Q & A

ما هي الخطوة الأولى التي يجب إتباعها في المونتاج الثلاثي الأبعاد؟

الخطوة الأولى هي الانتقال إلى علامة التبويب لـ VFX وفتحه، ثم الانتقال إلى المجلد الذي يحتوي على اللقطات.

كيف يمكن تحسين عدد التتبعات في Blender؟

يمكن تحسين عدد التتبعات عن طريق زيادة قيمة الthree shold، ولكن يجب الحفاظ على قيمة منخفضة لتجنب حدوث مشاكل في المعالجة.

لماذا يجب حذف بعض التتبعات؟

يجب حذف التتبعات التي تظهر بشكل متقلب أو تتحرك بشكل غير مستقر لأنها قد تؤثر سلبًا على النتيجة النهائية.

ما هي الطريقة الصحيحة لتحديد الكاميرا في Blender؟

بعد إكمال التتبع، يجب تحديد الكاميرا من القائمة ثم الانتقال إلى إعدادات الكاميرا لجعل النهاية عالية لرؤية الأحداث بوضوح.

ما أهمية إعداد النطاق الFOV في Blender؟

الإعداد الصحيح للFOV (optics center) مهم لتحديد الكاميرا بشكل دقيق، مما يساعد على الحصول على حل إملائي صحيح.

لماذا يجب ضبط الحجم في Blender؟

ضبط الحجم يساعد على تطابق حجم النماذج ثلاثية الأبعاد مع حجم اللقطات الفعلية، مما يساهم في واقعية الرسم الثلاثي الأبعاد.

ما هي الخطوة التالية بعد إعداد التتبع؟

بعد إعداد التتبع، يجب ضبط الكاميرا وتعيين الأبعاد، ثم ضبط الألوان والضوء لجعل الرسم ثلاثي الأبعاد يبدو واقعيًا.

ما هي الطريقة لجعل العناصر تتفاعل مع السطح في Blender؟

لجعل العناصر تتفاعل مع السطح، يجب إضافة خاصية الجسم الصلب (rigid body) للعناصر وضبط الخصائص المناسبة للتفاعل.

لماذا يجب إعادة ترتيب العناصر بعد إضافتها إلى الكاميرا؟

إعادة ترتيب العناصر بعد إضافتها إلى الكاميرا لضمان تطابقها مع الوضع الطبيعي للعناصر في اللقطات.

ما هي الخطوات اللازمة لإعداد الضوء في scène الرسوم الثلاثية الأبعاد؟

لإعداد الضوء، يجب إضافة مصدر ضوء مثل الشمس، و調整 موضعه وقوة الضوء لتحقيق التأثير المطلوب.

ما هي الخطوات الأخيرة قبل التقديم في Blender؟

قبل التقديم، يجب ضبط الإعدادات النهائية للكاميرا والضوء، وإجراء التعديلات اللازمة للعناصر والألوان، ثم إجراء التقديم.

🎬 VFX Tracking and Camera Setup

This paragraph discusses the initial steps in a video project focusing on VFX. The speaker begins by opening the VFX tab and accessing the necessary footage, which they plan to share in the description. They then proceed to load the footage into Blender, using the footage's features to track and create a 3D scene. The process involves adjusting tracker settings, deleting problematic trackers, and solving camera motion to achieve a good tracking result. The speaker also sets up the tracking by selecting specific trackers and aligning the camera view to match the scene's perspective. They ensure the frame rate matches the footage and make adjustments to the scene's layout to fit the camera view.

05:01

🚀 Animating and Scaling Objects

The second paragraph delves into the animation process of a coffee bin in Blender. The speaker scales and saves the coffee bin, then imports additional 3D models, such as a coffee box, which they append to the scene. They remove any unnecessary rigid body settings and use the 'Copy Attributes' add-on to match the rotation and position of objects in the scene. The speaker then animates the coffee bin, spreads the beans, and adds rigid body physics to the bin and beans for a realistic interaction. They also adjust the friction settings for a more natural movement when the beans hit the ground.

