Isn't the mp4 composed of a series of bitmaps?


I don't know. That's why I asked!

A bitmap defines a grid of pixels. If you paint black
over a rectangle then those pixels are black. They
can't be two things. It's not like spraypainting.


Great. That's what I want to hear.

The only thing I wanted in the video was privacy.
The rest was easy.

A PNG is just a compressed bitmap with an alpha
channel option, which means one can specify a degree
of blending with the background when painting the
image in order to give an effect of transparency.

There are no layers. Didn't we talk about this recently?
Someone was asking about image layers. Images don't
have layers. Graphic editors can sometimes allow
working with layers, and they can save that data in their
own formats. But that's not an image with layers. It's
a record of digital edits. That function led someone to
think that image formats have layers. They do not. A
raster image is a bitmap. That's it.


PDN has such layers.
But not PNG.

PDN? you mean a proprietary Paint.Net file
format? That's what I'm talking about as a storage
format. There is no such thing as a raster image
(a bitmap, as opposed to mathematically produced
vector graphics) that has layers. I can save layers
in Paint Shop Pro with the PSP format, but it's not
an image with layers. It's just memory backup of what
you've done with the image. So if you want to save
without merging layers you can do that. But that is
not an image and it's not a format that you'd use
online or give to others. It's basically the stored data
for the "workspace" state, along with undo memory.

This is a lot like the text discussion: It helps to
understand some of what goes on underneath in
order to understand how to work with the medium.

Looks fine to me. I would have cut the music out. Wastes 10MB
out of the 26MB total, and adds nothing to content.


Thanks Shadow for that advice to cut the obnoxious free music.

In all honesty, I couldn't get Shotcut to cut the original audio track out,


ffmpeg -i wifi.mp4 -c:v copy -an wifimute.mp4

and a one, and a two, and ... it's done.
2.5 seconds on my aging computer ....
(keep a backup of the original in case you get a command
wrong).
You probably want a static build. Put the contents of /bin
somewhere in your path. Or just unpack the binaries to the folder you
are working in. You will need a command prompt.
I have no idea how restrictive win7 and 10 are if you are not
admin (I use XP) so ask someone that knows.

FFMPEG is pretty easy-going. It's portable. You can put it
practically anywhere. (C:\FFMPEG\bin works for me...)

The fun part, is crafting command line invocations for it.
Every time I use FFMPEG, I write down the command I used
and keep it in my notes file. You'd be surprised how many
times you refer to those notes later. If it takes you
three hours to figure out what command to use, writing
it down is a small additional price to pay.

*******

Right now, Zeranoe has both "nightly" builds and Release builds.
I tested a "nightly" a couple months ago, and it was broken.
Even though statically linked (in the static package), it was
missing DLL files. The "Release" version on the other hand,
was fine. A few years back, I could grab a nightly and
expect it to work. The developers seem to be adding stuff
to FFMPEG that's dragging in more DLLs for some reason.
And the nightly build hasn't been modified to handle
whatever they've done. This could get fixed at any time
of course, and I'm only including the warning so a person
with limited downloads, doesn't waste their time on the
nightly as their first choice.

Many years ago in a place far away, the nightly builds of a different
product were for people who already had the product installed, so the
nightly builds intentionally left out the parts that hadn't changed
since the last stable release.

Is it the same here, by chance? That would explain the missing dlls.

But these builds are supposed to be "static".

The executable is pretty big, so all the dependencies
are statically linked (in effect, all the DLLs look to be
inside the EXE, based on the size). It should not ask
for DLLs if built properly.

When it start whining about DLLs, you could hunt down
the DLLs... but if you did, you'd be admitting to being
a "builder" yourself. And building FFMPEG is no small project.
I think I tried that once. I like them prebaked now :-)
I'm not afraid to build Firefox or Thunderbird or Chromium,
but FFMPEG is a *lot* of work. You spend hours looking
at ./configure, noting down all the dependencies that
have to be built and put in your tree. I can't imagine
what a living hell it would be, to do that for
Windows DLLs.

I think I might have had a moment of weakness, and
when I saw it ask for the first DLL, I almost went
off on a hunt to look for it. But when the program
asked for a couple more DLLs, I said "naw, I've
seen this movie before". And moved on to using
the release version.

You're right about "layers" specifically, but what I was talking about is
"hidden stuff" like the username in a Word file or the EXIF GPS location or
EXIF thumbnail in a JPEG image.

All I'm asking is whether there is "hidden" information in an MP4 file that
I need to know about to remove ahead of time.

Meanwhile, I've created another video, this time of my second-favorite
Android software for graphing WiFi signals, where it was *much* easier to
redact since I got the hang of things and learned how to *reuse* each
block!

I also didn't add any obnoxious free music (as per universal request!), and
I left the original Android sounds in place (blips and that sort of thing).

More importantly, I learned to keep the video more stable, and I learned to
make all the editing cuts beforehand. I also learned it's easier to just
"ripple delete" (there are all sorts of deletes so you have to learn a new
vocabulary) any anomalies than it is to fix them. I also learned how to
make "presets" in my GUI so that I don't have to wade through a long list
of options. (e.g., the text box should be 200px by 25px with 8x16
characters, each centered horizontally & vertically, etc.)

I also added callout text to kind of sort of say what was going on (for
Paul, who humorously saw a video with blue boxes jumping around!).

The good news is that if you apply a "filter" over a long section, and then
later (inevitably) you find you need *more* filters in shorter sections of
that long section, when you chop up the section, the first filter gets
reproduced in each section, so that's a good thing.

The bad thing is you can only select one section at a time (I don't know
why it has that severe limitation), so you have to *think* top down when
you're applying filters!

