Nuke: Additive Keying without Green Screen I extracting finer details by divide & multiply
HTML-код
- Опубликовано: 22 апр 2024
- Unlike traditional keying methods that use an alpha channel to control the transparency of an image, additive keying works by adding the color information from the source layer to the destination layer. This can help to preserve fine details, such as hair or smoke, that might be lost when using an alpha process.

Very simple and concise explanation. Thank you!
Thank you 🙏
thanks a lot
Absolutely brilliant, this tutorial showcases a fascinating approach to additive keying, The divide and multiply technique truly unveils a whole new level of precision and creativity in post-production. Thanks for sharing this insightful and innovative method.
😇✌💫🍻
Thank you so much for explaining this! Best video I've seen on this topic :)
glad its helpful. ✌
Such a nice explanation so good ❤
glad, its helpful. Thanks
Awesome ❤
jai ho ✌
Do you have a video where you finish the refinement to the end showing the nodes clearly? I'm following this method but get stuck at the keymix and the premultiplying section. That would be very helpful.
Hi sitinprettyProductions ruclips.net/video/G1ct3bqijJo/видео.html please check this, is it helpful ?
Brilliant, but How you manage the dark areas on the butterflies, because when you multiply you are multiplying also the values on the butterflies, so there is a problem with blacks...
Hi Ilaria Baldini, its really apt question. in this video my primary target was to just talk about concept of divide & multiply, obviously refinement is next step. to your query my answer is "manipulating contrast ratio ( in this case its butterfly) always helpful but this should be done selectively (using masking)"
@@auxiliarynatter thanks!!🌟
@@auxiliarynatter I see! The visual explanation or the mathematical process it is totally worthy!!🌟
And also, in the first case , you are applying a saturation node with the value of 0, so you are removing rgb and not luma, but how you dial, after, with the restoring of the hair-details- colours?
Hi Ilaria Baldini, i missed to mention that adjust(lower) saturation as per need ( making zero is not rule) also in case of green screen or blue screen doing proper despill before divide operation to both plate & Clean Plate exactly the same way gives the proper intended color.
Thanks a lot to bringing this into attention. much appreciated. 🍻
Thank you
Genius
cheers 🍻
Bro oru doubt?,for tutorial don't explain how to do clean plate other then for script doing clean plate not mentioned in ur script bro,pls clarify this doubt
Hi Karthi Keyan, can you please rephrase your query, as i am not getting properly. Thanks
awesome as always. i used this method but i didn't understand why you cleaned hair with paint node why it is necessary in chroma and live action plate also?
hi Narutouzumaki ,i have not cleaned hair with paint node. i am not getting you ! can you suggest where ( time of video) you feel that i cleaned hair with paint or can you please rephrase your query. Thanks
Sure 7.52@@auxiliarynatter
@@Naruto_uzumaki7979 hi Narutouzumaki, i said "i made clean plate with plate information, i didn't do any cloning" means i have taken available information from different frame which area is free from hair and made a clean plate, i have not used any paint node in above showed both example.
even
i would like to highlight please make clean plate using available plate information .
i hope it's helpful. thanks
@@auxiliarynatter thanks sir really appreciate such in detail explanation 🙏
Ni
thanks