10:02

💡 Lighting and Rendering Adjustments

In this section, the speaker focuses on setting up the lighting for the scene to enhance realism. They add a sunlight lamp, adjust its position to mimic the direction of the natural light, and tweak the Cycles render settings for better performance. The speaker also addresses the need to reposition objects like the coffee box and cup to improve the scene's realism. They mention the importance of patience when dealing with the physics simulation and provide tips on how to adjust the rigid body settings for a more accurate simulation. The paragraph concludes with a reminder to subscribe to the channel for more content.

15:03

🖥️ Finalizing the Animation and Compositing

The final paragraph covers the last stages of the animation process, including refining the scale of the beans for a better visual effect and adjusting the lighting to match the background. The speaker demonstrates how to simplify the compositing process in Blender to avoid rendering issues and improve efficiency. They render a sample image to showcase the final look of the animation and provide a brief overview of the changes made to the compositing nodes for a cleaner and faster render. The paragraph ends with a call to action for viewers to subscribe, like, and comment on the video for further queries.

Transcripts

hey guys in this video we're going to

have a look on how I met the animation

uh that I just shown you in the

beginning of the video so let's begin it

with VFX going to VFX Tab and hit open

and let me just go to the directory

where I have the footage I will put the

link all the necessary file in the

description down below you can check

them out if you are interested in the

same footage and same 3D models you can

also check them out okay so here's the

footage is loaded and now it's time to

drag it so click

prefetch and then click detect feature

so we have so many trackers and you can

increase the tracker by the three shold

value you

can you can decrease the three shold

value in order to get so many trackers

I'm going to go for not a very high

value because we will not be able to uh

solve problems

so I'm going to go for location and

rotation normalize and previous frame

and those are the basic settings you

have to do and they make the tracking

perfect okay so we got uh tracking done

as you can see some of them are going

well and straightforward but some of

them are just zigzag and moving up and

down so you can delete them from the

from the crew of editor and I'm going to

delete one of Select by select them by

clicking left click and X to delete them

I'm going to delete this one also this

one and also that one maybe this one and

now we have perfect trackers in the

scene that is what we want go to solve

click focal L Optical uh Center and

because we don't know the actual uh

values of it because I have downloaded

this footage from internet so I really

don't know how is the focal length so we

have to let the blender know how is it

so let's just click solve camera motion

and see what we get

so we got 0.35 which is a perfect uh

solve error and this is what we want now

it's time to set up uh the tracking so

I'm just going to select three of The

Trackers that one and that one and uh

click

floor okay so we got floor here select

the camera from here and go to camera

settings make the ending to something

like very high in order to see perfectly

okay so we now we now can see what is

going on in the scene I'm going to

select one of the tracker and hit set

origin and I'm going to go for x-axis

set x-axis and then set Y

axis oh I think it's been rotated very

badly but I think I'm going to select

this

one maybe that

one this one maybe yeah okay that's fine

that's fine and now it's time to set up

the

scale first I'm going to set as

background and I'm going to go to camera

settings I'm going to go to background

image and I'm going to increase the

opacity level to something like very

high and I'm going to hit setup tracking

scene now we have something like that

the cube is very small because we have

not seted up the scale yet I'm going to

select these two

trackers hit set scales it's very big

I'm going to go for four because the the

mod might be a 4 meter I think it's

measure I think yeah

set

scale but I think it's not perfect yet

we going to go for

seven set scale okay that's perfect hit

and go to view and go to camera to view

and then try to align it manually

because blender always not do it

perfectly so if you move the camera it

doesn't even matter for

blender okay so now let's see oh the

first thing we have forgot in the

beginning of the video is to have the

same frame rate as the footage have so

it's

29.97 and that's it let me just go to

layout by clicking General and going to

layout and go to camera

view okay so I think it's perfectly

stick to the ground and this is what we

want I'm going to delete the cube I'm

going to scale this on x-axis because

this is a shadow catcher and our scene

is a little bit huge because we have a

huge uh okay Nas Cafe and we have to add

it to there I'm going to move it into y-

axis we have a little camera here I'm

going to scale it I'm going to I'm going

to scale it okay we scaling anything up

we have two layers here we don't need

