On this page I briefly
explain how you can cut MPEG files (both MPEG-1
and MPEG-2 are supported) to multiple MPEG
clips using the TMPGEnc application by Hiroyuki
Hori (freeware version can be downloaded there). Originally
this appliation was called "TSUNAMI-MPEG
Encoder".
This tricks can be darn usefull when cutting VCD
or SVCD copies of a DVD.
Note: TMPGEnc is not
very fast, but you can get a free version, which is said to support
MPEG-1 only. However the Plus version is not too expensive ($48,
visit the Pegasus website
to order) either and does support MPEG-2 (not for free due to
license fees for using MPEG-2)!
Note: Screenshots are
TMPGEnc 2.57 Plus based. |

Before we start ... what do we need?
Well, naturally at least a MPEG-1 or MPEG-2
file.
Note: TMPGEnc supports transcoding to a
different format - the result is not always perfect and it takes a lot
of time ...
You will also need, naturally, TMPGEnc,
which you can download at the TMPGEnc
Website.
You can download a free version at their website - it
doesn't support MPEG2, for that you will need to buy the Pro version (I
do think it does support MPEG2 for a limited time).
Install the the Application before continuing.
Cutting a movies into pieces
In this example I assume we have one MPEG-2 file, which
we would like to cut into two pieces.
Note: we're not actually "cutting"
the movie into pieces. It's more that we make two or more copies of a
part of a movie.
Step 1: Start TMPGEnc
We use TMPGEnc Plus in this example since we are dealing
with MPEG-2 files. MPEG-1 files work in the same fashion.
Step 2: Goto MPEG-Tools
Select the "MPEG-Tools" from
the "File" menu. |
|
Now this window (the MPEG-Tools) appears:
Step 3: Goto the "Merge &
Cut" tab
Click the most right tab, called "Merge
& Cut".
In the field "Type"
you must set the proper file format (e.g. MPEG1, MPEG2, VideoCD, Super
VideoCD, etc).
Step 4: Open the movie (MPEG) file
Click the "Add"
button to add a movie. A file dialog will open and ask you which MPEG
file you would like to add.
Pick a file and click "OK".
Step 5: Goto Edit mode.
Click the file you just added in the center
file list (it will highlite) and click the "Edit"
button.
A window will now open showing you a "movie"
screen.
Step 6: Select the start position of
the movie clip
Use the slider (indicated below by the red A-arrow
in the screenshot below) to select your starting position (usually this
is the absolute beginning of the movie, but this can be any given position
you like).
Optionally, you can enter the start position manually
in the "Range:" fields, where the first field
inidicates the start position.
If you have positioned the slider on the right place,
click the accolade open button ('{') to fix the start
position.
Step 7: Move the slider to the end position of the
movie clip
The same slider we used in Step 6 is now used to mark
the end position of the first part to be cut from this movie.
Optionally, you can enter the end position manually
in the "Range:" fields, where the second (to)
field inidicates the end position of this cut.
Once you've found the position where you would like
to end, press the accolade close button ('}').
Step 8: [OPTIONAL] Write down the time
code
(only needed if you want to cut a movie
into multiple parts!)
Incase you would
like to copy this movie into two pieces, then now is the time to
write down the time code. The time code is found above the movie
(the "Range:" fields) ... you should
remember the second value as this indicates the end position of
clip 1.
This will be the starting point (Step 6) of the second clip! |
|
Step 9: Saving the result.
Now it's time to copy this movie clip to
a file. Click "OK" to leave this "movie"
window and return to the "Merge & Cut"
window.
In the "Output"
field (below the file list) you can either enter a filename manually or
click the "Browse" button to locate a good
place to store the mpeg cut. The original file will not be affected, but
it is a good practice to name it something like "MyMovie_part1.mpg"
(where "MyMovie" can be any title you like).
The next step is to click the "Run"
button. A window will appear showing the progress ...
When the new clip has been completed, you
will be brought back to the "Merge & Cut" window.
Step 10: The next CUT ...
If you started cutting the movie to get
multiple parts, then repeat Step 6 to Step 9 until you're
done cutting the movie.
For Step 6, use the END time (you did
write it down in Step 8, didn't you?) of the previous cut as a BEGIN time.
Tip: When creating a movie
that spans multiple disc, it might be pleasant for the viewer to see the
last few seconds of the previous movie clip being repeated on the next
disc (for example when swapping disc usign VideoCD or Super VideoCD).
