Mpg2Cut2 - Intro
Last Revised: 29 May 2009
Fault Tolerant, GOP level, binary editor
for basic cutting of Mpeg2 Program Stream files.
Handles very large files (64bit) captured from Digital Television broadcasts (DTV), including High Definiton (HDTV).
Enhancement to Symbiose / Dark Avenger's Mpeg2Cut
2 Based on DVD2AVI by Chia-chen Kuo.
This cutter is very suited to use with streams captured from
Digital Television broadcasts.
High
Fault Tolerance
The single biggest advantage of this utility is a high
tolerance of faults in the Mpeg stream. Some capture
cards deliver very faulty streams if you do not have good
reception. So many conventional utilities will not accept
them, and may crash. But MPG2CUT2 will accept a huge
amount of crud, without batting an eyelid, as long as our
display drivers don't mind being sent a bunch of crud..
Very
Fast Seeking
Quick skip forward or backward along the time line,
operating at the GOP level. GOP level cutters operate on
logical Groups Of Pictures, usually about half a second
long.
Fast
Binary Copy
Data is typically copied asis, with no re-compression
performed.
This here is a TEST version:
It
is still under development.
Mainly because....
Needs testing on a wider range of formats.
Some players don't like the joins.
(See note below regarding PVAStrumento and ProjectX).
The remaining known bugs are comparatively minor.

Rocket Jetty hosted by GOOGLE.
Let me know what problems you are having, and I will see what I can do. Try very hard to include a detailed description of the problem, and what led up to it. If compatibilty issues arise, what product does it relate to ?
Vague complaints are unlikely to be solved.
I do not feed trolls.
Differences between original MpegCut and Mpg2Cut2:
Highlights
of the new features in this development version:
Improved compatibility options for output to other applications.
Fault tolerance improved for bad DVB-T DTV files.
Interface via command-line parameter
for Windows Explorer Context menu .
Multiple clip selection into a single output file.
Multi-File Input is now reinstated, but is very basic.
Display image in correct aspect ratio
with zoom and
point & click centering.
Notes:
RTFM - The
download includes a Text file - please read it. It is your
documentation.
This download is a TEST version, still in development,
so don't expect perfection.
The program does NOT handle "Transport Streams" well.
Input files should be Program Stream or Elementary Stream format.
If you have a transport stream, then convert it using
PVAStrumento.
Testing has been on DVB-T standard files, not ATSC.
Mpg2Cut2 can only edit Mpeg-2 or Mpeg-1 - NOT Mpeg-4.
Mpeg-1 is only partially supported.
Originally based

If
you have a problem...
NOTE:- If you are planning on using the edited output
on a DVD,
OR if you have problems in playback, such as bad audio sync:
then I suggest that you ALSO use one of the format conversion utilities, which examine an Mpeg stream in detail, and adjust it to meet DVD or xVCD restrictions:

The recommended way to
create chapters,
is to save each clip SEPARATELY.
This way each clip becomes a separate chapter.
Minimum Requirements for Mpg2Cut2
The basic editing function does not use much CPU,
so you could get away with using a very basic machine.
I use a P-III 800 Mhz. This is plenty fast enough for editing Standard Definition files, as long as no other high-CPU tasks are running in the background.
For cutting High Definition (HD) Mpeg files, 800 Mhz is OK, but a little sluggish.
Previewing:
The preview function chews up a LOT more CPU than editing does.
600Mhz P3 would probably be minimum for smooth preview of a Standard Definition file.
If your video card does not support YUY2 overlay,
zoom out to reduce overhead of video traffic.
If you are using a slowish machine,
try turning ON the frame dropping option.
High Definition:-Smooth preview would probably need at least 2 Ghz even for a moderate bit rate HD Mpeg file. For the seriously high bit rates that some countries have, you probably need more than 3Ghz, at a guess.
On slower machines, HD preview will be a bit jerky.
Turn on the option to drop frames when behind (View menu), which allows HD preview on a MUCH more humble machine.

Pre-Alpha is very rough and ready.
Alpha or Beta not quite so bad.