background layer so let's delet it and

also the background collection hit X and

delete it and now we just have a

foreground collection which removes the

which always remove all of the dots we

have I'm going to rotate it on z-axis

I'm going to go for local and I'm going

to scale it y like that go Y axis I'm

going to expand the timeline and let's

play yeah it's working perfect and this

is what we want I'm going to scale it

xaxis control s uh let's save it so I'm

going to name it something like a man

track

maybe hit enter and click show blender

file so now it's time to load other

files uh that we need so I'll put the

link to the same BL file that I used

for for the for the test or for all the

3D model you know so I'm just going to

import them okay so it's in object and

I'm going to go for coffee box these one

and these three objects click pend and

it will append them okay so I already

set it up rid body you will not have I

will remove them um I'm just going to

remove them so you will not get

confused okay so it's not perfectly

rotated or maybe we can TW it around so

I'm going to rotate it on x-axis make y

AIS no no in order to get a perfect

rotation as the plan have you need to

come to edit go to preferences go to

add-ons and search for

copy and here we have copy attributes

menu and this is very useful let me just

show you how to use it so in order to

have the same rotation and uh location

and scale as the plan have you need to

select first select the box then the

plan then hit contrl C you will get so

many option first you will have just

copy object but now we have so many

click copy rotation and you will have uh

the same rotation as the plan how so I'm

just going to go to material

View and as you can see I'm just going

to move this up

slightly like that and if I go to camera

view let me just rotate it on Z X is

like that hit contrl s and also these

cup object select the plan and hit

contrl C copy rotation and now we have

same rotation as the plan does have okay

so I'm just going to move it up I'm

going to rotate it on Z axis and

180° so we will have the text on the

camera

side okay so I'm just going to move it

uh let me just go to the global and I'm

going to move it on xaxis like that okay

okay okay it c contr s okay so now it's

time to animate this coffee bin and uh

it's very little let me just scale it

slightly up like that hit M and move it

to a new collection I'm going to name it

something like collection two and these

four objects into collection uh

foreground and now we have separate

objects I'm going to delete the light

because we don't need it right now okay

so this is something we all coffee bin

and now it's time to spread them

up I'm going to move it up I'm going to

hit shift d I'm going to rotated I'm

going to hit shift d shift d shift d

rotate them try to have a long distance

between them rotate them randomly

because they will not feel like they're

copied but just try to make it very

detailed and just select them again and

again and again rate and maybe we can

move them up like that R it like that

shift d move it to H rotate it select

all of them and move it and duplicate it

up like that rotate it and yeah this is

something we want I'm going to scale

this up a little bit because we want it

to be act as a a ground and it will

entact with those beans so we have to do

it SC it down okay so we have got one

thing which is adding rigid body into

bin I'm going to hit a rigid body and

add some of the rigid

body okay so it type is active and uh

this must to be increased a little bit

and H surface response is going to be a

little bit bony because we want it to be

like a ball and they just not stick into

the ground they move up and down when

they hit the ground and I'm going to

select all of the

objects and as you can see the man

object is active and come to object uh

rigid body and active now we have active

everywhere control

Z this object because we want to have

the same setting for all of them to

select this object uh right click and oh

let me just select all of them select

object okay so right click and copy to

select it so the same setting will be to

all of them and also do it for Bon sness

as well copy to selected okay so we have

uh we have a rigid body on the beins now

it's time to add it to the cup and the

box I'm going to select them and hit

rigid body it's bive and just left all

of the things at default but one thing

to change its shape because it's a mesh

I'm going to select the box I'm going to

click rigid body it's an piece of rigid

body it's just a mesh you can call it

select the plan cck a rigid body it's

not active it's paive it's not convex

Hall it's just yeah lift it

that okay so select the box I think I

need to increase the friction slightly

because you want some of the particles

to stuck on the top of the box and also

the cup I'm going to increase the

friction for the cup and hit control s

in order to Pat our

back the rigid body we have setting in

the scenes rdid body expand it and come

to Kish and click back it might take

while because it depends on the objects

you have in the scene that interacts

with each other but it happens when the

interaction does happen as you can see

it's doing it faster and if the scene is

