MPG2CUT2 - CONTROLS =================== The keyboard is the fastest, most flexible way to navigate, using the cursor arrow keys, as they have Auto-Repeat. Auto-Repeat allows fast visual search, by holding down the appropriate arrow key. But if you prefer to use the mouse, then you can navigate along the time line using either the slider or the toolbar buttons. TOOLBAR BUTTONS :- B = BMP Snapshot of current frame. + = Add selection to Clip List L = Luminance Adjust Alt-L = Toggle Lumniance Adjust on/off Shift-L = luminance setting Bold Ctrl-L = luminance setting Default Z = Zoom ? = Stop / = Forward Single Frame p- = Play Slow P = Play p+ = Play Fast p* = Play Extra Fast (no sound) [ = Mark "IN" point (START of clip) << = Jump Back < = Move back 1 GOP >> = Jump Forward ? = Move forward 1 GOP ] = Mark "OUT" point (END of clip) KEYBOARD COMMANDS :- The keyboard is the fastest way to use the program. To allow for people with different habits, there are 2 different configurations for keyboard commands: 1) Classic Mpeg2Cut 2) VirtualDub compatible (well... sorta) Not quite, because VDub has frame level navigation, while Mpg2cut2 is GOP oriented. Arrow keys navigate along time line ACTION CLASSIC VIRTUALDUB Forward one GOP UP RIGHT Back one GOP DOWN LEFT Back a lot LEFT UP Forward a lot RIGHT DOWN Next File Start Ctrl RIGHT Previous File Start Ctrl LEFT SHIFT - Magnifies each of the above keys PAGE UP = Backward quite a lot PAGE DOWN = Forward quite a lot Forward 1 Frame / (NB.

Mpg2Cut2 can only edit Mpeg-2 or Mpeg-1 - NOT Mpeg-4. Mpeg-1 is only partially supported. If you have a transport stream, then it is preferable to convert it to a Program Stream using PVAStrumento. Ability to correct a small range of errors in the program stream, such as missing headers or incorrect aspect ratio. User tailorable reminder messages. USAGE ===== The basic approach is to mark the "FROM" and "TO" points of the clip that you want to keep, and then save that selection to a new file. Repeat this for each clip that you want. If you are working with Digital Television files, run each of the saved clips through a correction program, such as ProjectX or PVAStrumento. Drag and Drop the resulting clips into your DVD Authoring package. This way each clip becomes a separate scene, with it's own thumbnail on the DVD menu. (Your DVD Authoring package may be different to this.) ALTERNATE APPROACH ------------------ If you are NOT planning on using the clips as individual DVD scenes, you can perform multiple clip selections before saving them ALL together as a SINGLE output file. BUT, at this stage the joining of clips is very crude, so this approach MAY NOT work in your environment. Some players do not like the rough joins. You will probably need to use either "ProjectX" or "PVAStumento" to change the output file to be compatible with non-DTV applications. SO USE THIS FEATURE WITH CAUTION ! See notes below regarding Multi-Clip output. ----------------------------------------------------------------- FEATURES -------- Detects and attempts to fix missing Pack and System headers when creating the output file. Does *NOT* fully support MPEG-1 format. NOR Transport Streams. You MAY be able to view these unsupported formats, you MAY be able to save a single selection cut, but DO NOT assume that unsupported formats will be usable. ALWAYS check the results. There is NO decryption capability, it will only work on non-encrypted files. So if you are trying to use it on a commercial DVD, and just get rubbish out, don't be surprised. There is an option to output as Demuxed Elementary Streams, but there is no recompression. The output is still essentially the same underlying Mpeg codec, only the container has changed. Ditto for CDXA RIFF wrapped Mpeg files. The RIFF container is stripped away, but there is no change to the underlying Mpeg data. This is NOT a converter. It cannot output to AVI or other formats. There are some adjustments to control information, the internal Mpeg data itself is just grabbed directly from the input. Naming a file as a VOB will *NOT* convert it a a DVD compatible file. Use other utilities like "PVASTRUMENTO" or "PROJECT X" for that. ------------------------------------------ Mpg2Cut2 is essentially a GOP level editor. A GOP is a "Group Of Pictures", which is usually around 13 frames, lasting around half a second when played. This typically corresponds to the minimum playable Video "Sequence". Selection is generally made at the GOP level, so accuracy is typically limited to about half a second of time, in the typical situation of "SEQ/GOP/KEY-FRAME/DELTA-FRAMES". The program allows for Sequences that do not have a GOP header, but the sequence must at least begin with a key frame. The program does NOT check for "Open GOPs", so you can get spoilage of the first and last GOP in a selection. The impact of this can be minimized by enabling the menu option: "Include TO frame" which will extend the clip to include the terminating Key frame. HOWEVER, this decreases compatibility with set-top DVD players. The program has only LIMITED support for compensating audio delay relative to the video stream, and is a controlled via Menu Output options: - "PARSE ENABLED" - "PARSING OPTIONS" - "AUDIO MATCHING" You need both these options on for audio adjustment to take place. I also recommend :- - "PARSING OPTIONS" - "DEEP PARSING" - "PARSING OPTIONS" - "ALIGN VIDEO" - "PARSING OPTIONS" - "ALIGN AUDIO" As this feature is experimental, I suggest you leave some extra fat at the start and end of your edit selection, to avoid losing some audio. The Audio delay, which is shown in milliseconds (ms), typically will be of the order of 20-500ms for DVDs, but over 1 second is not unusal in DTV, especially on High Definition files. So add AT LEAST one GOP at the end of the clip selection. For safety, , especially on HD streams, add 3 GOPs. Also remember that change of scene is NOT likely to coincide with a GOP boundary, so you should also add a padding GOP at the start of the clip. I.E. Start the selection BEFORE the scene change. Also, PVAStrumento tends to drop the first GOP of a clip, so it is safer to have an extra GOP at the start too. These are rules of thumb - adjust based on your own experience -------------------------------------------------------------------- **** CURRENT KNOWN PROBLEMS :- *1: Joins are very rough, when saving multiple clips into a single file. To allow for the possibility of rough joins, I STRONGLY suggest adding an extra GOP or two at the start and end of each clip. PVAStrumento tends to drop GOPs at the start and end, so all the more reason to leave on some extra. Options are available to make the join smoother. (See "Output Controls" below). Audio sync problems after joins, on some players. Try using the Parsing option: "Match Audio". Multiple selection ranges basically works, at least in MY environment. It MAY NOT be acceptable to YOUR system. If you have problems with the outp...
