Hello my viewers and channel followers.
Today I will show you how to reduce
video file size without losing video
quality. I will use peg to compress
videos for free and fast. FPEG is a free
tool and very popular. I have an
input.mpp4 file that is over 28 MB in
size. I will try to reduce this file
today and show you the final result.
This is a quick way to reduce the size
of a video file with a simple command.
Also, the process is much faster than
with other video tools I've worked with
before. First, I will need to open a
command prompt window through which I
will call the FPEG program specifying
the necessary command parameters.
Next, you need to call the FPG program
and specify the following parameters.
FPEG input.mpp4 CVIX264
CRF30 output.mpp4 MP4.
Next, the video compression process is
complete and the output.mpp4 file is
created. The output.mpp4 file size is a
little over 6 MB, but the original input
file was over 28 MB. As you can see,
there is a big difference.
