Hello. First of all, thanks for your tutorials. They are easy to follow and very detailed. I'm currently working on an anamorphic shot that is quite long (798 frames). It is mostly a panning shot with little parallax and heavily distorted. I've done the undistort with a lens grid quite nicely, tracked various points over the entire shot but when I click "Calc All From Scratch" it gives me the following error: "No rootframes, in pgroup 'pgroup#1': No rootframes with sufficient number of common points could be found." Do you know what does this mean? Maybe I still have insufficient tracks? Thanks in advance!

No worries, glad they have been useful, This usually happens if you don’t have enough tracking points, you need a minimum of 6 tracking markers on every frame, You can open up “timeline” in your windows tab and that can indicate where you need more tracks Hope that helps

So what if you have footage and lens grid that have already been desqueezed and exported out with a 2:399 aspect ratio, what lens distortion model do you use, would you the 3de4 Anamorphic Standard Degree 4 without using the squeeze x and y ? Thanks, your tutorials are done very well and answered a lot of questions I had.

hi, thank you, Im happy they have been useful :) you would go through the exact same method, but keep the pixel aspect as 1, you will still need to use the anamorphic distortion model as there may still be some squeeze in there hope that helps?

if you already know the size of the sensor of the blackmagic 4k, how did you get the height of the sensor with the anamorphic adapter?

@VFXTutors 4 жыл бұрын

the sensor size never changes, its always the same, unless you film in a cropped format, i always film in the full resolution as its better to crop in post and not film in a cropped format. hope that helps?

@@VFXTutors oh ok, yws what I was talking about in the previous message is about using the 5d mark iii with magic lantern with crop(zoom) x5 at 3520x1320 resolution and aspect ratio of 2:70:1 or sth like that, right now I dont have my camera with me. In this configuration I have no idea what is the sensor size

@VFXTutors 4 жыл бұрын

i would always use your sensor size height as it is on your camera, then try to survey to your set geo, it will always work that way, but your field of view might be off. this might make things looks smaller or bigger, but i would just use your camera sensor height and leave width as passive. Track it and put a 3d model in the shot, check if it looks too big or too small in shot.

Thanks for the video @ 3:25 you mention that the lens is actually wider than a 50mm now. Why actually is it?

@VFXTutors 2 жыл бұрын

its how an anamorphic lens works, its not a spherical lens, more like an ellipse shape, so when you look at the raw footage it looks all squashed as its got a much wider field of view. then depending on the type of lens, mine is a X2 so i have to stretch the image 2 times wider to get the image looking correct. hope that helps?

Do you mind I request panning shot tutorial? I tried it, but couldn't even success it once..

sure i can try so sort something out, its hard to film stuff at the moment, but ill have a look in my video library :)

hello, remember the image I sent you ? would that be considered as Anamorphic?

@VFXTutors 4 жыл бұрын

hey, not really, what you did was effectively stitching multiple images using magic lantern? im not sure but anamorphic has a lot of different characteristics dues to the shape of the lens, they're mostly known for the lens flares.

@vfxschool1650 3 жыл бұрын

sir what is an anamorphic video

@VFXTutors 3 жыл бұрын

Hey, Anamorphic is a type of lens that allows you to capture very wide shots, the most common anamorphic lenses capture double the width by filming with a lens that squeezes the footage then you remove the squeeze in post
