MLV App 1.14 - All in one MLV Video Post Processing App [Windows, Mac and Linux]

[Giovanni89]

Hi everyone. I’m following this discussion with great interest. Please apologize my English, I’m still learning. So please feel free to correct me anytime. I have two answer about this wonderful app:

1) I always used the “regular” and bloody slow workflow with camera raw ecc. but when I switched to mlv app I immediately noticed that everything appear less “definite” and “clear”. As if there is a thin veneer on every single frame. Do you know why?

2) is there any chance, also in the future, to use this application on the iPad? It would be perfect for me.
Thanks

Thank you very much for develop MLV producer, many scenes of my documentary were impossible without 3.5X.

...for develop MLV producer...

Wrong thread, here is MLVApp.

... were impossible without 3.5X.

What is that?

[ilia3101]

Does anyone have a raw video or photo with blue/violet light that clips in an ugly way when you process it with MLV App or any other software? If you do, I would like to see the file. Any camera make/model will do, preferably large sensor tho.

something that looks like one of these:

And if you have clipping colours other than blue/violet, that would be useful to see as well.

Thank y9ouu!!!

Here is one file:

Set wb to 2400 and get this nice blue tones:

Here, 5D2, the lamp is actually completely blue.

Interestingly, clipped highlights can still be somehow fixed on the first video using reconstruction.. But certainly not on the second video..

[ilia3101]

Oh yes cyan is useful too, thanks for finding that one again.

Still looking for blue/violet samples, especially with blue and violet at the same time

If you need the same with any other setting, or recorded with the 5D2, let me know... (this is 5K ana. rewire @ EOSM). The blue LEDs bring so ugly nice artifacts...

MLVApp:


Edit: ACR: (also not really better)

[ilia3101]

Very nice clip!!! It even has some violet going on in the foreground! Thank you

Here is two samples , let me know if you need more

1
ACR 3200K


MLVApp 3200K


2
ACR 3200K


MLVApp 3200K

Omg I lovve you! Great samplels plus I really wanted an ACR comparison. Great to see where we are both at. Soon MLV App will be destroying camera raw in this comparison.

1. In the profile section, try the "Reinhard 3/5" tonemapping function, you might not like the very smooth default tonemapping, which gives very cinematic highlight rolloff but is kinda flat looking.

If that does not work play with the dark strength and light strength sliders, adjusting the curves or using contrast slider. Or set gamma in profile section to some lower value like 2.6.

Thanks

If Qt compiles on iPad, but then iPad has no real file system so that is probably quite difficult to adapt for. Something more realistic is getting it working on Android tablets.

Pretty much no, sadly. Unless an iOS expert steps in.

[ilia3101]

If any windows users are having issues, try the 32 bit build as well.

[Skinny]

Yes, I want to say thank you to Ilia3101, my problem has been solved.
This is very important guys. If starting from version 1.8, the program crashes when loading a mlv file, try the 32-bit version.

Now I just have to learn all the new features

Thanks to all who contributed to the creation of this program, for this wonderful app!

I don't think so. With Qt we should be able to compile for iPad, yes. I just don't know if the standard C processing code can also be compiled. Is there a ffmpeg for iPad? (I guess not.) And Apple wants to be paid that we develop apps for them (we need to pay for a dev license). We can't sell the software with GPL license.
On the other side, we know how slow MLVApp can be on PC or Mac. An iPad is way slower, so I think it is not really worth it.

On Android we would not have the license problem. But the CPU power problem is the same. With reduced functionality it might be good (as a kind of viewer). But as processing app you'll need a lot of time...

[Lars Steenhoff]

If you pay apple for a dev licence this does not men the app has to be payed as well.

There are many free apps on the App Store.

And the latest iPad is faster than most laptops.

But the other issues are still there, ffmpeg etc.

[masc]

Yes sure... so you mean to pay apple with magic lantern donations? But we also have to pay for a place in the AppStore, right?

And the latest iPad is faster than most laptops.

How can this be compared? App on iPad vs. emulated iPad-App on Windows? Sure... iPad wins since the first day. The processor has a very different architecture, so this should be hard because of the lack of corresponding applications.

[Lars Steenhoff]

I have a apple dev licence, but that's the least difficult part ...

When compared to intel cpu the race is close ( in single core )

[masc]

I think the app also would run much more in single-thread mode, because there won't be OpenMP for iPad / Android. Or?! Edit: for Android it seems to exist.

You can't compare geekbench scores for iOS to desktop CPUs, it's not the same.  Apple would like you to believe that, but it's a lie.  My desktop draws around 100W if I have the CPU at 100%, and I can add more than that again for the GPU, which MLV App uses too.  If your phone used 250W it would instantly burst into flames.  Phone SOC draws about 5W?  Image processing on a phone or tablet is going to be slooooooow.  Might still be good for some limited tasks.  Does not seem worth the hard porting effort to me.

More samples here Ilia (shot with 50D), they might be useful because they also have skin tones in it. If there's anything else we could help in enhancing color processing on mlvapp, let us know:

That's what I think too. Little correction: MLVApp don't uses GPU (apart from some OpenGL for viewer dragging and zooming).

[Lars Steenhoff]

I think you will be surprised how fast the mobile cpu/gpu have become recently

its good enough to edit 4k footage with effects on top

And I use lightroom mobile to edit dng stills, I tested and even cdng works in lightroom mobile.

[ilia3101]

Mobile devices have special chips for decoding and processing video (and for doing all kinds of things), plus GPUs are always powerful these days, even in phones, an OpenGL fragment shader could do most of what MLV App does in real time. You just have to program stuff differently to make it fast on an iPad compared to a intel cpu, which would be a lot of stuff to re make in mlv app.

Id love to have some app on pxel that has tonemapping exactly like You did it in MLVApp.When i shoot RAW on pixel i always conver in MLVApp because of tonemapping.
Is there a new version in repo with some color fixes for cyan and magenta ?