very heavy it can take some time so be

patient with it and it's going to happen

very fast so let's wait for

this and see what we get H okay by the

way consider to subscribe to the channel

because it helps uh me to be motivated

and to

work and now if you play

it as you can see we can have some beans

falling into the ground and in order to

get a

bouncy hitting you need to delete this

back and go again to the physics select

the plan increas the bounc iness value

slightly and hit contr s and again go to

scene and click back so I'm going to

pause the video right

now okay so it's back again if you play

it we didn't got a very bouncy look but

uh it does look good and I think it's

perfect now it's time to set up some

lights because if lights is not perfect

it's not going to look realistic so in

order to get a light I'm going to add a

sunlight got I not use we're not going

to use any sdri or something because uh

sunlight works for me so I hope you got

me and I'm going to rotate it on that

axis because I have noticed that the sun

is coming from that way and I'm going to

go to camera view hit control

s I'm going to move it like that okay so

control s save it because blender might

get crashed change it the Cycles make it

a GPU compute turn on D noise for now

and

uh what we can change yeah we can come

to film and make it transparent that's

it Chas and let's see what we

get okay okay okay so first thing that

we missed up is the box is very uh is is

on a bad place because here's the the

human moves and I think it's not a

perfect location we can change it later

on and reback the simulation I'm going

to increase

the amount of sunlight and I think it's

perfect uh I think I have to move um the

box and the cup for now because they're

not perfect I'm going to move it

up I'm going to turn it off and see

okay okay okay okay going turn it on I'm

going to move it

on xaxis y AIS like

that going to scale it

down I'm going to move it

down something like this and I think

it's look good and slightly move it to

here and I'm going to move these two

here

slightly and I think it's perfect uh we

have changed uh some settings so we have

to change uh the rdid body simulation as

well and yeah I'm going to select all of

those objects I'm going to select

objects okay first we're going to come

to the rigid body settings delete the

back and I think we have to oh I think

the sun is in the collection of rigid

body I'm going to hit M and and move it

to a foreground then I'm going to

reselect all of those objects I'm going

to change it to Global and I'm going to

move it to Y axis like that

okay hit control s and now it's time to

uh maybe I can increase the bones in

this value I'm going to go select one of

the object and I'm going to increase the

bone this value slightly control s and

select other

objects and copy to selected and now

it's time to pick again control s back

it I'm going to pause the video so the

back is done if you play it we can

see we have got

uh we go back if you're not happy with

the scale you can scale those beans down

because I think they are very big but

for my final render I have rendered it

before that and they were small and you

can just go for it that's it and

lighting is looking good it's just same

as the background and I think we not

supposed to change anything else uh the

beans are likely to be very big so I

will show you how to make them smaller

because I think this will be a good

option I'm going to select all of the

objects I'm going to delete the back and

I'm going to change it to individual

Origins I'm going to I changed the

transfer PR point to individual origin

and they are pretty big I'm going to

scale them down C that and hit contrl s

and reback them okay so it's backing

again I'm going to pose it so it's back

again I'm going to play it okay I'm I'm

going to play

it yeah they're looking good loved it

you can now hit render no before

rendering it it's time to set some

compositing because blender default

compositing system is very complex for

blender to handle it can take some time

to render them out so in order to get uh

an accurate render you can twg it okay

so I will render one image oh I think I

have not changed the samples I'm going

to change it to 100 for now you can go

for crazy number but for now I'm going

to set it to 100 to render it faster to

show you how things

work I'm going to render

it and let's see what we

get so it's rendering I'm going to pause

it so as you can see it's rendered out

but the main problem is it seconding

time because blender have added some

default noes into

compositing and this is where the

problems occur I will show you simple

way of doing it going to delete all of

this

sheet

everything okay I'm not going to delete

the mov I'm going to delete those in

between so this is the mov C clip this

is composite node this is Viv node I'm

going to add a render layer

node I'm going to add an alpha over

node to here and then I'm going to

connect these image to the top socket

and this image to the bottom

socket I'm going to collect this image

to the viewer also and also to the

composite and that's it this is very

simple if you zoom in we got the same

perfect result and yeah that's done so

now you can hit the final animation uh
