Composite CGI to resemble iPhone footage | Blender & Nuke

[@hasselhoff3379]

I love your channel and the videos are really entertaining. I have a couple things that might be worth mentioning: At 51:50 you would need to use an ocio configuration with the agx viewport transform. The render is linear and so is the exr, the viewport transformation only applies in the viewport or when you bake it into the image/ video. In your case you are using the Nuke default configuration which is terrible (and even the iphone isnt that bad) and I think that using Agx and then degrading the color gives you more control. Auto white balance should be possible using the same method you used for automatic exposure. But instead of luminance you need to scan rgb. These can be used in a grade node in the white balance, and if you use a shuffle node, you can combine the luminance of the old backplate with the hue and saturation of the graded clip. Convert the hsl back to a linear. You should get a white-balanced video that retains the original brightness. The video that you use for scanning might need some adjustments beforehand like using a key and premulting it so that only the bright areas affect the white balance.

OMG THANK YOU! I've been trying to understand colorspaces and gammas and what-not, but it's been confusing lmao. I've been dirty compositing all my life and never messed with setting my color inputs and outputs but I will get better I promise! Thank you so much for the feedback, it genuinely means a lot! :)

[@hasselhoff3379]

@@curtskelton I’m still struggling with certain aspects but the basic idea is that you have your linear file that you carry from program to program to retain as much information as possible (think of it as the “raw” file). The linear file is great for the programs to do calculations with but it doesn’t look right so you have a viewport transformation (think of it as a lut). Internally blender, nuke, Houdini etc uses linear but they have a view transform like aces or agx to convert the “raw” file in to what looks correct to us. That transformation gets applied when you for example save a png in sRGB inside of blender or export a sRGB mp4 out of nuke. If the view transform is different from program to program the image looks different as well. In nuke you can use a custom ocio config and select the one you can find in the install location of blender. I think it’s under the data, Color management folder. It works if it’s a full cg composite but the default aces config that comes with nuke has all the transformations that you might need that convert x footage in to linear. So if you can use agx as it’s technically the best (compared to aces and filmic). The only thing you might have to do is to color correct agx after the transformation gets applied as it tends to look a bit flat. input transformation are there to convert whatever you give the program to linear so nuke can do it’s calculations. Output is the inverse of that. Linear to x.

[@curtskelton]

@@hasselhoff3379 You are legit the best, THANK YOU SO MUCH!

[@Venous_fx]

@@curtskelton yeah i was going to mention this. The first thing i noticed were that the rolloff in the highlights were too harsh and the highlights too saturated. You tried to correct this but it just looks off. AGX automatically handles the tonemapping in a very realistic way. From here you could degreade to more closely match phone footage as he said.

[@hamedbadiee5314]

I tried to use aces workflow but i got a problem. When i export as exr (both linear rec.709 and ACEScg color space )and i try to convert it back to srgb or 709 in nuke its darker and its not just a gama problem ( i tried using grade node ) How can i match color from exr ACEScg to the blender viewport render ( also png export ) ? I tried using custom ocio from blender directory and checked if it works and works absolutely perfect. Ps. I used srgb standard, flimic , standard and still no good. So if i wanna use acec1.2 in nuke and i wanna use my render exr ACEScg, what is the correct way to match the color?

Love it! At around 45:00 I was like yeah, but I'd blur it just a bit so it's not so perfect... then you said "iPhone doesn't have a f-ing matte of the sky" and you blurred it. Love the fact when you learn imperfections make perfect, that you start destroying the image a bit and it's more realistic.

[@jackrasksilver6188]

27:15 In the equation you present, exponent(3) simply returns 2 (This is the exponent of 3 in the IEEE 754 floating point representation). So, this means you are just multiplying by 2 here (Notice the result change from -0.434379 to -0.868758). Thus, your equation is still linear. Here is an equation that may work better. First, set the exposure setting "Adjust in" to "Density." Then set the equation to log10(targetLuminance/averageLuminance). This is an example of how it should look in Nuke: log10(0.45/parent.CurveTool1.intensitydata.b) You can multiply the whole equation above by a number [0.0 to 1.0] to lower the intensity of the effect.

[@ansems3309]

I watched this yesterday up until around 30:00. Then saw the tab half an hour ago and was like "Oh yeah! That was interesting! Lets finish it!" I think it took me around 15 minutes to notice, that this isn't a Nuke Tutorial on how to edit a video clip. At one point I even thought "If you want this to look like an iPhone video, then take the video on an iPhone..." until I saw the "CGI" part in the title! xD

Dude this is great. I have struggled with creating 3D environments for my renders but I'm soooo sick of just relying on an HDRI because they're so flat and lifeless.

