 15-45mm kit lens cover most of my needs. Yeah, they are slow lenses but I'm getting a bit slow myself. Well, the image stabilization helps with that.

There are several EF-M lenses to choose from and lens adapters will give you a wide choice of lenses you can play around with, like this old fast Nikon glass that could be interesting when combined with the in camera image stabilization feature for video on the M50.



As far as when all of the ML features will be available for the M50 -- don't ask!

Pixel maps don't work I think.

If you think they don't work, send me a short MLV file so I can check it out.

Well, did you test yet OlRivrRat? What card are you using yourself? If you test run the lua cinema script and record in anamorphic 2.39:1 for the test.

Might be helpful to let us know what SD that is ~
