Uh hello guys, welcome to this video. So
0:02
in this video, I'll show you I built out
0:04
a fmpg video editor directly in the
0:07
browser using NodeJS Express. And uh
0:09
this is the actual video editor. So here
0:12
you simply select whatever video file
0:14
that you want to edit and you can
0:16
directly edit this. Simply select the
0:18
video and drag the video on the timeline
0:20
section and you can play the video as
0:22
you can see in the video player. And
0:25
then we have a bunch of options. You can
0:26
trim split the video. So if you want to
0:29
trim the video, you basically right
0:31
click and it comes with all these
0:33
sliders out there. So it makes it easy
0:36
for you to trim the necessary part of
0:38
the video. So it's entirely built inside
0:41
HTML, NodeJS and Express. So this is the
0:44
full directory structure. All the source
0:46
code files are fully customizable. So
0:49
you can directly purchase the full
0:50
source code. The link is given in the
0:52
description. And if I show you the
0:54
package.json JSON file. It's entirely
0:56
built inside NodeJSON Express and all
0:59
the code is fully customizable. This
1:01
these are all the FMPPG web assembly
1:04
libraries.
1:05
So the link is given uh after you
1:08
purchase it, you will get the source
1:09
code from Google Drive. And this is the
1:11
JavaScript code here fully customizable.
1:15
And here you actually use these sliders
1:18
here to actually trim out the necessary
1:20
portion.
1:22
And after you are done, you simply click
1:24
the done button and then you click the
1:27
render button to actually start the
1:29
processing. Uh so once you click this
1:31
button, the FMPG processing will start
1:34
and after that you will see the download
1:36
button and you simply click the download
1:38
button to actually download the output
1:41
video file. So it's a fullyfledged uh
1:44
video editor project which is there. It
1:48
will save you a lot of time because it
1:50
directly executes it in the browser. So
1:53
we are running this application locally.
1:55
So it's also very easy for you to deploy
1:57
this as well.
2:00
So the link is given in the description
2:02
guys. You can directly purchase this
2:04
project and it's a single page
2:06
application. You can even change the
2:08
quality of the video as well. So here
2:10
from the drop-down you can select
2:12
whatever dimensions here and you can
2:14
change the quality of the video as well.
2:17
And also you can split the video into
2:19
multiple sections. So you right click,
2:21
simply split the video. So just select
2:24
the mouse at this location. Just click
2:26
right click split. And here you can
2:29
split a long video into multiple parts.
2:31
So it's really easy. You can do the
2:34
splitting trimming of the video. So it's
2:37
a timeline based editor. So if you're
2:39
