hey welcome to green-light today is the third and final video of the essential series and
we're talking about what is bitrate using the examples of the red dragon 6k and the Blackmagic
pocket Cinema Camera 6k first let's get into what is bitrate resolution and bitrate are different
higher the bit rate the better the quality which is not in resolution bitrate effects quality and
file size it really does a lot so bitrate is basically the amount of data used to encode
video or audio every single second so with that being said it will take up a lot a lot of file
sizes and a lot of memory on your computer so basically so when it comes to resolution
the higher the resolution / frame rates you must pump up the bitrate so it's not compressed poorly
so anything with a high bit rate you must compress it so either one of these cameras you must be able
to compress it correctly most websites and with their costs would just end up going really high
up if you have like a really big file size with a high bitrate video in there so basically it does
take up a lot from your computer it takes up a lot in um you know on the internet and even when you
put it in YouTube YouTube tends to compress all these files but keep the quality they're the only
ones that tend to do that obviously they're owned by Google so they have the money to be able to do
that but programs like Premiere Pro and DaVinci Resolve can compress your videos and be able to
use both of these with no problem now trying to use black magic in Premiere Pro is gonna take a
third party program which I believe you have to pay for I'm not sure of any that are free
out there yet but I haven't looked into it I'll look into it eventually um hopefully sooner than
later and I will let you know about that when I talk about the black magic let's say I do rent
it out or something like that so I do plan on doing that in the future myself um I love the
way it looks in comparison to the red dragon or any other red product but the red sensor size is
way way bigger the red sensor size doesn't have a major I mean the crop factor isn't all that
much they have a crop factor of 1.25 and I believe black magic has a 1.5 eight times crop and that's
not even including you know canon lenses and all that that the black magic could be able to use so
it all depends on your lenses too as well but for such a small pocket Cinema Camera this is
very very well built and very strong and as far as like bitrate and the encoding decoding is very
very good it shoots in pro res of four to two as well as black magics raw and all that obviously
may need be coated on a on a third-party program for Premiere Pro but when you do buy and purchase
the Blackmagic Cinema Camera you do obtain a free copy of DaVinci Resolve where right now
that is the best one of the best colour correcting programs out there so alone it's one of the best
colour correcting programs out there for feature films music videos anything you you may need
for it so for you to understand a little bit more about bitrate there's a couple things that people
talk a lot about CBR UBR and then passes just so you know a little bit of what they are CBR
is constant bitrate UBR is variable bitrate and passes is increasing number of passes so where
you can change your bitrate is basically in any of these editors so in video editing programs such
as Premiere Pro and/or DaVinci Resolve you can encode your own films and music videos and make
sure that the bitrate is at C be our constant bitrate is always good it stays consistent the
variable bitrate you might want to open that up for specific shots if anything like that
but variable bitrate is more of four shots with a lot of activity like trees and stuff like that if
you're getting a lot of like leaves and and very fine detail in your 4k + or 6k passes is pretty
good - it's the amount of time that your render is basically it's gonna go through your bitrate
and basically render out your project a bunch of times and then give you the best quality variable
bitrate allows your computer and your render to basically the computer will start deciding
whether or not it needs to have more of a bit rate or not in certain shots you need it like I
said already and that's very good to have but if you use passes passes the number amount of times
that you export your film and render it actually the number that you render your your project file
the program starts to know what's the best for each shot so each shot will have a different bit
rate but basically the number of passes that you do the computer becomes smarter and understands
your footage better and what you have on your footage so that's very good to have when you
want your highest quality uploaded on YouTube and or Vimeo or any other Avenue YouTube encodes for
you as long as you upload your highest quality video then you're good when you upload there's
different bit rates that you can look out for things like megabits per second and kill the
kilobits per second or something that you may have seen a lot on blu-ray discs and DVDs but
a lot of like 4k the average bitrate normally even for like a 1080p type file is like 8/8 bitrate is
average anything lower than that the quality is gonna deplete so if you have an 8 bit rate file
and you're shooting at 30 frames if you did the same thing and had an 8 bit file but then had an
shot at 60 frames it's gonna try and compress the 60 frames into the 8 bit so you're not gonna get
the full quality of that 60 frames you might have to bring up your your average bitrate and help to
you know depending on what you know resolution obviously and this is all dealing with 1080p so
you probably go up to 10 or 15 it depends on the footage that you shoot and what resolution you
shoot at from 4k the average is just 20 bitrate and DVDs are usually four to eight megabytes per
second so you know with that being said yeah that's definitely gonna be in that realm of
480p and stuff like that the average bitrate is 8 megabytes per second and DVDs are usually four to
eight megabytes per second so basically that's the amount of like the resolution for each pixel that
you're seeing just lossless video like going through on the DVD but going into blu-rays for
1080p and high-definition that you'll be seeing usually around 24 to 40 megabits per second but
when it comes to resolution they're not one in the same you gotta kind of balance them out so that's
what on a blu-ray that's what you would find including the 4k videos I believe like the 4k
movies are the same because for K's they're like 20 bitrate and that's what our YouTube handles
and those file sizes are gonna be good quality especially on YouTube if you upload them up on
YouTube they're gonna be compressed in their own way so they want you to upload a high file
size it's all up to your computer and how many exports you can do of your video and/or film
or the renders you're gonna do it all depends on how much space you have on your computer thank you
for joining me today on the third video of this essential series I really appreciate you taking
your time checking out these videos and if you like them please comment down below don't forget
to hit the like button and the notification bell I'm Giovanni samples and hope to see you here soon
we have more filmmaking videos coming out as well as blu-ray released videos every week and I've got
a number of mini blender tutorials just for you there beginner tutorials so you can learn a new
program and/or video editing program because it does a bunch of things all encompassing in one
program and it's free adidas as well as Ubisoft which is a gaming company has all sponsored that
program and their self financing it every month so every month they're almost hitting their quota
of a hundred grand a month so and they're making great strides there at blender 2.80 right now but
then there's blender 2.82 which is what they're planning to be their next release it's at alpha
right now so it's at a point where it's growing fast and they're working on this day in and day
out so thank you again don't forget to hit the like button and I'll see you here next
