uh hello guys uh welcome to this uh live
0:05
stream so in this live stream I will
0:08
show you
0:10
a ffmppg web assembly uh video trimmer
0:13
or cutter application that I developed
0:15
inside the browser it directly runs in
0:18
the browser which is used to trim your
0:21
videos or cut your videos using a
0:23
timeline video editor this is the
0:25
interface which looks like this you will
0:28
choose your video file it can be MP4 it
0:31
can be any sort of file
0:36
so
0:40
let me just select any file here as you
0:44
select your video you will it will
0:46
automatically construct the timeline
0:48
that you see right here at the bottom
0:50
side and using this timeline it becomes
0:53
easy to trim out unnecessary parts that
0:56
you don't want so you can see how easy
0:59
it is so as you basically move the
1:01
timeline it will show you the starting
1:03
duration to the ending duration
1:06
so 3 seconds you want to trim out you
1:08
can even trim preview the trim as well
1:14
and then there is a button here of trim
1:16
and download so as you do the trim your
1:19
trimming will be complete the cutting of
1:21
the video is complete
1:24
so this is your trimmed video
1:29
so it is also deployed on my website as
1:32
well you can try out this tool so it's
1:36
called as uh video trimmer editor tool
1:40
so the latest tool that I deployed so
1:42
you'll basically choose the file
1:51
so you choose your file here it will
1:53
construct the timeline and then using
1:55
this timeline you basically trim out the
1:58
specific portion so if you need the full
2:00
source code of this application the link
2:02

2:32
you also have the download button as
2:34
well so you can download this trimmed
2:36
video directly inside your machine so
2:38
you don't require any editor you can do
2:41
this process entirely in the browser
2:43
itself select the location there this
2:45
will save you a lot of time as well so
2:47
the source code is very simple guys
2:50
after you purchase it you will
2:51
automatically be redirected to Google
2:53
Drive where you will get this zip file
2:55
so all the pre compiled binaries of
2:58
FFMPJ have compiled this and store it
3:00
inside this folder so this will make the
3:03
job very much easy for you and this
3:05
index html file which will contain the
3:07
all the source code of this trimmer
3:10
it's almost around 492 lines of code
3:14
so this is all the source code you will
3:16
get
3:18
so it will be easy for you to modify the
3:19
source code as well if you know some
3:22
kind of coding as well you can do this
3:25
and uh
3:27
can easily modify this as well easily to
3:31
deploy this as well because it's a
3:32
single file index html so it's a
3:35
complete editor
3:37
you can even run this locally as well so
3:40
if I run this locally now we are running
3:42
it on local host as you can see you
