OT Maybe File date on video


M

I took 2 one min videos about 20 min apart. When I got home, I
plugged in my camera and used Windows Explorer to open the folder on
the camera and moved the two files to the desktop.

Both files have the time I moved them to the desktop. There seems to
be no way to tell which video I took first other than it's file name
has a lower number.

Why would the date change? That seems like a bug.

No, you're just not looking at the right thing. The time you're looking
at is the creation time of the files, i.e., when they were created on
your desktop (why not in a folder, I might ask...).

Look at the other times, like the modified times, or look at the
metadata, i.e., the tags.

No, it's not. The date/time you see is the date/time the file was
created on your desktop, not the date/time you created the file in your
camera. Right click on the icon, then on Properties, you should see
several dates on the first pane. One of them is the date of the original
file. In an ordinary Explorer window, you can display this date. Right
click next to the last column header, and you'll see a menu that among
other things shows Date Created. Click that. You can make all folders
show this via Folder Options.

Since you asked.......Because it was a 1 min clip of my neighbor's
dog. (It is a weenie dog, but it acts like a Doberman) I just took a
video of it to show my sister. I uploaded it to Youtube and deleted
it.

Actually it was 2- 1 min videos. I took one shot with my camera at a
lower quality and one shot with my camera at the highest quality.

The strange thing is that the one with the higher quality setting did
show up clearer, but did not increase the file size too much.
Sometimes it turns out much larger.

Thanks for the info


I was unsuccessful in getting him kicking up dirt. The reason I moved
the camera to another gap in the trees was to try again to get him to
kick up dirt. He puts up a good bluff sometimes.

BTW I had been on a 2 mile walk, but my breathing makes me sound like
I have just ran a race. I also take meds that make my hands shake
pretty bad.

Well, in that case, the _default_ behaviour has changed from XP and
earlier versions of Windows. On XP and '9x, the date shown on a _file_
copied from one place to another (assuming the source _had_ a clock,
which I assume this video camera does, if it's making files) was the
creation date of the original file. If, in 7, the date shown _by
default_ is the date of creation of the local copy, that default has
changed.

If 7 has added extra date fields to all files, then it may be that not
just the display default has changed, but the treatment of the creation
date field: if 7 is actually changing the creation date field, then for
any such file copied to a 7 machine and then copied back to an older
system, it will be impossible to determine the creation date of the
original (on that older system), which previously it would have been.
This would IMO be a backwards step, so I hope it isn't actually what's
going on.

(For some reason, _folders_ - on the older Windows - _do_ show the date
of the copy, if they didn't exist locally beforehand at least. I can see
the rationale for that, though it does seem inconsistent.)

OK, that makes excellent sense. I'll just have to eat my words :)

There are two settings, quality and data rate. If the data rate is
similar the file size shouldn't change much, since it's data rate times
time, so you'll get low quality at the same number of bits per second =
similar file size.

If I sound vague, that follows from my actual knowledge level...

It does remind me that I have theorized that some dogs are best
described as obsessive-compulsive. I have some tendencies that way, so
I can tell :)

My neighbor's young and lively Bichon Frisee used to make a lot of
noise around me, but over time we've gotten to know each other, and now
he's quite friendly.
BTW I had been on a 2 mile walk, but my breathing makes me sound like
I have just ran a race. I also take meds that make my hands shake
pretty bad.
I have a friend who has shaken (more accuratley, trembled) all his life
("Essential Tremor"), and it worried him until another friend of the
medical persuasion pointed out that some people are like that, and for
them it's normal & harmless. Not the same thing, I know.

My sig represents another problem, which affects, but doesn't stop, my
folk-dancing hobby.

I have to say that, with respect to file times, the teminology and the
display in Windows are, shall we say, confusing :)

(Actually, that would have been worth mentioning explicitly in my first
reply.)
