Default Scene Analyser

Hi,

A while ago on here (possibly over a year, maybe even two) someone
recommended a tool that would analyse and split a DV file into scenes based
on either timecode and /or frame content.

Anyone any recollection of what this was or even some suggestions for
alternative tools (ideally cheap or shareware)?

As background, I'm currently having a play around with quite a few trial
versions of different video editing software, some of which have this
feature (e.g Ulead Video Studio), others which seem to have it partially
(Vegas seems to scene detect on capture only, but not from an existing
file(?)), and so on to Premiere which does no scene detect at all. I've
been fairly impressed with VideoStudio but it is so slow, especially when
adding transitions etc and previews. I do a mixed bag of stuff, all very
amateur, and use the benefits of scene detection maybe 60-70% of the time
when knocking out holidays, birthdays etc when it comes in very handy. For
a couple of years I've been getting by quite happilly with Pinnacle Studio
for the simple stuff, and switching to Premiere for specific scenes, and
having now got a new PC, am in a bit of a re-evaluation phase. In a
nutshell I need something that can churn out run of the mill stuff easily
and QUICKLY, while still having the feature set for more advanced stuff.
Hence, why I'm considering the scene capture tool as a bolt on to possible
Vegas or Premiere.

Any suggestions greatly received. TA.

It's call tape logging and uses a pencil and paper.....

Scene detection software is for wimps ! :~)

Too right - I mean, why spend 30 mins capturing scenes automatically when
you could spend hours having fun doing it manually. It's like all these
other new-fangled inventions that dare to try to save time like dish washers
and the like, and computers that use Windows instead of good old fashioned
dos command line. Who invented video anyway - lazy good for nothings -
nothing wrong with a canvas and set of paints.

Seriously, I just fnd it convenient a lot of the time. I know it's not the
'professional way' but I tend to capture full tapes at a time, rather than
batch capture etc, and normally when I pause the camera I want a break in
the scene anyway. I'm not sure it actually saves me much time, as I go in
and edit each clip separately anyway, it just somehow seems to make the
editing more manageable.

Err, but who would use a washing machine that shrunk some cloths and
stretched others, resulting in someone having to spend hours putting it all
right after - you can log a tape in the time it takes to watch and you're
not going to attempt to edit without first finding out what you have on tape
and were it is - with tape logging you also only capture what you need and
not loads of what you only want to delete after capture.

Sounds like it !...

big snip

- you can log a tape in the time it takes to watch


end of snip


No you can't - unless you can read timecode frame accurately _on the
fly_. You are going to stop at each cut, spin back a little because you
actually overshot the cut, run up to it again, stop, pause, joggle to
find the actual cut frame, write down the timecode and shot details and
then re-start the player.

If you can do that in _real time_ then you are cleverer than most. Also,
think of the wear and tear on the player/camera with the shunting back
and forth.

I have used Scenalyzer and it makes a pretty good job of logging the
tape with a single, non-stop, pass.

If you prefer to log manually, it saves wear and tear by capturing to
the computer and logging there - assuming the transfer includes off-tape
timecode.

There is no need to be that accrete, you add 'x' number of frames / seconds
at the beginning and at the end of each clip capture and then 'top and tail'
the clip in the editor. At worst you might need to pause the tape.

That is what a VHS BITC copy is for....

With 'scene' cuts in all the wrong places no doubt, otherwise you wouldn't
have used the phrase "it makes a pretty good job of logging the tape", you
would have used the word 'perfect'.

How can anyone edit a tape without knowing what is on the thing and were it
is, if you're going to view the tape at least once before editing that you
might as well log and capture only what you need.

the computer and logging there - assuming the transfer includes off-tape

That statement just shows how little you understand :~(

Burned in Timecode still doesn't make it any quicker.

Actually, no. Have you tried it? You add _no doubt_ so you have tried
it? In my experience it got it right all the time. The only reason I no
longer use it is because my video is captured and then logged on the
computer. It takes the same time as making a BITC copy on VHS.

otherwise you
wouldn't have used the phrase "it makes a pretty good job of logging
the tape", you would have used the word 'perfect'.

Nobody can. But what you were saying was that you can log in real time
which I was questioning, and still do.

Really? Having been involved with broadcast video for 32 years.