[@jaym2267]

Idk if fortunately or unfortunately I'm in the middle of the compositing spectrum, I use Davinci Fusion for compositing. I really enjoy using fusion for compositing, but even I notice its own shortcomings. It did get my brain to wrap itself around the node-based workflow for compositing and more basic/intermediate compositing language, so Nuke doesn't seem super daunting anymore compared to how I thought of it whenever I was using only After Effects. I still stick to Fusion mainly because of the 500$ annual price on Nuke, but whenever I think its time I'll switch to Nuke. Even the creative cloud nowadays goes for like 600$ so nuke seems more like a steal than AE does xd

[@rano12321]

Fusion is amazing, anything node based is magnitude better than layer based AE.

The only one hour tutorial that i could watch was this one

[@davidramis-us]

Incredible! Ive been working on this same idea! Its really interesting that you are not using any noise.. Are you trying to achieve the noise through the hue and saturation changes? Specifically I have not found a defualt option on any software that emulates digital noise (NOT grain). This ties into how CMOS sensors capture color data. Each pixel only captures green, red, or blue, not all three, and interpolates between them. And then there is a general noise in the data for each pixel with its intensity dependent on how much light hits each sensor, which is why darker areas have more noise ( in both renderings and photographs, but differing in effect). This was so exciting to watch and would like to talk with you a bit more about it!

[@SianaGearz]

"iphone have no motion blur" of course when you're outdoors in daylight the effective shutter speed is very high. Of course there is no real shutter but there's electronic shutter by unearthing the sensor lines. Also mobile cameras do have rolling shutter, of course whether you want to simulate it or not is up to you, it might not be that important. Also Blender compositor consider despeckle -> kuwahara -> bilateral blur, then maybe blur and sharpen with different kernels with blur being wider and sharpen narrower to create just a little bit of sharpening ripple without actually increasing sharpness.

[@MireiaMontoroFerrandis]

[@Ebowleslap]

Not to be rude but I just tested on my iPhone and there is motion blur- the difference is that you took a PICTURE not a video to check the blur. with pictures the shutter speed and whatnot is different. With videos you do get motion blur on iPhone, even with just a hand wave. Love you bro

[@curtskelton]

I cut out a 5 minute chunk where I talked more in depth on motion blur when I really should have kept it in lol. I basically say to do exactly what you just did, which is get your own reference video. I filmed so many cars on the highway during peak sunlight and there was not a single pixel of motion blur with my camera (iPhone 11). HOWEVER, (and I really regret cutting this out now), there is motion blur when you film inside, in shadow, or at different times of day. And if I could do this video over again, I would've even keyframed my motion blur to go up just a tad, as I enter shadow. Ily2bro :)

[@Ebowleslap]

@@curtskelton that’s fair- I also feel like motion blur like you said is a lot about point of reference, so maybe you would have some blur on things that are moving fast in relation to you but not much on like the actual car- so if for example you drive past that car one lane over to you it would have some blur especially on the tires, whereas stuff far away isn’t going to be very blurry because it’s just not moving that quickly across the screen

[@Ebowleslap]

@@curtskelton you also did technically turn it on a bit so you did the right thing- the wrong choice would’ve been no blur

[@enriquebaeza9949]

Great video 😍😍thanks

[@MissMoffet19]

The motion blur is an effect of a slow shutter speed. Since iphones have a fixed aperture the only way to lower the exposure in a broad daylight is to max out the shutter speed which is a no no in filmmaking and filming overall. This is why this man is right and why iphone footage can look jerky especially in well lit scenes.

[@MissMoffet19]

High shutter speed is used consciously for artistic effect or in action scenes so the moves of the actors are not blurred.

Hey bro love this video it's awesome! I use AE and really considering switching to Nuke I had a question when you mentioned how non-destructive Nuke was when scaling and rotating footage. I feel like I'm missing something because in AE I don't lose any information when using the transform controls to scale or rotate a footage layer?

[@curtskelton]

@@williamgaither6351 Hey thanks for watching the video! When you typically scale down a video and then scale it back in AE, you’re not gonna lose any quality, don’t worry lol. I was referring to a different video I made a while back where I actually WANTED the quality to decrease so I scaled down my footage in AE, precomped it, and then scaled that comp up. And the quality was terrible. I should’ve explained that a little bit better my bad lol.

[@TR-707]

pspspspspsps - motionblur depends on shutters speed which depends on amoutn of light in scene (time of day, dark basement etc)

[@aonozan]

1:58 Reason why it does not work there is that its not a float field so your calculation does not get you float. If you did whole calculation in one equation(100/24*30) you would get exactly what you need. This is how it has to work because you can not have float number where you want integer number.
