VCD Cutter

Currently I am using Microsoft Windows 2000. I am facing a problem with *.DAT (A movie) file. It is about 50:00 minutes (non-stop) but what I want is from 2:00 to 4:00, how can i cut this down ? (What software should I use ? How big its size ?)

All your comment/answer will be appreciated.

p/s: Hopes the software is freeware.

It's most likely to be your computer, but if you have access to a more powerful computer then I suggest you try the video on it to make sure it's not the conversion.

Thanks for your comment !!
I got a question, how can I set the offset and it's length ? base on what ? milisecond ? second ?

After I set the offset and length, is it save the movie ?

Yes, the offset is in milliseconds.

After that you should choose
Audio -> Direct stream copy

And try to do a direct stream copy of the video also
Video -> Direct stream copy

And finally
File -> Save Avi

If you get an error about the video, then you have to compress the video. But try the direct stream copy to begin with and if it doesn't work then please come back and I will give further details.

Thanks for your reply !
I have just tested it. Finally its works !
My computer is Pentium MMX 200 MHz, seems that the sound/audio is not smooth, how can I solve this problem ?

After I set the Video -> Direct stream copy, I found that I can't preview it and it showed this problem:
The source video stream uses a compression algorithm which is not compatible with AVI files. Direct stream copy cannot be used with this video stream.

You can resample the video. I believe the instructions for this is found in the help for VirtualDub.

I was afraid of that.

Go to
Video -> Compression

And choose your favourite compression. If you have DivX installed it should show there (DivX MPEG 4 ;) Low-motion).

Then choose
Video -> Full processing mode

and
File -> Save Avi

If you don't have Divx installed then choose Microsoft MPEG 4 V1.

I'm sorry. Don't choose Microsoft MPEG 4 V1! It makes a very large file!

I'll try some codecs.

Compressing the audio seems to reduce the file size dramatically.

Audio -> Compression
Mp3, and the quality you prefer.

Audio -> Full processing mode


But I'll check on some other video codecs too.

Reducing the video size:

Video -> Filters -> Add -> 2:1

If you don't have the DivX codec installed then the codec you should use is
Intel Indeo 4.5, 5 or 5.11
Quality: 85
Force keyframes every: 10


Hope this helps.

I have succesfully configure the video !
But seems that the sound/audio still not smooth, what should I do ? I don't know how to resample it..

_marko_Commented:
When you compress the audio the downsampling can be done at the same time: Just choose the lower bitrate for the audio.

Do you have an opportunity to try the video clip on another computer? Just to make sure it isn't the conversion that is going wrong? (I assume the original video is OK).

Yes, the original video is OK.
But when I play the movie (*.dat file), seems that the sound/audio is not smooth as normal.

Is it the problem with my computer ? My computer is Pentium MMX 200 MHz
