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.
🚀 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.
💡 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.
🖥️ 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
