VFX Bites: Lens Distortion Workflow Part 1
Вставка
- Опубліковано 18 тра 2019
- Hey folks, here is Part 1 of my new VFX Bites series: Lens Distortion Workflow, below are the attached files. This introduced the NEW lens distortion node updated since Nuke 11 and goes into detail the process of overscan within Nuke. Part 2 and Part 3 are coming with proper overscan/reformat pipelines for Maya and Houdini rendering.
If you'd like to download the nuke files/video content please check out my patreon tier for VFX Bites:

Excellent!!! I'm learning a lot.
This information is just pure gold! Thank you for this!
Instablaster.
wow awesome! very in-depth and very useful as i see that a lot of people miss the point, undistort and redistort footage and loosing a lot of quality.
Good Stuff..
you are the best teacher ever, even in udemy it doesn't explain like that
Hugo rocks sir ;)
You are a saviour, great informationd and tips that you share, blessings bro
There’s only one Savior and His name is Jesus Christ :)
hello ,hello . thank you ,i m always waiting for your new videos
Sim Alex hello :)
When calculating the maya render size for the undistorted plate you forgot to include the negative offset values in the lower left. Remember Nukes resolution starts at 0,0 in the lower left and goes to the upper right. so if you have a width of -140, -140 by 2188, 1220 Your render res is in fact 2329 x 1361
Daniel Smith yes sir, I address that in part 2 :)
How many feets far i must stand this grid on my camera ?
The frame must be full
Great series! Question, When tracking if you are using a Speed Booster(example: MetaBones Ultra .71x) , would you still enter in the physical focal length and film back size? Or would you have to do some calculations?
mgbigair the sensor size is what dictates that. So lens data entered always stays same. The sensor size is what is increasing.
@@VFXforfilm Interesting. What would the math be to determine your new sensor size for tracking in nuke?
mgbigair Well with the Blackmagic Pocket 4K its 18.75mm X 10mm. That’s for DCI 4K. The UHD sensor area is less on the horizontal (crops the edges).
@@VFXforfilm The "virtual" sensor size decreases? The physical sensor size is 18.96mm x 10mm. Wouldn't the "virtual" sensor size increase when using a Speed Booster?
mgbigair That’s the tricky part. I’d experiment by adding a .7 increase in size of sensor. Or other way by just dialing in the adjusted mm lens of cam.
Thanx from russian community!
I’m half polish/Russian. 👍😉
so STMAP is a map for my lens distortion and i can save this for another projects without this grid ?
Is there another way to determine how many pixels you require for overscan? I am using Nuke 12 and my settings seem to be different to yours, as I do not have the "add pixels" slider
Not sure, it’s been a while and am pretty busy with freelance to look into it right now, sorry.
do a smart vector demistified
Unfortunately I’m getting my masters at a very tough university. I’m barely finding time to do anything.
@@VFXforfilm oh no,
Hey. Can you please tell me " How to render out checker board undistorted image with overscan?"
Watch the video.
@@VFXforfilm I've watched but you haven't mentioned how to do this. Request you to review my question
@@firefoxbrowseraccount5709 I made a part 2
@@VFXforfilm Hii. Can you please reply back with link of that vid?
@@firefoxbrowseraccount5709 how hard is it to look up the same title with just PART 2 changed? Honestly, you are all take and no give.