And as I said before, you really really really have to not hit the keyboard
unless you know exactly what's selected and exactly where the play head is
at any given moment. Also, the playhead is at the *beginning* of the next
frame, so it "looks ahead", which you have to keep in mind when making
edits because I was constantly deleting things one frame off on the back
end of each section until I etched that fact into my brain.

One oddity is that you can't step by "frame" but you have to step by
hundredths of a second, where each step seems to be a different multiple of
hundredths of a second (I don't understand that yet).

I'll upload the second video for a look see when I finish the final edits.
I'll also test a second binary-upload/download site for us to find the best
for everyone.

You are completely correct in your assessment that it's a video of a
cellphone screen with some floating blue rectangles on it! (Your forgot it
also had an obnoxious free music overlay to cover up the grandkid's in the
background.)


Here's the second video for review of results where the goal was simply:
a. Record video/audio on Android 4.3 of the screen running an app
b. Copy that MP4 video from Android to Windows over the WiFi LAN
c. Edit the video by adding text callouts and redacting private information
d. Post the video to a no-registration upload site for others to view

The no-registration site of the first video of Fritz! WiFi signal strength
monitoring was "sendspace.com"; but people didn't like that site all that
much so I'm trying out filedropper.com for this second video of the "WiFi
Analyzer" Android capabilities that iOS doesn't have (for God knows what
reason Apple restricts iOS functionality so much - but that's an aside).

Here is the second video showing "redaction" using opensource Shotcut:
http://www.filedropper.com/wifianalyzersignalstrength

The first video showing Shotcut redaction was prior posted to sendspace:
https://www.sendspace.com/file/gvckbe

What do you think of the new Shotcut redaction results?
What do you think of this 2nd no-registration video upload/download site?

I do exactly the same thing. My "notes"are 10 KB large.
I had to look up that command line I posted to the OP,
couldn't remember if it was -an or -c:a 0
It's not something I use very often, but just the other day I
used it to re-encode a video's audio track. Some idiot made a mkv
with E-AC-3 and my TV couldn't play it.

He dropped XP support ages ago, so I'm using a version from
July, built by someone called "CoRoNe". That's the advantage of
open-source, there'll always be someone willing to compile stuff.

I've been using Shotcut for weeks now to make other videos where I thank

It's so refreshing to have Windows Usenet posters who are intelligent and
technical and intentionally helpful as we found here, which is in stark
contrast to the iOS gullibles in the iOS newsgroups for which the video was
made.

The sad observation is that the iOS apologists there *still* can't
comprehend that all their wild claims of iOS functionality were purely
fictional.

In fact, they repeatedly fabricated wholly non-existent iOS functionality,
which they claimed only an Android video would disprove.
https://youtu.be/7QaABa6DFIo

Even though a simple screenshot would disprove what the iOS apologists
claimed was iOS functionality, they still claimed that only a video would
prove that it wasn't faked!
Android: http://wetakepic.com/images/2017/10/11/2wifianalyzer.jpg
http://wetakepic.com/images/2017/10/11/fritz_wlan.jpg
iOS: http://wetakepic.com/images/2017/10/11/wifi_sweetspots.jpg

Hence, the videos were instrumental in pointing out to the iOS gullibles
that a speedtest wasn't the same functionality as a measurement of signal
strength (which they insisted was the claimed iOS functionality).

iOS video by the iOS apologists:

Android video:
WiFi Analyzer: http://www.filedropper.com/wifianalyzersignalstrength
Fritz: https://www.sendspace.com/file/gvckbe
Snit's brazen fabrication of *imaginary iOS functionality*:

The full thread is here, where a cognitive adult has to wonder why *none*
of the iOS apologists noticed the complete fabrications in the iOS video.
https://groups.google.com/d/msg/comp.mobile.ipad/-T7FEXIdU9Q/Dhy-LFH3AwAJ

What's strange about the iOS apologists is that they never seem to
comprehend actual facts - whereas the Windows people here always seem to
comprehend facts.

What a difference!
Thanks!

To _really_ thank us, could you stop posting rants about iOS people
_here_? (Probably anywhere.) I doubt many of us on _these_ newsgroups
are even that _interested_, let alone disagree.

(It's also likely that even if you posted them to iOS newsgroups
[assuming there are any such], they'd not be read beyond your first use
of the word "apologists". So _really_, it's not worth posting them _at
all_ - they don't "add to tribal knowledge" much if at all, to use one
of your favourite phrases.)

I know my reply is very late to the thread, so I apologize for that.

I've been tinkering around with kdenlive myself for making short
videos based on other video I've shot on different occasions and some
still jpeg shots I took. I downloaded the shotcut program the other
day but haven't actually had a chance to check it out. I actually got
the linux version as that's what I plan to run it on. I'm hoping it's
as straight forward as the page suggested it might be, pending the
variant of Linux I'm using meets the dependency requirements. Mine
may/may not, just depends. I'm also test driving minty freshness 18.3
KDE edition which I was surprised to discover is actually more
responsive (seems to be anyway) on an older machine that I've already
got Mate 17.3 DE on due to expected performance hits if I'd gone with
KDE instead. I was running it for hours on a live stick, but, I might
take the plunge and let it install on the machine I was experimenting
with it on, just to see what happens.

So, if I get this shotcut program up and going, I might have
questions concerning it. Kdenlive is for the most part self
explanatory and that's the primary reason I actually took 18.3 for a
test drive last night; as later editions of Kdenlive don't support
17.3 due to the underlying codebase it's built on. I've sadly ran
into a few popular? programs now that don't support it, despite it
having support officially until 2019. Annoying to say the least.
