Uh hello guys in this video I'll show
0:04
you if you are tired of using desktop
0:07
video editing software you can replace
0:09
desktop applications of video editing
0:12
directly using this editor that I
0:14
developed entirely in browser using
0:16
nextjs it has all the features of a
0:19
typical video editor you can edit your
0:21
videos add text images and it's
0:23
developed in nextjs which is a great
0:25
framework of react and it's using ffmpg
0:29
web assembly library. So you can see
0:31
it's a fully fleshed editor. We have
0:32
added text, images, everything. We can
0:35
change the resolution, quality and then
0:37
it comes with this progress bar. So it
0:39
will actually process your video frame
0:41
by frame and once it completes, you will
0:43
see the output video. This is actually
0:45
the overall project. It's coded inside
0:47
Typescript. Each and every file is
0:49
customizable. You can change the source
0:52
code and add additional features as
0:53
well. The link is given in the
0:55
description. you can directly purchase
0:57
it and it's using ffmpg web assembly
0:59
library and it's also using the nextjs
1:02
latest version and react as well and we
1:05
are running this project locally as you
1:07
can just see right here at uh localhost
1:10
4000.
1:13
So we started this as you can see
1:15
localhost 4,000
1:17
and it is rendering your videos frame by
1:19
frame. Uh so once it completes the
1:23
processing you will see the output
1:25
video. So you can just see here
1:28
it's actually processing frame by frame.
1:32
So it's actually a fullyfledged timeline
1:34
based editor. It doesn't have a back
1:37
end. It basically works in the front end
1:39
only and it's using nextjs
1:42
and ffmpg web assembly library.
1:46
So you can easily deploy this if you
1:49
purchase a domain name or if you need
1:51
the source code how I built it from
1:53
scratch the link is given you can
1:55
directly purchase it. So you basically
1:57
see this output video now the text image
1:59
everything is added and you also see the
2:01
download button and if you want to see
2:04
the actual full demo of this you again
2:07
basically
2:10
if you want to create a new project you
2:13
go to the project section and here you
2:15
create a new project right here and you
2:18
will be redirected to this timeline
2:20
based editor. So here you actually first
2:22
of all select your video add this to the
2:25
timeline section. So whatever is the
2:28
desktop software that you're using it
2:30
will save you a lot of time because you
2:32
no longer need to open desktop
2:35
applications.
2:37
Now if you want to cut you basically
2:40
select the video and it will split this
2:42
video into two parts. So the first 5
2:44
seconds if you don't need this part you
2:47
can delete this. And now if you see the
2:49
length becomes only 6 seconds. Uh you
2:53
can change the volume of the video, you
2:54
can change the XY position, the width of
2:57
the video, everything is customizable.
3:00
So you can just see here and then you
3:03
can add the text here.
3:05
Can just see how easy it is.
3:09
And here you can change the color of the
3:11
text.
3:14
You can add the text as an overlay. And
3:17
then same goes with image as well. So
3:19
here you can even select your own audio
3:22
file as well. You can replace the
3:23
original audio. So this is for video,
3:26
this is for audio image and this is for
3:29
text. So it's a fullyfledged. You can
3:32
now add the image to the timeline. Again
3:34
you can split the unnecessary part.
3:36
Delete this.
3:39
And here you can control the width and
3:41
the height of the image. So you can just
3:43
see here how easy it is to edit your
3:46
videos directly in the browser. You can
3:48
even
3:49
it will do the basic video editing for
3:51
you which is required for adding text
3:53
image changing the sound of the video
3:56
and this will output video will look
3:57
like and then you have the export option
4:00
you can change the resolution quality
4:02
everything. So this is actually a great
4:05
alternative or replacement for your
4:08
desktop applications that you are using.
4:11
So it's actually a web application
4:13
directly executes it in the browser. So
4:16

4:17

4:20

4:22
