I don't understand your question.

Do you mean "How to display the size of an MP4 file" or

Do you mean "How to control the size of an MP4 file" ?

I want to size a file from to another file, then save the other file

found my answer, I was able to use a CSS style script to size it down
automagically in my website purpose since it was big enough for upward
sizing already

runtime 2m4sec runtime 2m4sec

original.mp4 == smaller.mp4
3MB 2MB

Q=1 Q=31 [quality parameter Q
Q=1 is best quality possible]

Like that, did you mean ?

That is "resizing". You can make a file
smaller by adjusting the quality parameter,
and trading a fuzzy picture for a smaller
file size.

Here, some people report their results of messing around.
This example illustrates a codec change, instead of
adjusting the Q value.

https://gist.github.com/lukehedger/277d136f68b028e22bed

ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 output.mp4

The statically compiled version of ffmpeg is available here.

https://ffmpeg.zeranoe.com/builds/

4.0.2
Windows 64 or Windows 32 (check your System control panel)
static

Then click the blue link below that. Most people have
64-bit Windows installed. Some older hardware can still
run Windows 10 with 2GB of RAM, and it's possible the
person installing Windows installed the 32-bit version
in that case. The second file should "work on anything"
if you want a guarantee it will work.

https://ffmpeg.zeranoe.com/builds/wi...n64-static.zip
or
https://ffmpeg.zeranoe.com/builds/wi...n32-static.zip

Unpack the ZIP. The program has no installer and is portable.
You can place ffmpeg.exe in the folder with the movie
if you wish. Then

Command Prompt (non-administrator is fine...)

or use Powershell (non-administrator), type "cmd.exe",
then do these two commands and so on.

cd /d C:\users\user name\Downloads\
ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 output.mp4

You will discover a world of tuning parameters, including
adjusting Q for even smaller files.

If you have really high quality input materials (noise
reduction by author), then great things should be possible.

There are a million programs with GUI interfaces
out there, if the Command Prompt command scares you.

Paul

I asked for experts to tell me, I am thankful one did

I'm not an expert on this, but I understand some
video content is stored at a standard resolution,
and if you set the video player frame on your
web page, a "scaling" operation will be done
by the browser. It's when you make
the displayed frame larger than the original
capture size, that it begins to look "pixelated".

It uses extra bandwidth, if you do it that way,
but it gives the viewer more freedom to view
the content.

I don't think people take 720x480 (SD) content and
resize it (in a video editor) to 320x240 or 160x120
for a small window on a web page. Instead, they probably
leave the video at the original size, and the browser scales
the view to the desired size. This leaves some room
for people to change the scaling setting of the
entire web page, and still enjoy the content
without resolution-based mutilation.

If you expect your audience wants to view the content
in HD (1920x1080), maybe that's an option, but I don't
see that when looking at gspot analysis of video content.

This tool is now 11 years old, but is still useful
if you collect video. It tell you, for example,
whether the OS has a codec currently installed to
view the content. (Which isn't necessary any more,
as programs like VLC have all the codecs inside VLC
itself.)

When gspot doesn't know what the video is, you
can use ffprobe from ffmpeg package. Here,
I've analyzed a video off a news web page
(Flash format of some sort).
