hey everyone welcome to another quick
0:02
filter grade tutorial if you end up
0:03
finding this one helpful please like and
0:07
today we'll be changing the aspect ratio
0:09
of a project in premiere pro it's
0:11
actually super easy and you might need
0:13
to do it if you decide to convert a
0:14
video to vertical to make it mobile
0:16
optimize or if you want to use a more
0:18
cinematic aspect ratio without
0:19
artificially adding in black bars there
0:22
are many reasons you may want to do this
0:24
so while the sequence you want to adjust
0:26
is open click on sequence from the top
0:28
bar of premiere pro and click sequence
0:32
here you can change most overall
0:33
settings about the project attributes
0:35
like frame rate resolution and audio
0:37
sample rate to name a few
0:39
to change the aspect ratio just change
0:41
the resolution numbers they are not
0:43
locked to a certain aspect ratio so you
0:45
can easily change these values
0:48
for example if you wanted to convert a
0:50
normal 1080p video just swap the 1920
0:53
and 1080 values now you'll have a 9 by
0:55
16 aspect ratio instead of 16 by 9.
0:59
premiere pro shows you the aspect ratio
1:01
next to the resolution so you can see
1:03
whether it's 16 9 or 64 27 which is near
1:06
21.9 for example if you wanted a
1:09
widescreen cinematic frame the important
1:12
thing to remember when changing aspect
1:13
ratios is that any footage that you have
1:15
on your project already will need to be
1:17
scaled again existing video assets will
1:20
remain at whatever resolution they were
1:22
before the change this means that
1:23
converting a horizontal video to
1:25
vertical will result in an image that
1:27
extends beyond the sides of the screen
1:29
rather than an image that fits perfectly
1:31
to the edges like before however there
1:33
is another option that may maintain the
1:35
framing of your clips a little bit
1:37
this tool is called auto reframe
1:40
right click on your sequence in the
1:42
project panel and select auto reframe
1:44
sequence you'll be able to choose from
1:46
some preset aspect ratios or make a new
1:50
then premiere pro will do its best to
1:52
convert the sequence it creates a
1:54
duplicate so if it isn't what you wanted
1:55
you'll still be able to go back to your
1:57
original sequence easily here's one last
1:59
trick for determining resolutions if you
2:01
know an aspect ratio you want but not
2:03
the resolution that you need
2:05
divide the aspect ratio like 16 divided
2:08
by 9 then multiply that number by your
2:10
vertical resolution to get your
2:12
horizontal resolution
2:14
so 16 divided by 9 multiplied by 1080 is
2:17
1920 thus getting your normal 1920 by
2:20
1080 resolution if you drop footage into
2:23
an empty sequence and the aspect ratio
2:25
settings as well as other settings don't
2:27
match you will be prompted with a
2:28
message asking if you want to change the
2:30
sequence settings this can also be an
2:33
easy way to change the settings if you
2:34
don't want to deal with all the math
2:36
if you drop in footage that is smaller
2:38
than the sequence size it will show up
2:40
as smaller to quickly change this you
2:42
can right-click on the footage in your
2:43
timeline and click scale to frame size
2:46
you can also manually adjust the scale
2:48
in the effects control panel
2:50
and that's all about changing aspect
2:52
ratio in premiere pro leave any other
