Default How does my very first edited video (using Shotcut freeware) look?

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


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.
